Abstract

MicroRNA-34a (miR-34a) serves as a tumor suppressor in a number of different types of cancer. The present study was performed to investigate the involvement of miR-34a in bladder cancer. In the present study, miR-34a was downregulated in patients with bladder cancer compared with the healthy controls in bladder biopsies and plasma. Downregulation of miR-34a distinguished between patients with bladder cancer and the healthy controls. miR-34a expression was associated with tumor metastasis; however, not with tumor size. Transfection of miR-34a mimics upregulated the expression of phosphatase and tensin homolog (PTEN) in bladder cancer cells, and decreased cell migration and invasion. miR-34a may inhibit bladder cancer cell migration and invasion by upregulating PTEN. miR-34a may additionally serve as a potential therapeutic target for bladder cancer.
