Bone marrow mesenchymal stem cells-derived exosomal microRNA-193a reduces cisplatin resistance of non-small cell lung cancer cells via targeting LRRC1.

ABSTRACT: Exosomes are small endogenous membrane vesicles that can mediate cell communication by transferring genetic materials. Based on that, exosomes have always been discussed as a cargo carrier for microRNA (miRNA) transportation. Accumulating data have reported the inhibitory effects of microRNA-193a (miR-193a) on non-small cell lung cancer (NSCLC) cell progression. However, the mechanisms of miR-193a delivery to cancer cells and miR-193a in exosomes have not been explored clearly in NSCLC. Given that, this work aims to decode exosomal miR-193a in cisplatin (DDP) resistance of NSCLC cells. A549 and H1299 cell lines were screened out and their parent cells and drug-resistant cells were co-cultured with human bone marrow mesenchymal stem cells (BMSCs)-derived exosomes (BMSC-Exo) that had been tr
