    Abstract:
    Increasing evidence has confirmed that dysregulation of microRNAs (miRNAs) can contribute to the progression and metastasis of human tumors. Previous studied have shown dysregulation of miR-24 in a variety of tumors. However, the roles of miR-24 in human bladder cancer have not been well clarified. Therefore, we investigated the biological functions and molecular mechanisms of miR-24 in human bladder cancer cell lines, evaluating whether it could be a therapeutic biomarker of bladder cancer in the future. In our study, we found that miR-24 is downregulated in human bladder cancer cell lines. Moreover, the low level of miR-24 was associated with increased expression of CARMA3 in bladder cancer cells. Upregulation of miR-24 significantly inhibited proliferation, arrested cell cycle and induced apoptosis in bladder cancer cells. In addition, invasion and epithelial to mesenchymal transition (EMT) of bladder cancer cells was suppressed by overexpressing miR-24. Bioinformatics analysis predicted that the CARMA3 was a potential target gene of miR-24. Further study by luciferase reporter assay demonstrated that miR-24 could directly target CARMA3. Overexpression of CARMA3 in bladder cancer cells transfected with miR-24 mimic partially reversed the inhibitory effect of miR-24. In conclusion, miR-24 inhibited cell proliferation, invasion and EMT in bladder cancer cells by downregulation of CARMA3, and that downregulation of CARMA3 was essential for the miR-24-inhibited cell proliferation, invasion and EMT in bladder cancer cells.
