A major Alaska drilling project to tap 600 million barrels of oil has been blocked. A federal judge ruled in favor of Indigenous and environmental groups, finding that the permitting process has yet to fully consider impacts on the climate and polar bears.   Also, higher levels of the hormones estrogen and progesterone lead to a greater risk of breast cancer. Researchers at the Silent Spring Institute have shed new light on how chemical exposure can raise those hormone levels in women, and found that nearly 300 chemicals increased one or both hormones.   And an intricate web of roots and fungi connects life in an old growth forest, allowing ancient “mother trees” to nourish and protect their kin. A forest ecologist shares her research findings and reflects on how mother trees helped her through the challenges of motherhood and a cancer diagnosis.

Red and processed meat linked to increased risk of heart disease, study shows Oxford University, July 21, 2021 Globally, coronary heart diseases (caused by narrowed arteries that supply the heart with blood) claim nearly nine million lives each year1, the largest of any disease, and present a huge burden to health systems. Until now, it has been unclear whether eating meat increases the risk of heart disease, and if this varies for different kinds of meat. Researchers at the University of Oxford's Nuffield Department of Population Health have conducted the largest systematic review of the prospective evidence to date, including thirteen cohort studies involving over 1.4 million people. The study participants completed detailed dietary assessments, and their health was tracked for up to 30 years. The results are published today in Critical Reviews in Food Science and Nutrition. Overall, the evidence from the analysis indicated that: Each 50 g/day higher intake of processed meat (e.g. bacon, ham, and sausages) increased the risk of coronary heart disease by 18%. Each 50 g/day higher intake of unprocessed red meat (such as beef, lamb and pork) increased the risk of coronary heart disease by 9%. There was no clear link between eating poultry (such as chicken and turkey) and an increased risk of coronary heart disease. The findings may be because of the high content of saturated fat in red meat, and of sodium (salt) in processed meat. High intakes of saturated fat increase levels of harmful low-density lipoprotein (LDL) cholesterol, whilst excess salt consumption raises blood pressure. Both LDL cholesterol and high blood pressure are well-established risk factors for coronary heart disease. Previous work from the same research team has also indicated that even moderate intakes of red and processed meat are associated with increased risk of bowel cancer2. Dr. Keren Papier (Nuffield Department of Population Health), co-lead author of the study, said: "Red and processed meat have been consistently linked with bowel cancer and our findings suggest an additional role in heart disease. Therefore, current recommendations to limit red and processed meat consumption may also assist with the prevention of coronary heart disease." Dr. Anika Knüppel, from the Nuffield Department of Population Health and the other co-lead author of the study, added: "We know that meat production is a major contributor to greenhouse gas emissions and we need to reduce meat production and thereby consumption to benefit the environment. Our study shows that a reduction in red and processed meat intake would bring personal health benefits too." Currently in the UK, about 10 in 100 people would be expected to eventually die from coronary heart disease. Based on the findings from the present study and current red and processed meat intakes in the UK,4 if all these 100 people reduced their unprocessed red meat intake by three-quarters (for example from four times a week to one time a week), or if they stopped consuming processed meat altogether, deaths from coronary heart disease would decrease from 10 in 100 down to 9 in 100. The studies involved in this analysis were mostly based on white adults living in Europe or the U.S.. The research team say more data are needed to examine these associations in other populations, including East Asia and Africa.   C is for Vitamin C -- a key ingredient for immune cell function Harnessing the combined power of Vitamin C and TET proteins may give scientists a leg up in treating autoimmune diseases   La Jolla Institute for Immunology and Emory University, July 22, 2021 You can't make a banana split without bananas. And you can't generate stable regulatory T cells without Vitamin C or enzymes called TET proteins, it appears.  