The peripheral effects of inhibiting the CB1 receptor has been appreciated through studies in diet-induced obese and liver-specific CB1 knockout mice. In this article, we systematically investigated gene expression changes in peripheral tissues of diet-induced obese mice treated with the CB1 inverse agonist AM251 [1-(2,4-dichlorophenyl)-5-(4-iodophenyl)-4-methyl-N-(1-piperidyl)pyrazole-3-carboxamide]. CB1 receptor inhibition led to down-regulation of genes within the de novo fatty acid and cholesterol synthetic pathways, including sterol regulatory element binding proteins 1 and 2 and their downstream targets in both liver and adipose tissue. In addition, genes involved in fatty acid β-oxidation were up-regulated with AM251 treatment, probably through the activation of peroxisome proliferator-activated receptor α (PPARα). In adipose tissue, CB1 receptor inhibition led to the down-regulation of genes in the tumor necrosis factor α signal transduction pathway and possibly to the activation of PPARγ, both of which would result in improved insulin sensitivity.}, issn = {0026-895X}, URL = {https://molpharm.aspetjournals.org/content/78/3/350}, eprint = {https://molpharm.aspetjournals.org/content/78/3/350.full.pdf}, journal = {Molecular Pharmacology} }
