Dr. Chen’s laboratory is interested in understanding the critical role of tumor suppressor genes in the genesis and progression of cancer. Currently, they are putting most of their efforts into elucidating the intracellular signaling pathways involved in the DNA damage response. They are focusing on molecules serving as transducers and effectors, including BRCA1 and BRCA2, members of the BRCT motif-containing family proteins such as NBS1, 53BP1 and NFBD1, and on the DNA repair machinery.  Understanding these signal pathways is vital for solving the puzzle of how cells maintain their genome stability and how specific problems with DNA repair predispose to different cell type-specific cancers.
