Research Interests
Mammary glands undergo structural remodeling and biochemical changes from embryogenesis through aging in females. This process is tightly regulated by hormones and involves a complex cooperation of a variety of genes participating in cell division, proliferation, matrix degradation and remodeling. Like mammary epithelial cells breast cancer tumors require estrogen for continued growth. Anti-estrogen therapy alone or in combination with other drugs, has long been a common procedure for breast cancer treatment and prophylaxis. The clinical efficacy of an anti-estrogen tamoxifen (TAM) has been attributed to growth arrest and induction of apoptosis in breast cancer cells, but the ability of TAM as a potential modulator of tumor suppressor genes has never been reported.
Maspin, a serine protease inhibitor (serpin), is highly expressed in normal mammary and reproductive organs, and is believed to play a critical role in mammary gland development. Maspin is present in high concentrations in normal mammary epithelial (and myoepithelial) cells, but its expression is down-regulated in primary breast cancer and lost in metastatic cells. Maspin promoter contains hormone response element and AP1 sites and maspin induction following androgen ablation and/or radical prostectomy in prostate cancer have been reported. Thus, we hypothesized that that tamoxifenís anti-tumor action could also be mediated, at least in part, through its ability to induce the tumor suppressor gene maspin. We are currently studying the effect of TAM (over various time period) on maspin expression in normal mammary epithelial cells and breast cancer cell lines and verifying our observations in patients tissue.
Recent studies have also indicated the importance of sex hormones and gender in autoimmune disorders such as rheumatoid arthritis. Regulation of immune response, matrix metalloproteinases and cytokine system by hormones could have a direct effect on cartilage and synovial tissue. Thus, we hypothesized that sex hormones could exert direct and indirect effects on cartilage synthesis and degradation and thus modulate the course of the disease. Studies in our lab are directed to answer such questions.
