Role of adipose tissue cannabinoid 1 receptor (CB1R) on lipolysis and consequences on lipid and carbohydrate metabolism in mice
2017
Role of adipose tissue cannabinoid receptor 1 (CB1R) on lipolysis and consequences on lipid and carbohydrate metabolism in miceObesity is accompanied with lipolysis deregulation responsible for excessive Free Fatty Acid (FFA) release, which are key actors in the implementation of peripheral insulin resistance. In parallel, it is now well established that obesity is associated with EndoCannabinoid System (ECS) activity dysfunction in several metabolic tissues. If it is well described that overactivation of this system in the Adipose Tissue (AT) is favourable to its expansion, the consequences on lipolysis remain to be elucidated.The main objective of this thesis work was to precise the role …

We assessed, in this study, the effects of PPARα deficiency on the expression of mRNAencoding for insulin gene transcription factors in pancreatic β-cells along with thoseimplicated in inflammation in adipose tissues. On fasting, the adult PPARα-null mice werehypoglycemic. Serum insulin concentrations and its pancreatic mRNA transcripts weredownregulated in PPARα-null mice, suggesting that PPARα gene deletion contributes to lowinsulin gene transcription. The PPARα gene deletion downregulates the mRNA expression ofinsulin gene transcription factors, i.e., Pdx-1, Nkx6.1 and MafA. Besides, the pancreaticfunction was diminished by PPARα deficiency as PPARα-null mice expressed low pancreaticGlut…
