Effect of <i>Ganoderma lucidum</i> Polysaccharide on Antioxidative Ability of Rats with Myocardial Injury Induced by Doxorubicin

Objective: The objective is to investigate the effect of Ganoderma lucidum polysaccharide (GLPS) on the oxidative stress induced by doxorubicin (DOX) in cardiomyocytes.Methods: SD rats were divided into control group, DOX group, GLPS low dose and high dose + DOX group.SOD and MDA levels in myocardial tissue were detected in each group.The expression of related proteins in each group was detected by Western blot.Results: GLPS can increase the SOD level and decrease MDA caused by DOX (p < 0.05).GLPS can reduce the increase of p53 content caused by DOX (p < 0.05), and up regulate the antioxidant enzyme HO-1 (p < 0.05), MDM2 (p < 0.05) and Nrf2 (p < 0.05).Conclusion: Ganoderma polysaccharide can improve the oxidative stress injury of myocardial tissue induced by doxorubicin and play a protective role in myocardial tissue.
