ABSTRACT
Objective:To investigate the effects of scutellarin on Bcl-2 and Bax expression in human tongue squamous carcinoma Tca-8113 cell.Methods:Tca8113 cells were treated with 80,120 and 160μg/ml scutellarin for 48 h respectively.Immunocytochem-istry method and RT-PCR were applied to observe the expression of Bcl-2 and Bax protein and mRNA in the cells.Results:With the increase of scutellarin concentration,Bcl-2 protein and mRNA decreased(P<0.05),Bax protein and mRNA increased(P<0.05). Conclusion:Scutellarin may downregulate Bcl-2 expression and upregulate Bax expression in Tca-8113 cells.
ABSTRACT
Objective:To explore the effects of NOD2 gene on the proliferation and apoptosis of tongue squamous cell carcinoma Tca8113 cells.Methods:NOD2 expression vector(NOD2-pEZ-M29)and NOD2-shRNA vector were established,then were trans-fected into Tca8113 cells respectively.Expressions of HBD-2 and NOD2 in the cells was detected by RT-PCR and Western blot.Cell proliferation was examined by MTT assay and apoptosis by flow cytometry at 48h post transfection.Results:Compared with the control group,the expression of NOD2 and HBD-2 in NOD2-pEZ-M29 transfection group was significantly higher and markedly lower in NOD2-shRNA group.The proliferation rate of Tca8113 cells was markedly lower in NOD2-pEZ-M29 transfection group and signifi-cantly higher in NOD2-shRNA group while the apoptosis rate was significantly higher in NOD2-pEZ-M29 transfection group and sig-nificantly lower in NOD2-shRNA group.Conclusion:In Tca8113 cells NOD2 expression was positively correlated with HBD-2 ex-pression.NOD2 gene may promote the apoptosis,inhibit the proliferation of Tca8113 cells.
