The two-way ANOVA results are displayed in Additional file 1: Table S3. The italics and the asterisk (*) indicate a significant (p ≤ 0.05) difference between AngII and vehicle-treated cohorts, within each genotype (Tukey’s multiple comparisons test). The italics and the dagger (†) indicate a significant (p ≤ 0.05) difference between AngII-treated animals of different genotypes (Tukey’s multiple comparisons test).
