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 obtained from Diabetes mellitus type 1 and Diabetes type 2 patients was seen. Acetylation at these promoters increases gene expression and increases the inflammatory response as a result. Genome-wide location studies using chromatin immunoprecipitation (ChIP) coupled with DNA microarray analysis revealed significant changes in H3K4me2 and H3K9me2 patterns at key gene regions in high glucose-treated THP-1 monocytes, with relevant changes being observed in primary monocytes from diabetes patients. A possible treatment for vascular complications of diabetes exists with the SIRT1 gene, a member of Sirtuin family of genes. The SIRT1 enzyme has HDAC activity, and has been shown to modulate
