Decreased expression of LncRNA MIR31HG in human bladder cancer

In this study, we examined the relationships between the expression level of long non-coding RNA MIR31HG in bladder cancer and the clinical characteristics.

A total of 55 tissue samples from patients with bladder cancer were collected, and the lncRNA MIR31HG levels in cancer, paired non-cancer tissues and BC cell lines were detected by real-time quantitative RT-PCR (qRT-PCR). The relationships between MIR31HG level and the clinical characteristics were evaluated.

MIR31HG expression was remarkably decreased in bladder cancer tissues compared with adjacent noncancerous tissues (P < 0.05). MIR31HG expression was also significantly down-regulated in four bladder cancer cell lines (P < 0.001). Clinicopathologic analysis revealed that MIR31HG expression was negatively associated with TNM stage (P = 0.010), but not with other clinicopathological characteristics.

These findings revealed that MIR31HG may function as a cancer-suppressor gene to participate in the bladder cancer carcinogenesis and development.
