Increased expression of long non-coding RNA GLIDR in prostate cancer.

Prostate cancer (PCa) was one of the most common cancers in males in China. Long non-coding RNAs (lncRNA), a class of non-coding RNAs with more than 200 nucleotides, played key roles in the progression of prostate cancer. GLIDR, a novel long intergenic ncRNA, was found to be upregulated in tumors compared to normal tissues by using publically databases. In the clinical validation cohort, our results showed GLIDR was significantly up-regulated in prostate cancer samples and cell lines. To explore the potential functions of the GLIDR, we constructed gene co-expression networks and applied GO analysis. Our analysis revealed that GLIDR was involved in the regulation of translational elongation, transcription, rRNA processing, RNA splicing, signal transduction, and cell adhesion. Furthermore, a GLIDR-mediated ceRNA network in prostate cancer was also identified. We believed that this study still provided some clues in exploring new therapeutic and prognostic targets for prostate cancer.
