SIRT1 Downregulation by Advanced Glycation End Products Activates RANKL-Dependent Osteoclast Signaling and Drives Chondrocyte Senescence During Osteoarthritis Development

Multi-omics analysis reveals how cellular aging and sugar damage trigger bone loss in osteoarthritis, pinpointing a potential intervention pathway.

Using multi-omics + ML-assisted network analysis, proteomic and transcriptomic integration, and in vivo validation, this study identifies SIRT1 downregulation by advanced glycation end products (AGEs) as a central mechanism linking metabolic aging to osteoclast activation and chondrocyte senescence in osteoarthritis. The AGE-RAGE-SIRT1-RANKL axis is proposed as a targetable pathway for age-related OA progression.
