LDLR and hepatocellular carcinoma: Human hepatoma Huh–7 cells were transfected with pLDLR-Luc and the expression plasmid for blasticidin S deaminase and were then cultured in the presence of blasticidin S. Blasticidin S-resistant clones (Huh–7/LDLR-Luc cells) were isolated and expanded and were treated with approximately 100 food components at 100 μM for 12 h.
