Abstract：[Abstract]Objective: To investigate the expression levels of regulatory factor X5(RFX5) in digestive system neoplasms. Methods: RFX5 mRNA expression levels were determined by analyzing the RNAseq data from the the Cancer Genome Atlas(TCGA) database. By using tissue microarray technology and immunohistochemical staining, RFX5 protein expression was confirmed in six different types of digestive system tumors(esophageal, stomach, colon, rectal, liver and pancreatic cancers) and corresponding nontumor normal tissues. Results: RFX5 mRNA and protein levels were upregulated in six malignancies, and the altitudes increase more significantly in stomach adenocarcinoma and hepatocellular carcinoma than other cancer types. Conclusion: Expressions of RFX5 mRNA and protein were both elevated in digestive system neoplasms.
