Acute stimulation of glucose metabolism in mice by leptin treatment

Abstract

Leptin is an adipocyte hormone that functions as an afferent signal in a negative feedback loop regulating body weight, and acts by interacting with a receptor in the hypothalamus and other tissues. Leptin treatment has potent effects on lipid metabolism, and leads to a large, specific reduction of adipose tissue mass after several days. Here we show that leptin also acts acutely to increase glucose metabolism, although studies of leptin's effect on glucose metabolism have typically been confounded by the weight-reducing actions of leptin treatment, which by itself could affect glucose homoeostasis. We have demonstrated acute in vivo effects of intravenous and intracerebroventricular administrations of leptin on glucose metabolism. A five-hour intravenous infusion of leptin into wild-type mice increased glucose turnover and glucose uptake, but decreased hepatic glycogen content. The plasma levels of insulin and glucose did not change. Similar effects were observed after both intravenous and intracerebroventricular infusion of leptin, suggesting that effects of leptin on glucose metabolism are mediated by the central nervous system (CNS). These data indicate that leptin induces a complex metabolic response with effects on glucose as well as lipid metabolism. This response is unique to leptin, which suggests that new efferent signals emanate from the CNS after leptin treatment.

Claims other papers make about this one

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

  • In wild-type mice, intravenous leptin increases glucose turnover and glucose uptake but decreases hepatic glycogen content.

    “In wild-type mice, i.v. leptin increased glucose turnover and glucose uptake but decreased hepatic glycogen content (91).”
  • The effect of leptin on glucose metabolism is similar whether leptin is administered intravenously or via intracerebroventricular infusion at much lower doses in both rats and mice.

    “the effect is similar whether leptin is administered i.v. or via i.c.v. infusion (at much lower doses) in both rats (106) and mice (91).”
  • At pharmacological doses, central administration of leptin in normal animals increases whole body glucose turnover and glucose uptake in skeletal muscle, heart, and brown adipose tissue, but not white adipose tissue, without changes in plasma insulin or glucose levels.

    “at pharmacological doses, central administration of leptin in normal animals increases whole body glucose turnover and glucose uptake in peripheral tissues including skeletal muscle, heart and brown adipose tissue (BAT), but not white adipose tissue (WAT), without changes in plasma insulin or glucose levels (91).”
  • Intracerebroventricular leptin can acutely stimulate glucose uptake in skeletal muscle.

    “In addition, intracerebroventricular leptin can acutely stimulate glucose uptake in skeletal muscle (Cusin et al., 1998; Haque et al., 1999; Kamohara et al., 1997; Minokoshi et al., 1999)”

  • Central leptin administration can acutely increase muscle glucose uptake and decrease hepatic glucose production through altered autonomic output.

    “Consistent with this, central leptin administration can acutely increase muscle glucose uptake (Kamohara et al., 1997) and decrease hepatic glucose production (van den Hoek et al., 2008) through altered autonomic output (Haque et al., 1999).”

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.
