摘要

Diabetes is characterized by hyperglycemia; spontaneous degradation of glucose leads to the production of reactive intermediates including glyoxal [1]. Glucose and glyoxal react non-enzymatically with proteins to form advanced glycation end products (AGEs). Hyperglycemia increases AGE levels, and AGEs contribute to impaired wound healing in diabetics [2]. The epidermal growth factor receptor (EGFR) and its downstream effector, Snai2, are important mediators of wound reepithelializa-tion. Although expression of EGFR transiently increases at wound margins in healthy tissue, there is decreased expression in chronic, non-healing wounds [3].
