Thus, the aim of the present study was to investigate the effects of miR‑30e and its target gene, M3 muscarinic acetylcholine receptor (CHRM3), on the adhesion, migration, invasion and cell cycle distribution of PCa cells via the mitogen‑activated protein kinase (MAPK) signaling pathway.
In this study, we found that miR-30e was significantly downregulated in tumor tissues of breast cancer (BC) patients and cell lines, and overexpression of miR-30e inhibited cell proliferation, migration and invasion.
Knocking down CBL-B expression phenocopied the effects of miR-30e, whereas ectopic expression of CBL-B suppressed miR-30e-induced EGFR up-regulation and invasion.
