Maternal obesity alters fetal liver metabolism via placental molecular signals

https://www.news-medical.net/news/20260826/Maternal-obesity-alters-fetal-liver-metabolism-via-placental-molecular-signals.aspx A mother's obesity during pregnancy may send molecular signals across the placenta that permanently alter her son's liver metabolism, according to a new study in mice published in Nature Communications. The research traces this effect to a maternal sEV–miRNA–epigenetic axis that links fetal liver programming to long-term metabolic health.
