ABSTRACT
Objective To investigate the role of PI3K/AKT and ERK1/2 signaling pathways in the process of cardiomyopathy induced by doxorubicin(DOX).Methods Twenty SD rats were divided into two groupsDOX group(10 rats that were injected through caudal vein with 2.5 mg/kg DOX,once a week,for 6 weeks)and control group(10 rats).At 5th week after the end of DOX injection,the structural changes and functional damage were examined,and the apoptosis rate of cardiomyocytes and the expression levels of p-AKT and p-ERK1/2 were determined.Results Eleven weeks after the DOX injection,the myocardial pathological changes were mainly myofibrillar loss and cytoplasmic vacuolization.DOX could induce compensated heart function(the value of FS% was 34,P0.05)and Bax to 338%(P
