My laboratory studies molecular mechanisms that regulate cancer development, growth, invasion, and metastasis, and novel experimental therapeutics for cancer prevention and treatment using molecular and cellular biology, and bioinformatics techniques and animal model systems. Ongoing research projects include the investigation of how aging, obesity, radiation, and xenoestrogens may induce a tumorigenic phenotype of mammary stem cells and the investigation of the roles of transforming growth factor-beta (TGFβ), hedgehog, and androgen signaling pathways in various types of cancer. We are developing therapeutic approaches for the prevention of aging-associated breast cancer and for abrogating TGFβ, hedgehog, and androgen signaling pathways for the treatment of aggressive cancers including castration resistant prostate cancer.
