    Alzheimer's disease is a devastating neurodegenerative condition that slowly erodes memory, cognitive function, and the ability to perform even the simplest tasks. It's heartbreaking not only for those diagnosed but also for their loved ones as they watch a gradual loss of the person they knew. This is exactly how I felt in 2015 when I watched my grandmother be taken by this awful disease.The disease progresses as abnormal protein deposits (amyloid plaques and tau tangles) damage brain cells, leading to widespread brain shrinkage. Despite ongoing research, effective treatments remain limited, making Alzheimer's one of the most challenging and impactful diseases today. However, new research is uncovering fresh perspectives on its underlying causes. One emerging view is that beyond the traditional focus on protein deposits, epigenetic changes might play a crucial role in driving the disease.In this week's episode of the Everything Epigenetics podcast, Dr. Katz and I focus on his labs surprising journey that led them to believe that Alzheimer's disease is an epigenetic disease resulting from a loss of cell fate. Dr. Katz anticipates that his lab's work will advance drug discovery through epigenetics. If no other company exploits the work, his will, even though it currently exists only on paper. “Most of the epigenetic drugs are cancer therapies,” he notes. “More recently, drugs that target epigenetic enzymes have been pursued for a wide range of diseases, ranging from muscular dystrophies to Alzheimer's disease. Going forward, it will be exciting to see if epigenetic-based therapies prove to be effective against other diseases.”You'll learn about:Dr. Katz's interest in the development of the germline of the roundworm Caenorhabditis elegansHistone methylation and how this mechanism influences cell fate, as well as how this mechanism can go awryNeuroepigenetic mechanisms in diseaseNovel functions for epigenetics in the fields of Rett syndrome, Fragile X syndrome, and Alzheimer's disease researchHow the above discoveries underscore the vital importance of epigenetics in human neurological disordersThe first identified histone demethylase, lysine-specific demethylase 1 (LSD1)Why LSD1 is important What it means that LSD1 is required in the germ line to reprogram histone H3K4 methylationHow this pathway prevents epigenetic transcriptional memory from being inherited transgenerationallyHow this work can advance drug discovery in Alzheimer's disease CURE  (a program that Dr. Katz established with a nearby liberal arts college, Oglethorpe)How CURE promotes DEI in scienceChapters:00:00 Introduction to Epigenetics07:50 Hannah's Insights on Recent Research15:55 David's Perspective on Practical Applications25:18 The Impact of Lifestyle on EpigeSupport the Show.Where 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.

    In Europe, people aged 65 typically spend about half of their remaining years managing disabilities. Much of the existing research on aging has predominantly focused on identifying "cures" rather than exploring strategies for healthy aging. Dr. Esther Walton's is breaking new frontiers with the unconventional approach that aging begins at birth and should be approached through a comprehensive life course strategy that integrates studies of early development, adult psychiatry, and mental aging in later life. Her research program, BrainHealth, aims to fundamentally redefine, enhance, and distinguish mental aging throughout the lifespan by examining patterns of mental aging within the innovative framework of 'brain health'.With the BrainHealth program, Esther hopes to: 1) characterize brain health from birth to old age by establishing robust predictors of brain health in childhood and adolescence2) improve brain health by identifying modifiable protective factors to enhance brain health across the life course3) differentiate between physical and mental aging by developing a tissue-specific mouse model of lifelong brain health.If successful, this program will revolutionize the approach to healthy aging by permitting the early identification and alteration of unhealthy aging trajectories - a key societal challenge of our time.In this week's Everything Epigenetics podcast episode, we explore the fascinating intersection of brain health and epigenetics with Dr. Esther Walton, Associate Professor in Clinical Psychology at the University of Bath. Dr. Walton discusses her pioneering work on DNA methylation and its crucial role in brain development and mental health. This is especially exciting because little is known about the extent to which DNA methylation is linked to individual differences in the brain itself, and how these associations may unfold across development - a time of life when many mental disorders emerge.

    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.

    Personalized nutrition tailors dietary recommendations to an individual's unique biological needs, factoring in genetics, lifestyle, and health conditions to optimize health, prevent disease, and maintain overall well-being. Central to this approach is the role of epigenetics, which studies changes in gene expression that do not involve alterations to the DNA sequence but can be influenced by external factors such as diet.For instance, certain nutrients can affect DNA methylation patterns or modify histone structures, which in turn can activate or repress specific genes. Understanding how diet impacts these epigenetic changes is crucial for determining how an individual's gene expression can be influenced by their dietary choices. This knowledge allows for the development of tailored dietary advice that can promote better health outcomes based on an individual's specific genetic and epigenetic profile, making personalized nutrition a powerful tool in modern healthcare.In this week's episode of the Everything Epigenetics podcast, I discuss the connection between epigenetics and nutrition with Dr. Lucia Aronica. We explore how lifestyle factors like diet, exercise, stress, sleep, and environmental toxins influence epigenetic modifications. Dr. Aronica highlights the role of epinutrients, such as methyl donors and phytochemicals, in gene regulation and emphasizes key nutrients like folate and choline that are essential for methylation reactions. Our conversation also covers nutrigenetics, examining how genetic variations affect individual dietary responses, while cautioning against relying solely on genetic testing for nutritional guidance. Dr. Aronica advocates for integrating nutri-genetics with other health markers to develop personalized nutrition plans. We also discuss findings from the DIETFITS study about the impacts of low carb and low fat diets on gene activity and epigenetic modifications, and insights from the "You Are What You Eat" documentary series.

