Long noncoding RNAGCH1 mediates mitophagy via the PTEN‐induced kinase 1/Parkin pathway to drive chondrocyte dysfunction and cartilage degeneration in osteoarthritis

lncRNA-GCH1 regulates mitophagy in OA chondrocytes, influencing mitochondrial function and matrix degradation. Targeting lncRNA-GCH1 may offer a potential therapeutic approach for OA treatment.
