Western blot analysis showed that the expression of bace1 in the AD+NS group was significantly increased compared with that in the WT+NS group (WT+NS vs. AD+NS, 1.00 ± 0.22 vs. 1.65 ± 0.24, p = 0.003); the expression of bace1 in the AD+Dex group was significantly decreased compared with that in the AD+NS group (AD+Dex vs. AD+NS, 1.11 ± 0.30 vs. 1.65 ± 0.24, p = 0.03, n = 6 in each group; Figures 6A,C). The gene discussed is BACE1; the disease is Alzheimer disease.
