We investigated the regulation of the expression of genes encoding the drug-metabolizing enzymes CYP1A1 and CYP1A2 in 3D spheroids comprised of cells of the human hepatocellular carcinoma cell JHH1, Huh7, and HepG2. Expression of CYP1A1 and CYP1A2 in the spheroids was higher than that in 2D cultured cells. Expression of CYP1A1 and CYP1A2 is regulated by aryl hydrocarbon receptor (AhR) in 2D cultured cells. Knockdown of AhR in spheroids suppressed CYP1A1 expression; however, CYP1A2 expression levels remained unchanged. Moreover, we found that pregnane X receptor (PXR) likely regulated CYP1A2 expression in JHH1, HepG2, and Huh7 spheroids and that CYP1A1 expression in JHH1 and Huh7 3D spheroids is regulated not only by AhR but also by PXR. It is well known that gene expression levels are different between 3D spheroids and 2D monolayer cultured cells, and our results indicate that the regulation of gene expression also varies between the two culture conditions. Taken together, these results underlie a novel finding regarding the regulation of drug-metabolizing enzyme expression in liver cancer cells growing as 3D spheroids."xsd:string |
