Inhibition of mechanistic target of rapamycin signaling decreases levels of O-GlcNAc transferase and increases serotonin release in the human placenta

Changes in placental function, in particular down-regulation of placental O-linked N-acetylglucosamine (O-GlcNAc) transferase (OGT) in response to maternal stress and increased placental secretion of serotonin into the fetal circulation following maternal infection, have been mechanistically linked to adverse neurodevelopment in mice. We hypothesized that mechanistic target of rapamycin (mTOR) signaling is a key regulator of trophoblast...
