Abstract

EVI2A has emerged as a significant biomarker in various diseases; however, its biological role and mechanism in kidney renal clear cell carcinoma (KIRC) remains unexplored. We used TCGA and GEO databases to analyze EVI2A gene expression comprehensively and performed pan-cancer assessments. Clinical relevance was evaluated through Kaplan-Meier analysis and ROC curves. The gene’s immune relevance was explored through analyses of the tumor microenvironment (TME), Tumor Immune Single-cell Hub (TISCH), immune checkpoints, and immunotherapy sensitivity. Our results indicate that EVI2A expression is upregulated in KIRC, showing correlations with tumor grade and T/N/M stage. EVI2A demonstrates high diagnostic accuracy (AUC=0.906) and predicts poor overall and progression-free survival in KIRC patients. Furthermore, EVI2A expression exhibits significant associations with immunity, including TME scores and specific immune cell types such as Tfh cells, CD4 memory T cells, and CD8+ T cells. Elevated EVI2A expression suggests increased sensitivity to PD-1/CTLA-4 and tyrosine kinase inhibitors. In vitro assays confirmed the impact of EVI2A on KIRC behavior, with its knockdown resulting in reduced cell proliferation and migration. In conclusion, our comprehensive analysis identifies EVI2A as a promising biomarker and a novel therapeutic target for intervening in KIRC. These findings hold significant implications for further research and potential clinical applications.
