[The interconnections of molecular mechanisms of hormone actions and their role in pathogenesis of obesity, insulin resistance, and diabetes mellitus].

Abstract

The various hormones, proteins and other compounds related to developing obesity, insulin resistance and type 2 diabetes are analyzed in the paper. 1) Leptin, ciliary neurutrophic factor, adiponectin, glucagon-like peptide 1, peptide YY, neuromedin S, as well as the protein receptors of these hormones decrease the food consumption, increase the energy turnover, and prevent obesity, insulin resistance, and type 2 diabetes development. The mediators of these hormone and receptor actions are melanocyte stimulating hormone (MSH), corticotropin-releasing hormone (CRH), and the others. 2) Ghrelin, endogenose cannabinoides, galanin-like peptide and the mediators of their actions: neuropeptide Y (NPY) and Agouti gene related protein (AGRP) increase the appetite and food consumption. Peroxisome proliferation-activated receptor (PPAR) performs the similar action on food intake. The activation of the first group compound functioning decreases the obesity, increases the energy turnover, facilitates the insulin action and prevents the insulin resistance and type 2 diabetes. Increasing the activities of the second group, as well as, decreasing the actions of the first one of substances induce the opposite effects and facilitate obesity, insulin resistance, and type 2 diabetes developments. The interconnections of the molecular mechanisms of so many hormone actions make the very complicated tusk to study the various endocrine disorders including diabetes mellitus as well.
