Clinically high-grade prostate cancers (PC) with high Gleason scores of 8-10 exhibit rapid growth and are more likely to spread beyond the prostate. These cancer types demonstrate a poor response to androgen deprivation therapy and eventually acquire a castration-resistant phenotype. To identify novel molecular cancer drug targets, we previously analyzed the gene expression profiles of high-grade PC using a cDNA microarray combined with laser microbeam microdissection and found a number of genes that are transactivated in high-grade PC. Among these genes, we report the identification of a novel molecular target, small nuclear ribonucleoprotein polypeptide E (SNRPE). Semi-quantitative RT-PCR confirmed that SNRPE is overexpressed in high-grade PC cells compared with normal prostatic epithelial cells. Knockdown of SNRPE expression by short interfering RNA (siRNA) resulted in the marked suppression of PC cell proliferation. By contrast, SNRPE overexpression promoted PC cell proliferation, indicating its oncogenic effects. Furthermore, we demonstrated that SNRPE regulates androgen receptor (AR) mRNA expression in PC cells. Knockdown of SNRPE expression by siRNA resulted in the marked suppression of AR and its downstream target genes at the mRNA level. We suggest that the regulation of AR expression by SNRPE is essential for cell proliferation and progression of high-grade PC and that it may be a novel molecular target for cancer drugs.
