Fig. 3From: Astaxanthin attenuates cognitive deficits in Alzheimer’s disease models by reducing oxidative stress via the SIRT1/PGC-1α signaling pathwayRepresentative images of Bcl-2, Bax, SIRT1, and PGC-1α immunofluorescence staining of three hippocampal subregions (CA1, CA3, and DG) (magnifification × 400; scale bars = 100 μm) and their quantitative analysis in A–C. *P < 0.05, Control group vs. Aβ group and Aβ + AST + NAM group. #P < 0.05, Aβ + AST group vs. Aβ + AST + NAM group. &P < 0.05, Aβ + AST group vs. Aβ group.
