Effects of anthocyanin on cholesterol efflux from mouse peritoneal macrophage foam cells / 中国病理生理杂志

ABSTRACT

AIM: To explore the effect of anthocyanin on cholesterol efflux and elucidate its possible molecular mechanism. METHODS: Mouse Peritoneal macrophages were loaded with 50 mg/L AcLDL to induce macrophage-derived foam cells. Cholesterol efflux from macrophage-derived foam cells induced by anthocyanin was determined by enzymatic methods. PPAR-? mRNA and protein expression in macrophage-derived foam cells was assayed by quantitative PCR and western blotting. RESULTS: Anthocyanins had the capacity of promoting cholesterol efflux from mouse peritoneal macrophage-derived foam cells and increased PPAR-? mRNA and protein expression. CONCLUSION: Anthocyain-induced cholesterol efflux may be related to its enhancing PPAR-? mRNA and protein expression.
