Diet-induced obesity in mice reduces placental efficiency and inhibits placental mTOR signaling

Abstract excerpt

As in humans, obesity during pregnancy in mice results in elevated maternal insulin levels and metabolic programming of offspring. mTOR signaling regulates amino acid transport and may function as a placental nutrient sensor. Because obesity is a condition with increased nutrient availability, we hypothesized that diet-induced obesity activates placental mTOR signaling. To test this hypothesis, female C57BL/6J...
