Abstract
OBJECTIVES
Doxorubicin (DOX) is a chemotherapy drug for treating malignant tumours. However, its cardiotoxicity has limited its clinical application. The Radix Aconiti Lateralis Preparata, also known as Fuzi, has been used for treating heart failure. Nevertheless, there is still a deficiency of claeity as to whether the Fuzi polysaccharide (FPS) may prevent the side effects of DOX.
METHODS
Mice were intraperitoneally administered DOX (15 mg/kg) to establish a mouse model of DOX-induced chronic cardiotoxicity (DICC). The mice were then administered different doses of FPS or enalapril intragastrically.
KEY FINDINGS
In the DOX group, the activity of CK-MB and LDH and the content of NT-proBNP in serum of mice were increased. Myocardial infiltration of inflammatory cells and cytoplasmic vacuolation occurred. Levels of NLRP3, ASC, Caspase-1, IL-1β, IL-18, IL-6, and Bax increased, whereas levels of Bcl-2, STAT3, and p-STAT3 decreased. After administering FPS (100 mg/kg and 200 mg/kg), there were reductions in CK-MB activity and NT-proBNP levels. Cytoplasmic vacuolation, interstitial infiltration of blood, and infiltration of inflammatory cells were alleviated. The changes in protein expression mentioned above were reversed.
CONCLUSIONS
FPS can protect heart function and structure in DICC mice by inhibiting NLRP3 inflammasome-mediated pyroptosis and IL-6/STAT3 pathway-induced apoptosis.
