Figure 2. The expression of ALDH2 in the young group, aged (DMSO) group and aged (Alda1) group. (A, B) A typical ALDH2 WB image and the expression of ALDH2; (C, D) A typical ALDH2 immunofluorescence image and the expression of ALDH2. All analyses were performed in duplicate. Scale bar: 50 μm. Values are presented as the mean ± SD, n = 4 mice per group. *P<0.05: aged (DMSO) group and aged (Alda1) group vs young group; #P<0.05: aged (Alda1) group vs aged (DMSO) group.
