Epigenetics and Pregnancy: Conditional Snapshot or Rolling Event

Int J Mol Sci. 2022 Oct 21;23(20):12698. doi: 10.3390/ijms232012698.

Abstract

Epigenetics modification such as DNA methylation can affect maternal health during the gestation period. Furthermore, pregnancy can drive a range of physiological and molecular changes that have the potential to contribute to pathological conditions. Pregnancy-related risk factors include multiple environmental, behavioral, and hereditary factors that can impact maternal DNA methylation with long-lasting consequences. Identification of the epigenetic patterns linked to poor pregnancy outcomes is crucial since changes in DNA methylation patterns can have long-term effects. In this review, we provide an overview of the epigenetic changes that influence pregnancy-related molecular programming such as gestational diabetes, immune response, and pre-eclampsia, in an effort to close the gap in current understanding regarding interactions between the environment, the genetics of the fetus, and the pregnant woman.

Keywords: DNA methylation; epigenetics modification; inheritance; maternal stress; pre-eclampsia; pregnancy.
