Abstract

Angiopoietin-like 3 (ANGPTL3) is a secreted protein with both angiogenesis and lipid metabolism functions. We generated knockout mice that failed to express the Angptl3 gene, and analyzed the lipid metabolism. Angptl3-null mice, fed a normal diet or a high-fat, high-calorie (HFC) diet, revealed markedly low plasma lipid concentrations, especially plasma triglyceride concentration, although the body weight and liver weight were not different between Angptl3-null mice and wild-type mice. Angptl3-null mice fed an HFC diet also revealed a significantly reduced epididymal adipose tissue weight despite there being no difference in adipocyte size between them and wild-type mice. A triglyceride clearance study indicated that the lower plasma triglyceride concentration in Angptl3-null mice was caused by an accelerated clearance of triglyceride. In fact, lipoprotein lipase and hepatic lipase activities in the post-heparin plasma of Angptl3-null mice were 1.57 times and 1.42 times higher than those of wild-type mice, respectively. These results suggest that ANGPTL3 may have an effect not only on lipid metabolism but also on adipose formation.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • ANGPTL3 inhibits lipoprotein lipase, which results in increased blood lipid levels.

    “ANGPTL3 inhibits the lipoprotein lipase, which results in increased blood lipid levels [143–145].”
  • Evinacumab is a monoclonal antibody inhibiting angiopoietin-like 3 (ANGPTL3).

    “Evinacumab is a monoclonal antibody inhibiting angiopoietin-like 3 (ANGPTL3).”

    From Established and Emerging Lipid-Lowering Drugs for Primary and Secondary Cardiovascular Prevention (2023) · cites this paper as [144]

    The Introduction identifies ANGPTL3, and the Discussion examines its role in lipid metabolism in knockout mice. Neither section addresses evinacumab or an antibody that inhibits ANGPTL3; searches for the drug name and anti-ANGPTL3 monoclonal antibodies found no supporting passage. (LLM, conf=0.76)

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.
