[ENTPD5 gene is highly expressed in epithelial ovarian cancer: analysis based on Oncomine database and
1The first clinical college of Southern Medical University, Guangzhou 510515, China.
Objective:
To investigate the expression of ENTPD5 in epithelial ovarian cancer and explore its clinical implications.
Objective:
The expression level of ENTPD5 in epithelial ovarian cancer was analyzed based on data from Oncomine and TCGA databases. The relationship between the expression level of ENTPD5 and clinical characteristics of the patients was analyzed using UALCAN database. Gene enrichment analysis (GSEA) was performed to explore the possible role of ENTPD5 in the occurrence and progression of epithelial ovarian cancer. CIBERSORT package was used to analyze the relationship between the expression of ENTPD5 and immune infiltration. The expression patterns of ENTPD5 were verified in 23 epithelial ovarian cancer tissues and 15 normal ovarian tissues using RT-qPCR and Western blotting; the expression of ENTPD5 protein was also detected immunohistochemically in 50 paraffin-embedded samples of epithelial ovarian cancer and 6 normal ovarian tissues.
Objective:
Analysis of Oncomine and TCGA databases showed that the expression of ENTPD5 was significantly higher in epithelial ovarian cancer tissues than in normal ovarian tissues (P < 0.05), and its expression level was negatively correlated with the survival rate of the patients (P < 0.05). Data from UALCAN database showed that the expression level of ENTPD5 was related with the age of patients. The results of GSEA suggested that ENTPD5 was involved in ABC transporter, WNT signaling pathway and insulin signaling, and the expression of ENTPD5 was negatively correlated with the contents of NK cells, mast cells and eosinophils (P < 0.05). In clinical samples of epithelial ovarian cancer tissues, the expression of ENTPD5 was significantly higher than that in normal ovarian tissues at both the mRNA (P < 0.01) and protein (P < 0.05) levels. The paraffinembedded samples also showed significantly higher expressions of ENTPD5 in epithelial ovarian cancer than in normal ovarian tissues (P < 0.05).
Objective:
ENTPD5 is highly expressed in epithelial ovarian cancer, which may promote the occurrence and progression of epithelial ovarian cancer by participating in multiple functional processes and cellular immune infiltration.

When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