    Determining a newborn's due date traditionally relies on maternal reports of the last menstrual period and ultrasound scans. These conventional approaches can lead to uncertainties, especially when it comes to identifying deviations from normal fetal development that could impact research into the effects of preterm or post-term births on newborns.However, researchers, including Kristine Løkås Haftorn, have now developed a more precise method to ascertain newborns' gestational age through analyzing DNA methylation patterns in blood samples, utilizing machine learning. This is crucial because accurate knowledge of gestational age is fundamental for understanding the risks and implications of preterm and post-term births on infant health. Moreover, the ability to accurately determine gestational age in utero could revolutionize prenatal care by providing deeper insights into fetal development, potentially allowing for earlier identification of developmental issues and more tailored interventions to support healthy pregnancies.This breakthrough, driven by machine learning's ability to sift through and interpret complex epigenetic information, underscores the potential of combining technology with biology to enhance our understanding of human development. In this week's Everything Epigenetics podcast, I speak with Kristine about epigenetic gestational age prediction, how we can use gestational age clocks to look at developmental timing and how this can improve pregnancies, assisted reproductive technology (ART), and more.Kristine is particularly interested in epigenetic patterns in newborns, how these patterns are linked to development in the fetus and child, and how they can be affected by various exposures during pregnancy.In this Everything Epigenetics episode, you'll learn about:DNA methylation's role in fetal developmentGestational age and how is it linked to fetal developmentPredicting gestational age using epigenetics Why determining specific cell types responsible for an association between DNA methylation and a given phenotype importantHow Kristine is adjusting for cell type composition in her workWhat cell-type specific DNA methylation patterns are associated with gestational ageNucleated red blood cellsWhy Kristine believes nucleated red blood cells are the main cell type driving the DNAm-GA associationThe poor correlation observed between epigenetic age clocks for newborns and those for adultsHow we can use gestational age clocks to look at developmental timing and how this can improve pregnanciesAssisted reproductive technology (ART)Differences in disease in ART babies and traditional birth babiesEpigenome-wide association studies of ART Investigating CpGs on the X chromosomeHow Kristine's research will affect ART protocols in the futureWhere to find Kristine: X LinkedIn University Profile 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.

    Machine learning models that use DNA markers can estimate the age of biological samples. However, understanding why these markers change with age is challenging because it's hard to prove that these changes cause aging-related traits. In this week's Everything Epigenetics podcast, I speak with Kejun Ying who uses large datasets to find specific DNA markers that directly influence aging traits. We explore his recently published study which found casual CpGs that speed up aging and others that protect against it. Kejun and colleagues created two new models, DamAge and AdaptAge, to measure harmful and beneficial changes related to aging. DamAge, which indicates negative aging effects, is linked to several health risks, including higher chances of dying. AdaptAge, on the other hand, shows positive aging adaptations. Interestingly, only the negative changes seen in DamAge can be reversed by a process that makes aged cells young again.The research findings provide a detailed understanding of the DNA markers that truly affect lifespan and overall health as we age. This helps us develop more accurate aging biomarkers and evaluate treatments aimed at reversing aging, improving longevity, and understanding events that speed up the aging process.In this Everything Epigenetics episode, you'll learn about:Kejun's unique journey into the aging fieldOne of the biggest weaknesses of the epigenetic clocks (separating causation versus correlation)Mendelian randomization Casual inferenceWhy causality matters for aging biomarkersWhy it is  important to separate deleterious and protective changes in agingDamAge (casual aging clock based on damaging sites)AdpateAge (casual aging clock based on protective sites)The applications of DamAge and what AdpateAgeClockBase: a comprehensive platform for biological age profiling in human and mouseThe application of ClockBaseData privacy when using ClockBaseWhere to find Kejun: XLinkedInGoogle ScholarKejun Ying is a 4th year Ph.D. student in Harvard Medical School, Gladyshev lab.

    The Importance of the Imprintome with Dr. Randy Jirtle

    The idea of the impintome is still foreign to many people. So, let's start with a simple explanation.For the majority of genes, we inherit two functional copies—one from our mother and one from our father. However, imprinted genes follow a different pattern, as we inherit only one functional copy. Depending on the specific gene, either the copy from our mother or our father undergoes epigenetic silencing. This silencing process typically involves the addition of methyl groups during the formation of eggs or sperm.The epigenetic modifications on imprinted genes typically stay put  throughout the organism's lifespan but undergo a reset during the formation of eggs and sperm. Regardless of their origin, certain genes are consistently silenced in eggs, while others are consistently silenced in sperm.Soon after egg and sperm meet, most of the epigenetic tags that activate and silence genes are stripped from the DNA. However, in mammals, imprinted genes keep their epigenetic tags. Imprinted genes begin the process of development with epigenetic tags in place.Imprinted genes are not the only genes that bypass epigenetic reprogramming in the early embryo. Studying imprinting may help researchers understand how other genes make it through reprogramming without losing their epigenetic tags.–The field of epigenetics and the imprintome has grown exponentially in the past decade, largely fueled by Randy Jirtle's groundbreaking research. Picture this: his 2003 study on how nutrition impacts gene regulation is the single most talked-about paper in the history of science.

