An epigenetic difference in twins explains different risk of breast cancer
Monozygotic twins have the same genome, that is, the same DNA molecule in both siblings. Despite being genetically identical, both twins may have different diseases at different times. This phenomenon is ...

Evidence of biological process that embeds social experience in DNA that affects entire networks of genes
(Medical Xpress)—Early life experience results in a broad change in the way our DNA is "epigenetically" chemically marked in the brain by a coat of small chemicals called methyl groups, according to researchers at McGill ...

In cancer, an embryonic gene-silencing mechanism gone awry
There are some genes that are only activated in the very first days of an embryo's existence. Once they have accomplished their task, they are shut down forever, unlike most of our genes, which remain active throughout our ...
