Metabolic memory in diabetic foot syndrome (dfs): epigenetic changes of the expression of micro-rnas and single nucleotide polymorphisms (snps) frequency in a cohort of diabetic patients with and without foot ulceration and correlation with indices of endothelial and adipo-inflammatory dysfunction

Background: Diabetic foot is a significant cause of morbidity in diabetic patients, with a rate that is approximatelytwice that of patients without foot ulcers. “Metabolic memory” represents the epigenetic changes induced by chronic hyperglycaemia, despite the correction of the glucose levels themselves. These epigenetic modifications appear to perpetuate the damage caused by persistently elevated glucose levels even in their absence, acting at various levels, mostly affecting the molecular processes of diabetic ulcer healing. Methods: The aim of our cross-sectional study was to analyse a cohort of patients with diabetes with and without lower limb ulcers. We examined the effects of epigene…
