Inhibition of CYP1B1 ameliorates cardiac hypertrophy induced by uremic toxin

Cardiovascular disease is the predominant complication and leading cause of mortality in patients with chronic kidney disease (CKD). Previous studies have revealed that uremic toxins, including indoxyl sulfate (IS), participate in cardiac hypertrophy. As a heme‑thiolate monooxygenase, cytochrome P450 family 1 subfamily B member 1 (CYP1B1) is able to metabolize arachidonic acid into hydroxyeicosatetraenoic acids, which are thought to serve a central function in the pathophysiology of the cardiovascular system. However, whether CYP1B1 is involved in cardiac hypertrophy induced by uremic toxins remains unknown. The present study revealed that the expression of the CYP1B1 gene was significantly (P
