| Abstract | 目的探讨IL-17A对人肝癌细胞系Hep3B、MHCC97H及MHCC97L干性的影响，以期分析IL-17A与肝癌发展之间的关系。方法选用人肝癌细胞系Hep3B、MHCC97H及MHCC97L通过体外3D成球实验分析IL-17A对其成球能力的影响，分为只含有普通培养液的对照组和加50ng／mlIL-17A的实验组。采用实时无标记动态细胞分析技术检测IL-17A对成球能力增强的肝癌细胞增殖及迁移的影响；采用实时定量PCR检测分析IL-17A对成球能力增强的肝癌细胞所表达的IL-17A受体IL-17RA、IL-17RC以及干性相关基因SOX2、NANOG、OCT4、BMII的mRNA表达的影响；通过WesternBlot检测上皮-间质转换（EMT）相关蛋白E-钙黏蛋白（E—cadherin）、N-钙黏蛋白（N—cadherin）、波形蛋白（vimentin）的表达。计量资料组间比较采用t检验。结果在存在50ng／mlIL-17A及接种细胞数均为500个的条件下，Hep3B肝癌细胞的成球数目显著增加[由（113．0±10．3）个增加至（180．0±7．2）个，t=5．533，P〈0．001]，MHCC97H（t：1．087，P=0．325）及MHCC97L（t=0．279，P=0．785）的成球数目无明显变化。对于成球数目增加的Hep3B细胞，进一步分析发现IL-17A促进了其增殖和迁移。并且，加入50ng／mlIL-17A后，IL-17A受体IL-17RA及IL-17RCmRNA的表达随着作用时间的增加而升高；加入50ng／ml IL-17A作用后，Hep3B细胞的干性相关基因SOX2（t=4．749，P：0．042）、NANOG（t=19．600，P=0．003）、OCT4（t：37．310，P〈0．001）和BM11（t=16．810，P=0．004）的mRNA表达均显著上调；通过Westernblot检测发现EMT相关上皮源性标志物E—Cadherin表达无明显的降低趋势，vimentin表达未出现稳定升高。间质性标志物N—Cadherin在50rig／m1IL-17A作用48h时后其mRNA表达增加（t=17．620，P=0．036）。结论IL-17A在一定程度上增强了Hep3B肝癌细胞的干性。 |

| Abstract_FL | Objective To investigate the effect of interleukin-17A (IL-17A) on stemness of human hepatoma cell lines Hep 3B,MHCC97H,and MHCC97L and the association between IL-17A and the progression of liver cancer.Methods Human hepatoma cell lines Hep 3B,MHCC97H,and MHCC97L were selected,and in vitro 3D sphere formation assay was used to analyze the effect of IL-17A on sphere formation ability.The control group with common culture solution and the experimental group with 50 ng/ml IL-17A were established.Real-time cellular analysis was used to determine the effect of IL-17A on the proliferation and migration of hepatoma cells with enhanced sphere formation ability;quantitative real-time PCR was used to measure the changes in the mRNA expression of IL-17A receptors IL-17RA and IL-17RC and stemness-related genes SOX2,NANOG,OCT4,and BMI1 in hepatoma ceils with enhanced sphere formation ability;Western blot was used to measure the expression of epithelial-mesenchymal transition-related proteins E-cadherin,N-cadherin,and vimentin.The t-test was used for comparison of continuous doota betwwen groups.Results With the presence of 50 ng/ml IL-17A and 500 inoculated cells,Hep 3 B cells had a significant increase in the number of spheres formed (113.0 ± 10.3 vs 180.0 ± 7.2,t =5.533,P ＜ 0.001),while MHCC97H and MHCC97L cells showed no significant changes (t =1.087 and 0.279,P =0.325 and 0.785).The analysis showed that IL-17A promoted the proliferation and migration of Hep 3B cells with an increased number of spheres formed.After the addition of 50 ng/ml IL-17A,there was an increase in the mRNA expression of IL-17A receptors IL-17RA and IL-17RC over the time of treatment;Hep 3 B cells showed significant increases in the mRNA expression of stemness-related genes SOX2 (t =4.749,P =0.042),NANOG (t =19.600,P =0.003),OCT4 (t =37.310,P ＜ 0.001),and BMI1 (t =16.810,P =0.004).Western blot showed no significant change in the expression of the epithelium-derived marker E-Cadherin;there was an increase in the expression of the interstitial marker N-cadherin after the treatment with 50 ng/ml IL-17A for 48 hours (t =17.620,P =0.036);there was no significant change in the expression of vimentin.Conclusion To a certain degree,IL-17A enhances the stemness of Hep 3B hepatoma cells. |
