Title: Trim47 overexpression correlates with poor prognosis in gastric cancer
Author: YuJian Xia, ZheWei Wei, WeiBin Huang, XiaoJing Wei, YuLong He

Abstract: Trim47 is a member of the tripartite motif (TRIM) family that participates in many pathophysiological processes. However, the expression pattern and biological functions of Trim47 in gastric cancer (GC) remain unclear. The present study aimed to further explore the clinicopathological significance and potential prognostic role of Trim47 expression in GC. Therefore, in this study, Trim47 mRNA level was investigated in the Cancer Genome Atlas (TCGA) and Oncomine database in GC. We detected Trim47 mRNA and protein expression levels in GC and paired adjacent normal tissues. Kaplan-Meier method and Cox proportional hazard regression models were performed to analyze the survival of patients and prognostic factors. A gene set enrichment analysis (GSEA) was performed to determine the mechanism of Trim47 in GC. Our results indicated that Trim47 mRNA expression in GC tissues was significantly higher than adjacent normal tissues, as was Trim47 protein expression. Trim47 overexpression in GC tissues was significantly associated with tumor differentiation, T stage, N stage, M stage and TNM stage. Kaplan-Meier analyses showed that high Trim47 expression was associated with worse overall survival (OS) and disease-free survival (DFS) in GC patients. Multivariate analysis confirmed that Trim47 expression was an independent prognostic factor for GC patients. Bioinformatics analysis and western blot indicated Trim47 might regulate GC though NF-kB, EMT, hypoxia and apoptosis signaling pathway in GC. Our results show that Trim47 has potential to serve as a novel prognostic biomarker in GC patients.