Regulatory T cells (Tregs) help control inflammation and autoimmunity in the body. Tregs are so important, in fact, that scientists are working to generate stable induced Tregs (iTregs) in vitro for use as treatments for autoimmune diseases as well as rejection to transplanted organs. Unfortunately, it has proven difficult to find the right molecular ingredients to induce stable iTregs. Now scientists at La Jolla Institute for Immunology and Emory University School of Medicine report that Vitamin C and TET proteins can work together to give Tregs their life-saving power.  "Vitamin C can be used to stabilize iTregs generated in vitro," says LJI Instructor Xiaojing Yue, Ph.D., who served as co-first author for the EMBO Reports study. "We hope that these kinds of induced Tregs can be used in the future for treatment of autoimmune diseases and organ transplantation." The recent study, led by LJI Professor Anjana Rao, Ph.D., and Emory Instructor Benjamin G Barwick, Ph.D., builds on the previous discovery that Vitamin C can enhance the enzymatic activity of TET proteins and prompt the generation of stable iTregs under lab conditions. This finding was encouraging, but the scientists did not want to work toward new autoimmune therapies without first analyzing the gene expression patterns and other key epigenetic features of the induced Tregs.  "We wanted to study the entire system at a whole genome level using next generation sequencing technology to better understand the molecular features of these cells," says Yue. Study co-first author Daniela Samaniego-Castruita, a graduate student at LJI, spearheaded the analysis of gene expression and epigenetic changes in the iTregs. A major type of epigenetic modification involves the DNA itself through the addition or removal of molecules called methyl groups from cytosines, one of the four DNA bases. The methyl groups can be further oxidized by TET enzymes. All of these interactions can eventually change how cells "read" the DNA code.  Another type of epigenetic change involves the alteration of DNA accessibility: whether DNA is loosely or tightly coiled. As the DNA coils unwind, regulatory regions become exposed which subsequently influence gene expression. In their analysis, the researchers found TET proteins are absolutely required for maintaining the gene expression and epigenetic features that make Tregs as what they are; and adding Vitamin C led to iTregs with similar similar gene expression and epigenetic features as normal "wild type" Tregs found in the body. The study also reveals an intriguing connection between TET enzymatic activity, Vitamin C and IL-2/STAT5 signaling. "In mice that are deficient for components of IL-2/STAT5 signaling, such as IL-2, IL-2 receptors or STAT5, the Tregs cannot develop properly or they can have impaired function," Yue says. The researchers demonstrate that on one hand, TET-deficiency in Treg cells leads to impaired IL-2/STAT5 signaling; on the other hand, Vitamin C confers iTregs enhanced IL-2/STAT5 signaling by increasing the expression level of IL-2 receptor and the functional form of STAT5, and STAT5 binding to essential regions in the genome, rendering these cells survive better in tough environments with low IL-2 supplementation. "We are looking for more small molecules to stabilize TET activity and generate induced Tregs that are even more stable," says Yue. "These induced Tregs could eventually be used to treat patients." "This research gives us a new way to think about treating autoimmune diseases," says Samaniego-Castruita.       Resveratrol ameliorates high-fat-diet-induced abnormalities in liver glucose metabolism in mice via the AMPK pathway Hebei Medical Institute (China), July 19, 2021 A new study on high fat diet is now available. According to news originating from the Department of Internal Medicine by NewsRx correspondents, research stated, “Diabetes mellitus is highly prevalent worldwide.” Our news reporters obtained a quote from the research from Department of Internal Medicine: “High-fat-diet (HFD) consumption can lead to liver fat accumulation, impair hepatic glycometabolism, and cause insulin resistance and the development of diabetes. Resveratrol has been shown to improve the blood glucose concentration of diabetic mice, but its effect on the abnormal hepatic glycometabolism induced by HFD-feeding and the mechanism involved are unknown. In this study, we determined the effects of resveratrol on the insulin resistance of high-fat-diet-fed mice and a hepatocyte model by measuring serum biochemical indexes, key indicators of glycometabolism, glucose uptake, and glycogen synthesis in hepatocytes. We found that resveratrol treatment significantly ameliorated the HFD-induced abnormalities in glucose metabolism in mice, increased glucose absorption and glycogen synthesis, downregulated protein phosphatase 2A (PP2A) and activated Ca2+/CaM-dependent protein kinase kinase b (CaMKKb), and increased the phosphorylation of AMP-activated protein kinase (AMPK). In insulin-resistant HepG2 cells, the administration of a PP2A activator or CaMKKb inhibitor attenuated the effects of resveratrol, but the administration of an AMPK inhibitor abolished the effects of resveratrol. Resveratrol significantly ameliorates abnormalities in glycometabolism induced by HFD-feeding and increases glucose uptake and glycogen synthesis in hepatocytes.” According to the news editors, the research concluded: “These effects are mediated through the activation of AMPK by PP2A and CaMKKb.”     