Core Tip
Core Tip: This study investigates the expression of the PEA3 subfamily genes (ETV1, ETV4, ETV5) in cholangiocarcinoma (CCA) and their clinical relevance. Using data from cancer genome atlas and genotype-tissue expression project databases, we identified significantly elevated levels of ETV1, ETV4 and ETV5 in CCA. High expression of ETV1 and ETV4 was explicitly correlated with shorter overall survival in CCA patients. Functional assays demonstrated that silencing PEA3 genes reduces invasion and metastasis in CCA cells in vitro and in vivo. These findings suggest that ETV4 may be a valuable prognostic biomarker for survival of CCA patients.
