The outcomes indicated that EMT was clearly weakened in HCC cells with HIF-1a knockdown co-culturing with hepatic stellate cells, the extent of which was similar to of TGM2 knockdown alone or combined, and EMT was also weakened in HCC-TGM2 OE cells with HIF-1a knockdown (Fig. 5e). Here, HIF1A is linked to hepatocellular carcinoma.
