摘要: 目的

通过生物信息学方法探讨硫氧还蛋白结构域11 (TXNDC11)在泛癌预后分析中的作用及与肿瘤免疫细胞浸润的关系,阐明其对肿瘤的预后评估价值。

方法

采用ONCOMINE和TIMER数据库综合分析TXNDC11 mRNA和蛋白在肿瘤组织及相对应癌旁正常组织中的表达;采用临床蛋白质组肿瘤分析协作组(CPTAC)数据库分析TXNDC11蛋白在肿瘤组织和正常组织间表达的差异;采用基因表达谱交互分析网站(GEPIA)分析TXNDC11表达与泛癌分期之间的关系;采用Kaplan-Meier Plotter在线网站分析TXNDC11表达与泛癌患者生存预后的关系;采用TIMER数据库分析各种肿瘤组织中TXNDC11蛋白表达与肿瘤免疫浸润细胞之间的相关性;采用SangerBox数据库分析TXNDC11蛋白与免疫检查点的关系。

结果

ONCOMINE数据库分析,与癌旁正常组织比较,结肠癌(COAD)、胃腺癌(STAD)和肉瘤(SARC)组织中TXNDC11 mRNA表达水平明显降低(P<0.05),而乳腺癌(BRCA)、食管癌(ESCA)、肾嫌色细胞癌(KICH)和胰腺癌(PAAD)组织中TXNDC11 mRNA表达水平明显升高(P<0.01)。TIMER数据库分析,BRCA、胆管癌(CHOL)、ESCA、胶质母细胞瘤(GBM)、头颈鳞状细胞癌(HNSC)和前列腺癌(PRAD)组织中TXNDC11蛋白表达水平升高,COAD、肾乳头状细胞癌(KIRP)、肺腺癌(LUAD)、肺鳞状细胞癌(LUSC)、嗜铬细胞瘤和副神经节瘤(PCPG)、直肠腺癌(READ)和甲状腺癌(THCA)组织中TXNDC11呈明显低表达。CPTAC数据库分析,肾透明细胞癌(KIRC)和子宫内膜癌(UCEC)组织中TXNDC11蛋白表达水平明显高于癌旁正常组织(P<0.01),而BRCA、卵巢癌(OV)和COAD组织中TXNDC11蛋白表达水平明显低于癌旁正常组织(P<0.05或P<0.01)。GEPIA数据库分析,TXNDC11表达水平与LUAD、卵巢浆液性囊腺癌、THCA和UCEC患者的临床病理分期有密切关联(P<0.05)。Kaplan-Meier Plotter数据库分析,膀胱尿路上皮癌(BLCA)(HR=0.71,P=0.024)、BRCA(HR=0.68,P=0.021)、ESCA(HR=0.39,P=0.005 1)、HNSC(HR=0.72,P=0.026)、KIRC(HR=0.41,P=0.002 6)、LUAD(HR=0.53,P<0.01)、READ(HR=0.34,P=0.014)、SARC(HR=0.61,P=0.016)、胸腺癌(THYM)(HR=0.14,P=0.004 2)、THCA(HR=0.35,P=0.043)和UCEC(HR=0.36,P<0.01)组织中TXNDC11的高表达与肿瘤患者的良好预后有关联。TIMER数据库分析,TXNDC11表达与22种肿瘤组织中B细胞浸润水平有相关性(P<0.05),TXNDC11表达与16种肿瘤组织中CD4+T淋巴细胞浸润水平、25种肿瘤组织中CD8+T淋巴细胞浸润水平、22种肿瘤组织中中性粒细胞浸润水平、22种肿瘤组织中巨噬细胞浸润水平和23种肿瘤组织中树突状细胞浸润水平有明显相关性(P<0.05);TXNDC11表达与COAD、LUSC、HNSC、SARC和皮肤黑色素瘤(SKCM)的免疫细胞具有明显相关性(P<0.01)。SangerBox数据库分析,TXNDC11在多种肿瘤组织中与多个免疫检查点基因表达水平有明显相关性(P<0.05)。

结论

泛癌分析中,TXNDC11在多种肿瘤组织中普遍低表达,且TXNDC11与多种肿瘤患者的预后生存有密切关联。TXNDC11可作为一个重要的肿瘤预后预测因子,并在一定程度上调节多种肿瘤的免疫反应。

Abstract: Objective

To explore the prognostic value of thioredoxin domain containing 11(TXNDC11) in pan-cancer and its relationship with tumor immune cell infiltration by bioinformatics, and to clarify its evaluation value in tumor prognosis.

