Backgrounds/Aims: Long non-coding RNA (lncRNA) X-inactive specific transcript (XIST) is involved in the progression of several tumors. The interaction between lncRNA and miRNA or miRNA’s target genes is reported to play crucial roles in malignancy. In addition, Androgen receptor (AR) is considered to be involved in bladder cancer progression. In this study, we investigated the role of XIST in human bladder cancer and its interaction with miR-124 and AR. Methods: XIST and AR expression was detected in bladder tumor samples and cell lines. Effects of XIST and AR on bladder cancer cells growth, invasion and migration were analyzed. Bioinformatic analysis and luciferase assays were used to identify the interaction among XIST, AR and miR-124. The correlations of miR-124 with XIST and AR in bladder cancer samples were statistically analyzed. Results: XIST and AR were upregulated in bladder cancer tissues and positively correlated. Higher XIST and AR expression were related to poorer TNM stage of bladder cancer. XIST knockdown reduced bladder cancer cells’ proliferation, invasion and migration. While this inhibitory effect could be partially restored by AR overexpression. XIST inhibited miR-124 expression by directly targeting. Moreover, miR-124 could bind to the 3’UTR of AR to regulate its expression. MiR-124 inhibition partially restored the XIST knockdown-induced reduction of AR, c-myc, p27, MMP13 and MMP9 expression. In bladder cancer tissues, miR-124 level was inversely correlated with the expression of XIST and AR, respectively. Conclusion: These findings indicated that XIST might be an oncogenic lncRNA that promoted the bladder cancer growth, invasion and migration via miR-124 dependent AR regulation.

Abstract. Emerging evidence has demonstrated that androgen receptor (AR) is a promising therapeutic target for bladder cancer. However, the relationship between AR expression and its clinical significance remains controversial. The present in-depth meta-analysis aimed to investigate the correlation between AR expression and clinicopathological features, as well as prognostic value in bladder cancer. A systematic search was performed from PubMed, Web of Knowledge, Embase and the Cochrane Central Search Library by January 2017. The correlation between AR expression and tumor stage, tumor grade, recurrence free survival and progression free survival for patients with bladder cancer was evaluated. A total of 12 relevant studies with 1,652 patient samples were included. AR expression positively correlated with low tumor grade [odds ratio (OR), 1.95; 95% confidence interval (CI), 1.36-2.81], low tumor stage (OR, 2.06; 95% CI, 1.02-4.16) and low recurrence rate [hazard ratio (HR), 0.48; 95% CI, 0.31-0.75] in Caucasian patients. While, its expression had no significant impact on cancer susceptibility (OR, 1.62; 95% CI, P= 0.44) and progression-free survival (HR, 1.20; 95% CI, P=0.77). The present meta-analysis indicated that AR expression correlates with tumor grade, clinical stage and recurrence rates in the specified population and classification system.Further studies are required to determine the precise role of AR in bladder cancer.
