Abstract

MicroRNAs (miRs) are small non-protein-coding RNAs that bind to specific mRNAs and inhibit translation or promote mRNA degradation. Recent reports have indicated that miR-33, which is located within the intron of sterol regulatory element-binding protein (SREBP) 2, controls cholesterol homoeostasis and may be a potential therapeutic target for the treatment of atherosclerosis. Here we show that deletion of miR-33 results in marked worsening of high-fat diet-induced obesity and liver steatosis. Using miR-33−/−Srebf1+/− mice, we demonstrate that SREBP-1 is a target of miR-33 and that the mechanisms leading to obesity and liver steatosis in miR-33−/− mice involve enhanced expression of SREBP-1. These results elucidate a novel interaction between SREBP-1 and SREBP-2 mediated by miR-33 in vivo.

  • The obesity and insulin resistance in miR-33a knockout mice on a high-fat diet is attributed to a central nervous system phenotype, specifically an increase in food intake.

    “This has been attributed to a central nervous system phenotype, specifically an increase in food intake.”

    From Critical Role of microRNA-33a/b in Cardiovascular and Metabolic Disease: Molecular Mechanisms and Therapeutic Perspectives (2026) · cites this paper as [39]

    The Results section reports increased food intake in high-fat-diet-fed miR-33 knockout mice, but its pair-feeding experiment explicitly concludes that their greater weight gain is not caused by a change in food intake. The Discussion instead attributes obesity to enhanced SREBP-1 expression. The supplied passages have no page numbers. (LLM, conf=0.90)

    Checked by a reasoning model — may be wrong.

  • A later report by the same group showed a dramatic increase in body weight and insulin resistance in miR-33−/− mice when fed a high fat (60% saturated fat) diet.

    “a later report by the same group did show a dramatic increase in BW and insulin resistance in miR-33−/− mice when fed a high fat (60% saturated fat) diet (Horie et al., 2013).”

    From Genetic dissection of the impact of miR-33a and miR-33b during the progression of atherosclerosis (2017) · cites this paper as Horie et al., 2013

    The Results sections on obesity and insulin tolerance report markedly increased body weight and impaired insulin tolerance in miR-33−/− mice fed a high-fat diet. Our copy does not specify that the diet contained 60% saturated fat, so that detail is unsupported. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • MiR-33 can modulate SREBP1 expression and miR-33 knockout mice are prone to obesity and liver steatosis.

    “MiR-33 can modulate SREBP1 expression and miR-33 knockout mice are prone to obesity and liver steatosis [35].”
  • Loss of miR-33 results in a predisposition to the development of obesity and insulin resistance.

    “Additionally, a later report by this same group has demonstrated that loss of miR-33 results in a predisposition to the development of obesity and insulin resistance (Horie et al., 2013)”
  • miR-33 knockout mice have adverse metabolic effects.

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.
