Diabetes mellitus type 1 factors include having a family member with the condition. The underlying mechanism involves an autoimmune destruction of the insulin-producing beta cells in the pancreas. Diabetes is diagnosed by testing the level of sugar or glycated hemoglobin (HbA1C) in the blood. Type 1 diabetes can be distinguished from type 2 by testing for the presence of autoantibodies. There is no known way to prevent type 1 diabetes. Treatment with insulin is required for survival. Insulin therapy is usually given by injection just under the skin but can also be delivered by an insulin pump. A diabetic diet and exercise are important
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
