Figure Lengend Snippet: Exacerbation of OA progression in miR-221/222 cluster KO mice. ( A ) X-ray images of mouse joints 8 weeks post-DMM showing increased osteophytes, irregular joints, and pronounced joint stenosis in the KO + DMM group compared with the WT + DMM group. ( B-F ) Histological staining of joint sections at 8 weeks post-DMM confirms more severe degradation of cartilage and synovial fibrosis in the KO + DMM group ( n = 5 independent biological samples). ( G-K ) Western blot analysis indicates elevated type I collagen expression ( G ), while immunofluorescence analysis shows reduced COL2A1 levels ( H , I ) and increased MMP-13 expression ( J , K ) in KO + DMM joints at 8 weeks post-surgery ( n = 3 independent biological samples). For all the graphs, the values represent the mean ± SEM. p values were calculated via one-way ANOVA, followed by Tukey’s post hoc test
Article Snippet: After that, cells were incubated with anti-MMP-13 or COL2A1 antibodies (Both 1:500, Bioss), followed by FITC-conjugated goat anti-rabbit IgG (1:500, Proteintech).
Techniques: Staining, Western Blot, Expressing, Immunofluorescence
