Sex-specific cardiac dysfunction in mice with chronic kidney disease.

ABSTRACT:

Background

Cardiovascular disease (CVD) is the leading cause of death among patients with chronic kidney disease (CKD). Rodent models are widely used to study uremic CVD pathophysiology. We compared cardiac function parameters in male and female animals from two established mouse CKD models and examined associations between gut-derived uremic toxins and echocardiogram findings.

Methods

Male and female adult C57Bl/6J mice were randomly assigned to control, adenine-induced CKD and 5/6 nephrectomy CKD groups. Echocardiography was performed on all mice at age 17 weeks (5 weeks after CKD induction). Serum creatinine, cystatin C and gut-derived uremic toxins were analyzed at study termination, and RNA sequencing of left ventricle tissue was performed and analyzed.
