In this episode of the Epigenetics Podcast, we talked with Ferdinand von Meyenn from ETH Zürich about his work on the interplay of nutrition, metabolic pathways, and epigenetic regulation. To start Dr. Meyenn recounts his pivotal research on DNA methylation in naive embryonic stem cells during his time with Wolf Reick. He explains the dynamics of global demethylation in naive stem cells, revealing the key enzymes involved and the unexpected findings surrounding UHF1—its role in maintaining DNA methylation levels and influencing the methylation landscape during early embryonic development. Dr. Meyenn then shares his perspective on the scientific transition to establishing his own lab at ETH. He reflects on his ambitions to merge the fields of metabolism and epigenetics, which is a recurring theme throughout his research. By investigating the interplay between metabolic changes and epigenetic regulation, he aims to uncover how environmental factors affect cellular dynamics across various tissues. This leads to a discussion of his recent findings on histone lactylation and its implications in cellular metabolism, as well as the intricacies of epigenetic imprinting in stem cell biology. Last but not least we touch upon Dr. Meyenn's most recent study, published in Nature, investigating the epigenetic effects of obesity. He provides a detailed overview of how adipose tissue undergoes transcriptional and epigenetic rearrangements during weight fluctuations. The conversation highlights the notion of epigenetic memory in adipocytes, showing how obesity is not just a temporary state but leaves lasting cellular changes that can predispose individuals to future weight regain after dieting. This exploration opens avenues for potential therapeutic interventions aimed at reversing adverse epigenetic modifications. References von Meyenn, F., Iurlaro, M., Habibi, E., Liu, N.

In this episode, Brian Joyce discusses a groundbreaking study that examines the link between DNA methylation and the incidence of cardiovascular disease and cancer across three major cohorts. The research identifies shared epigenetic signatures associated with both diseases, highlighting the need for further investigation into their functional implications and potential clinical applications in diverse populations.
In this week's episode of the Everything Epigenetics podcast, I'm joined by Dr. Charles Breeze, an expert in computational epigenetics. We talk about his inspiring journey into the field of epigenetics, his trailblazing research on kidney function across diverse ethnic groups, and the innovative tools he's developed to push the boundaries of epigenetic research.Dr. Breeze shares how his fascination with the complex interaction between environmental and genetic factors shaped his path into epigenetics. This passion led him to focus on understanding why certain populations are at higher risk for diseases like chronic kidney disease. His work has uncovered insights into the disparities in kidney disease risk among different ethnic groups, shedding light on genetic and environmental factors that had previously been overlooked.To address the challenges of inclusivity and precision in epigenetic studies, Dr. Breeze developed specialized tools that enhance the accuracy of Epigenome-Wide Association Studies (EWAS). These tools aim to improve how we analyze the impact of genetics and environment on health, helping researchers study epigenetic patterns across populations more effectively. His contributions are making it easier to identify how factors like diet, stress, and pollution affect gene expression, paving the way for more inclusive and equitable health research.Dr. Breeze earned his Ph.D. in computational epigenetics and genomics from University College London, where he was a Marie Curie fellow. He has also worked at top institutions like the University of Oxford, the European Bioinformatics Institute, and the Altius Institute for Biomedical Sciences in Seattle. There, he led the analysis and creation of important mouse genome data. Dr. Breeze has developed bioinformatics tools like eFORGE and FORGE2, which help analyze data from studies on how genes and the environment affect health (EWAS and GWAS). Dr. Breeze is a member of the Encyclopedia of DNA Elements (ENCODE) and the International Human Epigenome Consortium (IHEC).You'll learn about: - Dr. Breeze's early interest in genomics, sparked by reading "Genome" by Matthew Ridley - His significant findings from the 2021 study titled “Epigenome-wide association study of kidney function identifies trans-ethnic and ethnic-specific loci,” which revealed ethnic disparities in kidney function - The challenges faced in epigenetic research due to the lack of diversity in reference data and how this impacts research outcomes - Proposed solutions to increase diversity in epigenomic data, including community involvement and targeted data generation - How his bioinformatics tools, eFORGE and FORGE2, assist researchers in understanding the complex data from EWAS and GWAS studies - His future research directions, including studies on kidney cancer and the expansion of pathway analysis toolsSupport the showWhere to Find Us:Instagram Twitter Facebook Follow us on:Apple Podcast Spotify YouTube Visit our website for more information and resources: everythingepigenetics.com Thank you for joining us at the Everything Epigenetics Podcast and remember you have control over your Epigenetics, so tune in next time to learn more about how to harness this knowledge for your benefit.

