Fig. 4From: The protective effect of kirenol in osteoarthritis: an in vitro and in vivo studyEffect of kirenol on IL-1β-induced NF-κB signaling pathway activation. The protein expression of p65 in nuclear and IκBα in cytoplasm on chondrocytes treated as above were visualized by western blot (A), and quantified in (B). C The nuclei translocation of p65 was detected by the immunofluorescence combined with DAPI staining for nuclei (scale bar: 10 µm). The data presented are the means ± S.D. *p < 0.05, and **p < 0.01, one-way AVOVA, n = 6Back to article page
