Effects of cycloastragenol against the mitochondrial dysfunction in an Aβ-induced mouse model of Alzheimer’s disease. (a,b) Western blot results of Bax, Bcl-2, cleaved Caspase-3, and Bim in the experimental mice’s brains, with respective bar graphs. (c,d) Immunofluorescence analysis of Caspase-3 and Bim in the cortex and hippocampus of experimental mice, with respective bar graphs. The p-value < 0.05 was considered a significant difference. * showing a significantly different from the control group; # significantly different from the Aβ-injected group. Significance = * p < 0.05; # p < 0.05. CAG 20: Cycloastragenol 20 mg/Kg, Aβ: Amyloid beta, DAPI: 4′,6-Diamidino-2-phenylindole, CAG: Cycloastragenol, ns: non-significant difference.
