Abstract

OBJECTIVE: Cannabinoid type 1 (CB1) receptor blockade decreases body weight and adiposity in obese subjects; however, the underlying mechanism is not yet fully understood. Nitric oxide (NO) produced by endothelial NO synthase (eNOS) induces mitochondrial biogenesis and function in adipocytes. This study was undertaken to test whether CB1 receptor blockade increases the espression of eNOS and mitochondrial biogenesis in white adipocytes. RESEARCH DESIGN AND METHODS: We examined the effects on eNOS and mitochondrial biogenesis of selective pharmacological blockade of CB1 receptors by SR141716 (rimonabant) in mouse primary white adipocytes. We also examined eNOS expression and mitochondrial biogenesis in white adipose tissue (WAT) and isolated mature white adipocytes of CB1 receptor-deficient (CB1(-/-)) and chronically SR141716-treated mice on either a standard or high-fat diet. RESULTS: SR141716 treatment increased eNOS expression in cultured white adipocytes. Moreover, SR141716 increased mitochondrial DNA amount, mRNA levels of genes involved in mitochondrial biogenesis, and mitochondrial mass and function through eNOS induction, as demonstrated by reversal of SR141716 effects by small interfering RNA-mediated decrease in eNOS. While high-fat diet-fed wild-type mice showed reduced eNOS expression and mitochondrial biogenesis in WAT and isolated mature white adipocytes, genetic CB1 receptor deletion or chronic treatment with SR141716 restored these parameters to the levels observed in wild-type mice on the standard diet, an effect linked to the prevention of adiposity and body weight increase. CONCLUSIONS: CB1 receptor blockade increases mitochondrial biogenesis in white adipocytes by inducing the expression of eNOS. This is linked to the prevention of high-fat diet-induced fat accumulation, without concomitant changes in food intake.

  • NOS3 is expressed at highest relative abundance in vascular endothelium, but is also found in neurons, epithelial cells, cardiomyocytes, adipocytes, and hepatocytes.

    “NOS3 (commonly called endothelial NOS or eNOS) is expressed to highest relative abundance in the vascular endothelium, but has also been found in neurons, epithelial cells, and cardiomyocytes [66] as well as adipocytes [67, 68] and hepatocytes [69-71].”

  • Nitric oxide production by the endothelial nitric oxide synthase has also been linked to enhanced adipose tissue mitochondrial biogenesis and prevention of high-fat diet-induced obesity.

    “Nitric oxide production by the endothelial nitric oxide synthase has also been linked to enhanced adipose tissue mitochondrial biogenesis and prevention of high-fat dietinduced obesity (200).”
  • Mitochondrial levels in white adipocytes are also increased in response to adrenergic stimulation, β-3 agonists, and CB1 blockade in mice, again in parallel with enhanced insulin sensitivity.

    “Mitochondrial levels in white adipocytes are also increased in response to adrenergic stimulation, ␤-3 agonists, and CB1 blockade in mice (195,199,200), again in parallel with enhanced insulin sensitivity.”

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.
