A Rewired Metabolism Links the Aging Epigenome to Vision LossMay 16, 2020They say hindsight is 20/20, but for those of us looking over at a lifetime of memories, things might seem a little blurrier through our aging eyes. That’s because, unlike the fine wines, delectable whiskies, and smelly cheeses that we love to catabolize, the human epigenome tends not to age very well and a wide […]
Not Aging Gracefully? Two Epigenetic Regulators May be to BlameMarch 16, 2020In the last 50 years, there has been a ~20% increase in global life expectancy but interestingly, there has not been a corresponding increase in the number of healthy years lived. Lubin Jiang and Shi-Qing Cai at the Chinese Academy of Sciences (Shanghai, China) sought to understand that disparity by examining the genetic factors involved […]
Single Cell Analyses Reveal How Epigenetic Drift Makes Stem Cells Age Badly!October 28, 2019While cheese and wine (and whisky!) all get better with age, the human body fares less well! Although partaking in too many culinary delights hardly helps, studies have established the reduced number and activity of stem cells as a cause for the age-related deterioration of various tissue types. With this in mind, a talented team […]
Foretelling Future Hippocampal Transcription and Disease Risk with Early DNA Methylation ProfilesOctober 27, 2019Will it rain tomorrow? Will I ever win the lottery? Will our new paper finally be accepted!? Unfortunately, we have yet to come up with a sturdy means to predict our fates far in the future; however, new research by Hadad and colleagues now suggests that DNA methylation profiles in young cells accurately foretell changes […]
Webinar: The Epigenetics of the Exposome and Aging – Paul G. ShielsOctober 2, 2019Don’t miss this great webinar detailing some of the latest discoveries about the role of epigenetics in aging. Aging results in a gradual and progressive loss of physiological functions and physical abilities over time. Overcoming the growing burden of age-related issues is one of the greatest challenges facing modern society. These issues are leading to […]
Mutant DNMT3A Underperforms in Overgrowth SyndromeJune 25, 2019If you’re underperforming at work, you might end up with a rejected paper, failed experiments, or an angry boss. However, this isn’t so bad when compared to how mutated DNMT3A underperforms in its role as a DNA methyltransferase, since that can result in a pathogenic overgrowth known as Tatton-Brown-Rahman syndrome (TBRS). Despite DNMT3A’s known role […]
Enhancer Hypomethylation in Alzheimer’s Disease Brain Paves the Way for Cell DeathJune 15, 2019When it comes to understanding the epigenetics of aging, Alzheimer’s Disease (AD) has enhanced our knowledge in countless ways. This neurodegenerative disease has taught us to embrace healthy aging, and some surprising players have emerged from the examination of DNA methylation. Studies have uncovered a role for enhancers in AD; however, investigations into the consequences of DNA methylation at these […]
New Epigenetic Clock Offers an Evolutionary Conserved View of Aging Through Ribosomal DNA MethylationApril 27, 2019With updates and novel iterations to the “epigenetic clock” occurring at a pace faster than our smartwatches, it’s about time a new player emerged in the world of epigenetic clocks. Not only can these specialist timepieces keep track of our chronological age, but they can also tell us how environmental factors affect the pace of […]
Reactivating “Fossil” Enhancers from Embryonic Development in Adult TissuesApril 10, 2019The Jurassic Park movies got the whole world excited about resurrecting dinosaurs from fossilized DNA, but more recent findings that the half-life of DNA is only 521 years mean that dream is science fiction. So, while the finer details of dinosaur genomes may be lost in the fossil record, new work has dug up epigenomic […]
Inflammation in the Information Age: Multi-Tissue Chromatin and Transcriptional States of Mammalian AgingMarch 26, 2019We’re living in the information age―the age of supercomputers, big data, and machine learning―and the epigenetics field is capitalizing on these capabilities. New research from the lab of Anne Brunet at Stanford University harnesses the power of the ‘information age’ to provide insight on the ‘inflammation age’―that is, changes in the epigenetic landscape that lead […]
