FEBS letters 2017 FebAlthough microRNAs and EIF4G2 are both known to play pivotal roles in cancer progression, it remains unknown whether these pathways regulate chemosensitivity in a coordinated manner. Here, we show that miR-379 expression is significantly downregulated in chemoresistant nonsmall cell lung cancer (NSCLC) tissues and cells. Manipulation of miR-379 levels could alter the in vitro and in vivo cisplatin (CDDP) resistance in lung cancer (LCa) cells. Mechanistically, miR-379 potentiated LCa chemosensitivity via modulation of CDDP-induced apoptosis by directly targeting the EIF4G2 3'UTR. Additionally, we observed an inverse correlation between miR-379 and EIF4G2 expression in LCa tissues from patients with CDDP-based chemotherapy. Together, our findings shed new light on the potential involvement of miR-379/EIF4G2 cascade in the pathogenesis of CDDP resistance in LCa. © 2017 Federation of European Biochemical Societies.
