title: Effect of centchroman and tamoxifen on protein patterns of fallopian tubes of rhesus monkeys, Macaca mulatta.
abstract: To study the effect of centchroman and tamoxifen on estrogen-dependent proteins of fallopian tubes of rhesus monkey, these antiestrogens were given with and without estradiol to ovariectomized monkeys. In absence of estradiol, both the compounds induced the synthesis of 130 and 95 K proteins. Concentration of 85 K protein was also increased markedly. These compounds, however, suppressed the estrogen stimulated synthesis of 130 K protein when administered with estradiol. The results show that both centchroman and tamoxifen possess estrogen agonistic as well as antagonistic properties and 130 K protein can be used as a marker protein to study estrogen action and for screening of antiestrogenic compounds in a primate model.
