This study comprehensively assessed the expression and clinical relevance of ENPP2 in hepatocellular carcinoma (HCC). ENPP2 expression was found to be associated with clinical stage and is a significant prognostic factor for worse outcomes in HCC patients. The diagnostic value of ENPP2 expression in HCC was confirmed, and gene set enrichment analysis identified pathways enriched in HCC patients with high ENPP2 expression. Overall, ENPP2 is highly expressed in HCC and is a potential independent molecular marker for the diagnosis and prognosis of HCC.
Ectonucleotide pyrophosphatase/phosphodiesterase 2 (ENPP2) has been identified as a potential biomarker in lung and prostate cancers; however, its expression and clinical relevance in hepatocellular carcinoma (HCC) remain incompletely understood. This study comprehensively assessed ENPP2 expression in pan-cancer using bioinformatics. We analyzed the expression of ENPP2 mRNA in primary liver cancer and adjacent tissues of patients with HCC using data from the TCGA database. Cox regression and Kaplan-Meier methods were used to identify clinicopathological factors associated with survival, and the diagnostic value of ENPP2 expression was evaluated using receiver operating characteristic curve analysis. We also validated our findings by performing real-time PCR on clinical liver cancer samples. Furthermore, we conducted gene set enrichment analysis using the Cancer Genome Atlas dataset to gain additional insights into the biological significance of ENPP2 in HCC. High ENPP2 expression in HCC patients is associated with gender and clinical stage, and is a significant prognostic factor for worse outcomes. ENPP2 expression is an independent risk factor for progression-free and disease-specific survival in both cohorts, suggesting its potential as an HCC biomarker. ENPP2's diagnostic value in HCC patients was confirmed by the area under the receiver operating characteristic curve, which was 0.806. real-time PCR analysis validated the higher expression of ENPP2 in clinical liver cancer tissues. Gene set enrichment analysis identified pathways enriched in HCC patients with high ENPP2 expression, including those related to the cell cycle, MTOR and T cell receptor signaling, and phosphatidylinositol signaling systems. We have demonstrated that ENPP2 is highly expressed in HCC and is a potential independent molecular marker for the diagnosis and prognosis of HCC.