We are entering a new phase of understanding how our social environments affect our biology, particularly how they influence the genes involved in brain development and function. This knowledge helps us see how experiences like stress, trauma, and isolation can cause changes at the molecular level that may increase the risk of mental disorders. On the other hand, we're also exploring how positive experiences induced by psychedelics, which create feelings of unity and insight, might lead to beneficial molecular changes.Most mental health disorders, whether psychiatric, neurodevelopmental, or neurodegenerative, arise from both genetic and environmental factors. Recognizing this, research now combines studies of these exposures with molecular biology to better understand how our behaviors and environments can directly impact our genetic expression, shedding light on why some people are more vulnerable to mental health issues. This field, known as behavioral epigenetics, explores how our experiences can shape our genetic makeup and influence our brain health.In this week's episode of the Everything Epigenetics podcast, Dr. Candace Lewis shares her insights into epigenetics, discussing how early life stress can affect gene regulation and how attachment and societal influences shape our biology. The conversation then turns to psychedelics, with Candace outlining the history and ongoing research into their potential as a therapeutic tool for mental health disorders. She explains the mechanics of psychedelic-assisted therapy and the importance of understanding its broader context.We then chat about the therapeutic possibilities of psychedelics and their role in epigenetics, and the importance of creating a safe environment for individuals to explore their emotions and experiences with psychedelics. Candace draws parallels between acute stress and the psychedelic state, suggesting that research into psychedelics could reveal important information about the epigenetic changes they induce. Lastly, Candace also mentions the Psychedelic Genome Project and the significance of collecting data to advance the field.Candace is currently the director of the BEAR Lab at Arizona State University aiming to acknowledge the harm caused by psychology and genetic sciences on minorly groups, increase diversity in training and study cohorts, and change policy to improve mental health for all.In this episode of Everything Epigenetics, you'll learn about: The Brain, Epigenetics, & Altered states Research (BEAR) labComplex relationships between experiences that shape cognition, mood, and behaviorHow stress, trauma, and lack of connection may lead to molecular changes that increase risk for mental disorders.Candace's editorial: What is up with psychedelics anyway?How epigenetics shed light on psychedelic therapyMDMA-assisted therapy DNA methylation of gene systems involved in addiction, cognition, stress, and immune functionHow DNA methylation is associated with MDMA-assisted therapy treatment response for severe PTSDThe hypothalamic-Pituitary-Adrenal (HPA) AxisSimilarities between the acute stress response and the psychedelic stateThe psychedelic Genome Project (PGP)Where to find Candace:- ASU profile- LinkedIn Support the Show.Thank you for joining us at the Everything Epigenetics Podcast and remember you have control over your Epigenetics, so tune in next time to learn more about how.
Professor Doudna was awarded the 2020 Nobel Prize in Chemistry with Professor Emmanuelle Charpentier for their pioneering work in CRISPR genome editing. The first genome editing therapy (Casgevy) was just FDA approved, only a decade after the CRISPR-Cas9 editing system discovery. But It's just the beginning of a much bigger impact story for medicine and life science.Ground Truths podcasts are now on Apple and Spotify. And if you prefer videos, they are posted on YouTubeTranscript with links to audio and relevant external linksEric Topol (00:06):This is Eric Topol with Ground Truths, and I'm really excited today to have with me Professor Jennifer Doudna, who heads up the Innovative Genomics Institute (IGI) at UC Berkeley, along with other academic appointments, and as everybody knows, was the Nobel laureate for her extraordinary discovery efforts with CRISPR genome editing. So welcome, Jennifer.Jennifer Doudna (00:31):Hello, Eric. Great to be here.Eric Topol (00:34):Well, you know we hadn't met before, but I felt like I know you so well because this is one of my favorite books, The Code Breaker. And Walter Isaacson did such a wonderful job to tell your story. What did you think of the book?My interview with Walter Isaacson on The Code Breaker, a book I highly recommendJennifer Doudna (00:48):I thought Walter did a great job. He's a good storyteller, and as you know from probably from reading it or maybe talking to others about it, he wrote a page turner. He actually really dug into the science and all the different aspects of it that I think created a great tale.Eric Topol (01:07):Yeah, I recommended highly. It was my favorite book when it came out a couple years ago, and it is a page turner. In fact, I just want to read one, there's so many quotes out of it, but in the early part of the book, he says, “the invention of CRISPR and the plague of Covid will hasten our transition to the third great revolution of modern times. These revolutions arose from the discovery beginning just over a century ago, of the three fundamental kernels of our existence, the atom, the bit, and the gene.” That kind of tells a big story just in one sentence, but I thought I'd start with the IGI, the institute that you have set up at Berkeley and what its overall goals are.Jennifer Doudna (01:58):Right. Well, let's just go back a few years maybe to the origins of this institute and my thinking around it, because in the early days of CRISPR, it was clear that we were really at a moment that was quite unique in the sense that there was a transformative technology. It was going to intersect with lots of other discoveries and technologies. And I work at a public institution and my question to myself was, how can I make sure that this powerful tool is first of all used responsibly and secondly, that it's used in a way that benefits as many people as possible, and it's a tall order, but clearly we needed to have some kind of a structure that would allow people to work together towards those goals. And that was really the mission behind the IGI, which was started as a partnership between UC Berkeley and UCSF and now actually includes UC Davis as well.The First FDA Approved Genome EditingEric Topol (02:57):I didn't realize that. That's terrific. Well, this is a pretty big time because 10 years or so, I guess starting to be 11 when you got this thing going, now we're starting to see, well, hundreds of patients have been treated and in December the FDA approved the first CRISPR therapy for sickle cell disease, Casgevy. Is that the way you say it?Jennifer Doudna (03:23):Casgevy, yeah.Eric Topol (03:24):That must have felt pretty good to see if you go from the molecules to the bench all the way now to actually treating diseases and getting approval, which is no easy task.Jennifer Doudna (03:39):Well, Eric, for me, I'm a biochemist and somebody who has always worked on the fundamentals of biology, and so it's really been extraordinary to see the pace at which the CRISPR technology has been adopted, and not just for fundamental research, but also for real applications. And Casgevy is sort of the crowning example of that so far, is that it's really a technology that we can already see how it's being used to, I think it's fair to say, effectively cure a genetic disease for the first time. Really amazing.Genome Editing is Not the Same as Gene TherapyEric Topol (04:17):Yeah. Now I want to get back to that. I know there's going to be refinements about that. And of course, there's beta thalassemia, so we've got two already, and our mutual friend Fyodor Urnov would say two down 5,000 to go. But I think before I get to the actual repair of the sickle cell defect molecular defect, I think one of the questions I think that people listeners may not know is the differentiation of genome editing with gene therapy. I mean, as you know, there was recently a gene therapy approval for something like $4.25 million for metachromatic leukodystrophy. So maybe you could give us kind of skinny on how these two fundamental therapies are different.Jennifer Doudna (05:07):Right. Well, it's a great question because the terminology sounds kind of the same, and so it could be confusing. Gene therapy goes back decades, I can remember gene therapy being discussed as an exciting new at the time, direction back when I was a graduate student. That was little while ago. And it refers to the idea that we can use a genetic approach for disease treatment or even for a cure. However, it fundamentally requires some mechanism of integrating new information into a genome. And traditionally that's been done using viruses, which are great at doing that. It's just that they do it wherever they want to do it, not necessarily where we want that information to go. And this is where CRISPR comes in. It's a technology allows precision in that kind of genetic manipulation. So it allows the scientist or the clinician to decide where to make a genetic change. And that gives us tremendous opportunity to do things with a kind of accuracy that hasn't been possible before.Eric Topol (06:12):Yeah, no question. That's just a footnote. My thesis in college at University of Virginia, 1975, I'm an old dog, was prospects for gene therapy in man. So it took a while, didn't it? But it's a lot better now with what you've been working on, you and your colleagues now and for the last decade for sure. Now, what I was really surprised about is it's not just of course, these hemoglobin disorders, but now already in phase two trials, you've got hereditary angioedema, which is a life-threatening condition, amyloidosis, cancer ex vivo, and also chronic urinary tract infections. And of course, there's six more others like autoimmune diseases like lupus and type 1 diabetes. So this is really blossoming. It's really extraordinary.Eric Topol (07:11):I mean, wow. So one of the questions I had about phages, because this is kind of going back to this original work and discovery, antimicrobial resistance is really a big problem and it's a global health crisis, and there's only two routes there coming up with new drugs, which has been slow and not really supported by the life science industry. And the other promising area is with phages. And I wonder, since this is an area you know so well, why haven't we put more, we're starting to see more trials in phages. Why haven't we doubled down or tripled down on this to help the antimicrobial resistance problem?Jennifer Doudna (08:00):Well, it's a really interesting area, and as you said, it's kind of one of those areas of science where I think there was interest a while ago and some effort was made for reasons that are not entirely clear to me, at least it fizzled out as a real focused field for a long time. But then more recently, people have realized that there's an opportunity here to take advantage of some natural biology in which viruses can infect and destroy microbes. Why aren't we taking better advantage of that for our own health purposes? So I personally am very excited about this area. I think there's a lot of fundamental work still to be done, but I think there's a tremendous opportunity there as well.CRISPR 2.0Eric Topol (08:48):Yeah, I sure think we need to invest in that. Now, getting back to this sickle cell story, which is so extraordinary. This is kind of a workaround plan of getting fetal hemoglobin built up, but what about actually repairing, getting to fixing the lesion, if you will?Eric Topol (09:11):Yeah. Is that needed?Jennifer Doudna (09:13):Well, maybe it's worth saying a little bit about how Casgevy works, and you alluded to this. It's not a direct cure. It's a mechanism that allows activation of a second protein called fetal hemoglobin that can suppress the effect of the sickle cell mutation. And it's great, and I think for patients, it offers a really interesting opportunity with their disease that hasn't been available in the past, but at the same time, it's not a true cure. And so the question is could we use a CRISPR type technology to actually make a correction to the genetic defect that directly causes the disease? And I think the answer is yes. The field isn't there quite yet. It's still relatively difficult to control the exact way that DNA editing is occurring, especially if we're doing it in vivo in the body. But boy, many people are working on this, as you probably know. And I really think that's on the horizon.Eric Topol (10:19):Yeah. Well, I think we want to get into the in vivo story as well because that, I think right now it's so complicated for a person to have to go through the procedure to get ultimately this treatment currently for sickle cell, whereas if you could do this in vivo and you could actually get the cure, that would be of the objective. Now, you published just earlier this month in PNAS a wonderful paper about the EDVs and the lipid nanoparticles that are ways that we could get to a better precision editing. These EDVs I guess if I have it right, enveloped virus-like particles. It could be different types, it could be extracellular vesicles or whatnot. But do you think that's going to be important? Because right now we're limited for delivery, we're limited to achieve the right kind of editing to do this highly precise. Is that a big step for the future?Jennifer Doudna (11:27):Really big. I think that's gating at the moment. Right now, as you mentioned, somebody that might want to get the drug Casgevy for sickle cell disease or thalassemia, they have to go through a bone marrow transplant to get it. And that means that it's very expensive. It's time consuming. It's obviously not pleasant to have to go through that. And so that automatically means that right now that therapy is quite restricted in the patients that it can benefit. But we imagine a day when you could get this type of therapy into the body with a one-time injection. Maybe someday it's a pill that could be taken where the gene editors target the right cells in the body. In diseases like that, it would be the stem cells in the bone marrow and carry out gene editing that can have a therapeutic benefit. And again, it's one of those ideas that sounds like science fiction, and yet already there's tremendous advance in that direction. And I think over the next, I don't know, I'm guessing 5 to 10 years we're going to see that coming online.Editing RNA, the Epigenome, and the MicrobiomeEric Topol (12:35):Yeah, I'm guessing just because there's so much work on the lipid nanoparticles to tweak them. And there's four different components that could easily be made so much better. And then all these virus-like proteins, I mean, it may happen even sooner. And it's really exciting. And I love that diagram in that paper. You have basically every organ of the body that isn't accessible now, potentially that would become accessible. And that's exciting because whatever