DUSP5 suppresses interleukin-1β-induced chondrocyte inflammation and ameliorates osteoarthritis in rats

Figure 1. DUSP5 levels in normal and OA human knee articular cartilage. (A) Representative images of safranin O staining and immunofluorescence staining of DUSP5 in human knee articular cartilage from normal individuals and patients with OA. (B, D) The protein expression and quantitation of DUSP5 in human chondrocytes derived from normal individuals and patients with OA. GAPDH was used as a control. (C) Quantitation of immunofluorescence staining of DUSP5 in human knee articular cartilage from normal individuals and patients with OA. All data are expressed as mean±S.D. (n = 3). *p<0.05, **p<0.01.
