摘要:
目的:明确宫颈癌HeLa细胞对环鸟苷酸依赖性蛋白激酶(PKG)抑制剂KT-5823的敏感性,探究KT-5823对HeLa细胞活力、凋亡和自噬的影响及机制。方法:使用不同浓度的KT-5823干预HeLa细胞24h,CCK-8、免疫印迹试验分别测定细胞活力、PKG1表达水平,进而确定后续药物刺激浓度。将HeLa细胞分为两组,即DMSO组(对照组)和KT-5823组(实验组),流式细胞术检测细胞凋亡,GFP-LC3B荧光斑点实验检测自噬斑点形成数量,实时荧光定量PCR(RT-qPCR)检测PKG1、微管相关蛋白1轻链3-Ⅱ(LC3Ⅱ)、Beclin1mRNA的表达水平,免疫印迹试验检测PKG1、自噬相关蛋白LC3Ⅱ/Ⅰ、Beclin1、自噬相关通路蛋白蛋白激酶B(Akt)、磷酸化蛋白激酶B(p-Akt)、哺乳动物雷帕霉素靶蛋白(mTOR)、磷酸化哺乳动物雷帕霉素靶蛋白(p-mTOR)、凋亡相关蛋白B细胞淋巴瘤2家族蛋白(Bcl-2)、Bcl-2相关X蛋白(Bax)、天冬氨酸特异性半胱氨酸蛋白酶3(Caspase3)蛋白的表达水平。增加自噬抑制剂SBI-0206965组观察自噬在此过程中的作用。结果:与对照组相比,实验组在3~100μmol/L刺激浓度下均可导致HeLa细胞活力降低(t=10.23~14.83,均P<0.05),PKG1蛋白表达水平逐渐降低(t=10.01~14.17,均P<0.05)。最终选取3μmol/L为刺激浓度,用于后续研究。与对照组相比,细胞凋亡增加(t=10.78,P=0.004),荧光自噬斑点数量增加(t=10.12,P=0.0005),PKG1mRNA、蛋白的表达水平降低(t=13.56,P=0.0002;t=5.461,P=0.0055)、LC3Ⅱ、Beclin1mRNA(t=8.359,P=0.0011;t=5.782,P=0.0044)、LC3Ⅱ/Ⅰ、Beclin1蛋白(t=6.924,P=0.0023;t=11.84,P=0.0003)的表达水平增加,p-Akt/Akt(t=5.194,P=0.0065)、p-mTOR/mTOR(t=12.78,P=0.0002)、Bcl-2/Bax(t=13.79,P=0.0002)的比值降低,Caspase3表达增加(t=9.341,P=0.0007)。与实验组相比,30、50、70、100μmol/L自噬抑制剂SBI-0206965组可增加细胞凋亡(t=7.616,P=0.0016;t=15.43,P=0.0001;t=11.01,P=0.0004;t=15.39,P=0.0001)。结论:PKG抑制剂KT-5823可有效抑制HeLa细胞增殖、促进细胞凋亡,同时可抑制Akt-mTOR通路诱导细胞发生自噬,且KT-5823诱导的自噬在此过程中起保护性作用,PKG可成为宫颈癌临床治疗的新靶点。
Abstract:
Objective:To determine the sensitivity of cervical cancer HeLa cells to cGMP-dependent protein kinase(PKG)inhibitor KT-5823 and explore the effects and mechanisms of KT-5823 on the viability,apoptosis and autophagy of HeLa cells. Methods:Different concentrations of KT-5823 were used to intervene HeLa cells for 24 hours. The cell viability and PKG1 expression level were detected by CCK-8 and Western blotting respectively. Then the subsequent drug stimulation concentration was determined. HeLa cells were divided into two groups,namely DMSO group(control group)and KT-5823 group(experimental group). Apoptosis was detected by flow cytometry. The number of autophagy spots was detected by GFP-LC3B fluorescence spot test. The mRNA expression level of PKG1,microtubule associated protein 1 light chain 3-Ⅱ(LC3Ⅱ)and Beclin1 was detected by real-time fluorescent quantitative PCR(RT-qPCR).The expression levels of PKG1,autophagy related protein LC3Ⅱ/Ⅰ,Beclin1,autophagy related pathway protein kinase B(Akt),phosphorylated protein kinase B(p-Akt),mammalian rapamycin target protein(mTOR),phosphorylated mammalian rapamycin target protein(p-mTOR),apoptosis related protein B-cell Lymphoma 2 family protein(Bcl-2),Bcl-2 related X protein(Bax)and Caspase 3 protein were detected by Western blotting. The autophagy inhibitor SBI-0206965 group was increased to observe the role of autophagy in this process. Results:Under the stimulation concentration of 3-100 μmol/L,the activity of HeLa cells reduced in the experimental group,compared with the control group(t=10.23-14.83,all P<0.05). The experimental group decreased PKG1 protein expression levels gradually(t=10.01-14.17,all P<0.05)compared with the control group. Final selection 3 μ mol/L was the stimulation concentration for subsequent study. Compared with the control group,apoptosis rates increased (t=10.78,P=0.004),
