Abstract | BACKGROUND: PURPOSE: METHODS: We used left anterior descending coronary artery ligation to construct an acute myocardial infarction model. Cardiac function, heart weight, infarction size, and histopathology were measured. Cardiomyocytes were treated with hydrogen peroxide to build an in vitro model. Cell apoptosis, fibrosis, and reactive oxygen species-related markers were tested. We observed the mitochondrial ultrastructure through transmission electron microscopy. The levels of collagens and TGF-β1 signalling were measured. The lentiviral vector containing the full-length TGF-β1 sequence was administered to investigate the rescue role of Guanxin V. RESULTS: CONCLUSIONS:
Guanxin V effectively relieved apoptosis, oxidative stress damage, and fibrosis through down-regulating the TGF-β1 signalling pathway, which enhances the knowledge of the cellular and molecular mechanism of Guanxin V in treating acute myocardial infarction.
