Abstract

High plasma levels of the apo-B-containing lipoproteins are casually implicated in the pathogenesis of atherosclerosis. This finding, backed by decades of animal and human studies, has sparked interest in defining which classes of apo-B-containing lipoprotein particles are most atherogenic. Although small LDL particles and larger remnant lipoproteins both appear to be atherogenic, it has been difficult to discern which particles are the most atherogenic. Here, we summarize several mouse models that have provided insights into this issue. The influence of lipoprotein size on susceptibility to atherosclerosis was examined by studying the phenotypes of two strains of mice with virtually identical levels of plasma cholesterol--Ldlr(-/-)Apob(100/100) and Apoe(-/-) Apob(100/100) mice. The Ldlr(-/-) Apob(100/100) mice, where the cholesterol is in small LDL particles, had far more atherosclerosis than Apoe(-/-) Apob(100/100) mice, where virtually all of the cholesterol was in larger, VLDL-sized particles. Another intriguing animal model is the Gpihbp1-deficient mouse. GPIHBP1 is an endothelial cell platform for lipolysis, and mice lacking this protein have an accumulation of large, triglyceride-rich lipoproteins. Defining the extent of atherosclerosis in these mice should provide new insights into the atherogenicity of large, triglyceride-rich lipoproteins.

  • A variety of animal models produced using dietary or genetic manipulations have confirmed that chylomicron remnants are atherogenic.

    “A variety of animal models produced using dietary or genetic manipulations have confirmed that chylomicron remnants are atherogenic (139, 144).”

    From Evaluation and Treatment of Hypertriglyceridemia: An Endocrine Society Clinical Practice Guideline (2012) · cites this paper as [144]

    In “Apo-B–Containing Lipoproteins and Atherosclerosis” (page unavailable), the paper says there is substantial evidence that chylomicron and VLDL remnants can be atherogenic. Its mouse-model discussion reports lesions in genetically modified mice with elevated remnants, but cautions that those mice also have LDL-sized particles, making the remnants’ contribution difficult to isolate. The cited passages do not establish the claim that a variety of dietary and genetic animal models have confirmed chylomicron remnants’ atherogenicity. (LLM, conf=0.83)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
