AGEs (Advanced Glycation End-products) in Bone Come of Age

Advanced Glycation End-products (AGEs) are seen in long-lived proteins and were not expected to accumulate in the bone that turnovers and renews itself. Here, we provide a commentary on the contrary, highlighting the Special Issue of AGEs in Bone. An outcome of hyperglycemia and increased oxidative stress, AGEs form and accumulate by altering the bone resorption and formation processes. Accumulation of various AGEs species in bone increases bone fragility through the stiffening of the collagen network and, potentially, through the changes in collagen-mineral interactions. Evidence from both preclinical and clinical studies is leading to new translational approaches wherein measurement, inhibition, or removal of AGEs show the potential to diagnose, manage, and treat bone fragility associated with multiple conditions and diseases.
