Abstract

miR-33 in Cholesterol Control: With the well-established link between serum cholesterol levels and cardiovascular disease and the availability of effective cholesterol-lowering drugs, cholesterol screening has rapidly become a routine part of health care. Yet, much remains to be learned about how cholesterol levels are regulated at the cellular level (see the Perspective by Brown et al. ). Now, Najafi-Shoushtari et al. (p. 1566 , published online 13 May) and Rayner et al. (p. 1570 , published online 13 May) have discovered a new molecular player in cholesterol control—a small noncoding RNA that, intriguingly, is embedded within the genes coding for sterol regulatory element-binding proteins (SREBPs), transcription factors already known to regulate cholesterol levels. This microRNA, called miR-33, represses expression of the adenosine triphosphate–binding cassette transporter A1, a protein that regulates synthesis of high-density lipoprotein (HDL, or “good” cholesterol) and that helps to remove “bad” cholesterol from the blood. Reducing the levels of miR-33 in mice boosted serum HDL levels, suggesting that manipulation of this regulatory circuit might be therapeutically useful.

  • Most of the beneficial effects of miR-33 on atherosclerosis have been attributed to its ability to increase circulating levels of HDL-C and/or promote macrophage cholesterol efflux.

    “Most of the beneficial effects of miR-33 on atherosclerosis have been attributed to its ability to increase circulating levels of HDL-C and/or promote Mθ cholesterol efflux (Rayner et al., 2011b; Rayner et al., 2010)”

    From Genetic dissection of the impact of miR-33a and miR-33b during the progression of atherosclerosis (2017) · cites this paper as Rayner et al., 2010

    The paper reports the opposite direction of effect: miR-33 reduces macrophage cholesterol efflux and circulating HDL, while antagonizing miR-33 increases both. It describes these pathways as relevant to atherosclerosis but does not establish beneficial effects of miR-33 on atherosclerosis. (LLM, conf=0.90)

    Checked by a reasoning model — may be wrong.

    Experimental — accuracy not yet measured
  • miR-33 negatively regulates ABCA1 in both the periphery and the brain.

    “Previously, it was shown that miR‐33 negatively regulates ABCA1 in both the periphery and the brain. 15 , 16 , 17 , 18”

    From Deletion of miR-33, a regulator of the ABCA1–APOE pathway, ameliorates neuropathological phenotypes in APP/PS1 mice (2024) · cites this paper as [16]

    The paper reports that miR-33 represses ABCA1 in macrophages and hepatocytes, supporting regulation in the periphery. It also reports abundant miR-33 expression in mouse brain, but does not show that miR-33 negatively regulates ABCA1 there (searched: brain and brain-related cell types). The indexed copy provides no page numbers for these passages. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • In vivo antagonism or genetic deletion of miR-33 enhances hepatic ABCA1 expression and increases circulating HDL-cholesterol.

    “in vivo antagonism or genetic deletion of miR-33 enhances hepatic ABCA1 expression and increases circulating HDL-cholesterol (HDL-C) (Marquart et al., 2010; Najafi-Shoushtari et al., 2010; Rayner et al., 2010).”

    From Genetic dissection of the impact of miR-33a and miR-33b during the progression of atherosclerosis (2017) · cites this paper as Rayner et al., 2010

    The in vivo mouse passage (indexed under Abstract; Fig. 4D–F, page unavailable) reports that anti-miR-33 increased hepatic ABCA1 protein by 50% and plasma HDL by 25% after six days. It describes lentiviral antagonism, not genetic deletion of miR-33, so the deletion part is not supported by this source. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • miR-33a and miR-33b are intronic miRNAs encoded within the SREBP-2 and SREBP-1 genes respectively.

    “miR-33a and miR-33b are intronic miRNAs encoded within the SREBP-2 and SREBP-1 genes respectively (Marquart et al., 2010; Najafi-Shoushtari et al., 2010; Rayner et al., 2010).”

    From Genetic dissection of the impact of miR-33a and miR-33b during the progression of atherosclerosis (2017) · cites this paper as Rayner et al., 2010

    The passage labeled Abstract (page not provided) states that hsa-miR-33a is encoded within intron 16 of SREBF2, supporting the miR-33a/SREBP-2 part of the claim. The passages from our copy do not establish that miR-33b is encoded within SREBP-1. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • The most well-known target gene of miR-33a/b is ABCA1.

    “The most well-known target gene of miR-33a/b is ATP-binding cassette subfamily A member 1 (ABCA1).”

    From Critical Role of microRNA-33a/b in Cardiovascular and Metabolic Disease: Molecular Mechanisms and Therapeutic Perspectives (2026) · cites this paper as [12]

    The paper’s Abstract identifies ABCA1 as a target of miR-33 in human and mouse cells, and its reporter experiments support direct targeting. Its description of the studied miRNA specifies human miR-33a and its mouse homolog; the copy does not establish the claim for miR-33b or rank ABCA1 as the most well-known target. (LLM, conf=0.84)

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.
