Propofol suppresses growth, migration and invasion of A549 cells by down-regulation of miR-372
Abstract Background Propofol, a commonly used intravenous anesthetic during cancer resection surgery, has been found to exhibit tumor inhibitory effects in vitro and in vivo. The role of propofol in lung cancer has been previously reported, whereas its action mechanism remains unclear. This study fu...

| description | Abstract Background Propofol, a commonly used intravenous anesthetic during cancer resection surgery, has been found to exhibit tumor inhibitory effects in vitro and in vivo. The role of propofol in lung cancer has been previously reported, whereas its action mechanism remains unclear. This study further investigated the effects of propofol on lung cancer A549 cell growth, migration and invasion, as well as the underlying mechanisms. Methods Cell viability, proliferation, migration, invasion and apoptosis were assessed by CCK-8 assay, BrdU assay, two chamber transwell assay and flow cytometry, respectively. The regulatory effect of propofol on microRNA-372 (miR-372) expression in A549 cells was analyzed by qRT-PCR. Cell transfection was used to change the expression of miR-372. The protein expression of key factors involving in cell proliferation, apoptosis, migration and invasion, as well as Wnt/β-catenin and mTOR pathways were analyzed by western blotting. Results Propofol inhibited lung cancer A549 cell viability, proliferation, migration, and invasion, but promoted cell apoptosis. Moreover, miR-372 was down-regulated in propofol-treated A549 cells. Overexpression of miR-372 abrogated the effects of propofol on proliferation, migration, invasion and apoptosis of A549 cells. Knockdown of miR-372 had opposite effects. Furthermore, propofol suppressed Wnt/β-catenin and mTOR signaling pathways by down-regulating miR-372. Conclusion Propofol inhibits growth, migration and invasion of lung cancer A549 cells at least in part by down-regulating miR-372 and then inactivating Wnt/β-catenin and mTOR pathways. |
