Studies have shown that in contrast to a normal liver, there is an upregulation of FZD3/6/7 and Wnt3/4/5a expression in 95% of HCC and 68% of the surrounding tumor tissues, along with downregulation of sFRP1/5, which accumulates progressively with tumor advancement and the severity of fibrosis in surrounding tissues (72). The gene discussed is FZD3; the disease is neoplasm.
