In hepatocellular carcinoma (HCC), the upregulated fatty acid-binding protein 1 (FABP1) interacts with the VEGF receptor and Src via the focal adhesion kinase (FAK) and enhances the expression of the angiogenic vascular endothelial growth factor A (VEGF-A) [6]. This evidence concerns the gene PTK2 and hepatocellular carcinoma.
