MicroRNAs (miRNAs) have been extensively studied over the decades and have been proposed as potential molecular targets for cancer treatment. Studies have shown that miR-378 participates in numerous biological processes in various cancers; whereas miR-1827 has only been reported in pediatric glioma. The mechanism of how miRNAs modulate lung cancer metastasis remains unclear. Our previous study demonstrated that miR-378 is up-regulated while miR-1827 is down-regulated in high invasive lung cancer sub-cell lines, and their biological functions have been described. Here, we report that miR-378 and miR-1827 modulate lung cancer cell invasion and migration via epithelial-mesenchymal transition (EMT). We also demonstrated that cells treated with miR-378 inhibitors or miR-1827 mimics had reduced number of metastases and ectopic vessels in the zebrafish embryo model. We then showed that miR-378 promoted invasion and miR-1827 suppressed migration by targeting RBX1 and CRKL, respectively. Restored protein expression in miRNA-overexpressed/ miRNA-suppressed cells attenuated the inhibitory/ inducing effect of the miRNA on lung cancer cells. Collectively, our findings highlight that miR-378 and miR-1827 could serve as novel therapeutic targets in lung cancer.
