A role for the dehydrogenase DHRS7 (SDR34C1) in prostate cancer.

ABSTRACT: Several microarray studies of prostate cancer (PCa) samples have suggested altered expression of the "orphan" enzyme short-chain dehydrogenase/reductase DHRS7 (retSDR4, SDR34C1). However, the role of DHRS7 in PCa is largely unknown and the impact of DHRS7 modulation on cancer cell properties has not yet been studied. Here, we investigated DHRS7 expression in normal human prostate and PCa tissue samples at different tumor grade using tissue microarray and immunovisualization. Moreover, we characterized the effects of siRNA-mediated DHRS7 knockdown on the properties of three distinct human prostate cell lines. We found that DHRS7 protein expression decreases alongside tumor grade, as judged by the Gleason level, in PCa tissue samples. The siRNA-mediated knockdown of DHRS7 expression in the h