    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.

    You may be familiar with polygenic risk scores (PRS), but have you ever heard of methylation risk scores (MRS)? MRS are crucial to understand, as they're a tool that quantifies DNA methylation levels at specific genomic regions linked to particular conditions, shedding light on the potential impact of epigenetic modifications on disease susceptibility.In contrast, PRS calculates an individual's genetic disease risk by considering multiple genetic variants across the genome, often identified through genome-wide association studies. While PRS offers valuable insights into genetic predisposition for complex diseases such as heart disease and diabetes, it has its limitations, including the risk of false positives and challenges in clinical interpretation. The choice between MRS and PRS depends on the specific disease or research context and the available data, as both scores provide unique perspectives on disease risk.In this week's Everything Epigenetics podcast, Dr. Michael Thompson and I chat about the importance and benefits of MRS, how to calculate such scores, and how these scores compare to PRS. For example, in his recent paper, Mike discovered that MRS significantly improved the imputation of 139 outcomes, whereas the PRS improved only 22.We focus on the results from a study Mike published last year that showed MRS are associated with a collection of phenotypes with electric health record systems. Mike's work added significant MRS to state-of-the-art EHR imputation methods that leverage the entire set of medical records, and found that including MRS as a medical feature in the algorithm significantly improves EHR imputation in 37% of lab tests examined (median R2 increase 47.6%). His publicly available results show promise for methylation risk scores as clinical and scientific tools.Mike is currently in Barcelona working on using artificial intelligence to map and learn the biological effects of mutating everything (and anything) in every single position from a genetic variant to the change in splicing or to some other interesting phenotype.

    The reliability of testing epigenetic DNA methylation using Illumina beadchips is of paramount importance due to the specific intricacies of this technology. Illumina beadchips are widely used platforms for high-throughput epigenetic analysis, employing thousands of probes to measure DNA methylation levels at specific genomic loci. In this week's Everything Epigenetics podcast, Dr. Karen Sugden and I talk about how the reliability of these probes directly impacts the accuracy and validity of the results obtained.Keep in mind that in the context of Illumina beadchips, reliability refers to the consistent and accurate performance of each individual probe across multiple samples and experimental replicates. Each probe is designed to target a specific CpG site, and the methylation signal it generates must be dependable and reproducible.We discuss how reliable probes ensure the accuracy of DNA methylation measurements and how the reliability of probes becomes crucial for reproducibility when conducting large-scale studies using Illumina beadchips, such as epigenome-wide association studies (EWAS).Dr. Sugden and I also discuss how the reliability of probes on Illumina beadchips has implications for cross-study comparisons. For example, if the probes exhibit inconsistent behavior across different experiments or cohorts, it becomes challenging to compare results and draw meaningful insights from combined analyses.Furthermore, we chat about the efficient utilization of resources being linked to probe reliability. Unreliable probes might necessitate repeating experiments or allocating additional resources to validate results, potentially delaying research progress and increasing costs.In the context of epigenetic research, where subtle changes in DNA methylation can hold profound biological significance, the accuracy and consistency of data generated by Illumina beadchips are pivotal. Lastly, we explore Dr. Sugden's current research which includes how epigenetic clocks are associated with cognitive impairment and dementia and marijuana use. In this episode of Everything Epigenetics, you'll learn about: Dr. Karen Sugden's career Reliability and why it mattersHow unreliability arises in epigenetic researchThe process of measuring DNA methylation on Illumina beadchips (or microarrays) Technical errors that could arise when looking at DNA methylationKaren's paper titled “Patterns of Reliability: Assessing the Reproducibility and Integrity of DNA Methylation Measurement”How to untangle data from different beadchips (27K vs. 450K vs. EPIC 850K)What constitutes a reliable probe vs. an unreliable probe How to handle unreliable probesWho is at fault for unreliable probes If reliability is the same for every beadchipHow unreliability impacts epigenetic research How we can deal with unreliabilityThe value of repeated data Creating a “gold standard” work flow for processing epigenetic data How epigenetic clocks associate with cognitive impairment and dementia The connection between epigenetic clocks and marijuanaDr. Sugden's current research investigations Karen Sugden's profile at Duke - https://moffittcaspi.trinity.duke.edu/karen-sugden-0Support 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.

