摘要:

[摘要] 目的:基于肿瘤数据库分析恶性胸膜间皮瘤(MPM)患者组织中血小板反应蛋白2THBS2)基因mRNA的表达水平及临床意义。方法:通过Oncomine数据库分析MPM组织与正常组织中THBS2基因mRNA的表达差异;利用TCGA数据库和UALCAN数据库分析THBS2基因mRNA表达量与MPM患者的临床病理参数相关性;构建Kaplan-Meier生存模型分析THBS2基因表达量对于MPM患者的预后影响;构建COX回归模型探究影响MPM患者预后的独立危险因素;使用GEPIA2数据库分析THBS2基因与MPM肿瘤标志物基因和THBS基因家族其他成员表达的相关性。结果:THBS2基因在MPM组织中的表达量显著高于正常胸膜组织和正常肺组织(P<0.05)。MPM组织中THBS2基因表达量在N0N3分期、N1N3分期、N2N3分期之间差异均具有统计学意义(P<0.05)。THBS2基因高表达与肉瘤型和双相混合型肿瘤是导致MPM患者预后不良的独立危险因素。MPM肿瘤标志物CDH11基因与THBS2基因的表达呈显著正相关,CALB2MSLN基因与THBS2基因的表达呈显著负相关。此外,THBS1THBS3THBS4基因表达与THBS2基因的表达均呈显著正相关。结论:THBS2基因在不同类型肿瘤中表达各异,在人MPM组织中表达水平升高,且表达量与患者的预后负相关,THBS2基因可作为MPM潜在的初步诊断和判断预后的标志物。

Abstract:

Abstract ObjectiveTo analyze the expression level and clinical significance of thrombospondin-2 THBS2 gene mRNA in patients with malignant pleural mesothelioma MPM based on tumor databases. Methods The difference of THBS2 mRNA expression between MPM and normal tissues was analyzed by Oncomine database and the correlation between THBS2 mRNA expression and clinicopathological parameters of MPM patients was analyzed by TCGA database and UALCAN database. Kaplan- Meier survival model was constructed to analyze the prognostic effect of THBS2 gene expression on MPM patients COX regression model was constructed to explore the independent risk factors affecting the prognosis of MPM patients GEPIA2 database was used to analyze the correlation between THBS2 gene and the expression of tumor marker gene and other members of THBS gene family in MPM patients. ResultsThe expression of THBS2 gene in MPM tissues was significantly higher than that in normal pleural tissues and normal lung tissues. There were significant differences in THBS2 gene expression between N0 and N3 N1 and N3 N2 and N3 in MPM tissues. The high expression of THBS2 gene and sarcomatous and biphasic mixed tumors are independent risk factors for poor prognosis in patients with MPM. The expression of CDH11 was positively correlated with THBS2 while CALB2 and MSLN were negatively correlated with THBS2. In addition the expression of THBS1 THBS3 THBS4 was positively correlated with that of THBS2. ConclusionTHBS2 is expressed differently in different types of cancer. Through the analysis of public database it is found that the expression level of THBS2 gene is increased in human MPM tissue and the expression of THBS2 is negatively correlated with the prognosis of patients. Therefore THBS2 can be used as a potential marker for the preliminary diagnosis and prognosis of MPM.
