The epithelial and endothelial tyrosine kinase/bone marrow tyrosine kinase gene in chromosome X protein (BMX), a member of the Tec (tyrosine kinase expressed in hepatocellular carcinoma) family of non-receptor tyrosine kinases, is present in epithelial, endothelial, and granulomonocytic cells [33]. This evidence concerns the gene NTRK1 and hepatocellular carcinoma.