    Various aging clocks have been developed to quantify the aging process and predict age-related diseases. These biological age clocks are powered by different types of omics data and clinical biomarkers, and they're especially useful for observational studies, clinical trials, and basic science aimed at combating biological aging. Nonetheless, current research indicates that there is significant variation in aging, with deterioration and diseases affecting different organ systems and functional domains at different rates among individuals. While existing aging clocks can measure variations in the degree of aging, they do not account for variations in the way that aging occurs, such as in specific organ systems or functional domains.This is exactly what Raghav Sehgal has been working on during his career at Yale University - biological age clocks for 11 organ systems such as immune function, metabolic function, hepatic function, cardiac function, renal function and more. Knowing the age of your organs can provide several advantages over knowing just your biological age. Some of these include:Better understanding of disease risk: Knowing the age of individual organs can help identify which organs are aging faster and therefore at higher risk for developing age-related diseases. This information can be used to develop targeted interventions to prevent or delay the onset of these diseases.Precision medicine: Understanding the age of specific organs can help tailor medical treatments to an individual's needs. This can improve treatment outcomes and minimize side effects.Earlier detection of disease: Changes in the age of specific organs may be an early sign of disease. By monitoring the age of individual organs, it may be possible to detect disease at an earlier stage when it is more treatable.Improved health and lifestyle choices: Understanding the age of specific organs can help individuals make better lifestyle choices to improve organ health. For example, if a person's liver is aging faster than their chronological age, they may be motivated to adopt a healthier diet and lifestyle to improve liver function.In this week's Everything Epigenetics podcast, Raghav and I chat about his novel epigenetic aging clock called the “Systems Aging Clock” which is based on a combination of epigenetic changes and organ and bodily function-based mortality indices. Raghav is a PhD student at Yale University presently solving Aging using deep learning on multi-omic and multi-granular data. In this episode of Everything Epigenetics, you'll learn about: Raghav's background and how he became interested in biological systems and agingThe idea that a single number (epigenetic biological age) might not provide enough feedback for the heterogeneity with agingHow each of our organs age at different rates Using the age of your organs to guide preventative treatment Raghav's systems based approach to aging using “different organ systems or functional domains”The reason behind choosing the 11 organ systemsHow Raghav models unique epigenetic aging trajectories from 11 distinct groups of organ systemsOrgan systems Raghav would have liked to include in this research but couldn't because of limited data  The reason behind making an aging clock which combines the 11 organ system scoresHow he validated his system aging scores and aging clockApplications of the systems aging clockWhy you should look at your systems aging clock oSupport 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.

    Risk stratification in surgery is a crucial aspect of modern medical practice that involves assessing the potential risks and benefits associated with a surgical procedure for an individual patient. The goal is to optimize patient outcomes and improve decision-making by identifying those who may be at higher risk for complications.While vital for guiding clinical decision-making, current risk stratification in surgery faces several limitations. For example, incomplete or inaccurate patient data can impact the accuracy of risk assessments, and existing risk scoring systems may not encompass all relevant factors or lack predictive power for certain patient populations or procedures. Generalization of risk models can lead to inaccurate estimations when applied to different patient groups or healthcare settings, and the challenge of individualizing risk assessment for each patient remains. Despite these limitations, risk stratification continues to play a crucial role in surgical practice, guiding preoperative planning and perioperative care while facilitating informed discussions between patients and healthcare providers. Dr. Christopher Ames, Spine Tumor and Spinal Deformity Surgery Neurosurgeon at UCSF, has made extreme efforts to improve accuracy and individualization while addressing these challenges as medical research and technology advance.Surgery for spinal deformity has the potential to improve pain, disability, function, self-image, and mental health. These surgeries carry significant risk and require careful selection, optimization, and risk assessment.As many of you know, epigenetic clocks are age-estimation tools derived by measuring methylation patterns of specific DNA regions. The study of biological age in the adult deformity population has the potential to shed insight on the molecular basis of frailty and improve current risk assessment tools.In this week's Everything Epigenetics podcast, Dr. Christopher Ames and I talk about how risk calculators will play an increasingly important role in the future of healthcare and the limitations of current risk stratification in surgery. Our conversation also encompasses the utilization of adult deformity as a model for studying the aging demographic, adopting a multifaceted approach to stratify risks, and exploring the indications from data that aging biomarkers could contribute to evaluating surgical risks.In this episode of Everything Epigenetics, you'll learn about: Where Dr. Ames' passion stems fromLimitations of current risk stratification in surgeryPredictive modeling of outcomesNew variable identificationAdult deformity as a disease model for studying the aging populationUsing telomere length as a biomarker for Dr. Ames pilot studyThe difference between telomere length and epigenetic testing The study population Dr. Ames is investigating Dr. Ames' study on epigenetic age and spinal deformityAging markers for risk prediction in surgeryRisk stratification before epigenetic DNA methylation biomarkersA multi-variable approach for risk stratification The very first study to correlate epigenetic age and frailty scores in a prospective cohort of patients undergoing spine surgeryThe association of DunedinPACE and frailty, disability, and postoperative complications How Dr. Ames uses this data in his specialty The creation of a “bone aging clock”Dr. Ames future endeavors 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.

