Figure 6. Effects of aging on protein expression of eNOS in the aortas of wild-type (WT) littermates and eAPP−/− mice. Western blot results are the relative densitometry compared with β-actin protein (n=10 per group). All results are representing box plots with whiskers showing the median, 25th to 75th percentiles, and min-max range. * P<0.05 versus young mice of same strain (two-way ANOVA followed by Tukey’s HSD test).
