Abstract

<p>Purified diet has a greater impact than fiber on the serum and fecal metabolome. <b>A,</b> PCA of serum metabolomics from the B16-OVA experiment. PC, principal component. <b>B,</b> Heatmap showing log-transformed relative abundances of top 50 significant metabolites by ANOVA of the same metabolomics dataset. <b>C,</b> Volcano plots of serum metabolites in mice fed with chow vs. low–fiber-purified diet (LC_In0) and in mice fed with high–fiber (HC_In8)- vs. low–fiber (LC_In0)-purified diet (all B16-OVA tumors and anti–PD-1 treatment). FC, fold change. <b>D,</b> Venn diagram of significantly changed metabolites from the comparisons shown in <b>C</b>, showing minimal overlap between the high–fiber-purified diet and chow. For all panels, <i>n</i> = 7 to 8 mice per group.</p>
