TGFB1 and myocardial infarction: Ma et al. demonstrated that Danqi soft capsule (DQ), which was prepared from powdered water extracts of S. miltiorrhiza and Panax notoginseng, could inhibit infarct border zone (IBZ) remodeling and reduce susceptibility to ventricular tachyarrhythmias (VT) possibly via TGF-β1/Smad3 pathway in a rat model of post-myocardial infarction [55].
