Epigenetics, the dynamic regulation of genetic expression, involves complex molecular mechanisms. While the process of gene silencing by methylating the H3K27 position in histones is understood, not ...

Scientists at Harvard Medical School have investigated why we age, and identified a possible way to reverse it. In tests in mice, the team showed that epigenetic “software glitches” drive the symptoms ...

Discover how emerging epigenetic clock models are reshaping our understanding of ovarian aging and revealing both the promise and current limits of predicting fertility outcomes through biological age ...

All the cells in an organism have the exact same genetic sequence. What differs across cell types is their epigenetics—meticulously placed chemical tags that influence which genes are expressed in ...
