Abstract:
:Prostate cancer (PCa) is the second leading cause of death among American men. Increasing evidence has shown that long noncoding RNAs (lncRNAs) play important roles in tumorigenesis of PCa. In this study, we explored the biological functions of small nucleolar RNA host gene 12 (SNHG12) and investigated the interaction between miR-133b and SNHG12 in the progression of PCa. Data was downloaded from The Cancer Genome Atlas and Human Cancer Metastasis Database, and clinicopathological characteristics were analyzed with relapse-free survival rate. We detected SNHG12 expression level in PCa cells and tissues, and then analyzed its clinical significance, which revealed that SNHG12 has the potent to predict prognosis of PCa. Bioinformatic analysis revealed that SNHG12 was closely related to the progression of PCa and could target candidate microRNA (miR-133b). After transfecting SNHG12 silencing plasmid and miR-133b mimic/sponge, biological function assays were conducted and results illustrated that SNHG12 associated with miR-133b exerted biological effects on cancer cell growth, migration, and invasion. Direct interactions between miR-133b and SNHG12 have been found and SNHG12 acts as an oncogene to promote tumorigenesis of PCa by sponging tumor suppressor gene miR-133b.
