Diabetes Mellitus (DM) is defined as a metabolic disorder with a complex origin, characterized by chronic hyperglycemia. It is a highly prevalent disease and it is considered a worldwide epidemic. Because of its complex origin and its various complications, it is of great importance to understand its progression in the development of new strategies for prevention and treatment. One of the methods that have been of enormous importance to such understanding is proteomics, a very promising field for the discovery of early biomarkers of various diseases. Biomarkers are substances that indicate normal or pathological biological states, which can be quantified and monitored. They are so great tools for the diagnosis and prognosis of various diseases, and may even aid in prevention. This study involves the serpin family proteins (alpha-1-antitrypsin), the vitamin D binding protein, and kininogen. Based on previous studies, these proteins have been involved in some way in the development of diabetes. This study aims to validate these proteins, which have the potential for susceptibility biomarkers and/or progression of diabetes in non-obese diabetic mice (NOD). We hope they may become useful in the early diagnosis of diabetes and its complications. (AU)
