研究问题
However, the role of meniscal senescence in OA remains poorly understood.；However, the non‐metabolic role of HK2 in regulating meniscal function remains unclear.；Although these biological activities have been validated in various in vitro and in vivo models, the potential protective effects of purpurin against meniscal senescence or OA progression remain unknown.
方法
The harvested meniscus samples were sliced into smaller fragments, followed by sequential enzymatic digestion.；This process involved the use of 4 mg/mL protease (P5147, Sigma‐Aldrich) for 90 min, followed by 0.25 mg/mL collagenase P (11,213,873,001, Roche, Mannheim, Germany) for 12 h.；Quantitative real‐time PCR (qPCR) was carried out using the SYBR Green ProTaq HS Premix (AG11701, Accurate Biology) on an ABI ViiA 7 Real‐Time PCR System (Applied Biosystems, Foster City, CA, USA).；Primer sequences used for qPCR are listed in Table .
核心结论
Knee OA is frequently associated with degenerative changes in the meniscus (Figure ).；Senescence‐associated beta‐galactosidase (SA‐β‐Gal) staining revealed that the OA meniscus (OM) contained a higher proportion of senescent cells (Figure ; Figure ).；Differential gene expression analysis demonstrated that the glycolysis‐related gene HK2 was significantly upregulated in OA meniscal tissues (Figure ). ‖ 结论：Collectively, dysregulation of the HK2/MYH10/PRKN axis compromises meniscal ECM integrity and accelerates meniscal senescence and OA progression.
局限
These possibilities remain to be examined in future studies.；Future studies are warranted to directly determine whether the HK2–MYH10 axis regulates meniscus progenitor cell function and endogenous meniscal repair.；This study has several limitations that should be acknowledged.

本文核心结论来自动物模型或体外细胞学，属临床前证据，不能外推至人体。「延长健康寿命」「改善功能」等表述在小鼠中的意义，与人类临床结局之间仍有距离。
