Abstract

The adipocyte-derived secretory factor adiponectin promotes insulin sensitivity, decreases inflammation and promotes cell survival. No unifying mechanism has yet explained how adiponectin can exert such a variety of beneficial systemic effects. Here, we show that adiponectin potently stimulates a ceramidase activity associated with its two receptors, AdipoR1 and AdipoR2, and enhances ceramide catabolism and formation of its antiapoptotic metabolite--sphingosine-1-phosphate (S1P)--independently of AMP-dependent kinase (AMPK). Using models of inducible apoptosis in pancreatic beta cells and cardiomyocytes, we show that transgenic overproduction of adiponectin decreases caspase-8-mediated death, whereas genetic ablation of adiponectin enhances apoptosis in vivo through a sphingolipid-mediated pathway. Ceramidase activity is impaired in cells lacking both adiponectin receptor isoforms, leading to elevated ceramide levels and enhanced susceptibility to palmitate-induced cell death. Combined, our observations suggest a unifying mechanism of action for the beneficial systemic effects exerted by adiponectin, with sphingolipid metabolism as its core upstream signaling component.

  • Adiponectin has antidiabetic effects and antagonizes the progression of DCM by exhibiting potent anti-hypertrophic activity in cardiomyocytes and diminishing cardiac cell death by inhibiting inflammation.

    “Adiponectin has antidiabetic effects and antagonizes the progression of DCM by exhibiting potent anti-hypertrophic activity in cardiomyocytes and diminishing cardiac cell death by inhibiting inflammation [36-38].”

    From Role of Serum Biomarkers in Early Detection of Diabetic Cardiomyopathy in the West Virginian Population (2016) · cites this paper as [37]

    The Results section ('Anti-apoptotic effects of adiponectin on cardiac myocytes'; page unavailable) reports improved cardiomyocyte survival with adiponectin, and the Discussion links adiponectin to improved metabolic health. But the paper does not establish that it slows diabetic cardiomyopathy or prevents cardiac cell death by inhibiting inflammation. Contrary to the claimed anti-hypertrophic activity, the Results report cardiac hypertrophy in 20- and 30-week-old adiponectin-transgenic mice. (LLM, conf=0.90)

  • In peripheral tissues, adiponectin promotes liver insulin sensitivity via several independent mechanisms: an AMPK-dependent mechanism involving increased ACC phosphorylation, an AMPK-independent mechanism involving reduction in liver ceramide levels, and an IL-6-dependent mechanism involving upregulation of IRS-2 through STAT3 activation.

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.
