Abstract

Adiponectin (ApN) is an adipocytokine that plays a fundamental role in energy homeostasis and counteracting inflammation. We examined whether ApN could be induced in a nonadipose tissue, the skeletal muscle, in vivo, and in cultured myotubes in response to lipopolysaccharides or proinflammatory cytokines. We next explored the underlying mechanisms. In vivo, injection of lipopolysaccharides to mice caused, after 24 h, an approximately 10-fold rise in ApN mRNA abundance and a concomitant 70% increase in ApN levels in tibialis anterior muscle. This ApN induction was reproduced in C2C12 myotubes cultured for 48 h with a proinflammatory cytokine combination, interferon-gamma + TNFalpha. This effect occurred in a time- and dose-dependent manner. Several pieces of evidence suggest that nitric oxide (NO) mediates this up-regulation by cytokines in myotubes or muscle. First, ApN was induced in vitro exclusively in the experimental conditions that stimulated NO production. Second, inducible NO synthase mRNA induction or NO production clearly preceded ApN mRNA induction. Third, preventing NO production by inhibitors of the NO synthases, nitro-L-arginine methyl ester or NG-methyl-L-arginine, suppressed the inductive effect of the cytokines in vitro and in vivo. Finally, ApN mRNA induction by cytokines was reproduced in cultured human myotubes. In conclusion, our data provide evidence that adiponectin is up-regulated in vivo and in vitro in human and rodent myotubes in response to inflammatory stimuli. The underlying mechanisms seem to involve a NO-dependent pathway. This overexpression may be viewed as a local antiinflammatory protection and a way to deliver extra energy supplies during inflammation.

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.
