Personal information
Dr. Siwang Yu graduated with a B. E. from Sichuan Institute of Science and Technology in 1996, then obtained his M. Sc. from Huazhong University of Science and Technology in 2000. In 2003 he graduated with Ph. D. from Peking University School of Pharmaceutical Sciences for his research in the biological effects of lanthanides and underlying cellular and molecular mechanisms. After that he went to USA and joined Ah-Ng Tony Kong’s lab in Ernest Mario School of Pharmacy at Rutgers, The State University of New Jersey as a postdoctoral associate, studying carcinogenesis and cancer chemoprevention. Dr. Yu is now an associate professor in the Department of Chemical Biology, Peking University School of Pharmaceutical Sciences, with his research interests specially focusing on preventive pharmaceutics.
Research interests
The major research interest in Dr. Yu’s lab is Preventive Pharmaceutics, which combines knowledge and methods of chemistry, biology and clinical medicine to discover chemopreventive agents that intervene in the development and progress of major chronic diseases such as cancer and diabetes.
The studies in Dr. Yu’s lab focus on 1) personalized biomarkers of carcinogenesis and chemo toxicities; these biomarkers often are also targets of chemotherapies or alternative/complementary drugs. 2) Discovery of chemopreventive agents based on personalized prediction of predisposition to certain outcomes, such as tumor development, drug resistance or toxicity. These agents could be natural phytochemicals, synthesized chemicals, biological agents, or clinically applied drugs.
Ongoing researches
1、Investigation on the roles of stress responsive transcription factors in carcinogenesis, drug resistance and toxicity/side effects of chemotherapies, and interventions targeting these factors.
2、Utilization and mechanisms of chemicals derived from traditional Chinese herb medicine and edible plants as chemopreventive agents against cancer and diabetes.
