摘要

Epigenetics investigates heritable changes in gene expression that occur without changes in DNA sequence.Several epigenetic mechanisms,including DNA methylation and histone modifications,can change genome function under exogenous influence.Results obtained from animal models indicate that in utero or early-life environmental exposures produce effects that can be inherited transgenerationally and are accompanied by epigenetic alterations.The search for human equivalents of the epigenetic mechanisms identified in animal models is in progress.
