Pregnancy Epigenetically Ages Mothers – But Breastfeeding May Reverse ItApril 22, 2024Our mothers might be onto something when they jokingly blame us for their gray hair and wrinkles. In two recent studies, DNA methylation-based epigenetic clocks show that pregnancy, with its far-ranging emotional and physical changes, increases the biological ages of mothers. On the bright side, the effects were reversible in those who breastfed, according to […]
Updated cfDNA Nucleosomics Technology Upgrades our Epigenetic ClocksMarch 4, 2024A new style, novel functionalities, and a better overall product; we always want our smartwatches to employ the latest technology, and why not?! Now, a well-timed update involving cell-free DNA (cfDNA) nucleosomics-based technology provides for a significantly upgraded epigenetic clock, which may boost aging-based research. A punctual team led by Vladimir B. Teif (University of […]
TIME-Seq Flies When Constructing Cost-Effective Epigenetic ClocksFebruary 19, 2024If time drags and money disappears when looking at DNA methylation-based epigenetic clocks, you are “in time” to hear of a newly described efficient and cost-effective bisulfite sequencing approach! Time flies – but money does not – with “tagmentation-based indexing for methylation sequencing” or TIME-seq! An on-time team led by David A. Sinclair (Harvard Medical […]
An Evolutionary and Epigenetic Tour-de-force Links DNA Methylation and Mammalian AgingSeptember 11, 2023Have you climbed Mount Everest? Recorded a critically acclaimed album?? Written the great American novel??? These life-affirming feats of body and mind pale into insignificance when compared to the evolutionary and epigenetic tour-de-force reported in two recent papers based on mammalian DNA methylation datasets of colossal size and importance. An expeditionary force led by Steve […]
Bringing in “Young Blood” Persistently and Systemically Slows Epigenetic AgingAugust 22, 2023Be it a football team, a book club, or an epigenetics lab, bringing in “young blood” can seriously improve quality in the short term, but does this effect endure? Now, a heterochronic parabiosis study reveals that long-term exposure to young blood induces persistent slowing of DNA methylation-based epigenetic aging and extends healthy lifespans in mice! […]
Altered Chromatin Accessibility Shows Why Aging Stem Cells Don’t Know if They’re Coming or Going!August 13, 2023Once young and carefree, the passing years creep up on us all and bring so many responsibilities and places to be that we don’t know whether we are coming or going! A busy new study shows that the chromatin accessibility and gene expression alterations that occur during aging impact neural stem cells (NSCs) in much […]
Move Over Caloric Restriction – Hungry-Hungry Histones Slow Aging!May 30, 2023Kick the kebab, bin the burger, axe the avocado toast?! While caloric restriction represents a hunger-inducing yet effective means to extend lifespans, a tasty new study highlights how “hungry-hungry histones” create a neural hunger “state” that slows aging (even when getting our fill), suggesting that growing old may be more delicious than we think! While […]
Tissue Regeneration Rejuvenates Chromatin Age-Domains to Wake Cells from Hyper-quiescenceMay 22, 2023Taking a break from the hectic world now and again might just save your sanity; however, we sometimes need a push to get back up the pace of everyday life! Now, exciting new tissue rejuvenation-based research into the chromatin age-domains associated with hyper-quiescence suggests that aging cells also suffer from this pesky problem. Aging tissues […]
eBook: Epigenetics of Cancer & Disease RiskMay 3, 2023The application of epigenetic approaches to disease research is moving quickly and hundreds of new papers are published every year, from virology to neurobiology and cancer. In this eBook, we present short summaries of interesting discoveries that caught our attention in each of these areas. Table of Contents Chapter 1: Epigenetics in Disease Risk Taking […]
mRNA Shows Its Age and Quiets Down the Immune System with Cap2 MethylationFebruary 14, 2023Wrinkles, gray hair, … Cap2 methylation on mRNA? It turns out that these are all signs of aging. Two elegant new methods to show that Cap1 gets slowly modified to Cap2 as mRNAs age. And just like boomers, they want to live the quiet life, calming down the innate immune system to prevent autoimmunity. Although […]
