摘要: 目的

探讨小豆蔻明(CAR)对宫颈癌HeLa细胞增殖的影响,并阐明其可能的作用机制。

方法

宫颈癌HeLa细胞分为对照组(不进行任何处理)和不同浓度(10、20和40 μmol?L-1)CAR组(给予10、20和40 μmol?L-1CAR)。CCK-8法检测处理24、48和72 h后各组宫颈癌HeLa细胞活性,菌落形成实验检测各组宫颈癌HeLa细胞克隆形成数,Hoechst33258染色观察各组宫颈癌HeLa细胞凋亡形态表现,Western blotting法检测各组宫颈癌HeLa细胞中B细胞淋巴瘤2(Bcl-2)、Bcl-2相关X蛋白(Bax)、磷酸化磷脂酰肌醇3激酶(p-PI3K)和磷酸化蛋白激酶B(p-AKT)蛋白表达水平。

结果

与对照组比较,各时间点不同浓度CAR组HeLa细胞活性明显降低(24 h:P=0.011 8; 48 h:P=0.000 4; 72 h:P=0.002 2);与对照组比较,不同浓度CAR组HeLa细胞克隆形成数均明显降低(P<0.01);与对照组比较,不同浓度CAR组HeLa细胞出现明显核聚集、皱缩或碎裂的凋亡形态;与对照组比较,不同浓度CAR组HeLa细胞中Bcl-2、p-PI3K(P=0.011 8)和p-AKT(P=0.034 9)蛋白表达水平明显降低,Bax蛋白表达水平明显升高,Bcl-2/Bax比值明显降低(P<0.01)。

结论

CAR通过调控PI3K/AKT信号通路诱导凋亡并抑制HeLa细胞增殖。

Abstract: Objective

To investigate the effect of cardamom (CAR) on the proliferation of the cervical cancer HeLa cells, and to clarify its possible mechanism.

Methods

The cervical cancer HeLa cells were divided into control group(given no treatment) and different concentrations (10, 20,and 40 μmol?L-1) of CAR groups(given different concerntrations of CAR). CCK-8 method was used to detect the viabilities of the cervical cancer HeLa cells in various groups at 24, 48,and 72 h after treatment; the colony formation experiment was used to detect the clone formation number of the cervical cancer HeLa cells in various groups;and the apoptotic morphology of cervical cancer HeLa cells in various groups was observed by Hoechst33258 staining; Western blotting method was used to detect the expression levels of B-cell lymphoma-2(Bcl-2),Bcl-2 associated X protein(Bax),phosphorylated-phosphatidylinositol 3-kinase(p-PI3K),and phosphorylated-protein kinase B(p-AKT)proteins in the HeLa cells in various groups.

Results

Compared with control group, the viabilities of the cervical cancer HeLa cells in different concentrations of CAR groups after treated for different time were decreased (24 h:P=0.011 8; 48 h:P=0.000 4; 72 h:P=0.002 2);compared with control group, the clone formation number of HeLa cells in different concentrations of CAR groups was significantly decreased (P<0.01);compared with control group, the apoptotic morphology of HeLa cells in different concentrations of CAR groups showed as nuclear aggregation, shrinkage or fragmentation; compared with control group, the expression levels of Bcl2, p-PI3K(P=0.011 8), and p-AKT(P=0.034 9) proteins in the cervical cancer HeLa cells in different concentrations of CAR groups were significantly decresed, while the levels of Bax protein were increased, and the ratios of Bcl-2/Bax were decreased(P<0.01).

Conclusion

CAR can induce the apoptosis and inhibit the proliferation of cervical cancer HeLa cells by regulating the PI3K/AKT signaling pathway.
