(A) Principal component analysis of bacterial composition, (B) relative abundance of bacterial genera, (C) enhanced volcano plot of bacterial genera that were differentially abundant in males of Cohort A (negative x-axis) and males of Cohort B (positive x-axis), (D) enhanced volcano plot of bacterial genera that were differentially abundant in females of Cohort A (negative x-axis) and females of Cohort B (positive x-axis), and (E) alpha diversity indices (richness, Fisher’s alpha, Shannon’s index, Pielou’s evenness) of bacteria in CD-1 mice. For colonic bacterial analysis, fecal samples were collected at ten months of age from a subset of mice from each diet group (n = 2-5/diet/sex, n = 28-31/cohort). NS = not significant and < log2(fold change), Log2 FC = > log2(fold change), P-value and log2 FC = > log2(fold change) and P < 0.05, * = P < 0.05, ** = P < 0.01, *** = P < 0.001.
