Fig. 4From: Polysaccharide from Angelica sinensis attenuates SNP-induced apoptosis in osteoarthritis chondrocytes by inducing autophagy via the ERK1/2 pathwayASP-induced autophagy in chondrocytes stimulated with SNP (1 mg/ml). a Autophagy-related proteins (LC3II/I, p62, Beclin-1, Atg5) were detected by western blot. b–e The quantitative results are presented as the means ± SD of three independent experiments (n = 3). f LC3-II immunostaining. Significantly increased green bright puncta showed the formation of the autophagosomes. *p < 0.05, **p < 0.01, ***p < 0.001, #p < 0.0001, and statistical significance was determined by one-way ANOVABack to article page
