Abstract

Introduction: Endothelin receptor type B (EDNRB) is a potential target gene of miR-124-3p, but the association between miR-124-3p and EDNRB has not yet been reported. The aim of this study was to investigate the role of miR-124-3p in bladder cancer (BC) and to determine whether miR-124-3p regulates cell proliferation by targeting EDNRB.

Material And Methods: Bladder cancer tissues and cell lines were obtained in order to analyze the miR-124-3p and EDNRB expression through quantitative RT-PCR (qRT-PCR) and western blotting analysis. The dual-luciferase reporter assay was employed to confirm the relationship between miR-124-3p and EDNRB. The manipulation of miR-124-3p and EDNRB expression was achieved through cell transfection. Cell proliferation and apoptosis were evaluated by MTS assay, colony forming assay and flow cytometry. A nude mouse tumorigenicity assay was used to detect the effects of miR-124-3p .

Results: There was an inverse correlation between the expression of miR-124-3p and EDNRB; miR-124-3p was down-regulated and EDNRB was up-regulated in BC tissues and cell lines. MiR-124-3p was observed to target EDNRB and suppress its expression. Other studies have suggested that the transfection of miR-124-3p mimics and EDNRB siRNA can suppress BC cell proliferation and induce cell apoptosis.

Conclusions: miR-124-3p regulates the proliferation and apoptosis of BC cells by suppressing EDNRB expression.
