CpGT and MethylGPT – Large AI Models Lay the Foundation for Advanced DNA Methylation AnalysisNovember 27, 2024Vast amounts of DNA methylation data have paved the way for epigenetic clocks to significantly advance aging research; however, generative artificial intelligence (AI) may have now laid the foundation for more transformative insights into DNA methylation. Two preprints report the application of transformer architecture to develop “foundation” or large AI models trained on vast DNA […]
Children Prenatally Exposed to Cannabis Have Altered DNA MethylationOctober 7, 2024As more states legalize and decriminalize cannabis, more questions are being raised about its effects, especially on pregnancy. Now, a clear-thinking team sees through the haze and shows that maternal cannabis use during pregnancy is associated with epigenome-wide differential DNA methylation in the blood of exposed children, especially in genes involved in neurodevelopment. Studies have shown […]
Metformin Keeps Aging Primate Epigenomes “In Form”September 30, 2024Those of us feeling the all too familiar effects of time may look to cut back on certain “excesses” and keep fit (in both body and mind) to maintain a healthy aging process. Now, a team of fitness enthusiasts has revealed that long-term treatment with the diabetes drug metformin maintains an aging population of monkeys […]
scEpiAge Brings Single-cell Resolution to Epigenetic Clock HeterogeneitySeptember 23, 2024DNA methylation-based epigenetic clock construction has generally relied on bulk datasets representing findings from thousands or millions of cells, and now, a new single-cell epigenetic clock age predictor known as scEpiAge may help to resolve the impact of heterogeneity. Can improved resolution offer more profound insight into the aging process? A team led by Marc […]
Keeping up With Epigenetic Clocks: PRC2-AgeIndex Measures Gains of DNA Methylation Across the GenomeAugust 6, 2024While it may seem like it’s harder to keep up with epigenetic clocks than with the Kardashians, this is one you’re not going to want to miss. Many epigenetic clocks people use to assess aging are built on the DNA methylation status of a few CpGs, and it’s unclear how these sites are related to […]
The Epigenetics of Exercise: Acvr1c Improves Learning and MemoryJuly 24, 2024Exercise can boost your mood and improve heart and bone health. Now, a talented team uncovers the epigenetic mechanisms behind another good reason to hit the gym. Working out can help with learning and long-term memory via Acvr1c, a member of the TGF-beta family. Gym rats—er, exercising mice—can learn under “subthreshold training” conditions after a workout, […]
Age-related Chromatin Remodeling: Loss of Epigenetic Info or the Hijacking of Maturation?July 22, 2024In this world nothing can be said to be certain, except Spain winning at football and age-related chromatin remodeling! While this remodeling was thought to drive aging via the loss of epigenetic information, new research provides evidence for the “hijacking” of developmental maturation via activator protein 1 (AP-1)-activity as a major player. Surefire researchers “captained” […]
Attacking Aging with TAC: A TERT Activator CompoundJuly 8, 2024Aching joints and wrinkled skin are an unwelcome part of aging, but in the future, you might be able to avoid arthritis medications and cosmetic procedures by getting a shot of TERT activator compound (TAC). A young-at-heart team identified this small molecule, which increases transcription of a telomerase subunit called TERT. The upshot is that […]
cfDNA Methylation Analysis Captures the Double Trouble of Inflammaging!July 1, 2024Analyzing cell-free (cf)DNA methylation from liquid biopsies represents a non-invasive approach to profile various diseases, but what if it could help us understand the devious duo of inflammaging – aging and inflammation? A talented team has dealt with this “double trouble” by applying enzymatic methyl-seq (EM-seq) to evaluate cfDNA methylation patterns. Researchers headed by Jian-Ping […]
DNA Methylation Differences in Imprinting Control Regions Contribute to Ethnic Disparities in Alzheimer’s Disease RiskMay 28, 2024Non-Hispanic Black (NHB) patients have a two-fold higher risk of developing Alzheimer’s disease than non-Hispanic White (NHW) patients for unknown reasons; now, a fascinating epigenetics study reveals the involvement of DNA methylation at imprinting control regions (ICRs). Researchers headed by Randy L. Jirtle and Cathrine Hoyo (North Carolina State University) explored ethnic variation in disease […]
