Transgenerational metabolic outcomes associated with uteroplacental insufficiency

Abstract

Intrauterine growth restriction increases adult metabolic disease risk with evidence to suggest that suboptimal conditions in utero can have transgenerational effects. We determined whether impaired glucose tolerance, reduced insulin secretion, and pancreatic deficits are evident in second-generation (F2) male and female offspring from growth-restrictedmothers, in a rat model of uteroplacental insufficiency. Late gestation uteroplacental insufficiency was induced by bilateral uterine vessel ligation (restricted) or sham surgery (control) in Wistar-Kyoto rats. First-generation (F1) controland restricted females were mated with normal males and F2 offspring studied at postnatal day 35 and at 6..
