| English abstract | Cardiorenal syndrome is a life-threatening condition. The aim of the current study was to determine the cardioprotective effects of amlexanox in 5/6 nephrectomized rats. Rats were randomly assigned to three groups: sham, 5/6 nephrectomized rats, and amlexanox-treated 5/6 nephrectomized group. Amlexanox (25 mg/kg/day, i.p.) administration was started just after surgery and continued for 10 weeks. After treatment, kidney function (serum creatinine and urea) and blood pressure (systolic and diastolic) were measured. Heart weight (normalized to tibial length) and fibrosis area percentage were measured. Serum brain natriuretic peptide (BNP, heart failure marker) and cardiac levels of β1-adrenergic receptor (β1AR), β-arrestin-2, phosphatidylinositol-4,5-bisphosphate (PIP2), diacylglycerol (DAG), pS473 Akt (a survival marker), and caspase-3 activity (an apoptosis marker) were also measured. The 5/6 nephrectomy caused renal impairment, cardiac fibrosis, apoptosis, and heart failure indicated by down- regulation of cardiac β1AR down-stream signals compared with those in the sham group. Interestingly, amlexanox significantly reduced all cardiopathological changes induced after 10 weeks of 5/6 nephrectomy. Amlexanox showed potent cardiac antifibrotic and antiapoptotic effects in 5/6 nephrectomized rats, which were associated with reduced heart failure. To our knowledge, this is the first study that addresses the potent in vivo cardioprotective effects of amlexanox |
