Cytoprotective Effect of Dietary Squalene Supplementation on Experimentally Induced Cardiomyopathy in Rats

Background: Adriamycin is a broadspectrum, potent, older chemotherapy drug and antineoplastic agent used in the treatment of several cancers such as solid tumours, leukaemias, and lymphomas, playing a major role in cancer chemotherapy. Long-term use of this drug results in congestive heart failure and to overcome this effect dietary squalene intake reduces the adverse effects of adriamycin-mediated cardiotoxicity and cellular oxidative stress. Methods: The current study aims to investigate the cytoprotective effects of dietary squalene supplementation on adriamycin-induced cardiomyopathy in rats in terms of alterations in Troponin T, homocysteine, diagnostic marker enzymes, and cardiac tissue histology. Results: The findings show that a 1.5 percent dose of dietary squalene supplementation for 21 days reduced adriamycin-induced changes in homocysteine, troponin T, diagnostic marker enzymes, and lesions in cardiac tissues. Conclusion: The outcomes of the study specified squalene's cytoprotective action which stabilizes membranes against adriamycin-induced oxidative membrane degradation, which is primarily responsible for heart cell irreversible necrosis.