    According to Dr. Daniel Belsky at Columbia University, there are three limitations of epigenetic biological age clocks:1. Mortality selection Essentially, biological age measures may underestimate true aging because older participants represent slower agers. 2. Cohort EffectsBiological age measures may overestimate true aging because older participants carry an excess burden of early-life exposure to environmental toxicants, pathogens, poor nutrition, smoking, etc. 3. Uncertain Timing Biological age measures summarize total aging over the lifespan and cannot distinguish differences established early in development from ongoing processes of aging. As a result, biological clocks may have lower sensitivity to effects of intervention. So, you're probably wondering, how do we account for these limitations? Dr. Belsky and his team have created a tool that enhances the precision of measuring the rate of biological aging. Their work involved observing the health outcomes of 954 participants across four different age groups spanning from the mid-20s to the mid-40s. The researchers examined biomarkers believed to indicate how well various organs are functioning, as well as others linked to general health. Using this data, they devised an epigenetic "speedometer" to forecast how these values would change over time. This tool is called the DunedinPACE.As you may already know, the DunedinPACE measures how fast you are aging biologically for every one chronological year.  If you need an introduction to DunedinPACE, check out my episode with Dr. Terrie Moffitt HERE.In this week's Everything Epigenetics podcast, Dan Belsky and I take a deeper dive into why Biological Age is limited and how DunedinPACE overcomes these limitations. Dr. Belsky speaks with me about a geroscience model of aging-related burden of disease, DunedinPACE test-retest reliability, and why the DunedinPACE indicates a faster pace of aging in individuals with an older chronological age.We also discuss the effect of long-term caloric restriction on DNA methylation measures of biological aging in healthy adults from the CALERIE trial.

    As we age, physical fitness tends to decline. This decline can be attributed to various factors such as changes in body composition, reduced muscle mass and strength, decreased flexibility, and diminished cardiovascular endurance. Additionally, the body's ability to recover from physical exertion also tends to slow down with age.It has been well validated that the rate at which this decline occurs varies among individuals. However, those who maintain their physical fitness as they age experience a lower risk of various diseases and tend to enjoy longer lives. At the molecular level, changes in fitness and related indicators of functional capacity coincide with molecular markers of decline, which are believed to reflect underlying biological aging processes. Therefore, measurements of fitness offer a novel perspective on biological aging. Nevertheless, the measurement of fitness parameters presents challenges due to the need for in-person data collection by skilled experts utilizing specialized equipment. Moreover, remote data collection or studies involving stored biospecimens do not facilitate direct assessments of fitness. To overcome this limitation and facilitate the evaluation of fitness in such scenarios, Kristen Mcgreevy has developed blood-based DNAm biomarkers that encompass various aspects of fitness, including mobility (gait speed), strength (grip strength), lung function (forced expiratory volume in one second), and cardiovascular fitness (VO2 max). These biomarkers form the basis of a groundbreaking indicator known as DNAmFitAge, which quantifies biological age based on fitness levels. This research also highlights the influence lifestyle has on the aging methylome.In this week's Everything Epigenetics podcast, Kristen and I chat about the importance of physical fitness as we age, how she developed blood DNAm biomarkers for four fitness parameters, and how she created DNAmFitAge.

    I hate to break it to you, but yes - what your grandmother did directly influences how your DNA is regulated today. This is called epigenetic transgenerational inheritance. Epigenetic transgenerational inheritance refers to the transmission of epigenetic marks from one generation to the next. This phenomenon can occur through the germline and affect the development and health of future generations.To further explain, it is possible for environmental factors that affected our grandmother to influence our epigenetics through epigenetic transgenerational inheritance. For example, if our grandmother was exposed to a toxin that caused changes in her epigenetic marks, those changes could be passed down to subsequent generations. This could lead to an increased risk of disease or other health conditions in her grandchildren, even if they were not directly exposed to the toxin themselves.Additionally, lifestyle choices such as diet and exercise habits can also have epigenetic effects that can be inherited. If your grandmother had a poor diet or was sedentary, for example, this could have altered her epigenetic marks and potentially contributed to a higher risk of obesity or other metabolic disorders in her grandchildren.In this week's Everything Epigenetics podcast, Dr. Michael Skinner speaks with me about just that - epigenetic transgenerational inheritance, a term he coined in 2005. We discuss how Dr. Skinner and his team have shown that exposure to certain environmental factors, such as chemicals, nutrition, and stress, can cause changes in the epigenome that can be passed down through multiple generations. Dr. Skinner and I also chat about the mechanisms underlying this transgenerational epigenetic inheritance and the implications for human health and disease, including developmental disorders, obesity, and reproductive problems.In this episode of Everything Epigenetics, you'll learn about: Dr. Michael Skinner's history and how he became interested in things that cannot be explained by classical geneticsThe history of Epigenetics starting with Conrad Waddington who coined the term “Epigenetics” in 1942Epigenetic mechanism and marks (DNA methylation, histone modifications, chromatin structure, non-coding RNA, RNA methylation, and DNA adenine)How Dr. Skinner discovered epigenetic transgenerational inheritance Epigenetic transgenerational inheritance The role of the germ cell in this type of inheritance The limitations of genetic data in determining phenotypic outcomes Classical examples of epigenetic transgenerational inheritanceGenerational toxicology The work Dr. Skinner is performing now (F10 generations in rats) Environmental toxicants that have been shown to be associated with the transgenerational inheritance of increased disease susceptibilityHow different toxins can have an affect on our health today How other epidemiological factors can promote a transgenerational effect How Dr. Skinner's work has changed his own lifestyle Using epigenetic biomarkers for preventative therapeutic strategies to detect disease early The limitations of government policies regulating toxicant exposure The best way to move forward using epigenetics in the healthcare industryDr. Skinner's most recent work (which had over 500+ million reaches) looking at epigenetics in twins with different workout regimens How epigenetics can predict preeclampsia, preterm birth, male infertility, and moreThe lack of funding in this area of science 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.

