Abstract
Sarcopenia is an age-related condition characterized by a decrease in muscle mass and a decline in muscle strength.Sarcopenia increases the risk of falls,severely affecting the quality of life of patients,and it may be associated with various age-related chronic diseases.Advanced glycation end products(AGEs)are a class of stable glycation products produced by condensation,rearrangement,cleavage,and oxidative modification between the free amino groups of proteins,lipids or nucleic acids and the free carbonyl groups of reducing sugars.Studies have revealed associations of AGEs with muscle mass,muscle strength,and sarcopenia.AGEs can lead to hardening of the extracellular matrix of skeletal muscle through glycation cross-linking.The binding of AGEs to receptors induces inflammation and oxidative stress,consequently resulting in decreases in muscle mass and muscle strength.Therefore,AGEs may play a role in the occurrence and development of sarcopenia.This review summarizes the role of AGEs in the pathogenesis of sarcopenia,offering theoretical support for probing into the mechanisms underlying sarcopenia.
