Dr. Dianzheng Zhang, Associate Professor, assumed a tenure-track position in the Department of Biochemistry/Molecular Biology at PCOM in 2006 after three and a half years of postdoctoral research in the Department of Molecular & Cellular Biology at Baylor College of Medicine.
Dr. Zhang's general research interests are in the nutrient control of gene expression (transcriptional and translational) in health and diseases. As living organisms we continuously exchange chemical components with the environment; through this exchange, nutrients are implicated in the regulation of gene expression and cell fates, which ultimately confer life or death. With increasing knowledge of the importance of nutrition in our aging population, medicine is shifting its focus from the treatment of acute diseases to the prevention of cancer and chronic diseases. It has been estimated that thirty to fifty percent of all cancers could be prevented by attention to dietary factors. Dr. Zhang is particularly interested in the regulation of gene expression by micronutrients, such as vitamins and minerals, as well as phytochemicals. Presently, Dr. Zhang's research is focused on the molecular mechanisms of different phytochemicals in prostate cancer chemoprevention. Presently, there is a technician, two MS students and a few DO (Doctor of Osteopathy) student working in Dr. Zhang's laboratory.
In addition, Dr. Zhang also holds a visiting professor position at the Central South University in the People's Republic of China, which will foster international collaborations in both medical teaching and research.
