DNA repair plays an important role in maintaining genomic integrity and in preventing disease development such as cancer development. DNA repair also contributes to cancer cell drug resistance and to antidrug design and development. The research interests of my lab are to understand the mechanism of DNA repair, especially nucleotide excision repair (NER), and its role in environmental carcinogen-caused disease development. Our current research projects include (1) development of new drugs that can sensitize tumor cells to DNA-damaging anticancer drugs and (2) the role and mechanism of DNA repair in environmental carcinogen-caused DNA hypermethylation and cancer. We have already demonstrated the effect of triptolide, a bioactive gradient isolated from herbal plant Tripterygium wilfordii, in sensitizing cisplatin-resistant lung tumor cells to cisplatin. We are currently studying the mechanism by which triptolide sensitizes tumor cells to cisplatin. Our goal is to develop a new anticancer regimen that can dramatically enhance the efficacy of platinum-based anticancer drugs in cancer treatment. In addition, we are also investigating the role and the mechanism of DNMT3A in cigarette smoke and air pollution-caused DNA hypermethylation and lung cancer. Our goal for this study is to understand the molecular mechanism of DNA hypermethylation and cancer and to harness that knowledge to prevent and treat cancer. Many state-of-the-art technologies, including microarray, Next-Gen Sequencing, protein-protein interacts, and Protein-DNA interactions, are applied to our studies.
