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 ...

About 12% of pregnancies begin as multiples, but fewer than 2% reach full term. Vanishing Twin Syndrome occurs when one ...

These can be things like nutrition, temperature, exposures to toxins, and position in the womb, and they can cause small differences in twins both before or after birth. Epigenetics don't change ...

Why do identical twins sometimes experience different health ... Just how much does our environment shape us? The answer is epigenetics, the complex interplay between genes inherited from parents ...

Molecular biologist Arturas Petronis and his colleagues at the Center for Addiction and Mental Health in Toronto, Canada compared DNA methylation patterns from epithelial cells inside the mouths of 39 ...

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 ...

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.
