Abstract

Fatty liver disease is associated with obesity and type 2 diabetes, and hepatic lipid accumulation may contribute to insulin resistance. Histone deacetylase 3 (Hdac3) controls the circadian rhythm of hepatic lipogenesis. Here we show that, despite severe hepatosteatosis, mice with liver-specific depletion of Hdac3 have higher insulin sensitivity without any changes in insulin signaling or body weight compared to wild-type mice. Hdac3 depletion reroutes metabolic precursors towards lipid synthesis and storage within lipid droplets and away from hepatic glucose production. Perilipin 2, which coats lipid droplets, is markedly induced upon Hdac3 depletion and contributes to the development of both steatosis and improved tolerance to glucose. These findings suggest that the sequestration of hepatic lipids in perilipin 2–coated droplets ameliorates insulin resistance and establish Hdac3 as a pivotal epigenomic modifier that integrates signals from the circadian clock in the regulation of hepatic intermediary metabolism.

  • Mice with a liver-specific deletion of Hdac3 display increased expression of de novo lipogenesis enzymes due to a constitutively active transcriptional environment, resulting in fatty liver disease and elevated serum cholesterol.

    “Mice with a liver-specific deletion of Hdac3 display an increased expression of de novo lipogenesis enzymes due to a constitutively active transcriptional environment, resulting in fatty liver disease and elevated serum cholesterol [178,179].”

    From Rett syndrome: a neurological disorder with metabolic components (2018) · cites this paper as [179]

    The Results sections on Hdac3-depleted fatty liver and metabolic rerouting report that liver-specific Hdac3 deletion increases expression of lipid-synthesis genes and causes hepatosteatosis. The paper describes derepression of lipogenic genes, but does not establish the claimed constitutively active transcriptional environment; no passage found reports elevated serum cholesterol (searched: cholesterol, plasma cholesterol). Page numbers were not available in our copy. (LLM, conf=0.86)

  • Loss of HDAC3 in liver cells leads to metabolic syndrome and FLD.

    “its loss in liver cells leads to metabolic syndrome and FLD56,57.”

    From A suppressor screen in Mecp2 mutant mice implicates cholesterol metabolism in Rett syndrome (2013) · cites this paper as [56]

    The Results sections on hepatic Hdac3 deletion report severe hepatosteatosis in mice, supporting the fatty liver disease (FLD) portion. They do not report that the mice developed metabolic syndrome; instead, the section on glucose output and insulin sensitivity reports lower fasting glucose and insulin and improved insulin sensitivity despite the fatty liver. (LLM, conf=0.90)

  • FLD in 129.Mecp2tm1.1Bird mice is similar to that in a liver-specific knockout of HDAC3.

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.
