Data of survival rate percent of intact neurons represents the mean ± SD of 3 mice per group and data of amyloid plaques represents the median and range of 3 mice per group; significantly different from sham control group at p <0.05, significantly different from sham control group at p <0.01, significantly different from sham control group at p <0.001, significantly different from sham control group at p <0.0001, #significantly different from STZ group at p <0.05, ## significantly different from STZ group at p <0.01, ### significantly different from STZ group at p <0.001, #### significantly different from STZ group at p <0.0001 using one-way ANOVA followed by Tukey’s multiple comparisons test for statistical analysis of survival rate, and using Kruskal–Wallis one-way ANOVA followed by Dunn’s multiple comparisons test for statistical analysis of amyloid plaque number.
