Research Area:
Professor Yuxin Yin’s research field is cancer genetics with main focus on the roles of tumor suppressors p53 and PTEN in cell
cycle regulation, apoptosis and genomic stability.  In 1992, he found a fundamental role of p53 in controlling the G1 checkpoint and maintaining genomic stability.  In 1998, he reported that p53 is required for the cellular apoptotic response to oxidative stress. In 2003, his team at Columbia demonstrated that PAC1 phosphatase is a direct transcriptional target of p53 in signaling apoptosis and tumor suppression, establishing a link between p53 and the MAP kinase cascade.  They also found that RAD9 is a transcription factor and that RAD9 can regulate p21 and other genes involved in cell cycle checkpoints and embryogenesis. In 2007, his group reported that PTEN plays a fundamental role in the maintenance of chromosome stability and that PTEN does so through physical interaction with centromeres.  In 2010, Dr. Yin established a laboratory of Cancer Genetics in the Institute of Systems Biomedicine at Peking University Health Science Center.  In recent years, his team has been investigating novel functions of nuclear PTEN in regulating the mitotic checkpoints. They also study the mechanism of the network of tumor suppressors. Their recent study reveals that the transcription factor CREB is a novel nuclear target of PTEN.
