This study aimed to explore the effects of Wenyang Zhenshuai granules (WZG) on the morphology of cardiomyocytes, cell viability, and the expression of key mitochondrial autophagy proteins in the doxorubicin-induced model of H9c2 cardiomyocyte injury. Cardiomyocytes were cultured for 44 h and divided into 4 groups: intact control, doxorubicin-injured cells (DOX), doxorubicin-injured cells treated with WZG (DOX+WZG), and doxorubicin-injured cells treated with valsartan (DOX+valsartan; reference group). The morphology of cardiomyocytes was analyzed under an inverted microscope; cardiomyocyte survival rate was determined by MTT assay. The expression of the key mitochondrial autophagy proteins (PINK1, parkin, LC3-II, and prohibitin-2) was analyzed by Western blotting. WZG down-regulated the expression of the key mitochondrial autophagy proteins in DOX-injured cells, which may be one of the important mechanisms for regulating ventricular remodeling and cardiomyocyte apoptosis.
