Research in her laboratory is focused on understanding the molecular mechanisms of action of natural products for cancer prevention and therapy by targeting the proteolysis pathway. The discovery of the ubiqutin-proteasome system opens up a new way for cancer therapy. Using the proteasome as a ligand, several traditional Chinese medicinal compounds have been found to bind and inhibit the proteasome beta5 subunit by in silico docking screening, which proteasome inhibitory activities and anti-tumor effects have been verified in prostate cancer cells and human prostate cancer xenografts in nude mice. The proteasome inhibitors are able to induce cell cycle arrest and trigger apoptotic cell death in human prostate cancer through accumulation of the cyclin-dependent kinase inhibitors p21 or p27, and pro- apoptotic proteins such as Bax. Protein degradation mainly depends on the ubiquitin-proteasome system and autophagy lysosome pathway, which are believed to cross-link with each other. Currently her lab is interested in understanding the role of transcription factors or miRNAs in the regulation of proteasome inhibitor induced autophagy. Other studies are directed toward elucidating the role of chemopreventive agents in sensitization of cancer cells to conventional therapeutics.