Hundreds of chemicals, many in consumer products, could increase breast cancer risk List includes potential carcinogens that act by stimulating production of hormones that fuel breast tumors Silent Spring Institute, July 22, 2021 Every day, people are exposed to a variety of synthetic chemicals through the products they use or the food they eat. For many of these chemicals, the health effects are unknown. Now a new study shows that several hundred common chemicals, including pesticides, ingredients in consumer products, food additives, and drinking water contaminants, could increase the risk of breast cancer by causing cells in breast tissue to produce more of the hormones estrogen or progesterone. "The connection between estrogen and progesterone and breast cancer is well established," says co-author Ruthann Rudel, a toxicologist and research director at Silent Spring Institute. "So, we should be extremely cautious about chemicals in products that increase levels of these hormones in the body." For instance, in 2002, when the Women's Health Initiative study found combination hormone replacement therapy to be associated with an increased risk of breast cancer, women stopped taking the drugs and incidence rates went down. "Not surprisingly, one of the most common therapies for treating breast cancer is a class of drugs called aromatase inhibitors that lower levels of estrogen in the body, depriving breast cancer cells of the hormones they need to grow," adds Rudel. To identify these chemical risk factors, Rudel and Silent Spring scientist Bethsaida Cardona combed through data on more than 2000 chemicals generated by the U.S. Environmental Protection Agency (EPA)'s ToxCast program. The goal of ToxCast is to improve the ability of scientists to predict whether a chemical will be harmful or not. The program uses automated chemical screening technologies to expose living cells to chemicals and then examine the different biological changes they cause. Reporting in the journal Environmental Health Perspectives, Rudel and Cardona identified 296 chemicals that were found to increase estradiol (a form of estrogen) or progesterone in cells in the laboratory. Seventy-one chemicals were found to increase levels of both hormones. The chemicals included ingredients in personal care products such as hair dye, chemical flame retardants in building materials and furnishings, and a number of pesticides. The researchers don't yet know how these chemicals are causing cells to produce more hormones. It could be the chemicals are acting as aromatase activators, for instance, which would lead to higher levels of estrogen, says Cardona. "What we do know is that women are exposed to multiple chemicals from multiple sources on a daily basis, and that these exposures add up." The Silent Spring researchers hope this study will be a wakeup call for regulators and manufacturers in how they test chemicals for safety. For instance, current safety tests in animals fail to look at changes in hormone levels in the animal's mammary glands in response to a chemical exposure. And, although high throughput testing in cells has been used to identify chemicals that activate the estrogen receptor, mimicking estrogen, the testing has not been used to identify chemicals that increase estrogen or progesterone synthesis. "This study shows that a number of chemicals currently in use have the ability to manipulate hormones known to adversely affect breast cancer risk," says Dr. Sue Fenton, associate editor for the study and an expert in mammary gland development at the National Institute of Environmental Health Sciences. "Especially concerning is the number of chemicals that alter progesterone, the potential bad actor in hormone replacement therapy. Chemicals that elevate progesterone levels in the breast should be minimized." The researchers outlined a number of recommendations in their study for improving chemical safety testing to help identify potential breast carcinogens before they end up in products, and suggest finding ways to reduce people's exposures, particularly during critical periods of development, such as during puberty or pregnancy when the breast undergoes important changes. The project is part of Silent Spring Institute's Safer Chemicals Program which is developing new cost-effective ways of screening chemicals for their effects on the breast. Knowledge generated by this effort will help government agencies regulate chemicals more effectively and assist companies in developing safer products.     