In the Nature publication Signal Transduction and Targeted Therapy, researchers have described how glibenclamide, a drug used to treat type 2 diabetes, partially reverses epigenetic alterations and fights cellular senescence in mice. A system tightly tied together This paper begins with a discussion of the relationship between epigenetic alterations and cellular senescence. The histone H3K4me3...

A new paper published in Nature Aging suggests that somatic mutations cause significant remodeling of the epigenetic landscape. The findings might be relevant to future anti-aging interventions [1]. The genome and the epigenome Genomic instability and epigenetic alterations are two of the hallmarks of aging [2]. The former occurs in somatic cells due to replication...

A recent investigation into Hungarian Olympic champions suggests slower epigenetic aging and differences in gene methylation patterns between champions and non-champions [1]. Exercising your way to longevity Exercise seems to be the best lifestyle factor to slow aging and alleviates many aging-associated diseases and molecular changes. We have previously reported that exercise positively impacts cognition...

Today, we bring you a selection of presentations from the annual conference organized by the Gerontological Society of America. Most of our savvy readers, if asked to name the biggest gerontology conference, would probably go with the venerable ARDD in Copenhagen or the new favorite, Hevolution Foundation’s Healthspan Summit in Riyadh. Yet, both pale in...

Researchers have reported in Aging Cell that injecting specific one-carbon metabolites into the hippocampus can rejuvenate its cells. A small molecule approach Why We Age: Epigenetic AlterationsEpigenetic alterations are age-related changes in gene expression that harm the fundamental functions of cells and increase the risk of cancer and other age-related diseases. One of the proposed...

Juan José Alba-Linares and his research team have published a preprint study that examined why different animals age at different rates. They found that epigenetic changes over time could explain why some animals live longer and estimated an upper limit for mammalian lifespan [1]. A problem of noise Why We Age: Epigenetic AlterationsEpigenetic alterations are...
