Emodin suppresses OGD/hypoxia-induced cell death in PC12 cells: Cell viability was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. (A) Comparison of cell viability between normoxia and OGD-hypoxia at different time points. (B) Cell viability with different doses of Emodin. (C) The protective effect of Emodin under OGD/hypoxia. Data represent SEMs of three independent experiments. ** p < 0.01, *** p < 0.001 using Student’s t-test.
