越来越多的人担心,作为内分泌干扰物的雌激素环境化合物可能会对荷尔蒙敏感的器官(如乳房)产生不利影响。有证据表明,天然雌激素,特别是17-雌二醇(17β-estadiol,E2)是乳腺癌发生和发展的重要因素,这进一步加剧了人们的担忧。我们已经建立了一个体外-体内模型,在该模型中,我们已经证明了E2在人乳腺上皮细胞MCF-10F中的致癌作用。在该模型中,NRG1、STXBP6、Bmp6、CSS3、SPRY1和SNIP的甲基化发生在不同的进展阶段。这一强大而独特的模型的应用为探索双酚A(BPA)和邻苯二甲酸丁基苄酯(BBP)是否与乳腺癌的发生有关提供了工具。这些研究提供了第一手证据,证明天然雌激素17,β-雌二醇和异种雌激素物质,如双酚A,能够诱导人乳腺上皮细胞发生肿瘤转化。
There is growing concern that estrogenic environmental compounds that act as endocrine disrupting chemicals might potentially have adverse effects on hormone-sensitive organs such as the breast. This concern is further fueled by evidence indicating that natural estrogens, specifically 17 β-estradiol (E2), are important factors in the initiation and progression of breast cancer. We have developed an in vitro- in vivo model in which we have demonstrated the carcinogenicity of E2 in the human breast epithelial cells MCF-10F. Hypermethylation of NRG1, STXBP6, BMP6, CSS3, SPRY1 and SNIP were found at different progression stages in this model. The utilization of this powerful and unique model has provided a tool for exploring whether bisphenol A (BPA) and butyl benzyl phthalate (BBP) have relevance in the initiation of breast cancer. These studies provide first hand evidence that the natural estrogen 17 β-estradiol and xenoestrogenic substances like BPA are able to induce neoplastic transformation in human breast epithelial cells.
