Our objective in this study was to elucidate whether SHP is the mediator of the reduction of TG‐rich ApoB‐containing lipoproteins triggered by GSPE. We show that GSPE inhibited TG and ApoB secretion in human hepatocarcinoma HepG2 cells and had and hypotriglyceridemic effect in wild‐type mouse. The TG‐lowering action of GSPE was abolished in HepG2 cells transfected with a SHP‐specific siRNA and in a SHP‐null mouse. Moreover, in mouse liver, GSPE downregulated several lipogenic genes, including steroid response element binding protein 1c (SREBP‐1c), and upregulated carnitine palmitoyltransferase‐1A (CPT‐1A) and apolipoprotein A5 (ApoA5), in a SHP‐dependent manner. In HepG2 cells GSPE also inhibited ApoB secretion, but in a SHP‐independent manner. In conclusion, SHP is a key mediator of the hypotriglyceridemic response triggered by GSPE. This novel signaling pathway of procyanidins through SHP may be relevant to explain the health effects ascribed to the regular consumption of dietary flavonoids.</jats:p> Dietary procyanidins lower triglyceride levels signaling through the nuclear receptor small heterodimer partner Molecular Nutrition & Food Research |
