Epigenetics is a rapidly growing field of study that focuses on the heritable changes in gene expression that occur without alterations to the underlying DNA sequence. These changes are caused by ...

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 ...

Social stress can affect the way genes are expressed. A new study has found that epigenetic effects could explain why some people who experience trauma in childhood have an increase in the risk of ...

Researchers assessed DNA methylation at 800,000 sites in the genome in blood samples collected from 900 people. The study includes extensive clinical information on participants, who all provided ...

Epigenetic clocks provide a molecular framework for assessing biological ovarian age by integrating DNA methylation patterns with hallmarks of reproductive aging. While these clocks show moderate ...

When we think about genetic inheritance, we usually leap to DNA, the four-letter code containing the instructions for building a living organism. Scientists know that DNA encodes everything from hair ...

New research in C. elegans from scientists at Howard Hughes Medical Institute (HHMI) helps explain how changes in the parents’ lysosomes that promote longevity are transferred to their offspring.

The COVID-19 pandemic gave us tremendous perspective on how wildly symptoms and outcomes can vary between patients experiencing the same infection. How can two people infected by the same pathogen ...

Epigenetic variation, like genetic variation, can be inherited and influence traits across generations. However, epigenetic variation does not involve changes to the genetic sequence that makes up DNA ...
