摘要:
目的探讨苦参碱通过Pink1/Parkin途径抑制线粒体途径促进肝癌细胞凋亡的作用机制。 方法培养人源性肝癌细胞系HepG2,按照干预条件分成对照组、Pink1/Parkin信号通路抑制剂3-MA抑制剂组及0.5、1.0 g/L苦参碱处理组,采用反转录-聚合酶链反应(reverse transcription-polymerase chain reaction,RT-PCR)、免疫蛋白印迹(Western Blot)和免疫荧光检测Pink1和Parkin以及凋亡信号蛋白Bcl-2、Bad、Bax、Caspase-3、Caspase-6和Caspase-9等表达,应用CCK-8试剂盒检测细胞增殖能力、Transwell试剂盒检测细胞侵袭能力、AV-PI试剂盒检测细胞凋亡率。 结果RT-PCR、Western Blot结果显示:0.5和1.0 g/L苦参碱处理组Pink1 含量低于对照组,差异具有统计学意义(P<0.05);1.0 g/L处理组Pink1 mRNA含量低于0.5 g/L处理组,差异具有统计学意义(P<0.05);0.5和1.0 g/L苦参碱处理组Pink1 mRNA含量低于抑制剂组,差异具有统计学意义(P<0.05);对照组Pink1 mRNA含量与抑制剂组比较差异无统计学意义(P>0.05)。Parkin和Bcl-2的表达趋势与Pink1相同,而凋亡相关因子Bad、Bax、Caspase-3、Caspase-6和Caspase-9等的表达与Pink1相反。CCK-8、Transwell检测结果显示:0.5和1.0 g/L苦参碱处理组细胞增殖能力与细胞侵袭能力均低于对照组,差异具有统计学意义(P<0.05);对照组细胞增殖能力、侵袭能力与抑制剂组比较差异无统计学意义(P>0.05)。AV-PI结果显示:0.5和1.0 g/L苦参碱处理组细胞侵袭能力低于对照组,差异具有统计学意义(P<0.05);对照组细胞侵袭能力与抑制剂组比较差异无统计学意义(P>0.05)。 结论苦参碱可以抑制肝癌细胞的增殖和侵袭能力,促进肝癌细胞凋亡,并且具有剂量依赖性。
Abstract:
ObjectiveTo explore the mechanism of matrine inhibiting mitochondrial pathway and promoting apoptosis of hepatoma cells through Pink1/Parkin pathway. MethodsAfter culturing human hepatoma cell line HepG2, the cells were divided into the control group, Pink1/Parkin signaling pathway inhibitor 3-MA inhibitor group and matrine processing groups of 0.5 g/L and 1.0 g/L according to the intervention conditions, RT-PCR, Western Blot and immunofluorescence were adopted to detect the contents of Pink1 and Parkin, the expressions of apoptosis signal proteins Bcl-2, Bad, Bax, Caspase-3, Caspase-6, Caspase-9 and others, CCK-8 test kit was applied to measure cell proliferation ability, Transwell test kit to determine cell invasion ability,AV-PI test kit to measure cell apoptosis rate. ResultsThe results of RT-PCR, Western Blot displayed that the contents of Pink1 in the matrine processing groups of 0.5 and 1.0 g/L were lower than these of the control group, and the difference had statistical meaning (P<0.05); the contents of Pink1 mRNA in 1.0 g/L matrine processing group were lower than these of 0.5 g/L matrine processing group, and the difference had statistical meaning (P<0.05); the contents of Pink1 mRNA in matrine processing groups of 0.5 and 1.0 g/L were lower than these in inhibitor group, and the difference was statistically significant (P<0.05); the difference had no statistical meaning when the contents of Pink1 mRNA in the control group were compared with these in inhibitor group (P>0.05), expression trend of Parkin and Bcl-2 was the same as that of Pink1, while the apoptosis related factors Bad, Bax, Caspase-3, Caspase-6 and Caspase-9 were opposite to Pink1. The results of CCK-8 and Transwell results showed that the cell proliferation ability and cell apoptosis rate of matrineprocessing groups of 0.5 g/L and 1.0 g/L were lower than these of the control group, and the difference had statistical meaning (P<0.05). The difference had no statistical meaning when cell proliferation ability and invasion ability of the control group were compared with these of the inhibitor group (P>0.05). AV-PI results showed that the invasion ability of matrine processing groups of 0.5 g/L and 1.0 g/L was lower than that of the control group, and the difference showed statistical meaning (P<0.05); there was no statistical difference in the comparison of invasion ability between the control group and the inhibitor group (P>0.05). ConclusionMatrine could inhibit the proliferation and invasion ability of hepatoma cells, promote the apoptosis of hepatoma cells in dose-dependent manner.
