报告人简介：

Professor Chen’s group has long standing research interests in understanding the molecular mechanisms of genomic instability and tumorigenesis. The maintenance of genomic integrity following DNA damage depends on the coordination of DNA repair with cell cycle checkpoint control. The integrity of the DNA damage response pathway is crucial for the prevention of neoplastic transformation, as suggested by the fact that many proteins involved in these pathways are tumor suppressors including BRCA1, BRCA2, ATM, RPA1 and FANC family. In recent years, Dr. Chen’s group has discovered a number of components that function in the DNA damage and repair pathways.
