As a devastating complication, diabetic foot ulcer (DFU) is characterized by chronic, nonhealing wounds due to vasculopathy and neuropathy. It has emerged as a most challenging chronic disease worldwide, affecting millions of people worldwide. The higher mortality and disability rates urgently require innovative therapeutic strategies. Recently, different from nanotechnology, metabolic reprogramming is believed to be associated with the occurrence and progression of various diseases (including cancer, obesity and neurodegenerative diseases). They can alter their cellular metabolism (involving glucose, lipid, and amino acid metabolism) to cope with different external stimuli and pressures. As a novel potential strategy, metabolic reprogramming also exhibits great potential to improve the wound healing of DFU. This review aims to summarize the current knowledge, biological characteristics, and underlying mechanisms of metabolic reprogramming in DFU. And we propose their potential therapeutic implications to improve wound healing and prevent complications in DFU. In addition, we also highlight the current challenges and the future perspectives.
