To better PR:PROJECT_SUMMARY understand how vitamin A status influences gut microbiota and host metabolism, PR:PROJECT_SUMMARY we systematically analyzed urine, cecum, serum, and liver samples from vitamin A PR:PROJECT_SUMMARY sufficient (A+) and A- mice using 1H NMR-based metabolomics, quantitative PR:PROJECT_SUMMARY (q)PCR, and 16S rRNA gene sequencing coupled with multivariate data analysis. PR:PROJECT_SUMMARY The microbiota in the cecum of A- mice showed compositional as well as PR:PROJECT_SUMMARY functional shifts compared to the microbiota from A+ mice. Targeted 1H NMR PR:PROJECT_SUMMARY analyses revealed significant changes in microbial metabolite concentrations PR:PROJECT_SUMMARY including higher butyrate and hippurate and decreased acetate and PR:PROJECT_SUMMARY 4-hydroxyphenylacetate in A+ relative to A- mice. Bacterial butyrate-producing PR:PROJECT_SUMMARY genes including butyryl-CoA:acetate CoA-transferase and butyrate kinase were PR:PROJECT_SUMMARY significantly higher in bacteria from A+ versus bacteria from A- mice. A - mice PR:PROJECT_SUMMARY had disturbances in multiple metabolic pathways including alterations in energy PR:PROJECT_SUMMARY metabolism (hyperglycemia, glycogenesis, TCA cycle, and lipoprotein PR:PROJECT_SUMMARY biosynthesis) and the A- host showed metabolites indicative of a hypermetabolic PR:PROJECT_SUMMARY state (higher levels of amino acids and nucleic acids). A- mice had PR:PROJECT_SUMMARY hyperglycemia, liver dysfunction, changes in bacterial metabolism, and altered PR:PROJECT_SUMMARY gut microbial communities. Moreover, integrative analyses indicated a strong PR:PROJECT_SUMMARY correlation between gut microbiota and host energy metabolism pathways in the PR:PROJECT_SUMMARY liver. Vitamin A regulates the microbiota, bacterial metabolism and the effects PR:PROJECT_SUMMARY of vitamin A on the microbiota results in alterations to host metabolism.
