Abstract Introduction Cardiovascular disease (CVD) mortality is significantly higher in chronic kidney disease (CKD) patients, with vascular calcification and atherosclerosis proving to be major contributors. Endothelial dysfunction is an early marker of atherosclerosis, triggered by oxidative stress and reduced nitric oxide production. The uremic toxin indoxyl sulphate (IS), a protein-bound non-dialyzable molecule derived from dietary tryptophan that accumulates in the blood of CKD patients, activates the aryl hydrocarbon receptor (AhR) promoting downstream cytochrome P450 1A1 (CYP1A1) expression mediating oxidative stress and potentially ..
