Genomic Instability and
Tumorigenesis Laboratory

The research interests of our laboratory include the molecular
mechanisms of DNA damage repair, chromatin remodelling,
epigenetic modifications, and their roles in postnatal
development and carcinogenesis. We are also interested in
translational studies. Our research may not only reveal
the causes of tumorigenesis and other genetic diseases,
but also contribute for diagnostics and therapeutics of
these diseases in the near future.

About Research

The research interests of our laboratory include the mechanisms of DNA damage response, chromatin remodeling, epigenetic modifications, and their roles in tumorigenesis.

As a principle investigator, I have extensive expertise and motivation necessary to successfully carry out the research projects that are supported by various funding agencies. The research conducted in my laboratory results a number of manuscripts published in leading journals. Eight trainees from my laboratory have successfully become independent investigators, established their own laboratories, and generated scientific contributions in the cancer research field. Our current research mainly focuses on the role of protein poly(ADP-ribosyl)ation in DNA damage repair and cancer chemotherapy. Poly(ADP-ribosyl)ation is an unique posttranslational modification induced by DNA damage. Targeting poly(ADP-ribosyl)ation by PARP inhibitors suppresses DNA damage repair and selectively kill tumor cells with DNA damage repair defectives. Our recent studies not only reveal the basic molecular pathway of poly(ADP-ribosyl)ation in DNA damage repair, but also suggest novel therapeutic targets in this pathway for future cancer treatment. In addition, we recently developed small molecule inhibitors specifically targeting dePARylation enzymes for cancer chemotherapy.
