Abstract
Chemotherapy presents the main therapy of non-small cell lung cancer (NSCLC). Nevertheless, cisplatin-based therapy can be limited by drug resistance. MicroRNA (miRNA) possesses a vital regulatory function in modulating the progression as well as cisplatin resistance of NSCLC, but how miR-3195 influences NSCLC is obscure. In this work, it was discovered that miR-3195 presented definite down-regulation in NSCLC cells. Gain-of function assays revealed that overexpressing miR-3195 hindered NSCLC cell proliferation together with migration whereas induced cell apoptosis. Mechanically, 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 4 (PFKFB4) presented the target gene of miR-3195 and was high-expressed in NSCLC cells. The repressive impacts of overexpressing miR-3195 on NSCLC cells malignant behaviors were reversed via PFKFB4 elevation. Additionally, elevated miR-3195 expression reduced cisplatin resistance of NSCLC both in vitro as well as in vivo. PFKFB4 elevation could offset the reduced cisplatin resistance caused by miR-3195 overexpression in NSCLC cells. In conclusion, this work clarified miR-3195 repressed NSCLC cell proliferation, migration, as well as cisplatin resistance by modulating PFKFB4. Our study might provide a promising clue to promote the anti-tumor effects of chemotherapy.