blossoming we're seeing right now with these phase two trials ongoing, then you basically have no limits. And that I think is really important. So in vivo editing big. Now, the other thing that's cropped up in recent times is we've just been focused on DNA, but now there's RNA editing, there's epigenetic or epigenomic editing. What are your thoughts about that?Jennifer Doudna (13:26):Very exciting as well. It's kind of a parallel strategy. The idea there would be to, rather than making a permanent change in the DNA of a cell, you could change just the genetic output of the cell and or even make a change to DNA that would alter its ability to be expressed and to produce proteins in the cell. So these are strategies that are accessible, again, using CRISPR tools. And the question is now how to use them in ways that will be therapeutically beneficial. Again, topics that are under very active investigation in both academic labs and at companies.Eric Topol (14:13):Yeah. Now speaking of that, this whole idea of rejuvenation, this is Altos. You may I'm sure know my friend here, Juan Carlos Belmonte, who's been pushing on this for some time at Altos now formerly at Salk. And I know you helped advise Altos, but this idea of basically epigenetic, well using the four Yamanaka factors and basically getting cells that go to a state that are rejuvenated and all these animal models that show that it really happens, are you thinking that really could become a therapy in the times ahead in patients for aging or particular ideas that you have of how to use that?Jennifer Doudna (15:02):Well, you mentioned the company Altos. I mean, Altos and a number of other groups are actively investigating this. Not I would say specifically regarding genome editing, although being able to monitor and probably change gene functions that might affect the aging process could be attractive in the future. I think the hard question there is which genes do we tweak and how do we make sure that it's safe? And better than me I mean, that's a very difficult thing to study clinically because it takes time for one thing, and we probably don't have the best models either. So I think there are challenges there for sure. But along the way, I feel very excited about the kind of fundamental knowledge that will come from those studies. And in particular, this question of how tissues rejuvenate I think is absolutely fascinating. And some organisms do this better than others. And so, understanding how that works in organisms that are able to say regrow a limb, I think can be very interesting.Eric Topol (16:10):And that gets me to that recent study. Well, as you well know, there's a company Verve that's working on the familial hypercholesterolemia and using editing with the PCSK9 through the liver and having some initial, at least a dozen patients have been treated. But then this epigenetic study of editing in mice for PCSK9 also showed results. Of course, that's much further behind actually treating patients with base editing. But it's really intriguing that you can do some of these things without having to go through DNA isn't it?Jennifer Doudna (16:51):Amazing, right? Yeah, it's very interesting.Reducing the Cost of Genome EditingEric Topol (16:54):Wild. Now, one of the things of course that people bring up is, well, this is so darn expensive and it's great. It's a science triumph, but then who can get these treatments? And recently in January, you announced a Danaher-IGI Beacon, and maybe you can tell us a bit about that, because again, here's a chance to really markedly reduce the cost, right?Jennifer Doudna (17:25):That's right. That's the vision there. And huge kudos to my colleague Fyodor Urnov, who really spearheaded that effort and leads the team on the IGI side. But the vision there was to partner with a company that has the ability to manufacture molecules in ways that are very, very hard, of course, for academic labs and even for most companies to do. And so the idea was to bring together the best of genome editing technology, the best of clinical medicine, especially focused on rare human diseases. And this is with our partners at UCSF and with the folks in the Danaher team who are experts at downstream issues of manufacturing. And so the hope there is that we can bring those pieces together to create ways of using CRISPR that will be cost effective for patients. And frankly, we'll also create a kind of roadmap for how to do this, how to do this more efficiently. And we're kind of building the plane while we're flying it, if you know what I mean. But we're trying to really work creatively with organizations like the FDA to come up with strategies for clinical trials that will maintain safety, but also speed up the timeline.Eric Topol (18:44):And I think it's really exciting. We need that and I'm on the scientific advisory board of Danaher, a new commitment for me. And when Fyodor presented that recently, I said, wow, this is exciting. We haven't really had a path to how to get these therapies down to a much lower cost. Now, another thing that's exciting that you're involved in, which I think crosses the whole genome editing, the two most important things that I've seen in my lifetime are genome editing and AI, and they also work together. So maybe before we get into AI for drug discovery, how does AI come into play when you're thinking about doing genome editing?Jennifer Doudna (19:34):Well, the thing about CRISPR is that as a tool, it's powerful not only as a one and done kind of an approach, but it's also very powerful genomically, meaning that you can make large libraries of these guide RNAs that allow interrogation of many genes at once. And so that's great on the one hand, but it's also daunting because it generates large collections of data that are difficult to manually inspect. And in some cases, I believe really very, very difficult to analyze in traditional ways. But imagine that we have ways of training models that can look at genetic intersections, ways that genes might be affecting the behavior of not only other genes, but also how a person responds to drugs, how a person responds to their environment and allows us to make predictions about genetic outcomes based on that information. I think that's extremely exciting, and I definitely think that over the next few years we'll see that kind of analysis coming online more and more.Eric Topol (20:45):Yeah, the convergence, I think is going to be, it's already being done now, but it's just going to keep building. Now, Demis Hassabis, who one of the brilliant people in the field of AI leads the whole Google Deep Mind AI efforts now, but he formed after AlphaFold2 behaving to predict proteins, 200 million proteins of the universe. He started a company Isomorphic Labs as a way to accelerate using AI drug discovery. What can you tell us about that?Jennifer Doudna (21:23):It's exciting, isn't it? I'm on the SAB for that company, and I think it's very interesting to see their approach to drug discovery. It's different from what I've been familiar with at other companies because they're really taking a computational lens to this challenge. The idea there is can we actually predict things like the way a small molecule might interact with a particular protein or even how it might interact with a large protein complex. And increasingly because of AlphaFold and programs like that, that allow accurate prediction of structures, it's possible to do that kind of work extremely quickly. A lot of it can be done in silico rather than in the laboratory. And when you do get around to doing experiments in the lab, you can get away with many fewer experiments because you know the right ones to do. Now, will this actually accelerate the rate at which we get to approved therapeutics? I wonder about your opinion about that. I remain unsure.Editing Out Alzheimer's Risk AllelesEric Topol (22:32):Yeah. I mean, we have one great success story so far during the pandemic Baricitinib, a drug that repurposed here, a drug that was for rheumatoid arthritis, found by data mining that have a high prospects for Covid and now saves lives in Covid. So at least that's one down, but we got a lot more here too. But it, it's great that Demis recruited you on the SAB for Isomorphic because it brings in a great mind in a different field. And it goes back to one of the things you mentioned earlier is how can we get some of this genome editing into a pill someday? Wow. Now, one of the things that for personal interest, as an APOE4 carrier, I'm looking to you to fix my APOE4 and give me APOE2. How can I expect to get that done in the near future?Jennifer Doudna (23:30):Oh boy. Okay, we'll have to roll up our sleeves on that one. But it is appealing, isn't it? I think about it too. It's a fascinating idea. Could we get to a point someday where we can use genome editing as a prophylactic, not as a treatment after the fact, but as a way to actually protect ourselves from disease? And the APOE4 example is a really interesting one because there's really good evidence that by changing the type of allele that one has for the APOE gene, you can actually affect a person's likelihood of developing Alzheimer's in later life. But how do we get there? I think one thing to point out is that right now doing genome editing in the brain is, well, it's hard. I mean, it's very hard.Eric Topol (24:18):It a little bit's been done in cerebral spinal fluid to show that you can get the APOE2 switch. But I don't know that I want to sign up for an LP to have that done.Jennifer Doudna (24:30):Not quite yet.Eric Topol (24:31):But someday it's wild. It's totally wild. And that actually gets me back to that program for coronary heart disease and heart attacks, because when you're treating people with familial hypercholesterolemia, this extreme phenotype. Someday and this goes for many of these rare diseases that you and others are working on, it can have much broader applicability if you have a one-off treatment to prevent coronary disease and heart attacks and you might use that for people well beyond those who have an LDL cholesterol that are in the thousands. So that's what I think a lot of people don't realize that this editing potential isn't just for these monogenic and rare diseases. So we just wanted to emphasize that. Well, this has been a kind of wild ride through so much going on in this field. I mean, it is extraordinary. What am I missing that you're excited about?Jennifer Doudna (25:32):Well, we didn't talk about the microbiome. I'll just very briefly mention that one of our latest initiatives at the IGI is editing the microbiome. And you probably know there are more and more connections that are being made between our microbiome and all kinds of health and disease states. So we think that being able to manipulate the microbiome precisely is going to open up another whole opportunity to impact our health.Can Editing Slow the Aging Process?Eric Topol (26:03):Yeah, I should have realized that when I only mentioned two layers of biology, there's another one that's active. Extraordinary, just going back to aging for a second today, there was a really interesting paper from Irv Weissman Stanford, who I'm sure you know and colleagues, where they basically depleted the myeloid stem cells in aged mice. And they rejuvenated the immune system. I mean, it really brought it back to life as a young malice. Now, there probably are ways to do that with editing without having to deplete stem cells. And the thought about other ways to approach the aging process now that we're learning so much about science and about the immune system, which is one of the most complex ones to work in. Do you have ideas about that are already out there that we could influence the aging process, especially for those of us who are getting old?Jennifer Doudna (27:07):We're all on that path, Eric. Well, I guess the way that I think about it is I like to think that genome editing is going to pave the way to make those kinds of fundamental discoveries. I still feel that there's a lot of our genetics that we don't understand. And so, by being able to manipulate genes precisely and increasingly to look at how genes interact with each other, I think one fundamental question it relates to aging actually is why do some of us age at a seemingly faster pace than others? And it must have to do at least in part with our genetic makeup and how we respond to our environment. So I definitely think there are big opportunities there, really in fundamental research initially, but maybe later to actually change those kinds of things.Eric Topol (28:03):Yeah, I'm very impressed in recent times how much the advances are being made at basic science level and experimental models. A lot of promise there. Now, is there anything about this field that you worry about that keeps you up at night that you think, besides, we talked about that we got to get the cost down, we have to bridge health inequities for sure, but is there anything else that you're concerned about right now?Jennifer Doudna (28:33):Well, I think anytime a new technology goes into clinical trials, you worry that things may get out ahead of their skis, and there may be some overreach that happens. I think we haven't really seen that so far in the CRISPR field, which is great. But I guess I remain cautious. I think that we all saw what happened in the field of gene therapy now decades ago, but that really put a poll on that field for a long time. And so, I definitely think that we need to continue to be very cautious as gene editing continues to advance.Eric Topol (29:10):Yeah, no question. I think the momentum now is getting past that point where you would be concerned about known unknowns, if you will, things that going back to the days of the Gelsinger crisis. But it's really extraordinary. I am so thrilled to have this conversation with you and to get a chance to review where the field is and where it's going. I mean, it's exploding with promise and potential well beyond and faster. I mean, it takes a drug 17 years, and you've already gotten this into two treatments. I mean, I'm struck when you were working on this, how you could have thought that within a 10-year time span you'd already have FDA approvals. It's extraordinary.Jennifer Doudna (30:09):Yeah, we hardly dared hope. Of course, we're all thrilled that it went that fast, but I think it would've been hard to imagine it at the time.Eric Topol (30:17):Yeah. Well, when that gets simplified and doesn't require hospitalizations and bone marrow, and then you'll know you're off to the races. But look, what a great start. Phenomenal. So congratulations. I'm so thrilled to have the chance to have this conversation. And obviously we're all going to be following your work because what a beacon of science and progress and changing medicine. So thanks and give my best to my friend there at IGI, Fyodor, who's a character. He's a real character. I love the guy, and he's a good friend.Jennifer Doudna (30:55):I certainly will Eric, and thank you so much. It's been great talking with you.*******************************************************Thanks for listening and/or reading this edition of Ground Truths.I hope you found it as stimulating as I did.

