title: Role of the liver for the receptor-mediated catabolism of low-density lipoprotein in the 17 alpha-ethinylestradiol-treated rat.
abstract: Effects of ethinylestradiol on LDL catabolism and plasma cholesterol were studied in the rat. Hormone treatment led to a reduction in plasma cholesterol and to an increased receptor-mediated catabolism of LDL in the liver and the adrenals. The liver was the most important organ accounting for more than 95% of the receptor-mediated tissue accumulation of LDL following estrogen treatment. It is concluded that the reduction in plasma cholesterol during treatment with ethinylestradiol is due to the stimulation of LDL receptors in the liver.