Antioxidant activity of limonene counteracts neurotoxicity triggered by amyloid beta 1-42 oligomers in cortical neurons University of Naples (Italy), July 19, 2021 According to news reporting from Naples, Italy, by NewsRx journalists, research stated, “Many natural-derived compounds, including the essential oils from plants, are investigated to find new potential protective agents in several neurodegenerative disorders such as Alzheimer's disease (AD).” The news editors obtained a quote from the research from School of Medicine: “In the present study, we tested the neuroprotective effect of limonene, one of the main components of the genus * * Citrus* * , against the neurotoxicity elicited by Ab [ [1-42] ] oligomers, currently considered a triggering factor in AD. To this aim, we assessed the acetylcholinesterase activity by Ellman's colorimetric method, the mitochondrial dehydrogenase activity by MTT assay, the nuclear morphology by Hoechst 33258, the generation of reactive oxygen species (ROS) by DCFH-DA fluorescent dye, and the electrophysiological activity of K [ [V] ] 3.4 potassium channel subunits by patch-clamp electrophysiology. Interestingly, the monoterpene limonene showed a specific activity against acetylcholinesterase with an IC [ [50] ] almost comparable to that of galantamine, used as positive control. Moreover, at the concentration of 10 g/mL, limonene counteracted the increase of ROS production triggered by Ab [ [1-42] ] oligomers, thus preventing the upregulation of K [ [V] ] 3.4 activity. This, in turn, prevented cell death in primary cortical neurons, showing an interesting neuroprotective profile against Ab [ [1-42] ] -induced toxicity.” According to the news editors, the research concluded: “Collectively, the present results showed that the antioxidant properties of the main component of the genus * * Citrus* * , limonene, may be useful to prevent neuronal suffering induced by Ab [ [1-42] ] oligomers preventing the hyperactivity of K [ [V] ] 3.4.”     Meditation And Yoga Change Your DNA To Reverse Effects Of Stress, Study Shows Coventry University (UK), July 22, 2021 Many people participate in practices such as meditation and yoga because they help us relax. At least those are the immediate effects we feel. But much more is happening on a molecular level, reveal researchers out of Coventry University in England. Published in the journal Frontiers in Immunology, this new research examined 18 studies on mind-body interventions (MBIs). These include practices such as mindfulness meditation and yoga. Comprehensively, these studies encompassed 846 participants over 11 years. The new analysis reveals that MBIs result in molecular changes in the human body. Furthermore, researchers claim that these changes are beneficial to our mental and physical health. Body's Response to Stress Causes Damage To elaborate, consider the effect that stress has on the body. When we are under stress, the body increases the production of proteins that cause cell inflammation. This is the natural effect of the body's fight-or-flight response. It is widely believed that inflammation in the body leads to numerous illnesses, including cancer. Moreover, scientists also deduct that a persistent inflammation is more likely to cause psychiatric problems. Unfortunately, many people suffer from persistent stress, therefore they suffer from pro-inflammatory gene expression. But there is good news! According to this new analysis out of Coventry, people that practice MBIs such as meditation and yoga can reverse pro-inflammatory gene expression. This results in a reduced risk of inflammation-related diseases and mental conditions. Lead investigator Ivana Buric from Coventry University's Centre for Psychology, Behaviour and Achievement stated: Millions of people around the world already enjoy the health benefits of mind-body interventions like yoga or meditation, but what they perhaps don't realise is that these benefits begin at a molecular level and can change the way our genetic code goes about its business. These activities are leaving what we call a molecular signature in our cells, which reverses the effect that stress or anxiety would have on the body by changing how our genes are expressed. Put simply, MBIs cause the brain to steer our DNA processes along a path which improves our wellbeing. More needs to be done to understand these effects in greater depth, for example how they compare with other healthy interventions like exercise or nutrition. But this is an important foundation to build on to help future researchers explore the benefits of increasingly popular mind-body activities.               