Dietary fructose and dyslipidemia: new mechanisms involving apolipoprotein CIII.


PURPOSE OF REVIEW:Chronic consumption of fructose and fructose-containing sugars leads to dyslipidemia. Apolipoprotein (apo) CIII is strongly associated with elevated levels of triglycerides and cardiovascular disease risk. We reviewed the effects of fructose consumption on apoCIII levels and the role of apoCIII in fructose-induced dyslipidemia. RECENT FINDINGS:Consumption of fructose increases circulating apoCIII levels compared with glucose. The more marked effects of fructose compared with glucose on apoCIII concentrations may involve the failure of fructose consumption to stimulate insulin secretion. The increase in apoCIII levels after fructose consumption correlates with increased postprandial serum triglyceride. Further, RNA interference of apoCIII prevents fructose-induced dyslipidemia in nonhuman primates. Increases in postprandial apoCIII after fructose, but not glucose consumption, are positively associated with elevated triglycerides in large triglyceride-rich lipoproteins and increased small dense LDL levels. SUMMARY:ApoCIII might be causal in the lipid dysregulation observed after consumption of fructose and fructose-containing sugars. Decreased consumption of fructose and fructose-containing sugars could be an effective strategy for reducing circulating apoCIII and subsequently lowering triglyceride levels.

  • Living up to a name: the role of the VLDL receptor in lipid metabolism.

    abstract::The VLDL receptor (VLDLR) is a member of the LDL receptor family. The VLDLR was hypothesized to mediate fatty acid entry into peripheral tissues, on the basis of its expression in tissues that are active in fatty acid metabolism and its capacity to bind apolipoprotein-E-rich VLDL in vitro. This hypothesis initially pr...
