The Niemann–Pick C1-like intracellular cholesterol transporter gene and a number of genes in the cholesterol synthesis pathway are transcriptionally regulated by SREBP-2. The liganded Ah receptor increases proteolytic turnover of transcriptionally active SREBP2. Thus, Ah receptor ligands are capable of attenuating cholesterol uptake into Caco-2 cells.