Lead Story: Epigenome-wide association study on methamphetamine dependence Addiction Biology The authors of this study postulate that some of the biologic changes resulting from methamphetamine use may be associated with epigenetic changes from DNA methylation. Such associations have been seen in schizophrenia, mood disorder, obsessive-compulsive disorder, and Parkinson's disease. Subjects with methamphetamine dependence (n=24) as well as age and sex matched controls had an epigenome-wide analysis of DNA methylation and identification of sites where methylation differed between subjects with methamphetamine dependence and controls. Thirteen regions with differential methylation were found. Of particular interest was hypomethylation of the CNOT1 and PUM1 genes leading to alterations in mRNA metabolism similar to those seen in bipolar disorder and schizophrenia. These changes relate to symptoms in common such as psychosis. The authors conclude that symptoms seen in methamphetamine dependency may result from genetic changes similar to those in other psychiatric disorders.

In this week's Everything Epigenetics episode, I speak with Dr. Toinét Cronjé about what epigenetics can do for the field of epidemiology. Epidemiology is the study of the distribution and determinants of health-related states or events in populations and the application of this study to control health problems. By studying epigenetics and epidemiology in tandem, Dr. Cronjé seeks to understand patterns of diseases in populations, identify risk factors, and develop strategies to prevent or control health issues.More specifically, Dr. Conjé researches epigenetics in understudied populations including the association between DNA methylation and noncommunicable diseases and how DNA methylation clocks perform in these groups.By making the most of the data we have available at the moment (from high-income countries) and of opportunities provided to researchers like herself to work at leading universities like the University of Copenhagen, she hopes that we will get closer to finding the tools to ease the burden on the research communities in low and middle income countries (LMICs). If we can truly start to investigate data from LMICs can you imagine the richness of the information we will unearth?Many of the questions that we are struggling with will be easier to address if we have more diversity in research data sets (e.g. genetics, cultural, dietary, and environmental), as rich (diverse) data sets allow researchers to see more angles to approach their questions from that they might not have been able to see before.Dr. Cronjé's hope is to develop blood-based screening tools for a disease. Only then, when disease screening is accessible to all (e.g. through a blood test instead of intensive and invasive procedures) will we actually know what proportion of populations around the world actually suffer from diseases like these.Using that as a starting block we can finally proceed to addressing stigma and improving care.In this episode of Everything Epigenetics, you'll learn about: Toinét's unique backgroundOMIC epidemiologyWhat epigenetics does for epidemiology The importance of biobanks What we can tell you about yourself when investigating the epigenome using an archived sample from a biobankWhy it's important to research understudied populations What we can learn from low and middle income countriesWhat the research community is missing out on by not studying these groupsNoncommunicable diseases (NCDs)The association between DNA methylation and NCDsThe urban-rural divide which provides a unique opportunity to investigate the effect of the combined presence of multiple forms of environmental exposure on DNAm and the related increase in disease riskToinét's study on “Comparison of DNA methylation clocks in black South African men”Epigenetic age acceleration in the cardiometabolic disease among migrant and non-migrant African populationsAn editorial Toinét wrote in late November 2021 titled “Could unlocking methylation-based blood cell counts revolutionize epidemiology?”The current challenges in epigenetics that should be addressed in future workToinét's next epigenetic-based project Support the showThank you for joining us at the Everything Epigenetics Podcast and remember you have control over your Epigenetics, so tune in next time to learn more about how.

In this episode of the Epigenetics Podcast, we caught up with Björn Schumacher from the Institute for Genome Stability in Ageing and Disease at the University of Cologne to talk about his work on DNA damage in longevity and ageing. In this episode Björn Schumacher discusses his research on DNA repair and its impact on ageing. We explore his insights on the effects of DNA damage on transcription, the importance of studying development, and the role of histone modifications. We also discuss paternal DNA damage inheritance and the DREAM complex as a master regulator of DNA repair. The lab's goal is to enhance somatic DNA repair for healthier ageing and disease prevention.

Guests: Dr. Jimena Laporta, University of Wisconsin-MadisonCovering the topic of Fetal Hyperthermia, Dr. Jimena Laporta of the University of Wisconsin is the second podcast at the 2022 Tri-State Dairy Conference. This makes up part two of the conference series.Heat stress is known to be a significant issue for dairy cattle with both global temperatures and sensitivity of dairy cattle to heat rising. Dr. Laporta adds that negative effects of heat stress last for multiple generations and lactations. 1:16While heat stress affects all cattle, Dr. Laporta focuses on dry cows and their offspring, to provide a more holistic view of its effects. Beginning with the dry cow, she notes that heat stress lessens milk production, as it derails involution and redevelopment. 3:59Epigenetics play a role in fetal development in the dry cow - fetal hyperthermia creates changes in the DNA of the fetus, altering the epigenome. 11:22What are the effects of fetal hyperthermia short term and long term, as well as across generations?Dr. Laporta details many short term hallmarks of prenatal heat stress: the dam experiences a reduction in gestation length leading to a premature calf that has organ alterations, less of an immune response, less feed intake, and a higher core body temperature. 16:31Analyzing a large data set of cattle affected by fetal hyperthermia, Dr. Laporta finds long term effects. The daughters had lower survival rates and less production each lactation, which carried over to the next 2-3 generations. Heat stress effects cost the dairy industry $1.4 billion. 23:08Turning her focus to the molecular signature of heat stress, Dr. Laporta discusses her findings from inspecting a mammary gland, concluding that heat stress causes a lower cell proliferative capacity and negatively impacts protein synthesis. Both lead to compromised milk storage and synthetic capacity. 29:28Wrapping up, Dr. Laporta states that heat stress negatively affects growth, organ development, immune function, survival, longevity, and milk yield for multiple generations. However, she believes that management and nutritional intervention can reduce such effects. 36:58Please subscribe and share with your industry friends to bring more people to join us around the Real Science Exchange virtual pub table.

In this episode of the Epigenetics Podcast, we caught up with Paul Shiels from the University of Glasgow to talk about his work on the effects of environmental cues on the epigenome and longevity. Paul Shiels and his team focus on the question on how age related health is influenced by the environment. Factors like the socio-economic position, nutrition, lifestyle and the environment can influence the microbiome and the inflammation burden on the body which in turn can alter individual trajectories of ageing and health. The lab also tries to understand the epigenetic, molecular and cellular mechanisms that link the exposome to chronic age related diseases of older people. They have shown that (1) imbalanced nutrition is associated with a microbiota-mediated accelerated ageing in the general population, (2) a significantly higher abundance of circulatory pathogenic bacteria is found in the most biologically aged, while those less biologically aged possess more circulatory salutogenic bacteria with a capacity to metabolise and produce cytoprotective Nrf2 agonists, (3) those at lower socioeconomic position possess significantly lower betaine levels indicative of a poorer diet and poorer health span and consistent with reduced global DNA methylation levels in this group.

