Our major disease interest is prostate cancer, with a particular focus on the role of the androgen receptor in prostate cancer development and progression. We are studying molecular mechanisms of androgen receptor action in normal prostate and prostate cancer. These include studies of AR structure, AR mutations, DNA binding, and interactions with coactivator/corepressor proteins. The lab has identified several androgen interacting proteins, and a long term objective is to develop novel androgen receptor antagonists that will selectively modulate androgen receptor protein interactions. Other objectives are to establish animal models of prostate cancer and to carry out translational studies on clinical materials from prostate cancer patients.
