ABSTRACT
ObjectiveTo discuss the effects of apoptosis and invasion of RBE cells caused by miRNA 21 suppression and further investigate the potential role of miRNA-21 plays on target mRNA regulation. MethodsThe RNAi technology was employed to suppress the expression of RBE cells.The changes in RECK mRNA and protein expressions were detected by RT-PCR and Western blotting respectively. Changes occurred in apoptosis was closely monitored by flow cytometry (FCM). The invasion of RBE cells was analyzed in vitro by invasion assay (transwell). ResultsThe expression of miRNA-21 was clearly suppressed while the RECK mRNA and protein were over-expressed. The rate of apoptosis was significantly accelerated and there was a dramatic decrease in RBE cells' ability to invade after miRNA-21 knockdown. ConclusionThrough miRNA-21 suppression, the rate of apoptosis of RBE cells was accelerated whereas their invasion ability was greatly reduced. RECK was found to be the target gene of miRNA-21 which participates in the regulation process of regulation.