A new research paper was published in Aging (Aging-US) Volume 15, Issue 5, entitled, “Age-related methylation changes in the human sperm epigenome.” Advanced paternal age is associated with increased risks for reproductive and offspring medical problems. Accumulating evidence suggests age-related changes in the sperm epigenome as one underlying mechanism. In a recent study, researchers Laura Bernhardt, Marcus Dittrich, Andreas Prell, Ramya Potabattula, Charis Drummer, Rüdiger Behr, Thomas Hahn, Martin Schorsch, Tobias Müller, and Thomas Haaf from Julius Maximilians University, Partner Site Göttingen and Fertility Center Wiesbaden performed reduced representation bisulfite sequencing (RRBS) on 73 sperm samples of males attending a fertility center in Germany. “[...] we identified 1,162 (74%) regions which were significantly (FDR-adjusted) hypomethylated and 403 regions (26%) being hypermethylated with age.” There were no significant correlations with paternal BMI, semen quality, or ART outcome. The majority (1,152 of 1,565; 74%) of age-related differentially methylated regions (ageDMRs) were located within genic regions, including 1,002 genes with symbols. Hypomethylated ageDMRs were closer to transcription start sites than hypermethylated DMRs, half of which reside in gene-distal regions. In this and conceptually related genome-wide studies, so far 2,355 genes have been reported with significant sperm ageDMRs, however most (90%) of them in only one study. The 241 genes which have been replicated at least once showed significant functional enrichments in 41 biological processes associated with development and the nervous system and in 10 cellular components associated with synapses and neurons. This supports the hypothesis that paternal age effects on the sperm methylome affect offspring behavior and neurodevelopment. The researchers found it interesting to note that sperm ageDMRs were not randomly distributed throughout the human genome; chromosome 19 showed a highly significant twofold enrichment with sperm ageDMRs. Although the high gene density and CpG content have been conserved, the orthologous marmoset chromosome 22 did not appear to exhibit an increased regulatory potential by age-related DNA methylation changes. “Collectively, our data support the conclusion that age-induced methylation changes in the sperm epigenome contribute to the increased offspring disease susceptibility for neurodevelopmental disorders.” DOI: https://doi.org/10.18632/aging.204546 Corresponding Author: Thomas Haaf - thomas.haaf@uni-wuerzburg.de Keywords: ART outcome, DNA methylation, male germ cells, paternal age effect, human sperm epigenome Sign up for free Altmetric alerts about this article: https://aging.altmetric.com/details/email_updates?id=10.18632%2Faging.204546 Keywords - aging, ART outcome, DNA methylation, male germ cells, paternal age effect, human sperm epigenome About Aging-US Launched in 2009, Aging-US publishes papers of general interest and biological significance in all fields of aging research and age-related diseases, including cancer—and now, with a special focus on COVID-19 vulnerability as an age-dependent syndrome.

How old are you? A simple question, with a simple answer, right? Wrong. In this episode, we chat with the brilliant Ryan Smith, co-founder and VP of TruDiagnostic. TruDiagnostic is a global leader in tests that measure our epigenome and uncover what it tells us about biological age. At the risk of oversimplifying something quite complex, biological age describes the real rate at which your body is ageing and there are various ways to measure it. Ryan invited us to test out their TruAge test. We did the required blood spot tests, and sent them off and in this episode, we talked to Ryan about the results. Am I ageing faster, or slower than my biological age? And what does it mean? I'm not telling you here, take a listen and find out. Without giving anything away, seeing my results from this test has been fascinating. It has inspired me to maintain lots that I do and it has motivated me to explore new habits in my longevity quest. Epigenome testing is still in its infancy in the longevity field, but there is no doubt that this will be the future of how we look at health optimisation.

Abstract: Substance use disorder is a debilitating chronic disease and a leading cause of disability around the world. The nucleus accumbens (NAc) is a major brain hub that mediates reward behavior. Studies demonstrate exposure to cocaine is associated with molecular and functional imbalance in two NAc medium spiny neuron subtypes (MSNs), dopamine receptor 1 and 2 enriched D1-MSNs and D2-MSNs. Our previous reports showed that repeated cocaine exposure induced transcription factor early growth response 3 (Egr3) mRNA in NAc D1-MSNs, while reducing it in D2-MSNs. Here, we report our findings of repeated cocaine exposure inducing cell subtype specific bidirectional expression of the Egr3 corepressor NGFI-A-binding protein 2 (Nab2). Using CRISPR activation and interference (CRISPRa and CRISPRi) tools combined with Nab2 or Egr3 targeted sgRNAs, we mimicked these bidirectional changes in Neuro2a cells. Furthermore, we investigated D1-MSN and D2-MSN subtype specific expressional changes of histone lysine demethylases Kdm1a, Kdm6a and Kdm5c in NAc after repeated cocaine exposure. Since Kdm1a showed bidirectional expression patterns in D1-MSNs and D2-MSNs, like Egr3, we developed a light inducible Opto-CRISPR-KDM1a system. We were able to downregulate Egr3 and Nab2 transcripts and cause bidirectional expression changes in D1-MSNs and D2-MSNs similar to cocaine exposure in Neuro2A cells. In contrast, our Opto-CRISPR-p300 activation system induced the Egr3 and Nab2 transcripts and caused bidirectional transcription regulations in D1-MSNs and D2-MSNs. Our study sheds light on the expression patterns of Nab2 and Egr3 in specific NAc MSN subtypes in cocaine action and uses CRISPR tools to further mimic these expression patterns.

Despite public market investors shying away from preclinical companies amid biotech's bear market, large biopharmas have ramped up their deal making for early-stage assets and technologies and are willing to pay for access to new modalities, says BioCentury's Stephen Hansen on the latest BioCentury This Week podcast. Hansen and colleagues also discuss the implications of FDA's approval of gene therapy Zynteglo from bluebird bio Inc., and the latest advances and leaders in the field of epigenome editing.
Imagine that you are a college student, whose professors all magically decided to give exams and projects due on the same date. For some reason, you procrastinated until the last minute, and now you need to pull an all-nighter at the library. You begrudgingly head to the fourth floor of the library, prepared to stay awake with a bag full of your favorite candy bars and snacks, a Venti Starbucks iced coffee, and a couple cans of Red Bull. You finally leave the library with sleepy eyes just as the sun slowly rises above the horizon. On the actual exam, you feel very tired and have trouble concentrating. A couple days later, you get your not-so-great grade back for your exams and projects, and you make a promise to yourself that you will never make the same mistake. But two weeks later, you end up doing it again a couple weeks later. This all sounds too familiar, right?
The words bonding and attachment are common words, but what is the deeper meaning behind those words for new parents and their newborns or yet-to-be born babies? How can parents connect with their newborn in utero? How will the attachment before and after the baby is born affect the epigenomes, brain development, and future health of their little one? Laurel will take us on a fascinating dive into this topic to help us translate this information to our patients, students, and clients so that more new parents will understand the benefits of attachment to their new babies.

