1. Developing novel therapeutic strategies for unmet clinical needs in clear cell and endometrioid histosubtypes of epithelial ovarian cancer, the most lethal gynecological malignancy is the developed world. For example, clear cell ovarian cancer carries worst prognosis when diagnosed at advanced stages because there is currently no effective therapeutic treatment. Our published works explored new therapeutic strategies based on unique genetic makeup such as ARID1A mutation in clear cell and endometrioid epithelial ovarian cancer.

4. Identification of novel pathways regulating cellular senescence through epigenetic mechanisms and their implications in ovarian cancer. We defined key epigenetic regulators such as HIRA/ASF1a complex, HMGB2 and RNA m6A methyltransferase complex that drive changes in the chromatin landscape during senescence.

5. Understanding the role of DNA damage and metabolic pathways in mediating senescence-associated cell growth arrest. Our study helps explain a major paradox in the senescence field: How activated oncogenes induce senescence but at the same time predispose cells to transformation through BRCA1 pathway. In addition, we explored the role of metabolic pathways in regulating replication stress and DNA damage during senescence.
