ABSTRACT
Platinum-based chemotherapy is a common clinical treatment for esophageal squamous cell carcinoma (ESCC), and chemoresistance is a major leading reason for cancer treatment failure. MiR-302a-3p is involved in the development of many diseases. Here, we investigated the role of miR-302a-3p in the cisplatin resistance of ESCC cells and explored its potential mechanism via molecular techniques. The expression of miR-302a-3p was significantly reduced, while the expressions of EphA2 were increased in ESCC tumor tissues and cells. EphA2 was one target gene of miR-302a-3p, and was negatively regulated by miR-302a-3p. By regulating EphA2, miR-302a-3p reduced the viability and promoted the apoptosis of ECA109 cells treated with cisplatin, suggesting that miR-302a-3p could enhance the sensitivity of ECA109 cells to cisplatin treatment by targeting EphA2. MiR-302a-3p plays an important role in reducing cisplatin resistance by inhibiting EphA2, suggesting that it may be a promising therapeutic strategy for cisplatin resistance in ESCC in the future.
