Research Abstract

We used the luciferase plasmid containing the cholesterol transporter, intestinal ABCA1 gene promoter to clarify the molecular mechanism of the inhibition of intestinal cholesterol absorption by lactostatin in Caco-2 cells. Our results suggested that PPAR/LXR responsive element related to the suppression of cholesterol absorption by lactostatin in Caco-2 cells. An oleosin having a hypocholesterolemic action was investigated to clarify the active sequence of its induced a hypocholesterolemic action by an exhaustive analysis using a peptide array. We found two novel bile acid binding peptides. Two novel bile acid binding peptides exhibited the greater inhibition of micellar solubility of cholesterol in vitro compared with a bile acid binding peptide VAWWMY as a positive control. We found that QEK derived from soybean beta-conglycinin alpha prime subunit exhibited the significant increase in CYP7A1 mRNA levels compared to the control group in HepG2 cells.
