Molecular Endocrinology and Toxicology. My laboratory is investigating timing of exposure/treatment (prenatal, neonatal, prepubertal, life-time) for causing developmental alterations to the reproductive tract/endocrine system. Our focus has been on the effects that estrogenically-active chemicals can have on the breast, uterus, prostate and testes, and for fertility and endocrine action. We look at beneficial as well as toxic effects. Studies are carried out at the biochemical, cellular and molecular levels.
We were the first to report that early exposure to genistein, a component of soy, protected against chemically-induced mammary cancer. Genistein is capable of causing early mammary gland differentiation that subsequently results in reduced cell proliferation. In another study, we have demonstrated that dietary genistein protects against prostate cancer in a chemically-induced rat model and protects against spontaneously developing prostate cancer in a transgenic model (TRAMP mice). We are presently investigating sex steroid and growth factor signaling pathways and DNA methylation as mechanisms of action for (-) epigallocatechin-3-gallate, resveratrol and genistein.
Recently, we have discovered that resveratrol, a component of red wine, protects against mammary gland and prostate cancers. We are presently investigating mechanisms of action.
Environmental chemicals such as TCDD, DDT, PCBs and Bisphenol-A are being investigated as endocrine disruptors. Early exposure to these estrogenically-active xenobiotics alters estrus cycle, vaginal opening, and mammary gland differentiation and cell proliferation. Present studies are concerned with the molecular expression of steroid receptors, and growth factor ligands and receptors using reverse transcription-PCR, Southern- and western- blot analysis, and proteomic technology.
