EPB41L1-5 is known to maintain cell morphology and signal transduction, with evidence suggesting it can inhibit tumor progression. However, its role in kidney renal clear cell carcinoma (KIRC) is not fully understood. This study evaluated EPB41L1-5's prognostic value in KIRC using bioinformatics methods and validation through qPCR, immunohistochemistry, and cell functional experiments. The results demonstrated a decreased expression of EPB41L in KIRC tissue compared to normal renal tissue, correlating with lower survival rates. Low EPB41L expression was also associated with overall survival in KIRC. Additionally, EPB41L was found to be involved in extracellular matrix regulation, G protein-coupled receptor ligand binding, and multiple immune cell infiltrations. In addition, their elevated methylation levels are associated with poor prognosis in KIRC patients. Overall, EPB41L family is a potential molecular marker for predicting KIRC prognosis, offering insights for therapeutic development.
