Our result showed that expression of SNAI1, N-cadherin and Vimentin was reduced in CoCl2-treated HCC cells after infection with Ad-shHIF1α, whereas E-cadherin was increased in CoCl2-treated HCC cells after infection with Ad-shHIF1α (Figure 4A and B). This evidence concerns the gene SNAI1 and hepatocellular carcinoma.