This week, please join author Ambarish Pandey and Editorialist Linda Peterson as they discuss the article "Frailty Status Modifies the Efficacy of Exercise Training Among Patients with Chronic Heart Failure and Reduced Ejection Fraction: An Analysis from the HF-ACTION Trial" and the editorial "Heart Failure With Reduced Ejection Fraction (HFrEF): ‘The Importance of Being Frail.'" Dr. Carolyn Lam: Welcome to Circulation on the Run, your weekly podcast, summary, and backstage pass to the journal and its editors. We're your co-hosts. I'm Dr. Carolyn Lam, associate editor from the National Heart Center and Duke National University of Singapore. Dr. Greg Hundley: And I'm Dr. Greg Hundley, associate editor director of the Pauley Heart Center at VCU Health in Richmond, Virginia. Well, Carolyn, this week's feature article, Heart Failure Reduced Ejection Fraction in Evaluating the Efficacy of Exercise Training. But guess what? It appears it may be more efficacious in those that have high Frailty Index scores, as opposed to those that may not. But before we get to our feature discussion, let's grab a cup of coffee and go through some of the other articles in the issue. Would you like to go first? Dr. Carolyn Lam: I would love to, and this first paper is one that defines epigenetic biomarkers of lifelong cardiovascular health exposure and really contributes to our understanding of their roles in cardiovascular disease development. First though, a little quiz for Greg. So, Greg, what does DNA methylation mean to you? Dr. Greg Hundley: Well, Carolyn, DNA methylation. So, what I understand is these methyl groups get involved with our DNA and actually affect change over time that leads to phenotypic expression of, maybe, new traits. But I don't know. Maybe I'm not quite up to date. Dr. Carolyn Lam: Oh, you're perfect. Indeed, DNA methylation is a widely characterized epigenetic modification, which means exactly as you said. It's a regulatory modification to our DNA induced by environmental exposures and can affect gene expression. And this is the topic of today's paper by Doctors Zheng, Hou, and Lloyd-Jones from Northwestern University Feinberg School of Medicine and their colleagues. So, what they did is they studied blood DNA methylation at over 840,000 methylation markers measured twice over five years in participants of the CARDIA study. Epigenome-wide association analyses on a clinical cumulative cardiovascular health score were then performed in both CARDIA and compared in the Framingham Heart Study. Dr. Carolyn Lam: The authors identified 45 midlife DNA methylation markers associated with clinical cardiovascular health metrics, such as body mass index, blood pressure, blood glucose, and total cholesterol longitudinally measured since young adulthood. The methylation markers were located in genes involved in lipid metabolism, insulin secretion, and cytokine production, which could not be fully attributed to genetic factors. So, they proposed and validated in summary a methylation-based risk score to promote a personalized cardiovascular disease risk evaluation beyond traditional cardiovascular risk factors. Dr. Greg Hundley: Oh, wow, Carolyn. Interesting, a methylation-based risk score to promote personalized cardiovascular disease risk evaluation. Wow! That's really exciting. Dr. Greg Hundley: Well, I'm going to go to the world of preclinical science, and just like last week where we had a really nice article on myocardial regeneration, this week, we've got another. And so, Carolyn, early neonates of both large and small mammals are able to regenerate the myocardium through cardiomyocyte proliferation for only a very short period after birth. This myocardial regenerative capacity declines in parallel with withdrawal of cardiomyocytes from the cell cycle in the first few postnatal days. No mammalian species examined to date has been found capable of a meaningful regenerative response to myocardial injury later than one week after birth. Dr. Carolyn Lam: Interesting. Now, I see that these investigators worked with possums. Could you tell me why they did that, and what did they find, Greg? Dr. Greg Hundley: Right, Carolyn. So, this work was led by Dr. Wataru Kimura from the RIKEN Center for Biosystems Dynamic Research and their colleagues. The reason they studied possums, so the marsupial possum maintains cardiomyocyte proliferation and a capacity for myocardial regeneration for at least two weeks after birth. Remember we stated before, all the other mammalian species, it's only one week after birth. So, this appears to be the longest postnatal duration of such a capacity among mammals examined to date, and AMP kinase signaling was implicated as an evolutionary conserved regulator of mammalian postnatal cardiomyocyte proliferation. Dr. Greg Hundley: And they additionally found that in a separate mouse experiment, the authors noted that the pharmacological inhibition of AMP kinase signaling was sufficient to extend the postnatal window of cardiomyocyte proliferation in neonatal mice, so really exciting work in the area of cardiomyocyte regeneration. Dr. Carolyn Lam: Wow, indeed! And I've learned now about possums. Thank you, Greg. Dr. Carolyn Lam: So, Greg, have you ever asked yourself, what is the frequency, penetrance, and variable expressivity of dilated cardiomyopathy-associated gene variants in the general population? Well, guess what? This next paper addresses just that in more than 18,600 UK Biobank participants who had undergone whole-genome sequencing, ECG, and cardiovascular magnetic resonance imaging. Dr. Greg Hundley: Wow, Carolyn, another really interesting study from the UK Biobank. So, what did they find? Dr. Carolyn Lam: So, this study is from Dr. Chahal from the Center for Inherited Cardiovascular Diseases Wellspan Health in Lancaster, Pennsylvania and colleagues, and they found that approximately one in six of adults with putative pathogenic variants in dilated cardiomyopathy genes exhibited early dilated cardiomyopathy features potentially associated with the genotype. And it's most commonly manifesting with arrhythmias in the absence of substantial ventricular dilation or dysfunction. Dr. Carolyn Lam: Among individuals with putative pathogenic dilated cardiomyopathy gene variants, ECG or CMR-detected early features were nearly four times more common than clinically manifest dilated cardiomyopathy or early features. Over 90% of subjects with these gene variants in dilated cardiomyopathy-associated genes did not have a prior history of dilated cardiomyopathy, and the overall clinical or subclinical penetrance of dilated cardiomyopathy-associated single pathogenic variants was highly variable between genes ranging from zero to 67%. And so, in conclusion, a genotype-first screening approach for dilated cardiomyopathy using a large genetic panel is currently not suitable in the general population due to incomplete understanding of the genetic architecture and reduced penetrance of the associated genes. Dr. Greg Hundley: Very nicely said, Carolyn. Wow! Well, let's take a look and see what's in the mailbag. And first, there's a Research Letter from Professor Huguenard entitled, “Frequency of Screening Detected Intracranial Aneurysms in Patients With Loeys-Dietz Syndrome.” And our own Bridget Kuehn has a really nice piece on Cardiology News. Dr. Carolyn Lam: Nice. There's also an On My Mind paper by Dr. Sattar, McGuire, and Gill entitled, “High-Circulating Triglycerides Are Most Commonly a Marker of Ectopic Fat Accumulation: Connecting the Clues to Advanced Lifestyle Interventions,” and an exchange of letters between Dr. Groothof and myself, Dr. Lam, regarding my article on “Efpeglenatide and Clinical Outcomes With and Without Concomitant SGLT-2 Inhibition in Type 2 Diabetes: An Exploratory Analysis of the AMPLITUDE-O Trial.” Dr. Carolyn Lam: Ah, that was awesome. Well, thanks, Greg. I am so excited to get to the future discussion that you queued us on so well, frailty in heart failure with reduced ejection fraction. Here we go. Dr. Greg Hundley: You bet. Dr. Greg Hundley: Welcome, listeners, to this July 12th, 2022 feature discussion. And we have with us today, Dr. Ambarish Pandey from University of Texas Southwestern Medical Center in Dallas, Texas, and Dr. Linda Peterson, an editorialist for this article from Washington University in St. Louis. Welcome to you both. Well, Ambarish, We're going to start with you. Could you describe for us basically the background information that went into the preparation of your study, and what was the hypothesis that you wanted to address? Dr. Ambarish Pandey: Thanks, Greg, for having me on this, and thanks to Circulation for publishing our article. Yeah, I think the premise for this study stems from the longstanding known benefit of exercise training in patients with heart failure with reduced ejection fraction. Now, that was shown in the HF-ACTION trial, where individuals with chronic stable heart failure with reduced ejection fraction underwent exercise training, and there was demonstrated benefit in quality of life and adjusted analyses. There was a protocol-specified adjusted analysis that did demonstrate improvement in some of the key primary endpoint. Dr. Ambarish Pandey: Based on these results, CMS has approved exercise training and cardiac rehabilitation in patients with chronic stable heart failure with reduced ejection fraction. However, despite this mandate from CMS and generally well-accepted benefits of exercise training in heart failure with reduced ejection fraction, the uptake of exercise training has been pretty low, and there's a lot of heterogeneity in the improvement in outcomes that is associated with exercise training. Dr. Ambarish Pandey: So, we wanted to see whether frailty, which is a well-characterized syndrome of reduced physiologic reserve and impaired homeostatic tolerance to stressors and is common in patients with HFrEF, we wanted to see how frailty modifies the beneficial effects of exercise training in HFrEF. And based on the existing literature and some of the prior works we have done, we hypothesized that individuals who are frail and who have more functional impairments are going to have more targets for improvement in their functional status and thus would be more likely to benefit from exercise training. And we looked at this in the HF-ACTION trial itself and using the Rockwood Frailty Index and the difference in primary outcome and treatment effect of exercise among frail and non-frail individuals. Dr. Greg Hundley: Very interesting, so really sort of a look back in HF-ACTION data. Describe a little bit more for us that study design, and then specifically, what was the study population that you used to test your hypothesis? Dr. Ambarish Pandey: Right. So HF-ACTION was a randomized control trial multi-centered that was sponsored by NHLBI and was conducted in the early 2000s and basically focused on chronic stable patients with heart failure with reduced ejection fraction who have not had a hospitalization in the past six weeks and have ejection fraction less than 35% and class II to IV. And these participants were randomized in one-to-one fashion to getting aerobic exercise training followed by some home-based exercise versus the usual care. Dr. Ambarish Pandey: And in our study, what we looked at was we looked at the effect modification by baseline frailty status on the treatment effect of exercise training. So, we calculated the frailty index, which is a well-established measure of frailty using a Rockwood Index Model, and we stratified patients by frail versus non-frail status based on a Frailty Index cut-off of 0.21, such that higher index identifies more frail participants. And then, we looked at how the treatment benefit of exercise training on different outcomes was differential across the frail and non-frail strata. We looked at qualitative interaction, and we also looked at the Frailty Index, so the continuous variable to assess the benefits of exercise across the spectrum of frailty in the study population. Dr. Greg Hundley: And so, before we get to your study results, how many patients were in your study? Give us an idea of what was the range in age, and then also the composition of sex? How many men? How many women? Dr. Ambarish Pandey: Right, so this is really important because that's addressed to the generalizability of the study. So, the study included around a little over 2,100 participants. The mean age was 59 years. 28% were women, and 32% were self-reported black individuals with chronic stable heart failure. That was the demographic distribution. The age was slightly younger than what you've commonly see in observational studies with heart failure, and that is largely because the study recruited patients who were able to do exercise training and were able to do exercise tests with peak VO2 and peak VO2 peak excess capacity assessment at baseline and follow-up. So, that kind of selected for a slightly younger population. Dr. Greg Hundley: Very nice. And so, what were your study results? Dr. Ambarish Pandey: So our study results are, indeed, pretty interesting. We identified that around 60% of patients with chronic stable heart failure with reduced ejection fraction who were in the trial were actually frail based on the Rockwood Frailty Index Model. And we observed that among the study participants, the exercise training was associated with significant improvement in the primary composite endpoint of all-cause hospitalization or death in frail participants, but not in the non-frail or less fail participants. And there was a significant treatment interaction, such that baseline frailty modified the treatment effect of exercise training for the primary composite endpoint. Dr. Ambarish Pandey: Now, this was largely driven by a significant reduction in all-cause hospitalization among frail individuals who underwent exercise training, and not so much by an effect on mortality. And we did not see a significant difference in the mortality component of the primary composite endpoint across frail versus non-frail status participants. So, in a nutshell, baseline frailty did modify the treatment effect, largely driven by substantial reduction in the risk of all-cause hospitalization among frail participants more than non-frail participants. Dr. Greg Hundley: And before we get to Linda in her interpretation of your study, Ambarish, did you see the same effects in frail men, in frail women? And also, what about in individuals that might be a little older versus those that were perhaps younger? Dr. Ambarish Pandey: That's a really important question, and we were a little bit limited to do further subgroups because we are dealing with around, I think, 2,000 participants and we had frail, non-frail, and we did not do a further subgroup stratification by sex or by age. The age range was rather narrow. It's 58 years plus/minus 13 years, so we didn't really have a lot of older individuals above 75, something like what REHAB-HF Trial has shown in the news, a recent trial. Dr. Ambarish Pandey: We couldn't address the question of whether the effect modification was further modified by sex or age, so I think that's the two-level interaction. But I think that is something that would be interesting to test perhaps in a pool analysis of multiple exercise training studies, which is something we are considering. Dr. Greg Hundley: Thank you. Well, listeners, now we're going to turn to our editorialist, Dr. Linda Peterson, from Washington University in St. Louis, and, Linda, very provocative results here, heart failure reduced ejection fraction. And certainly, we like to go to things like cardiac rehab, but we're hearing this it seemed to make a difference if you were frail versus not frail. Dr. Linda Peterson: Right, I think that's an important distinction here in this article as Ambarish has so eloquently put forth, and it's especially important because other articles have shown in looking at the PARADIGM-HF Study and ATMOSPHERE it appears that one out of two patients with HFrEF are actually frail. And so, the magnitude of these findings and the importance of these findings is highlighted by that study. And this frequency of frailty is roughly double that of community-dwelling adults who are over age 90, so we're thinking of frailty usually as much older adults, but in HF-ACTION, actually, the patients' average age was 60 in the patients with HFrEF. Dr. Linda Peterson: So, there's almost an accelerated aging phenotype we're seeing here in a large proportion of the patients who have HFrEF. I think this has an enormous impact on a lot of the patients that we're seeing with HFrEF, and we should be alerted to looking for frailty and potentially screening for frailty. And I think another highlight of this study is that it points out the importance of frailty because frail patients have a 50% higher risk of hospitalization and death, according to some other studies, particularly one by Faray and their group and also by Yang and their group. Dr. Linda Peterson: And so, it highlights the importance of getting patients who are frail with HFrEF into cardiac rehab or getting them some sort of aerobic exercise training. But paradoxically, frailty is also associated with a lower likelihood of those particular patients on getting into cardiac rehab and also getting on goal-directed medical therapy. And that was shown by Phil Ades and his group. So, I think the importance of these findings by Ambarish and his group are to be commended, and they're very important for a large proportion of our patients with HFrEF. Dr. Greg Hundley: Very nice. Well, let's turn back to Ambarish, and then follow up with Linda. Ambarish, what do you see as the next study that should be performed in follow-up to your study? Dr. Ambarish Pandey: I think that's a great question. And I think we are just beginning to realize the magnitude of impact that frailty has in the care of patients with heart failure. And this goes across the spectrum of ejection fraction, both HFpEF or heart failure with preserved ejection fraction and heart failure with reduced ejection fraction. Indeed, the burden of frailty is higher in patients with heart failure with preserved ejection fraction, and they are more of the accelerated aging phenotype. Dr. Ambarish Pandey: And I think the next study basically should look at a targeted approach to exercise training or category of intervention among patients who are most likely to benefit from it, which would be patients who have a high frailty burden or patients who have HFpEF. I think they go hand in hand when it comes to frailty and HFpEF. So, I think that's the next study to do is to see to what extent we can actually identify and target exercise training in the highest risk individuals who are most likely to benefit from it because that subset of highest modifiable risk is indeed identified by frailty and when you look at other subtypes by HFpEF which has a lot of high frailty burden. Dr. Greg Hundley: And, Linda, from your perspective, what do you see as the next study to be performed in this sphere of research? Dr. Linda Peterson: Yeah, I think this study really provides a springboard for future studies in HFrEF, in particular. One, what hospital interventions can be done in patients to get them moving more, and really assess is there a possibility of different types of exercises to get patients less frail even while they're in the hospital when they're enroute to going home? And then also, how do we have different mechanisms by which we can get more patients into cardiac rehab? Clearly, our national average of getting patients who qualify for cardiac rehab, which is a class I indication is 20% at best, and the aim from the AHA is 70%. Dr. Linda Peterson: There's a big gap there, so interventions looking at implementation and getting patients to cardiac rehab or looking at other types of aerobic exercise training, such as home-based cardiac rehab for patients who don't have a cardiac rehab center next to them, I think the field is wide open for different studies to springboard off of these findings. Dr. Greg Hundley: Very nice. Well, listeners, we want to thank Dr. Ambarish Pandey from University of Texas Southwestern Medical Center in Dallas, Texas, and our editorialist, Dr. Linda Peterson, from Washington University in St. Louis, for bringing us this research study, highlighting that among patients with chronic stable heart failure and reduced ejection fraction, that baseline frailty modified the treatment effect of aerobic exercise training with a greater reduction in the risk of all-cause hospitalization. Dr. Greg Hundley: Well, on behalf of Carolyn and myself, we want to wish you a great week, and we will catch you next week on the run.

