title: High acyl-CoA cholesterol acyl transferase activity in fetal rabbit aorta: evidence for the presence of stimulating factor(s) in amniotic fluid.
abstract: The activity of Acyl CoA-cholesterol acyl transferase was markedly high in fetal aortas when compared to maternal and adult male rabbits. This activity dropped by 50% at 1 week of age. This high activity in fetal aorta a) did not appear to be due to changes in plasma cholesterol levels or to the later development of endogenous inhibitor in the aorta, but rather b) due to stimulatory factor(s) present in amniotic fluid.
