Diabetes mellitus type 1 According to the current definition, two fasting glucose measurements above 126 mg/dl (7.0 mmol/l) is considered diagnostic for diabetes mellitus. In type 1, pancreatic beta cells in the islets of Langerhans are destroyed, decreasing endogenous insulin production. This distinguishes type 1's origin from type 2. Type 2 diabetes is characterized by insulin resistance, while type 1 diabetes is characterized by insulin deficiency, generally without insulin resistance. Another hallmark of type 1 diabetes is islet autoreactivity, which is generally measured by the presence of autoantibodies directed towards the beta cells. The appearance of diabetes-related autoantibodies has been shown to be able
Epigenetics of diabetes Type 2 shown. MiR-143 has also been experimentally shown to regulate genes that are crucial for adipocyte differentiation, (including GLUT4, Hormone-sensitive lipase, the fatty acid-binding protein, aP2 and PPAR-γ2), demonstrating that miRNAs are also involved in fat metabolism and endocrine function in humans. Epigenetics may play a role in a wide array of vascular complications and in diabetes. The epigenetic variations involved with diabetes can change chromatin structure as well as gene expression. Regardless of whether glycemic control has been achieved through treatment these epigenetic mechanisms are lasting and do not change with the alteration of diet. The most common vascular complication
