SNAI1 and hepatocellular carcinoma: A previous study reported that aberrant KDM6B expression up‐regulates Slug to induce EMT, invasive migration, stem cell‐like traits and metastatic properties in hepatocellular carcinoma [8], although KDM6B plays a permissive role in TGF‐β‐induced EMT in mammary epithelial cells by stimulating Snail expression [20].
