miR-21 promotes growth, invasion and migration of lung cancer cells by AKT/P-AKT/cleaved-caspase 3/MMP-2/MMP-9 signaling pathway.

This study aimed to demonstrate the effects of miR-21 on the growth, migration, and invasion of lung cancer cells A549 in vitro and the possible mechanism.In vitro cell migration and invasion potential were determined by Transwell chamber assays. FACS was used to assess the effect of miR-21 on A549 cell cycle and apoptosis. 4-6 week-old female mice were utilized to establish a lung cancer model. The pathologic biopsy was processed by H&E...
