Mature-onset obesity and insulin resistance in mice deficient in the signaling adapter p62
Open accessAbstract
Signaling cascades that control adipogenesis are essential in the regulation of body weight and obesity. The adaptor p62 controls pathways that modulate cell differentiation. We report here that p62(-/-) mice develop mature-onset obesity, leptin resistance, as well as impaired glucose and insulin intolerance. The metabolic rate was significantly reduced in p62(-/-) nonobese mice, which displayed increased mRNA levels of PPAR-gamma and reduced levels of UCP-1 in adipose tissue. Basal activity of ERK was enhanced in fat from nonobese mutant mice. Embryo fibroblasts from p62(-/-) mice differentiated better than the wild-type controls into adipocytes, which was abrogated by pharmacological inhibition of the ERK pathway. p62 is induced during adipocyte differentiation and inhibits ERK activation by direct interaction. We propose that p62 normally antagonizes basal ERK activity and adipocyte differentiation and that its loss leads to the hyperactivation of ERK that favors adipogenesis and obesity.

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.
