About Shao-Yong Chen, PhD
More than 10 years ago before Dr. Chen came to USA, he studied biosynthesis
of steroids by fungi in China. His scientific journey on the molecular
basis of prostate cancer (PCa) development and androgen receptor (AR)
regulation was started since he worked as a PhD student in USA. His PhD dissertation work was mainly focused on several co-factors of AR-mediated
transcription and AR-dependent transcriptome. His research at BIDMC
(Harvard Medical School) was initiated with the unexpected finding that the
peptidyl-prolyl isomerase Pin1 has opposite effects on the AR and Wnt
pathways. This work led to the realization the importance of studying AR
phosphorylation. For the past few years, he has investigated the mechanisms
and significance of AR phosphorylation and dephosphorylation at the
molecular and cellular levels. His future direction is to continue the
study of AR regulation and to identify updated strategies to overcome
advanced PCa diseases. His research contains basic and translational
components and should have both biological and clinical impacts on prostate
cancer research.
