摘　　要：目的:研究肺特异性X蛋白(LUNX)基因是否可作为免疫细胞浸润相关的非小细胞肺癌预后生物标志物。方法:选取衡水市人民医院2020年1月至2023年1月期间收治的280例非小细胞肺癌患者,检测其癌组织、癌旁组织LUNX基因表达量,分析LUNX基因与肿瘤微环境中免疫细胞浸润、预后生存状态的关系。结果:与癌旁组织比较,非小细胞肺癌组织LUNX基因表达量、阳性率升高,且与分化程度、淋巴结转移、肿瘤分期有关(P<0.05)。GEPIA数据库分析显示LUNX基因在其他组织中仅有少量表达或不表达,在LUAD、LUSC中表达升高(P<0.05)。LUNX基因、LUNX基因拷贝数与免疫细胞浸润水平有关(P<0.05)。生存分析显示,LUNX基因高表达与患者生存预后有关(P<0.05)。结论:LUNX基因在非小细胞肺癌组织中特异性表达,影响非小细胞肺癌免疫细胞浸润水平,导致免疫微环境失衡,是引起患者预后死亡的重要机制。因此,可作为评价免疫细胞浸润的预后生物标志物。Objective:To investigate whether the lung specific X protein(LUNX)gene can serve as a prognostic biomarker for non-small cell lung cancer related to immune cell infiltration.Methods:A total of 280 non-small cell lung cancer patients admitted to Hengshui People's Hospital from January 2020 to January 2023 were selected to detect the expression of LUNX gene in cancer tissue and adjacent tissues,and to analyze the relationship between LUNX gene and immune cell infiltration and prognosis survival status in the tumor microenvironment.Results:Compared with adjacent tissues,the expression level and positive rate of LUNX gene in non-small cell lung cancer tissue were increased,which were related to differentiation degree,lymph node metastasis and tumor staging(P<0.05).GEPIA database analysis showed that the LUNX gene was only slightly expressed or not expressed in other tissues,while its expression was elevated in LUAD and LUSC(P<0.05).The copy number of LUNX gene and LUNX gene were related to the level of immune cell infiltration(P<0.05).Survival analysis showed that high expression of the LUNX gene was associated with patient survival prognosis(P<0.05).Conclusion:The LUNX gene is specifically expressed in non-small cell lung cancer tissue,affecting the level of immune cell infiltration in non-small cell lung cancer,leading to an imbalance in the immune microenvironment,and is an important mechanism for causing patients prognostic death,which can be used as a prognostic biomarker for evaluating immune cell infiltration.