    Cancer acts as an accelerator of aging. Furthermore, we know that cancer and cancer therapies can elicit aging-associated cognitive phenotypes and reveal or exacerbate underlying cognitive deficits, increase the risk of physical impairment, heart disease, diabetes and other chronic health conditions, and accelerate the hallmarks of aging. Dr. Christin Burd and her team, from The Ohio State University, have been asking key questions about just that… age-acceleration in cancer. To understand this further, they have been researching cancer therapies, T cells, senescence, and p16 and how they are related to epigenetic aging. T cells, senescence, and p16 are all known to play important roles in cancer development and progression. T cells are key players in the immune system's response to cancer, while senescence is a process that limits the proliferation of damaged cells and is implicated in aging and cancer. P16 is a tumor suppressor gene that is often mutated in cancer cells. By studying the relationship between epigenetic clocks and these key factors, we hope to gain a better understanding of how cancer cells develop and progress, as well as how they may be treated. Aging biomarkers, including epigenetic clocks, may provide important answers to some of the most pressing questions in cancer research today.In this week's Everything Epigenetics podcast, Dr. Christin Burd speaks with me about the importance of biomarkers and epigenetic clocks for older adults with cancer, as epigenetic clocks are currently not trained on cancer populations. We also discuss the development of a new ‘p16INK4a epi-clock' (that I am most excited about) which may allow for the measurement of different aspects of aging using the same platform. Being an educator at The Ohio State University, Dr. Burd is passionate about diversity, equity, and inclusion (DEI) initiatives in science. Dr. Burd continues to focus her research on identifying mechanisms to prevent melanoma and improve clinical outcomes in older adults with cancer.In this episode of Everything Epigenetics, you'll learn about: - How Dr. Burd became interested in cancer and what led her to the career she has today- Aging as a risk factor for cancer - What cancer therapies are causing aging and how that process can be mitigated - The collaboration between TruDiagnostic and Dr. Burd's team- Ohio State's CARE Clinic- The main mission of Dr. Burd's ;lab - Why we need biomarkers for older adults with cancer- Using T cells to measure Epigenetic Age- How T cell Epigenetic Age relates to clinical measures of faulty, cognitive decline, and toxicity risk- Details of the cohort Dr. Burd is investigating- How cancer therapies are related to Epigenetic Age- How cancer patients Epigenetic Age relates to outcomes - Senescence markers and how they are involved in Dr. Burd's work- The pros and cons of senescent cells- How to measure senescent cells- If T cell p16INK4a levels and Epigenetic Age are equivalent measures - How p16 levels are currently measured- How to get involved in the field of science - Dr. Burd's advice on navigating the transition from highschool to college- The grant application process and why there is a lack of understanding hereWhere to find Dr. Christin Burd:Dr. Burd's profile at The Ohio State University - https://u.osu.edu/burd-25/Twitter  - https://twitter.com/christinburdSupport 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.

    Maintaining muscle mass is crucial for healthy aging, as it is closely linked to overall physical function and quality of life. As we age, our bodies naturally experience a decline in muscle mass and strength, known as sarcopenia. This loss of muscle mass can lead to a range of negative health outcomes, including decreased mobility, increased risk of falls and fractures, and decreased metabolic rate. Additionally, loss of muscle mass can contribute to chronic conditions such as obesity, diabetes, and cardiovascular disease. By developing an epigenetic clock for skeletal muscle, Dr. Voisin and her colleagues have identified specific methylation patterns that are associated with muscle aging. This research not only sheds light on the biological mechanisms behind sarcopenia, but may also provide new targets for interventions aimed at preserving muscle mass and function in older adults.In this week's Everything Epigenetics podcast, Dr. Sarah Voisin and I focus on her 2020 paper which describes her development of a human muscle-specific epigenetic clock that predicts age with better accuracy than the pan-tissue clock. Yes - you heard that right… better accuracy than Dr. Steve Horvath's 2013 clock. Dr. Voisin and I also chat about the importance of skeletal muscle and how this relates to epigenetics and aging, the power of machine learning, and how identifying which methylation positions change as we age may give us insight into the underlying reason as to WHY we age rather than just HOW. She is now focused on creating an atas of epigenetics for all human tissues at the cellular level by combining 75,000 DNA methylation profiles across 18 tissues. In this episode of Everything Epigenetics, you'll learn about: How Dr. Voisin got her start in statistics and biology The importance of skeletal muscle tissue and how this relates to Epigenetics and AgingWhen to start exercising and moving your bodyThe importance of weight lifting How often we should be moving our body Why Dr. Voisin decided to develop this type of Epigenetic ClockThe limitations of the Horvath 2013 Clock as it relates to skeletal muscle The complications of data miningThe importance of collaboration and data sharing  How Dr. Voisin created her muscle-specific Epigenetic Clock The power of machine learningHow the muscle clock outperforms Dr. Steve Horvath's 2013 pan-tissue ClockDr. Voisin's epigenetic wide association studies (EWAS) she performedDifferentiated methylated positions (DMPs) in this studyDifferentiated methylation regions (DMRs) in this studyThe utility/application of the skeletal muscle Epigenetic ClockDr. Voisin's next big project (I'm so excited about her next project!!!) MEAT (muscle epigenetic age test)Where to find Dr. Voisin:Email: sarah.voisin@vu.edu.au Twitter: https://www.vu.edu.au/research/sarah-voisinGitHub account:https://github.com/sarah-voisinSupport 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.

