Introduction
Micro- and macrovascular complications are the most important cause of increased morbidity and mortality in type 1 and type 2 diabetic patients. Early renal changes in diabetes are characterized by kidney enlargement, glomerular hyperfiltration and increased synthesis of extracellular matrix. Twenty-five to 40% of diabetic patients develop microalbuminuria with a high risk of progression to overt diabetic nephropathy. Several classes of growth factors and cytokines have been suggested to be involved in mediating the adverse vascular effects of hyperglycaemia, most importantly growth hormone, insulin-like growth factors, transforming growth factors ß and vascular endothelial growth factor (VEGF) [13]. Most recently the latter has been implicated in the pathogenesis of both diabetic nephropathy and retinopathy. Overall, VEGF appears to play a central role in mediating diabetic endothelial dysfunction and vasculopathy [24]. Increasing understanding of the molecular mechanisms underlying the role of VEGF in these
