Abstract
Diabetes Mellitus (DM) and its chronic complications are the greatest public health problem. It is a must to develop approaches that help to control glycemia and to reduce the incidence of complications. Target territories to develop complications, which will be focused on in this proposal, include kidney, cardiovascular system, brain (Alzheimer's Disease also referred to as DM3) and liver. This project aims to unravel molecular mechanism concerning glycemic control and the development of complications in DM1 and/or in DM2. For that, we will investigate mechanisms contributing to the development or improvement of: 1) glycemic control: GLUT4 regulation in animal models and inspiratory exercise in humans; 2) Diabetic Renal Disease: genetic susceptibility markers and renal tubular disease related to urinary molecular markers (cells from urinary sediment); 3) Cardiovascular Disease: focusing on Atherosclerosis and endothelial progenitor cells migration in humans, and Cardiomyopathy in animal model; 4) Alzheimer's Disease: focusing on glucose disposal for specific brain areas, based on the expression of glucose transporters (post mortem human brain); and 5) Hepatic Diseases: non-alcoholic fatty liver disease in animal model, and Mauriac Syndrome in DM1 subjects. Several methodologies will be adopted: in vivo, in vitro and in silico analyses; Molecular Biology techniques for evaluation of gene expression (transcriptional, translational and epigenetic regulations). We expect to yield a myriad of results capable of remarkably enriching knowledge of the area, and significantly contributing to the health of Diabetes Mellitus patients. (AU)
