Dietary reversal shifts microbial taxa signature in obese PN mice. A Analysis to identify differentially abundant fecal pellet bacteria with DESeq2 between HFD versus SD at 16 weeks of age or between HFD versus SD, HFD-R versus HFD, or HFD-R versus SD at 24 weeks of age (adjusted p-value < 0.05). B Overlap between gut microbial mediators in fecal pellets driving differences between dietary fat at 24 weeks (HFD versus SD, orange; HFD-R versus HFD, purple) represented as a bar plot of log₂ fold change (log₂FC). ASVs are listed with corresponding genus or family (*) level. C Overlap between KEGG pathway (level 1) mediators in fecal pellets driving differences between dietary fat at 24 weeks (HFD versus SD, orange; HFD-R versus HFD, purple) represented as a bar plot of log₂FC. D–E Venn diagrams of unique and common (D) bacterial taxa and E KEGG pathways, which change with dietary fat intake in the mouse gut. Multiple t-testing was used for pathway comparisons, and significant pathways were identified by FDR-adjusted p-value < 0.05. ASV, amplicon sequence variant; wks, weeks
