Estrogen Receptor in the Mammalian Liver

Abstract

The cytosol from livers of adult female mammals contains [3H]estradiol-binding proteins that can translocate to the nucleus and attach to chromatin. In comparison to the prepubescent rat, adults have higher estrogen binding in the liver and greater increases in plasma renin substrate after administration of estrogen. The protein in the liver which binds estrogen may be an estrogen receptor involved in modulating hepatic synthesis of selective plasma proteins.
