Characterization of free fatty acid receptors expression in an obesity rat model with high sucrose diet

AbstractIntroduction/aims: In recent years, it has been shown that free fatty acids receptors (FFAR) of whose function in the cell surface plays a significant role in the regulation of cell function and nutrition as well are activated by various endogenous ligands, but mainly by fatty acids. Within FFAR of our interest are GPR 41, 43 and 120. The functions of these receptors are varied and dependent on the tissue where they are. The activation and signaling of these receptors, FFAR, are involved in many physiological processes, and currently the target of many drugs in metabolic disorders like obesity, diabetes and atherosclerosis.Material and methods: Obesity was induced with hypercaloric diet (HD) in male Wistar rats for 20 weeks (n = 10). At the end, adipose tissue (abdominal and subcutaneous) was taken to perform assays for relative quantification mRNA expression by end-point RT-PCR and protein level expression by Western blot.Results: These present data have shown for the first time that total mRNA i...
