Diabetes mellitus type 2 estimated that 20% of people with diabetes in the United States do not realize that they have the disease. Diabetes mellitus type 2 is characterized by high blood glucose in the context of insulin resistance and relative insulin deficiency. This is in contrast to diabetes mellitus type 1 in which there is an absolute insulin deficiency due to destruction of islet cells in the pancreas and gestational diabetes mellitus that is a new onset of high blood sugars associated with pregnancy. Type 1 and type 2 diabetes can typically be distinguished based on the presenting circumstances. If the diagnosis is
Epigenetics of diabetes Type 2 A possible link between DNA methylation and insulin resistance was shown through monozygotic twin comparisons and bisulfite pyrosequencing to measure the global DNA methylation of Alu repeats in peripheral blood leukocytes. Alu elements are known to create genomic instability and affect gene expression, and have been implicated in numerous human diseases. Epigenetic alterations arising during the lifetime of monozygotic twins in Alu repeats resulted in an increase in genomic s instability, and consequently cause insulin resistance and type 2 diabetes. show that methylation levels at all four CpG sites displayed an increase in Alu methylation. This study provides the first
