CAV1 and hepatocellular carcinoma: The expression level of Cav-1 is positively correlated with the invasiveness of hepatocellular carcinoma (HCC), and knocking out Cav-1 can inhibit the epithelial mesenchymal transition (EMT) process through Wnt/β-catenin pathway, thereby inhibiting the malignant behavior of HCC metastasis (19).
