摘　　要：目的研究非小细胞肺癌(Non-small cell lung cancer,NSCLC)患者癌症高甲基化1(Hypermethylated in cancer 1,HIC1)表达水平与总生存期(Overall Survival,OS)之间的相关性。方法本研究从Kaplan-Meier Plotter(KM plotter)数据库中收集有详细的病理类型、临床分期和治疗信息,且具备完整的RNA-seq或基因芯片数据的患者,NSCLC共计2166例,其中包括1161例腺癌患者和780例鳞状细胞癌患者。利用Kaplan-Meier Plotter在线数据库进行Cox回归分析,多因素Cox回归分析校正了如下混杂因素:性别、吸烟史、临床分期、手术切缘状态、化疗和放疗情况。分析了2166例NSCLC患者的HIC1 mRNA表达水平和OS间的关系。采用Transwell迁移实验检测敲减HIC1基因后对人肺腺癌细胞株(PC9)细胞迁移能力的影响。结果接受化疗的肺腺癌患者中,HIC1高表达显著延长了患者OS(HR=0.54,95%CI:0.34~0.86,P=0.009),死亡风险降低了46%。Transwell细胞迁移实验结果发现HIC1低表达组PC9细胞迁移能力升高(P<0.001)。结论HIC1 mRNA表达可能成为接受化疗的NSCLC患者重要的预后指标。Objective The aim of this study was to investigate the correlation between the expression of hypermethylated in cancer 1(HIC1)and overall survival(OS)in non-small cell lung cancer(NSCLC)patients.Methods A total of 2,166 patients with NSCLC,including 1161 patients with adenocarcinoma and 780 patients with squamous cell carcinoma,were collected from the Kaplan-Meier plotter plus(KM plotter)database with detailed pathological type,clinical stage,treatment information,and complete RNA-seq or Gene chip data.Univariate Cox proportional risk regression analysis was performed using KM plotter online database.Multivariate Cox regression analysis corrected for the following confounding factors:gender,smoking history,clinical stage,surgical margin status,chemotherapy and radiotherapy.The relationship between the expression of HIC1 mRNA and OS in 2,166 NSCLC patients was analyzed.Transwell migration assay was used to detect the effect of knockdown HIC1 gene on the migration ability of PC9 cells(lung adenocarcinoma cell line).Results In lung adenocarcinoma patients receiving chemotherapy,the high expression of HIC1 significantly prolonged the OS(HR=0.54,95%CI:0.34-0.86,P=0.009),and reduced the risk of death by 46%.Transwell cell migration assay showed that the migration ability in PC9 cells in the low expression of HIC1 was increased(P<0.001).Conclusion The expression of HIC1 mRNA may be an important prognostic predictor for NSCLC patients receiving chemotherapy.
