Ping Mu received his B.S. in Biotechnology from Peking University, Beijing, China (2007). He earned his Ph.D. in Biomedical Sciences (Cancer Biology) from Weill Cornell Medical College (2013), where he worked with Dr. Andrea Ventura. There, he identified a microRNA called miR-19 as a crucial oncogenic driver of Myc-driven B cell lymphoma and prostate cancer. In 2013, Ping joined the laboratory of Dr. Charles L. Sawyers as a postdoctoral fellow at Memorial Sloan Kettering Cancer Center, New York. His work focused on identifying a novel mechanism of antiandrogen resistance in prostate cancer mediated by increased lineage plasticity, or “identity fraud.” This lineage plasticity is enabled by the activation of SOX2 and can be reversed by SOX2 inhibition, which raises the hope that appropriate clinical intervention of lineage plasticity could prevent or overcome resistance.
After joining the faculty of UTSW in 2018, Ping and his team conducted an in vivo library screen investigating novel gene deletions which confer resistance to AR targeted therapy. Through this library screening, Mu lab has identified the loss of CHD1, an ATP-dependent chromatin remodeler frequently deleted in prostate cancer, confers resistance to AR targeted therapy and is correlated with worse clinical outcomes. The Mu lab then demonstrated that CHD1-loss, through global effects on chromatin, establishes a state of plasticity that accelerates the development of resistance through activation of heterogeneous effectors, which mediate the transition away from luminal lineage and AR dependency. This work suggests that proper clinical intervention of these resistance drivers may be a novel avenue which can be exploited to overcome resistance.
Besides CHD1, Mu lab has identified several other novel genomic alterations which confer resistance to AR targeted therapy. Elucidating the mechanisms by which these genes confer resistance will help us understand AR targeted therapy resistance and develop new therapeutic strategies to prevent or overcome resistance and benefit patients with advanced prostate cancer. Ping is the recipient of a DoD PCRP Postdoctoral Training award (2014), a NIH K99/R00 Pathway to Independence award (2017), a Prostate Cancer Foundation Young Investigator award (2017), a Cancer Prevention Research Institute of Texas (CPRIT) Recruitment of First-Time, Tenure-Track Faculty Member award (2017) and a DoD Idea Development Award (2018). He is also the Deborah and W.A. “Tex” Moncrief, Jr. Scholar in Medical Research.
