Treatment of ovariectomized rats with dietary clofibrate caused a manyfold
increase in the liver microsomal esterification of estradiol with fatty aci
ds. The stimulatory effect of clofibrate administration on fatty acid ester
ification of estradiol by liver microsomes was paralleled in vivo by enhanc
ed estradiol-induced increases in the formation of lobules in the mammary g
land and by increased incorporation of bromodeoxyuridine into these lobules
. In contrast to the stimulatory effect of clofibrate administration on the
action of estradiol in the mammary gland, clofibrate administration had no
effect on the uterotropic action of estradiol. These results indicate that
clofibrate administration has a selective stimulatory effect on the hormon
al action of estradiol in the mammary gland but not in the uterus.
