Doxorubicin, an antibiotic belonging to anthracycline family, has been used for treatment of malignancies. Cardiotoxicity is the main adverse effect of doxorubicin. Apigenin, as a flavonoid, has antioxidant, anti-inflammatory and anti-tumoral properties. The aim of this study was the assessment of any protective effect of apigenin on cardiotoxicity induced by doxorubicin.40 male Wistar rats were randomly divided into 4 groups: control, cardiotoxicity (DOX), apigenin treated group (DOX + Api 25) and apigenin group (Api 25). At the end of the experiment, the markers of cardiac function (%EF, %FS, LVIDs, LVIDd), cardiac and liver injury (LDH, CK-MB, cTn-I, ALT, and AST), cardiac apoptosis (Bax, Bcl-2 and Caspase3), cardiac oxidative stress (SOD, GSH, MDA) and cardiac fibrosis were measured.Apigenin improved cardiac functional parameters. The levels of cardiac and liver injury markers were significantly decreased in DOX + Api 25 compared to DOX. Treatment with apigenin caused significant decrease in percentage of cardiac fibrosis in comparison with DOX. Apigenin in DOX + Api 25 group led to significant decrease in apoptotic proteins (Casp3, Bax) and a significant increase in anti-apoptotic proteins (Bcl2). In apigenin treatment groups, SOD levels significantly increased while a significant decrease was observed in MDA. The amount of GSH in DOX + Api 25 had no significant change in comparison to control and Api 25 groups.Apigenin reduced cardiac injuries induced by DOX through anti-fibrotic, antioxidant and anti-apoptotic properties. It seems that apigenin prevents cardiac injuries and improves cardiac function.
