英文摘要

Genistein (GEN) is one kind of phytoestrogen. Several studies have demonstrated the teratogenic potential of GEN in vitro by postimplantation rat whole embryo culture (WEC) assay, but GEN showed no teratogenic effects in vivo even at a dose up to 1000 mg/kg bw/day. The mechanism of such discrepancy is still unclear. Because more than 80% of total genistein (free plus glycoside form) in circulation is its glycoside metabolite, genistin (GIN), we thus hypothesize that genistin is non-teratogenic. To prove this hypothesis, rat whole embryo culture (WEC) and limbud micromass culture methods were applied to compare the teratogenic effects of GEN and GIN on developing embryos in vitro. In WEC assay, we found that the development of embryos was affected by GEN treatment dose-dependently, while GIN-treated embryos displayed slight developmental defects only at the highest dose (222 mu M). In micromass culture assay, the IC50 of cell proliferation and differentiation for GEN were 15.6 and 37.2 mu M, respectively, while neither was influenced by GIN treatment up to 111 mu M. Collectively, our study indicated that GEN showed no teratogenic effects in vivo probably due to its transformation to the non-teratogenic metabolite, GIN. (C) 2012 Elsevier Ltd.
