Research Interest:

DNA damage repair (DDR) deficiency and lethal prostate cancer: Unlike many cancers driven by a small number of hotspot mutations, prostate cancer is driven more by somatic copy number alteration (CNA), which affects large segments of chromosomes. Since CNA burden is associated with DDR alteration, therefore, DDR pathway alterations are more frequent in lethal prostate cancer than previously reported. The prevalence of germline and somatic mutations in BRCA2, a hallmark DDR gene, are significantly increased in metastatic castration-resistant PC (mCRPC) compared to localized PC. We are investigating the molecular insights of BRCA2/DDR alterations in prostate cancer biology for consideration of DDR alteration as the master driver of the transformation from indolent, localized prostate cancer to lethal mCRPC.
Overcoming PARP inhibitor resistance: Cancer cells with alterations in DDR genes are hypersensitive to drugs that inhibit PARP. These findings led to the recent FDA approval of PARP inhibitors for patients with several cancer types, though the effects are not durable. Our research has focused on uncovering mechanisms of resistance to PARP inhibitors, with the ultimate goal of identifying therapeutic strategies to overcome this resistance and developed rational for future clinical trials.
Metabolism, genetic abnormalities and cancer progression: Despite the many recent efforts, the metabolic reprogramming of cancer cells is far from fully characterized primarily because of our lack of knowledge on how a genetic abnormality turns on or reprograms a metabolic switch in cancer cells. Our research focuses on the interplay between clinically relevant genetic mutations and the rewriting of the metabolic pathways in cancer cells, thereby identifying targetable molecular pathways to reduce the cancer burden.
Y-Chromosome and cancer: Cancer affects men and women differently. Much of the sex difference in cancer rates is due to lifestyle factors, especially smoking,which historically has been more common in men. But even some cancers that are not known to be linked to lifestyle tend to appear more often in men. We will undertake an innovative research approach to ask why. The focus of our efforts is the most fundamental difference between men and women: the Y chromosome. Though loss of the Y chromosome (ChrY) in men has been associated with increased risk of cancer including prostate cancer and mortality, the role of ChrY genes in cancer progression is poorly understood. We are investigating the mutational landscape of ChrY and determine if the loss of Y-chromosome (LOY) is significantly associated with disease risk in men.
