Cytotoxic signaling mechanisms of anticancer drugs

Our laboratory is interested in basic aspects of cancer chemotherapy, especially the mechanisms that link drug-induced damage to destructive or protective cellular responses.  Our focus has been on understanding the role of Bcl-2 proteins in the mechanism of action of microtubule inhibitors and other anti-mitotic drugs.