In this episode of the Epigenetics Podcast, we caught up with Eleni Tomazou from St. Anna Children's Cancer Research Institute in Vienna to talk about her work on Epigenome-based precision medicine. The Tomazou lab studies Ewing sarcoma and the effects of Epigenetic factors on this disease. Ewing sarcoma is a type of cancer that affects bone and soft tissue of children and young adults, with a peak incidence at the age of 15. Ewing sarcoma is among the pediatric cancer types with the lowest survival rates and the development of novel therapies was obstructed by the limited understanding of the mechanisms behind the disease. Work done in Eleni Tomazou's group identified an epigenetic signature of Ewing sarcoma which, ultimately, lead to the possibility to diagnose Ewing sarcoma from liquid biopsies. The team is now looking to find actionable targets like enhancers to develop therapies, finding biomarkers to enable disease monitoring, and to further characterize these tumors to decipher intra-tumor epigenetic heterogeneity and characterize the developmental stage of the cell of origin.

In this episode of the Epigenetics Podcast, we caught up with Manel Esteller, Director of the Josep Carreras Leukemia Research Institute to talk about his work on Epigenetics and Epitranscriptomics in Cancer. The focus of Manel Esteller's research career and the focus of his current team is to characterize the epigenome and epitranscriptome of cancer cells in comparison to healthy cells, and their interplay. Ultimately, their goal is to use this knowledge to develop new therapies for cancer. Key achievements from the Esteller lab began with the discovery of the first miRNA that undergoes specific cancer-methylation associated silencing. The team further identified many more miRNAs that also play a role in cancer. Next to miRNAs, Manel Esteller studied the influence of lncRNAs, enhancers and DNA methylation on cancer development and progression, insights that may be used to develop cancer biomarkers and potential treatments.

In this episode of the Epigenetics Podcast, we caught up with Folami Ideraabdullah from the University of Chapel Hill to talk about her work on the environmental modulation of the epigenome during development. The lab of Folami Ideraabdullah focuses on studying how environmental factors modulate the epigenome. In particular the team investigates how Vitamin D levels influence epigenetic processes and, hence, the susceptibility for diseases like adipositas. Folami Ideraabdullah started with a genome-wide screen of DNA Methylation patterns that are observed after Vitamin D depletion. This work was then followed up by investigating the impact of Vitamin D depletion on mouse sperm DNA methylation. References Xue, J., Schoenrock, S. A., Valdar, W., Tarantino, L.

