Abstract:Objective To investigate expression and significance of IL24 gene in the knee osteoarthritis (KOA), and to provide scientific basis for early diagnosis and gene therapy for knee osteoarthritis. Methods Fresh synovial specimens were collected from orthopedic patients in our hospital. Trizol was used to extract total RNA. Expression of IL24 in knee osteoarthritis synovium was detected by RT-PCR. Results IL24 gene expression in knee KOA synovial tissue obviously decreased (P < 0.01). Conclusions IL24 expression in the synovium of osteoarthritis knee joint obviously declines and is negatively correlated with the progress of KOA. Therefore, it can provide a reference for future diagnosis and gene therapy of knee osteoarthritis.
