The largest twin study on epigenetic profiles yet reveals the extent to which lifestyle and age can impact gene expression, an international research team reports in this week's PNAS. Senior author ...

For twins as close as the Mitchells, living in sync seems to come naturally. Photograph by Jodi Cobb Feinberg's study focuses on a particular epigenetic process called DNA methylation, which is ...

Gavrilets and a pair of colleagues proposed the idea of epigenetics influencing sexual orientation several ... and their colleagues scanned through the genomes of 47 male twin pairs. In 37 pairs, one ...

Epigenetic silencing is one way to turn genes off, and it can contribute to differential expression. Silencing might also explain, in part, why genetic twins are not phenotypically identical.

The best example is the differential phenotypic presentation of older monozygotic twins (10). Epigenetics is a science of heritable biologic adaptation, a concept that will become evident in the ...

For instance, in monozygotic twins, epigenetic profiles become increasingly dissimilar with age despite identical genetic backgrounds. 5 Similarly, interventions such as calorie restriction that ...

Optimal technology for epidemiologically-based epigenetic studies and longitudinal samples of 100 stringently characterised discordant MZ twins for exposure to psychosocial stress during adolescence ...
