Effect of TET2 on the activity and motility of non-small cell lung cancer cells
Objective To observe the effects of methylenedioxygenase(TET2)expression on the proliferation ability,apoptosis rate,cell cycle,migration,and invasion of non-small cell lung cancer cells.Methods Detect the expression of TET2 gene and protein in different non-small cell lung cancer cells through RT-PCR and Western blot.Knock down the gene expression of the highest TET2 expressing cells(shRNA1)and overexpress the gene in the most low TET2 expressing cells(OE-TET2).Detect the effect of TET2 expression on cell proliferation through CCK-8,observe the effect of TET2 expression on cell apoptosis and cell cycle through flow cytometry,and observe the effect of TET2 expression on cell migration and invasion ability through migration and invasion experiments.Results The expression levels of TET2 gene and protein in H1299 cells were the highest,while A549 cells had the lowest expression levels(P＜0.05).The proliferation ability of OE-TET2 group cells was significantly lower than that of normal A549,while the proliferation ability of shRNA1 group cells was significantly higher than that of normal H1299 cells(P＜0.05).The apoptosis rate of OE-TET2 group was significantly higher than that of normal A549 cells,while the apoptosis rate of shRNA1 group was significantly lower than that of normal H1299 cells(P＜0.05).The number of migration and invasion cells in the OE-TET2 group was significantly lower than that of normal A549 cells,while the migration and invasion cells in the shRNA1 group were significantly higher than those in normal H1299 cells(P＜0.05).Conclusion TET2 can reduce the proliferation ability,increase its apoptosis rate,and slow down its migration and invasion ability of non-small cell lung cancer cells.
