Dysosmobacter welbionis J115T–induced lipid changes in the blood. (A) Principal component analysis showing the distribution of individuals based on their plasma lipid profile. (B) Changes in PGD2. (C) Changes in 15d-PGJ2. (D) Changes in 17-HDoHE. (E) Changes in C18-2OH. (F) Changes in C14-3OH. (G) Changes in C16-3OH. (H) Changes in C18-3OH. (I) Changes in 14,15-EET. (J) Changes in 12-HETE. (K) Changes in 9-oxoODE. (L) changes in 13-oxoODE. (M) Changes in 9-HODE. (N) Changes in 10-HODE. Statistical comparisons are either HFD versus CT or HFD+J115 versus CT. Number of mice per group: 8–10. Data were analyzed using one-way ANOVA followed by Tukey’s post hoc test ∗P < 0.05; ∗∗P < 0.01; ∗∗∗P < 0.001, and ∗∗∗∗P < 0.0001. Results are represented as mean ± SEM. 15d-PGJ2, 15-deoxy-Δ12,14-prostaglandin J2; EET, epoxyeicosatrienoic acid; HDoHE, hydroxydocosahexaenoic acid; HFD, high-fat diet; oxoODE, hydroxyoctadecadienoic acid; PGD2, prostaglandin D2.
