In the present study, we aimed to investigate the effects of crocin on doxorubicin-induced cardiotoxicity in rats. Forty rats were randomly divided into four groups: (a) control [received normal saline as a dose of 1 ml/kg by intraperitoneal injection (ip) for 15 days], (b) crocin (received crocin as a dose of 40 mg/kg/24h by ip for 15 days), (c) DOX (received DOX as a dose of 2 mg/kg/48h by ip in six injection, cumulative dose 12 mg/kg), and (d) DOX+crocin (received DOX as a dose of 2 mg/kg/48h by ip in six injection, and crocin as a dose of 40 mg/kg/24h i.p for 15 days). As compared to the controls, the results showed that DOX administration caused significant increases in lipid indices [triglyseride (TG), low-dencity lipoproteins (LDL) (p<0.001), and very low-dencity lipoproteins (VLDL) (p<0.005)], oxidative stress parameters [malondialdehyde (MDA) and total oxidant status (TOS) (p<0.001)] and cardiac markers [creatine kinase-muscle/brain (CK-MB) and cardiac troponin I (cTnI) (p<0.001)]. Besides, significant decreases in antioxidant defense systems [glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), and total antioxidant status (TAS) (p<0.001)] were observed. The present study also demonstrated that co-administration of crocin with DOX significantly ameliorated the lipid profile (p<0.005), cardiac markers (p<0.005), and oxidative stress indices (p<0.001) as compared to DOX group. Histopathologically, significant increase in the mean histopathological damage score (MHDS) was found in the DOX group as compared to the controls (p<0.001). In contrast, the administration of crocin with DOX alleviated MHDS in myocardium (p<0.001). Taken together, our results reveal that crocin might be a cardioprotective agent in DOX-treated patients for cancer.eninfo:eu-repo/semantics/openAccessDoxorubicincrocinapoptosisoxidative stressmyocardial toxicityArticle10.1007/s11356-021-15409-w2-s2.0-85111500058658134634322808Q16580228WOS:000678513500039Q2
