SNAI2 and hepatocellular carcinoma: Herein, our data show that SNAI2 behaves as a tumor suppressor by increasing drug sensitivity via inhibiting ABC transporter genes in HCC cells based on the following evidences: First, inhibition of SNAI2 expression induces proliferation of non-cancer hepatic cells, promotes anchorage-independent growth of HCC cells and up-regulates CSC genes as well.