Methods

The expressions of TXNDC11 mRNA and protein in tumor tissue and corresponding paracancerous tissue were analyzed using ONCOMINE database and TIMER database. The expression difference of TXNDC11 protein between tumor tissue and normal tissue was analyzed by Clinical Proteomic Tumor Analysis Consortium (CPTAC) database. The correlations between the TXNDC11 protein expression and pan-cancer stages were analyzed using Gene Expression Profile Interactive Analysis (GEPIA) database. The relationship between TXNDC11 expression and survival prognosis of patients with pan-cancer was analyzed using online Kaplan Meier plotter. The correlations between the TXNDC11 protein expression and tumor- infiltrating immune cells were studied by TIMER database. The relationship between TXNDC11 protein and immune checkpoint was analyzed using Sangerbox database.

Results

The ONCOMINE database analysis results showed that compared with paracancerous normal tissue, the expression levels of TXNDC11 mRNA in colon adenocarcinoma(COAD),stomach adenocarcinoma(STAD) and sarcoma(SARC) tissues were decreased significantly (P<0.01), while the expression levels of TXNDC11 mRNA in breast cancer(BRCA),esophageal carcinoma(ESCA), kidney chromophobe(KICH) and pancreatic adenocarcinoma(PAAD) tissues were increased (P<0.01). In TIMER database,the expression levels of TXNDC11 protein in BRCA, cholangiocarcinoma(CHOL), glioblastoma multiforme(GBM), head and neck squamous cell carcinoma(HNSC) and prostate adenocarcinoma(PRAD) tissues were increased,and the TXNDC11 protein expression levels in COAD,kidney renal papillary cell carcinoma(KIRP),lung adenocarcinoma(LUAD), lung squamous cell carcinoma(LUSC),pheochromocytoma and paraganglioma(PCPG),rectum adenocarcinoma(READ) and thyroid carcinoma(THCA) tissues were signifcantly decreased.The CPTAC database analysis showed that the protein expression levels of TXNDC11 in kidney renal clear cell carcinoma(KIRC) and uterine corpus endometrial carcinoma(UCEC) were significantly higher than those in normal tissue (P<0.01),but theexpression levels of TXNDC11 protein in BRCA,ovarian cancer(OV) and COAD tissues were lower than those in normal tissue (P<0.05).The expression level of TXNDC11 protein in GEPIA database was closely related to the clinical characteristics and pathological stages of LUAD,ovarian serous cystadenocarcinoma, THCA and UCEC patients(P<0.05).In Kaplan Meier plotter database, the high expressions of TXNDC11 in bladder urothelial carcinoma (BLCA) (HR=0.71,P=0.024), BRCA(HR=0.68, P=0.021), ESCA (HR=0.39,P=0.005 1),HNSC (HR=0.72,P=0.026), KIRC(HR=0.41,P=0.002 6),LUAD(HR=0.53,P<0.01),READ(HR=0.34,P=0.014),SARC(HR=0.61,P=0.016),thymoma (THYM)(HR=0.14, P=0.004 2),THCA(HR=0.35,P=0.043) and UCEC(HR = 0.36, P<0.01) tissues were associated with the better prognosis of the patients. The TIMER database analysis results showed that TXNDC11 was significantly correlated with the levels of B cell infiltration in 22 kinds of tumor tissues(P<0.05);in addition, the expression of TXNDC11 was significantly correlated with the infiltration levels of CD4 + T cells in 16 kinds of tumor tissues,CD8 +T cells in 25 kinds of tumor tissues, neutrophils in 22 kinds of tumor tissues,macrophages in 22 kinds of tumor tissues and the dendritic cells in 23 kinds of tumor tissues (P<0.05);TXNDC11 protein expression was significantly correlated with immune cells in COAD, LUSC, HNSC, SARC and skin melanoma (SKCM)(P<0.01).The Sangerbox database analysis results showed that TXNDC11 protein was significantly correlated with the expression levels of multiple immune checkpoint genes in a variety of tumor tissues (P<0.05).

Conclusion

In pan-cancer analysis, TXNDC11 is generally low expressed in a variety of tumor tissue, and TXNDC11 is significantly correlated with the prognosis and survival of patients with a few of tumors. Therefore, TXNDC11 can be used as an important predictor of tumor prognosis and regulate the various tumor-related immune responses in a certain degree.
