Li Xin, Ph.D.



Dr. Xin received the award for his concentration on the initiation of prostate cancer as it is affected by inflammation that alters prostate lineage differentiation. His work has identified the dual nature of the Notch protein in prostate disease – suppressing proliferation of the prostate basal cell while inducing luminal cell hyperproliferation, thus showing how this critical protein affects prostate cancer initiation. Dr. Xin’s work provides a critical insight into the nature of prostate cancer in an area that has been understudied, and his future work promises to bring new clarity to prostate stem cell biology and the metastasis of this difficult disease.

Dr. Xin's nomination was based on the following publications:
