Description:
Partially purified lipid extracts of Saccharomyces cerevisiae contain a substance that displaces tritiated estradiol from rat uterine cytosol estrogen receptors. The yeast product induces estrogenic bioresponses in mammalian systems as measured by induction of progesterone receptors in cultured MCF-7 human breast cancer cells and by a uterotrophic response and progesterone receptor induction after administration to ovariectomized mice. The findings raise the possibility that bakers' yeast may be a source of environmental estrogens.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Feldman, D -- Stathis, P A -- Hirst, M A -- Stover, E P -- Do, Y S -- New York, N.Y. -- Science. 1984 Jun 8;224(4653):1109-11.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6372097" target="_blank"〉PubMed〈/a〉