In Episode 3 of the Lifespan Podcast, Dr. David Sinclair and Matthew LaPlante dive deeply into the science of non-dietary interventions that mimic adversity and promote health. They begin by highlighting how different types of physical activity (i.e., low-intensity aerobic exercise, high-intensity aerobic exercise, and weight training) protect against age-related disease and enhance longevity. David and Matthew additionally highlight the latest evidence behind hyperbaric oxygen therapy, cold therapy, and heat therapy. As they discuss different adversity mimetics, they also explain how these interventions influence aging at the molecular and physiological levels.

In this episode, I am joined by Dr. David Sinclair, tenured Professor of Genetics at Harvard Medical School and an expert researcher in the field of longevity. Dr. Sinclair is also the author of the book Lifespan: Why We Age & Why We Don't Have To, and the host of the Lifespan Podcast, which launches January 5, 2022. In this interview, we discuss the cellular and molecular mechanisms of aging and what we all can do to slow or reverse the aging process. We discuss fasting and supplementation with resveratrol, NAD, metformin, and NMN. We also discuss the use of caffeine, exercise, cold exposure, and why excessive iron load is bad for us. We discuss food choices for offsetting aging and promoting autophagy (clearance of dead cells). And we discuss the key blood markers everyone should monitor to determine your biological versus chronological age. We also discuss the future of longevity research and technology.

We often associate illnesses and pains with old age. But our guest today reveals that the real cause of health problems is how you've lived your life. Accumulated amounts of stress can change our bodies down to the cellular level. Luckily, scientific discoveries such as peptide therapy can help our cells function better. Age is not the issue. If you take care of yourself, being older can mean being at the peak of your performance. In this episode, Dr William Seeds joins us to discuss how our cells function and how epigenetic influences can harm our bodies. He shares how peptides and peptide therapy play a crucial role in keeping ourselves healthy and treating injuries and illnesses! As we age, our bodies slowly lose their ability to perform specific functions, including growth hormone production. But with the right intervention, including peptide therapy, a 100-year-old can produce just as many growth hormones as someone a quarter their age! If you want to learn more about peptide therapy and how to age gracefully, then this episode is for you! Here are three reasons why you should listen to the full episode: Understand that taking care of our cells and helping them function properly is essential to living a healthier life. Discover why diseases are not a function of age but how we have experienced life and accumulated negative influences on our cells. Learn the importance of growth hormones and how peptides and peptide therapy can help with the neuroplasticity of our brains.

Episode Highlights [05:29] William's Background and His Father's Death William used to train with his father when he was a young athlete. Unfortunately, he lost his father on the track right before his eyes. He could not do anything to save him. His life changed drastically afterwards. As the eldest sibling, he had to take charge. William questioned how someone could seem like they're in the best of health but die so early. This thought led him to learn more about biochemistry and molecular biology. In the full episode, he shares the one book that jump-started his interest in biology and chemistry. [09:15] Shifting from Business to Medical School William shares that he was a business major, but he spent most of his college days researching and reading more about biochemistry. He became so good that he started helping people with their biology classes. When he graduated from business school, he knew that his path was in medicine. Along the way, he faced people telling him that he couldn't do it. However, he found a way to enter medical school by taking accelerated classes during the summer. These classes let him qualify for the entrance exam. People's advice, even disbelief, can help us achieve the impossible. Listen to the full episode to learn more about William's shift and how he even got early admission! [16:59] The Value of Constant Learning When William went into medical school, there were many things that didn't make sense to him. So he used to argue and get in trouble. He observed that the cell is more important than we give it credit for. While it's good to know its components, it's more important to understand how we can use it to treat illnesses. His work on nutrition and the cell built his orthopedic career and research on peptides. Eventually, he taught others about the application of peptides in their practices. Learning is not about being smart; it's about constantly working hard to gain and build knowledge. You have the power to explore what interests you and build expert-level knowledge based on the research you can find online. [25:32] What Are Peptides? Peptides are signalling agents that help maintain cellular health. There are many different names of peptides, depending on how and where they are made. They can be called hormones, enzymes, or more. Some of the most significant scientific discoveries started with the study of peptides. For example, insulin is one of the major peptides discovered back in the 1920s. Peptides may seem complicated, but you can make people understand them. William encourages everyone to learn more about it to make better decisions for their health, but it is the job of empowered people to educate people. [34:20] Peptide Therapy and Epigenetics Our genetics are unchangeable, but epigenetic influences can change how our cells transcribe and translate our gene's instructions. Epigenetic influences include things that affect us every day, like stress, aging, disease, and more. The work that William does, including peptide therapy, is all about epigenetics. Cells have their own intelligence. We just need to give them the ability to correct themselves. For instance, we need to maintain cellular redox — the thermodynamics of the cell. [37:02] What Happens When a Cell is Not Performing Well When epigenetic influences harm the cells' performance, they become senescent cells. Our bodies are programmed to kill these unhealthy cells, but this doesn't happen all the time. Senescent cells are the key to aging and diseases. When these cells establish themselves in the body, it is hard to get rid of them, especially since they can build up over time. [41:48] Aging and Growth Hormones As we age, the brain loses the capacity to release the same amount of growth hormone, which is the master regulator of our body. By the age of 30, we experience a slow decline in how much growth hormone we can produce, which decreases even more with age. However, you will never lose the capacity to create growth hormones. What dictates this production are the events in your life that affect your body and whether you have a buildup of senescent cells. Peptides and peptide therapy can help you regain the ability to release endogenous growth hormones based on your body's demand. [44:29] How to Increase Growth Hormones There are over 100 types of growth hormones. Each one is released based on the body's demand. Cells can recognise if synthetic growth hormones do not match the demand, and this can be harmful. One way we naturally release growth hormones is during sleep. [48:22] The Value of Growth Hormones Peptides can help not only with improving the increase of growth hormones but also with neuroplasticity. Certain peptides have specific uses. For example, Ipamorelin allows the secretion of growth hormone within 20 minutes of usage. This is typically used before sleeping and upon waking. Brain injuries tend to shut down more growth hormones. This goes to show how improving brain function involves many levels. Senescent cells suppress the stem cells' ability to perform repairs and can convert stem cells to senescent stem cells. Listen to the full episode to learn more about growth hormone pathways and how they improve function! [53:07] Age is Not the Issue Even if neural pathways have been damaged, the brain can build new ones. Age is not an issue; older people can still produce new neural pathways. There are a lot of aspects needed to create these pathways. It involves timing, planning, building momentum, and supplements. The gut plays an important role in recovering from brain injuries since it makes a lot of neurotransmitters. You also need to look at the cell membrane because you can lose certain phospholipids vital to conduction in axons and how neurons work. [56:49] There is Hope William's goal is to help people have enough knowledge to know that they can prevent themselves from things like a traumatic brain injury. Certain diseases take time to incubate, so you won't even know you're in its path until it's too late. We must take advantage of the knowledge that we can improve our cell's functions: we can change a cell to be more protective, more efficient, and keep it that way. We should aim to live our lives to the fullest capacity, no matter our age. William shares that even though he is already in his 60s, his capacity is at its peak. 7 Powerful Quotes [29:25] ‘If anybody tells you something is too complicated, you have to have a PhD to understand that, right away, you should call bullshit because it means [they] just can't teach well.' [29:48] 'We all have the same capability of understanding. So our job is to educate people of what they have out there and not to keep them thinking they can't learn this.' [44:58] ‘The cell knows what to make when the body has the demand.' [50:21] ‘Growth hormone has some tremendous downstream effects that are effective in so many ways, in helping people regain the ability to improve cellular metabolism in the brain.' [57:32] ‘We can change a cell to be more protective, more efficient, and keep that cell.' [57:41] ‘We're not looking to live at 150 years of age… We're looking to live every day of our lives at our fullest capacity.' [58:13] ‘There is just so much that people deserve to know that they can be doing it, that they can change their lives no matter what state they're in.'

In this episode of my Hungry for More series, I talk about the science behind epigenetics, specifically focusing on how our choices, behavior, and environment affect the expression of the genes we have in our DNA. Many of us feel like a victim of our own genes, and here, I remind you that you are your own fate's pilot – that you are more than the genetics encrypted in your body! I also share with you studies and other evidence which prove that through wiser health choices, we can actually get to take care of ourselves and of those who surround us as well.Highlights:Chemical modifications that can be made in order to affect the usability of one's genes in the body;Parents' choices that affect their health also affect the offspring's even before birth;Our choices and behaviors not only impact our DNA, but also impact the health and well-being of those around us.Check out previous episodes in my Hungry for More series if you haven't already! They'll really help you understand hunger.It is a great way of understanding why people struggle with their weight every day due to the lack of desire to eat certain things they enjoy eating as well as other factors such as stress levels, which affect the production of ghrelin hormone (the "I'm hungry" hormone).
