目的研究Akt1在环氧合酶2抑制剂NS398抑制宫颈癌Hela细胞增殖过程中的作用。方法以不同浓度的NS398或Akt1选择性激动剂IGF-1与NS398共同处理Hela细胞,采用噻唑蓝(MTT)比色法分析细胞生长抑制率,Western blotting免疫印迹技术分别检测Akt1蛋白表达的变化。结果与对照组比较,不同浓度的NS398处理Hela细胞后,细胞生长抑制率(IR)增加(P<0.05);NS398呈浓度和时间依赖性下调Hela细胞Akt1蛋白质的表达(P<0.05);与单独用NS398组比较,Akt1激动剂与NS398共同处理细胞后,细胞IR值逐渐下降,并且其作用呈浓度依赖和时间依赖性(P<0.05)。结论NS398呈剂量和时间依赖性抑制Hela细胞的增殖,其作用机制可能与下调Akt1蛋白的表达有关。 |

ObjectiveInvestigate to the effect of Akt1 on Inhibition of Cervical Cance Hela Cell Proliferation by Cyclooxygenase-2 inhibitor.MethodsHela cells were treated with NS398 and (or) Akt1 agonist IGF-1,then the growth inhibitory rate (IR) of cell was evaluated by MTT assay.The expressions of Akt1 were detected by Western Blotting.ResultsNS398 significantly increase the IR of Hela cells and down-regulate the Akt1 protein expression(P<0.05).Akt1 agonist IGF-1 decreased the IR of Hela cells compared with only treated with NS398 groups.These effects are dose-dependent manner.ConclusionNS398 inhibits Hela cell growth in a dose-dependent and time-dependent manners,and the mechanism may be related to down-regulate the expressions of Akt1. |
