Finally, we tested if the methyl binding protein MECP2, which is known to control gene expression through the interaction with transcriptional repressors [7], as well as three DNA methyl transferases; DNMT1, DNMT3A and DNMT3B, show differential expression in pancreatic islets from patients with type 2 diabetes. The gene discussed is MECP2; the disease is type 2 diabetes mellitus.
