Abstract/OtherAbstract:
Hypercholesterolemia occurs during pregnancy in rats and human beings, beginning in the second trimester and increasing progressively throughout the remainder of pregnancy. The present study quantified de novo cholesterol synthesis in vivo and in vitro in pregnant animals using 3H2O as the substrate for measuring cholesterogenesis. In the third trimester, cholesterol synthesis by pregnant rat gut and carcass (all tissues not specifically studied) was not significantly different from that observed in controls. However, hepatic cholesterol synthesis was markedly stimulated in third trimester pregnant rats. Additionally, cholesterol synthesis in the placenta and fetus occurred at a very substantial rate. The magnitude of placental cholesterol synthesis was similar to that observed in the liver of control animals whereas fetal cholesterogenesis was considerably greater. Cholesterol feeding greatly suppressed hepatic cholesterol synthesis in both control and pregnant animals, so that the difference between control and pregnant animals was obliterated. Cholesterol feeding did not significantly affect the accumulation of newly synthesized cholesterol in either the placenta or fetus. In the Saguines fusciollis monkey, pregnancy similarly stimulated hepatic cholesterol synthesis, and the fetus and placenta were important sites of in vivo de novo cholesterogenesis.
