miRNA-21减轻氧糖剥夺对PC12细胞的损伤
[Abstract]:Objective: to investigate the effect of RNA (miRNA)-21 on hypoxic ischemic PC12 cells. Methods: PC12 cells were cultured in vitro, and the model of (OGD) damage induced by oxygen glucose deprivation was established. The cells were randomly divided into control group (OGD group), negative control group (OGD group), miRNA-21 inhibitor OGD group and miRNA-21 mimic OGD group. To investigate the effect and mechanism of miRNA-21 on PC12 cells damaged by OGD by means of CCK-8,real-time PCR,Western blot and other techniques. Results: the activity of PC12 cells damaged by OGD decreased significantly when the expression of miRNA-21 was decreased, and the activity of PC12 cells injured by OGD increased significantly when the expression of miRNA-21 was increased. It was further found that miRNA-21 promoted AKT phosphorylation in PC12 cells damaged by OGD. ConclusionThe activity of PC12 cells damaged by OGD was significantly increased by% miRNA-21, and the mechanism may be related to the activation of PI3K/AKT signaling pathway.