Large-scale study finds greater sedentary hours increases risk of obstructive sleep apnea Study finds that maintaining an active lifestyle can reduce the risk of OSA, encourages physicians to recommend exercise-based interventions for those at risk Brigham and Women's Hospital, July 22, 2021 A new study by investigators from Brigham and Women's Hospital examined the relationship between active lifestyles and the risk of obstructive sleep apnea (OSA). The study followed around 130,000 men and women in the United States over a follow-up period of 10-to-18 years and found that higher levels of physical activity and lower levels of sedentary behavior were associated with a lower risk of OSA. Their results are published in the European Respiratory Journal.  "In our study, higher levels of physical activity and fewer hours of TV watching, and sitting either at work or away from home were associated with lower OSA incidence after accounting for potential confounders," said Tianyi Huang, MSc, ScD, an Associate Epidemiologist at the Brigham. "Our results suggest that promoting an active lifestyle may have substantial benefits for both prevention and treatment of OSA."  OSA is a type of sleep apnea in which some muscles relax during sleep, causing an airflow blockage. Severe OSA increases the risk of various heart issues, including abnormal heart rhythms and heart failure.  Using the Nurses' Health Study (NHS), Nurses' Health Study II (NHSII) and Health Professionals Follow-Up Study (HPFS), the research team used statistical modeling to compare physical activity and sedentary hours with diagnoses of OSA. Both moderate and vigorous physical activity were examined separately and both were strongly correlated with lower risk of OSA, showing no appreciable differences in the intensity of activity. Moreover, stronger associations were found for women, adults over the age of 65 and those with a BMI greater than or equal to 25 kg/m2.  "Most prior observational studies on the associations of physical activity and sedentary behavior with OSA were cross-sectional, with incomplete exposure assessment and inadequate control for confounding," said Huang. "This is the first prospective study that simultaneously evaluates physical activity and sedentary behavior in relation to OSA risk."  This study also differs from others because of its large sample size and detailed assessment pf physical activity and sedentary behaviors. The research team was able to take many associated factors into account, making the findings more credible.  The authors note that all collected data, both of OSA diagnosis and physical activity or sedentary behavior, were self-reported. While all study participants were health professionals, mild OSA is often difficult to detect and can remain clinically unrecognized. Furthermore, only recreational physical activity was taken into consideration, leaving out any physical activity in occupational settings. Sedentary behavior was only counted as sitting while watching TV and sitting away from home or at work.  According to Huang, the next research steps would be to collect data using actigraphy, home sleep apnea tests and polysomnography, rather than self-reports.  In light of the findings, investigators encourage physicians to highlight the benefits of physical activity to lower OSA risk.  "We found that physical activity and sedentary behavior are independently associated with OSA risk," said Huang. "That is, for people who spend long hours sitting every day, increasing physical activity in their leisure time can equally lower OSA risk. Similarly, for those who are not able to participate in a lot of physical activity due to physical restrictions, reducing sedentary hours by standing or doing some mild activities could also lower OSA risk. However, those who can lower sedentary time and increase physical activity would have the lowest risk."

Did you know that there are at least 4,700 highly fluorinated chemicals, often called “PFAS” in many everyday consumer products, and that these chemicals pose harm to human health? Join Food Sleuth Radio host and registered dietitian, Melinda Hemmelgarn, for her interview with Laurel Schaider, Ph.D., Research Scientist at the Silent Spring Institute. Schaider discusses water contamination from PFAS chemicals, and the consumer products that contain them, including: non-stick cookware, grease-proof food packaging, and even dental floss.

