This study aimed to investigate the role and mechanism of FK506 binding protein 38 (FKBP38) in chondrocyte senescence and OA progression.MethodsFKBP38 expression was detected in articular cartilage from natural aging and OA mouse models. Mice with FKBP38 conditional knockout (FKBP38-cKO) and inducible conditional knockout (FKBP38-iKO) were generated for these models. An adeno-associated virus (AAV) vector overexpressing FKBP38 was injected into wild-type mouse joints. Joint damage was assessed at 8 and 18 months for natural aging or 4 and 8 weeks after DMM surgery by histology.ResultsFKBP38 expreCartilage19476035251377525https://www.ebi.ac.uk/biostudies/studies/S-EPMC12497730biostudies-literatureFKBP38 Alleviates Osteoarthritis Progression by Inhibiting Chondrocyte Senescence.PMC1249773021-220-06Liao ZWu JLi HZou ZTan XCao HChen WZhou TRao ZWang HLi KfalseFKBP38 Alleviates Osteoarthritis Progression by Inhibiting Chondrocyte Senescence.ObjectiveOsteoarthritis (OA) is a prevalent age-related degenerative joint disease characterized by cartilage degeneration, joint pain, and reduced mobility, with aging as the primary risk factor.
