Fig. 8From: Perturbed gut microbiome and fecal and serum metabolomes are associated with chronic kidney disease severityProposed mechanism of perturbed gut microbiome together with fecal and serum metabolites in pathogenesis of CKD progression. Perturbation of CKD severity-related gut microbiotas may interact with disbalanced toxic and pro-oxidant metabolites from arginine and proline metabolism, arachidonic acid metabolism, ubiquinone and other terpenoid-quinone biosynthesis, and glutathione metabolism to accelerate disease progression. Red arrow indicates upregulation; black arrow indicates downregulation. LTB4, leukotriene B4Back to article page
