Figure Lengend Snippet: Arctiin’s role in counteracting IL-1β-induced inflammatory and ECM deterioration in chondrocytes. ( A , B ) Immunofluorescence imaging of Collagen II and MMP13 post-treatment; scale bar: 100 μm. ( C , D ) Fluorescence intensity quantification for Collagen II and MMP13 using ImageJ. ( E , F ) mRNA levels of COX-2, MMP3, MMP13, Collagen II and SOX9quantified via RT-PCR. ( G , H , I ) Protein expression and quantitative analysis of COX-2, MMP3, MMP13, Collagen II and SOX9, performed by Western blotting. Data are presented as means ± SD. Significant differences indicated by # P < 0.05, ## P < 0.01, ### P < 0.001 compared to control, and * P < 0.05, ** P < 0.01, *** P < 0.001 compared to the IL-1β-treated group; n = 3.
Article Snippet: The study utilized primary antibodies targeting MMP3, MMP13, COX-2, Collagen II, and SOX9, which Affinity Biosciences, OH, USA provided.