    It's always a pleasure speaking with Dr. Habib, and in this podcast he doesn't disappoint. His mantra of “The right treatment, for the right patient, at the right time” has revolutionized the way healthcare providers should approach clinical care. He takes an integrated approach to healthcare, and notes that Next Health is not “married” to a single treatment method or restricted by conventional medical training. His practice incorporates a wide array of techniques and methodologies to get to the root cause of disease. In addition, he uses the best tools in the healing arts to provide precision diagnosis, primarily drug-free treatment, and treatment success that far exceeds traditional medicine. In this episode of the Everything Epigenetics podcast, Dr. Habib speaks with me about the details of integrating Epigenetic Methylation testing in his medical practice and how it changes his point of care when addressing aging, and why it's critical that more healthcare providers transition from the current state of our health system (sick-care) towards a model which focuses on functional and preventative medicine. In this podcast you'll hear:- Dr. Habib's approach to functional medicine using Epigenetic Testing- The journey of a functional medicine patient - A discussion of how to be in charge of your own health- The importance of trust between you and your healthcare provider- The science behind growth being great (while you're young) and the benefits of temporary stress as it relates to accelerated aging- How glucose and blood flow plays a major role in the aging process- About the need for healthcare providers to move from a disease/sick-care model towards a preventive, regenerative approachSupport 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.

    Epigenetic Scores for the Proteome with Danni Gadd

    The proteome is the collection of proteins that are present within a specific cell, tissue, or system within the body. Our circulating proteome refers to the proteins circulating in our bloodstream and is made up of proteins that are either produced in the circulatory system, or proteins that enter the bloodstream from other organs and tissues in the body.Why do we care about this? As we know, proteins are extremely important! They are influencer molecules that maintain our health, and they're also often the mediators of disease. Furthermore, protein biomarkers have been identified across many age-related morbidities. As proteins are the primary effectors of disease, connecting the epigenome, proteome, and time to disease onset may help to create new, predictive biological signatures.DNA methylation (DNAm) has been linked to the levels of proteins in our blood and the risk people have of developing chronic diseases. DNAm reflects the body's exposure to chronic stress and inflammation and while this process is dynamic, DNAm may be more stable than protein measures, which can be variable across multiple time points. DNAm scores for proteins could therefore be used to identify individuals with high-risk biological signatures, many years prior to disease diagnosis.In this week's Everything Epigenetics podcast, Danni and I chat about the circulating proteome, how machine learning can be used to create epigenetic scores, and how information from the blood can be used to stratify risk of disease. We focus on the results from a study Danni published last year that integrated epigenetic and protein measures from the blood to develop new biomarkers for disease prediction. Danni's work integrates these blood-based markers with the medical records of thousands of individuals to model disease onset. Danni is in the final year of her PhD, on the Wellcome Trust Translational Neuroscience programme at the University of Edinburgh. In this episode of Everything Epigenetics, you'll learn about: - Danni's neuroscience background and what got her interested in the field- Why the Wellcome Trust Translational Neuroscience programme at the University of Edinburgh was a perfect fit for her - A walkthrough of the central dogma - A review of DNA methylation - What the circulating proteome is and why it's important - The importance of proteins as biomarkers- The definition and importance of an EpiScore, a term that Danni coined- The strongest methylation signature we've seen to-date - Why using DNA methylation to predict protein levels may be useful- Considerations on using blood when investigating these markers - The definition and importance of protein quantitative trait loci - The cohorts Danni investigated in her paper “Epigenetic scores for the circulating proteome as tools for disease prediction”- How Danni applied machine learning methods in the context of cohort studies - How Danni created EpiScores for protein levels  - The value of using protein EpiScores for disease prediction and risk stratification - Inflammation as an important indicator of health- How EpiScores compare with polygenic risk scores- The importance of these risk scores in the context of age-related chronic disease - The challenges and future directions in Danni's work - How people can be involved in large-scale cohort studies- What's next for DanniWhere to find Danni: Twitter: https://twitter.com/dannigaddDanni's profile at the University of Edinburgh: 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.

