Abstract
The androgen receptor (AR) signaling pathway plays an important role in prostate cancer (PCa) progression. In the present study, a significant co-expression was found between SENPs and AR. In addition, SENP5 was obviously negatively correlated with overall survival and disease-free survival in patients with PCa. Moreover, SENP5 silencing markedly inhibited the proliferation of PCa cells. Chromatin immunoprecipitation quantitative PCR assays further confirmed that AR could transcriptionally activate SENP5 expression. In summary, the present results suggested that SENP5 acts as a downstream target of AR and contributes to PCa growth, the underlying molecular mechanism of which needs further investigation.
