Prostate cancer non-coding RNA 1 (PRNCR1); prostate-specific transcript 1 (PCGEM1)

In vitro, cell culture and mouse studies suggest inhibiting the long noncoding RNAs (lncRNAs) PRNCR1 or PCGEM1 could help treat prostate cancer. Chromatin isolation by RNA purification and in vitro binding studies showed that the lncRNAs PRNCR1 and PCGEM1 bound directly to androgen receptor (AR) and associated with AR-regulated genes in a prostate cancer cell line. In this cell line, small hairpin RNA knockdown of either lncRNA decreased AR signaling compared with no knockdown. In a mouse xenograft model of prostate cancer, shRNA against either lncRNA decreased tumor growth compared with control shRNA. Next steps include additional studies on the expression of PRNCR1 and PCGEM1 in prostate cancer patient samples (see IncRNA meets the androgen receptor, page 4).
