By crossing Twist1a-ERT2 with xmrk (a homolog of hyperactive form of the epidermal growth factor receptor) transgenic zebrafish, which develop hepatocellular carcinoma, approximately 80% of the double transgenic zebrafish show spontaneous cell dissemination of mCherry-labeled hepatocytes from the liver to the entire abdomen and tail regions in five days, through induction of epithelial to mesenchymal transition (EMT). Here, EGFR is linked to hepatocellular carcinoma.