Cheryl Osimo Executive Director of the Massachusetts Breast Cancer Coalition talks with Emmy Winner Charlotte Robinson host of OUTTAKE VOICES™ about their 22nd premier annual fundraising event the "Lesbians and Friends LGBTQ Dance Party For Prevention" that takes place at The Inn at Brookline at 1200 Beacon Street in Brookline, Massachusetts on October 26th from 8P to 12P. This year MBCC is proud to be honoring Massachusetts Attorney General Maura Healey. Osimo stated, "Attorney General Healey has worked tirelessly for the citizens of Massachusetts across so many important issues. We admire all that she has accomplished and continues to work towards on behalf of her constituents and look forward to honoring her at this year’s event." AG Healey will not be present at the event but will be appearing in a special video presentation to be shown during the evening’s festivities. MBCC will also be recognizing longtime MBCC supporter Laura Diamond owner of Diamond Physical Therapy Associates and Moving Violations Motorcycle Club the oldest women’s motorcycle club in New England. In Massachusetts breast cancer incidence rates are 12% higher than the national average which estimates that 1 in 8 U.S. women will develop breast cancer in her lifetime. However the most commonly cited risk factors, genetic inheritance and lifestyle factors, are present in only 20-30% of breast cancer cases. This leaves 70-80% of cases unexplained. MBCC is the only breast cancer non-profit working closely with a research and sister organization Silent Spring Institute to investigate preventable environmental causes of the disease. This work is funded through annual fundraising events like the upcoming Lesbians & Friends Dance: A Party for Prevention.

The full broadcast of Boston Public Radio from Friday, February 15th, 2019. Amid financial setbacks, General Electric decided to scale back its plans for a headquarters by selling its Seaport District property and doing away with most of the jobs that would come with it. Did Massachusetts get duped? Or is it a win that the state will be reimbursed the $87 million of tax incentives we gave them to move to Boston? Shirley Leung, the Boston Globe’s interim editorial page editor and a WGBH contributor, joined us for that and more. Then, on top of GE pulling out of Boston, Amazon bailed on New York, rescinding its plans to develop another headquarters in Long Island City, Queens. We opened the lines to ask you, is it time we bail out on corporate America? As she does every Friday, Emily Rooney joined us for her famous list of fixations and fulminations, and more. Rooney is the host of Beat The Press on WGBH and a Boston Public Radio contributor. We review the latest headlines at the intersection of tech, policy and commerce with tech writer, podcaster and blogger Andy Ihnatko. You can follow him on Twitter @Ihnatko. Detox products have become a staple in the health and wellness industry. There are detox teas, detox massages and detox gut cleanses … but do we know what we’re actually detoxifying ourselves of? And where these toxins are coming from? Researchers at the Silent Spring Institute have developed a test that detects the presence of 10 of the most common household chemicals that can accumulate in our bodies. This is all part of a scientific study to get a better sense of our collective exposure to environmental chemicals. Joining us to talk about the study are Ruthann Rudel, director of research at Silent Spring Institute, and Dr. Cathie Ragovin, a psychiatrist, co-founder of the Silent Spring Institute and co-chair of its Board of Directors. A sporting goods store goes bust for refusing to sell Nike products because of the Colin Kaepernick connection. Callie Crossley, the host of Under The Radar on WGBH, joins us for that and more. And finally, it’s time for our Friday News Quiz with Kyle Amato and Corey Purcell, the guys behind the Ethan Hawke-obsessed podcast, "The Hawke Cast," dedicated to the films of Ethan Hawke.

About Julia Brody: Dr. Julia Brody and her team at the Silent Spring Institute in Massachusetts are well-known pioneers in exploring linkages between toxic chemicals exposures and breast cancer, prompted by the high incidence of breast cancer in Cape Cod. Upholding the legacy of Rachel Carson in exploring how environmental threats contribute to disease incidence, Brody has produced compelling results from her work in Cape Cod. Recent work has brought her team to Richmond and Bolinas where the team as tested a number of homes for the presence of toxic chemicals in indoor and outdoor air. Householders in both towns found the results surprising. Like most people, they assumed that exposures to toxicants occurred primarily if one were to live near an industrial area, a military facility or near the site of some sort of chemical accident.

Join Michael Lerner in a conversation with Julia about her research, which indicates that many of us may be additionally exposed to toxicants through the use of products we use everyday, products such as cleaners, personal care products, paints, solvents, or the materials we use in constructing our houses. Julia Brody, PhD Julia, executive director of Silent Spring Institute, is a leader in research on breast cancer and the environment and in community-based research and public engagement in science. Brody’s current research focuses on methods for reporting to people on their own exposures to hormone disruptors and other emerging contaminants when the health effects are uncertain.
