SLC22A5 and hepatocellular carcinoma: HEK293 cells stably transfected with the coding sequence of the human OCTN2 (Fig. 1A) and Human hepatocellular carcinoma cells (Huh-7) cells transiently transfected with the human OCTN2 (Fig. 1B) exposed for 20 min to mβcd were characterized by an ∼50% depletion of total cholesterol in comparison with the untreated cells.
