Abstract

Background—: Recent studies suggest that the oxygen-sensing pathway consisting of transcription factor hypoxia-inducible factor and prolyl hydroxylase domain proteins (PHDs) plays a critical role in glucose metabolism. However, the role of adipocyte PHD in the development of obesity has not been clarified. We examined whether deletion of PHD2 , the main oxygen sensor, in adipocytes affects diet-induced obesity and associated metabolic abnormalities. Methods and Results—: To delete PHD2 in adipocyte, PHD2 -floxed mice were crossed with aP2-Cre transgenic mice ( Phd2 f/f /aP2-Cre) . Phd2 f/f /aP2-Cre mice were resistant to high-fat diet–induced obesity (36.7±1.7 versus 44.3±2.0 g in control; P <0.01) and showed better glucose tolerance and homeostasis model assessment–insulin resistance index than control mice (3.6±1.0 versus 11.1±2.1; P <0.01). The weight of white adipose tissue was lighter (epididymal fat, 758±35 versus 1208±507 mg in control; P <0.01) with a reduction in adipocyte size. Macrophage infiltration into white adipose tissue was also alleviated in Phd2 f/f /aP2-Cre mice. Target genes of hypoxia-inducible factor, including glycolytic enzymes and adiponectin, were upregulated in adipocytes of Phd2 f/f /aP2-Cre mice. Lipid content was decreased and uncoupling protein-1 expression was increased in brown adipose tissue of Phd2 f/f /aP2-Cre mice. Knockdown of PHD2 in 3T3L1 adipocytes induced a decrease in the glucose level and an increase in the lactate level in the supernatant with upregulation of glycolytic enzymes and reduced lipid accumulation. Conclusions—: PHD2 in adipose tissue plays a critical role in the development of diet-induced obesity and glucose intolerance. PHD2 might be a novel target molecule for the treatment of obesity and associated metabolic abnormalities.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Adipocyte-specific deletion of PHD2 produces mice resistant to HFD-induced obesity and, despite elevated HIF-1α and HIF-2α, improved glucose tolerance and insulin sensitivity.

    “In contrast, adipocyte-specific deletion of PHD2 produces mice that are resistant to HFD-induced obesity and, despite elevated levels of both HIF-1α and HIF-2α, the mice display improved glucose tolerance and insulin sensitivity (7).”

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.
