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 […]
