Lung adenocarcinoma (LUAD) is the most common subtype of lung cancer with a high mortality disease which has been positioned the first and second cancer morbidity of men and women in China, separately. Our study was to assess the prognostic meaningful of ubiquitin conjugating enzyme E2 T (UBE2T) expression in LUAD dependent on data acquired from The Cancer Genome Atlas (TCGA) and so as to increase further knowledge into the biological pathways involved in LUAD pathogenesis related to UBE2T.Information on gene expression and comparing clinical data were recognized and downloaded from TCGA. Gene set enrichment analysis (GSEA) created an arranged list of all genes s indicated by their connection with UBE2T expression.Our study cohort included 265 (54.5%) female and 221 (36.0%) male patients. The scatter plot and paired plot showed the difference of UBE2T expression between normal and tumor samples (P < .01). Overall survival (OS) analysis demonstrated that LUAD with UBE2T-high had a more terrible prognosis than that with UBE2T-low (P < .01). Multivariate analysis with the cox proportional hazards model indicated that the expression of UBE2T (hazard ratio [HR]: 1.28; 95% Confidence Interval (CI): 1.06-1.56; P = .011) and stage (HR: 2.02; 95% CI: 1.27-3.21; P = .003) were independent prognostic factors for patients with LUAD. The GSEA results showed that cell cycle, DNA replication, RNA degradation, oxidative phosphorylation, pathogenic Escherichia coli infection, citrate cycle tricarboxylic acid cycle, Alzheimer's disease, P53 signaling pathway, and purine metabolism are differentially enriched in UBE2T high expression phenotype.Our study found that the expression of UBE2T was significantly increased in LUAD patients and associated with several clinical features. UBE2T may be a potentially useful prognostic molecular biomarker of bad survival in LUAD, while further experimental ought to be performed to demonstrate the biologic effect of UBE2T.
