Abstract: 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 1 161 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.
