In addition, increased expression of TGFA (log2 fold change = −2.28), a potent mitogen for hepatocytes that is associated with hepatocarcinogenesis (Harada et al., 1999; Yeh et al., 2007), was observed in HCC cells resulting in upregulation of type I collagen (Figure 4). The gene discussed is TGFA; the disease is hepatocellular carcinoma.
