Biographical Narrative

Dr. Dong received her Ph.D. in experimental pathology from the State University of New York at Buffalo in 2000. From 2000 - 2002, she was a postdoctoral fellow in cancer chemoprevention at Roswell Park Cancer Institute. She became a research assistant professor in 2002 and an assistant professor in 2005 in the Cancer Chemoprevention Department. In November 2007, Dr. Dong joined the faculty of Tulane University School of Medicine as an assistant professor in the Department of Structural and Cellular Biology.

Research Interests
The major focuses of the laboratory are to understand the mechanisms involved in resistance of prostate cancer to hormone (androgen-deprivation) therapy and to develop effective approaches to overcome resistance to hormone therapy. Hormone therapy has been shown to lead to upregulated expression of androgen receptor splice variants, which lack the ligand-binding domain but remain constitutively active, in prostate cancer cells. The upregulation contributes to resistance to hormone therapy. Dr. Dong’s laboratory is currently characterizing the mechanisms by which these androgen receptor splice variants mediate therapy resistance, and developing agents to target these androgen receptor splice variants for prostate cancer therapy.
