GATA1 and diabetes mellitus: The expression of GATA1 was shown to be markedly decreased (84% and 78%) in diabetic arteries relative to the expression in arteries from non-diabetic subjects as assessed using immunoblotting (Fig 5A) or real-time PCR (Fig 5B), respectively, which indicates that GATA1 might be involved in the development of atherosclerosis in individuals with diabetes.
