Abstract

Several long non-coding RNAs (lncRNAs) have recently emerged as potential biomarkers in cancer biology. In the present study, we examined the expression of four lncRNAs (CAT179, CAT1796, PRCAT47, and CAT1066) to evaluate their ability to discriminate prostate tumors from benign prostate hyperplasia (BPH). Expression of these four lncRNAs was examined in 20 prostate cancer and 20 benign prostate hyperplasia (BPH) samples, as well as in urine samples (11 BPH, and 11 cancer). Total RNA was extracted for cDNA syntheses. The expression of the candidate lncRNAs was evaluated by quantitative real-time PCR (qRT-PCR). The lncRNAs CAT1796 and CAT179 were both upregulated in prostate cancer compared to BPH clinical samples (P<0.05). ROC curve analysis showed that CAT1796 had high sensitivity and specificity for diagnosis of prostate cancer (AUC=0.8151[95%CI 0.65-0.97]), suggesting that CAT1796 lncRNA could be a prostate cancer biomarker. © 2021. by the Serbian Biological Society