    If you're human, I'm sure you've been stressed out at some point in time. Unfortunately, it is an inevitable occurrence during any stage of life. Not only does stress make you feel older, in a very real sense, it can speed up aging. But, what if you could reverse your increased aging following recovery from that stress? In this week's Everything Epigenetics podcast, Dr. Jesse Pognaik speaks with me about just that. We take a deep dive into his study which focuses on Biological Age being increased by stress and if it can be restored upon recovery. First, we discuss possible fluctuations in Biological Age by using a mouse model of heterochronic parabiosis. Then, how Dr. Poganik and his team applied a suite of advanced epigenetic age clocks in humans and mice to measure reversible biological age changes in response to various stressful stimuli including trauma surgery in elderly patients, pregnancy, and severe COVID-19. This incredible study uncovers a new layer of aging dynamics which should be considered in future studies. Furthermore, elevation of biological age by stress may be a quantifiable and actionable target for future interventions. Dr. Poganik is now actively working on answering the question, “Which clocks are actually measuring biological aging?”, as the current models do not discriminate between casual methylation changes. In this podcast you'll hear:The definition of stress in the context of Jesse's paperHeterochronic parabiosis defined and explainedThe connection between severe stress and aging using Biological Age clocksHow unexpected surgeries and elected surgeries affect Biological Age Improvement of Biological Age after surgeriesHow pregnancy affects Biological AgePregnancy and the connection to parabiosis The peak risks at the time of delivery of pregnancy in mice and human systems Recovery of Biological Age after pregnancySevere COVID-19 and the effects on Biological AgingPartial recovery upon COVID-19 patients after being discharged The need to study long COVID-19 How Dr. Poganik decided upon the stressors of interest The suite of Epigenetic Clocks used in the studyFirst generation clocks vs. second generation clocksThe precision of Epigenetic ClocksPrincipal component analysis algorithms The future of DNA methylation (DNAm) clocksThe need to understand which clocks measure what What is aging? Dr. Jesse Poganik Jesse Poganik was born and raised in Queens, New York, USA. He received his B.S. in Chemistry from the State University of New York at Stony Brook and M.S. and Ph.D. degrees in Chemical Biology from Cornell University. In 2020, he began his postdoctoral training in Prof. Vadim Gladyshev's laboratory at Brigham and Women's Hospital, Harvard Medical School.

    How fast are you aging, really? With Dr. Terrie Moffitt

    Measuring your Biological Age has been extremely popularized because of how highly correlated it is to almost every chronic disease and death. However, the Biological Age of a person is limited in the sense that it is a “historical-based” age, meaning it only captures how quickly you've been aging since your inception up until the present moment.Have you ever wondered how quickly you're aging at this very second? We need a metric that can tell us if we are currently aging in the right direction or the wrong direction. Because of Dr. Terrie Moffitt and other researchers at Duke, Columbia University, and the University of Otago there is now a new metric available that captures just that called the “DunedinPACE”. I've been lucky enough to know Dr. Terrie Moffitt through my company, TruDiagnostic, as we have the exclusive license to the DunedinPACE in all verticals. Dr. Moffitt's uplifting attitude and outlook of being “cautiously optimistic” when working with the Dunedin cohort and other researchers using the DunedinPACE makes for a fun and interesting conversation. In my first ever episode of the Everything Epigenetics podcast, Dr. Terrie Moffit speaks with me about the Dunedin cohort and how she and her team developed the DunedinPACE tool. Building the database took the international team over five decades (and counting), while they tracked biological changes in the bodies of 1037 New Zealanders who are members of the Dunedin Multidisciplinary Health and Development study, a project that began with their birth in 1972. When initially asking the National Institute of Aging, the peer reviewers thought that focusing on a 30 age cohort was incorrect. They thought there would be no variation and if there was it would be insignificant. Dr. Terrie Moffitt has recently traveled back to Dunedin, New Zealand with her team to collect the fifth round of data on the cohort participants, as they are now 52 years-old. In this podcast you'll hear:A discussion of the Dunedin cohort and the significance of its retention rateThe difference between DunedinPoAm and DunedinPACE How you can measure your pace of aging using the DunedinPACEThe importance of the relationship between an increased DunedinPACE and disease How Biological Age Clocks differ from the DunedinPACEThe application of DunedinPACE in clinical trials looking at anti-aging therapeutics, personal use, and surgical candidates for outcomesDr. Moffitt's point of view about being “cautiously optimistic” The type of sample collection and retest window required for DunedinPACEThe difficulty with obtaining methylation data from both blood and saliva samplesA quick overview of the CALERIE trial What factors accelerate and decelerate the DunedinPACE (according to the literature)The future of the DunedinPACE If you're interested in testing your DunedinPACE, you can use the code everythingepi for 12% off each product at TruDiagnostic.comIn addition, the algorithm to calculate DunedinPACE is on GitHub where any scientist with epigenetics expertise can access it to run their data for research purposes, so long as there is no commercial use intended.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.
