      Department of Genetics, Division of Division of Discovery Science

      About Dr. Shunbin Xiong

      Shunbin Xiong was born in southeast region of China, and received his bachelor degree in Biochemistry at Fudan University in Shanghai. He completed his Ph.D. at the Institute of Biochemistry and Cell Biology, Shanghai Institutes for Biological Sciences, Chinese Academy of Sciences. After he finished his postdoctoral training in Baylor College of Medicine, he moved to The University of Texas, M.D. Anderson Cancer Center in 1999. He is currently an Assistant Professor in the Department of Genetics.

      Dr. Xiong’s research focus is to investigate p53 pathway using genetically modified mouse models. Tumor suppressor gene p53 is often mutated or inhibited by its negative regulators, Mdm2 and Mdm4, in human cancers. Dr. Xiong has discovered Mdm2 and Mdm4 cooperatively inhibit p53 activity during the development of the central nervous system, and Mdm2 and Mdm4 suppress p53 activity in embryonic development and adult stage, respectively. Furthermore, he shows overexpression of Mdm4 induces tumorigenesis and has a p53-independent function in mice. Dr. Xiong also demonstrates that Mdm4 overexpression cooperates with an oncogenic K-ras mutation to drive lung tumorigenesis in vivo. Dr. Xiong is also working on mutant p53 gain of function (GOF) in tumorigenesis and cancer metastasis. His work indicates phospholipase Pla2g16 mediates mutant p53 GOF in osteosarcoma metastasis. Dr. Xiong has also discovered different p53 mutations driving mammary tumorigenesis with distinct GOF ability. His research goal is to understand p53 pathway in vivo and identify therapeutic targets in cancer treatment.
