LncRNA-MALAT1 mediates cisplatin resistance via miR-101-3p/VEGF-C pathway in bladder cancer.

In this study, we firstly demonstrated that MALAT1 expression was up-regulated in the BC tissues compared to the normal adjacent tissues and elevated in the cancer cells compared to the epithelial immortalized cells. Secondly, we found that suppression of MALAT1 enhanced the chemotherapeutic drug sensitivity and inhibited the cisplatin resistance of the BC cells. Thirdly, we showed that MALAT1 affected the cisplatin resistance of the BC cells via regulating the miR-101-3p/VEGF-C pathway. In summary, this study demonstrates that MALAT1, miR-101-3p and VEGF-C form a regulatory axis to affect the chemo-resistance of BC cells to CDDP, and provides novel potential targets for treatment of BC.
