Theaflavin-3,3-Digallate Protects Cartilage from Degradation by Modulating Inflammation and Antioxidant Pathways

Figure 6

TFDG inhibits inflammation-related pathways induced by IL-1β. (a–i) The protein expressions of phosphorylated PI3K, AKT, p65, IκBα, ERK, JNK, and p38 were analyzed by western blotting. The grey values normalized with control group were quantified by ImageJ. The bar graph shows the of data (). , , , and . (j) P65 protein expressions were detected by immunofluorescence. Scale bar: 100 μm.
