Effect of lobaplatin on proliferation and apoptosis of hepatocellular carcinoma HepG2 cells and related mechanism of action

Department of Medical Oncology, Zhangzhou Hospital Affiliated to Fujian Medical University

摘要

摘要: 目的在体外细胞中研究洛铂对肝癌HepG2细胞在增殖、凋亡方面的作用及其机制。方法将HepG2细胞分为洛铂组（增殖实验:5、10、15μmol/L组;凋亡实验:10μmol/L;侵袭实验:4μg/ml）和对照组（不加药物）。利用CCK8法和流式细胞术分别检测2组HepG2细胞的增殖和凋亡情况。通过Western Blot初步检测2组细胞中增殖、凋亡相关蛋白NF-κB、Bcl-2、Bax、Bid、Puma、Caspase-3的表达变化。增殖实验采用双因素方差分析,凋亡实验采用χ2检验,侵袭实验采用t检验。结果在作用于细胞24、48、72 h后,对照组与实验组细胞生长增殖抑制率差异有统计学意义（F=273.5,P<0.01）,同一时间不同浓度间、同一浓度不同时间差异均有统计学意义（F分别为1857、1365,P值均<0.01）。2组间细胞凋亡率比较差异有统计学意义（χ2=1821,P<0.001）。实验组HepG2细胞中穿透Transwell小室的细胞数少于对照组（21.30±2.74 vs 45.00±4.26,t=11.89,P<0.001）。洛铂组HepG2细胞...

Abstract: Objective To investigate the effect of lobaplatin on the proliferation and apoptosis of hepatocellular carcinoma (HCC) HepG2 cells in vitro and related mechanism of action.Methods HepG2 cells were divided into lobaplatin group (proliferation assay:5 μmol/L, 10 μmol/L, and 15 μmol/L; apoptosis assay:10 μmol/L; invasion assay:4 μg/ml) and control group (no drug was added) .CCK-8 assay and flow cytometry were used to measure the proliferation and apoptosis of HepG2 cells.Western Blot was used to measure the change in the expression of NF-κB, Bcl-2, Bax, Bid, Puma, and caspase-3 proteins involved in proliferation and apoptosis.A two-way analysis of variance was used for proliferation assay, the chi-square test was used for apoptosis assay, and the t-test was used for invasion assay.Results After intervention for 24, 48, and 72 hours, there was a significant difference in proliferation inhibition rate between the two groups (F = 273.5, P < 0.01) ; there was also a significant difference between different concentration groups at the same time point (F =1857, P < 0.01) , and all the concentration groups showed a significant change over time (F = 1365, P < 0.01) .As for apoptosis, there was a significant difference in apoptosis rate between the two groups (χ2= 1821, P < 0.001) .As for invasion ability, compared with the control group, the lobaplatin group had a significantly lower number of cells passing through the Transwell chamber (21.30 ± 2.74 vs 45.00± 4.26, t = 11.89, P < 0.001) .As for proteins, the lobaplatin group had a significant reduction in the expression of Bcl-2 and significant increases in the expression of NF-κB, Bax, Puma, and caspase-3.Conclusion Lobaplatin exerts a certain effect on the proliferation and apoptosis of HCC HepG2 cells by affecting the proteins involved in proliferation and apoptosis, but further studies are needed due to complex signaling pathways in cells.
