TGFB1 and myocardial infarction: Recently, Li et al. showed that mice were treated with zerumbone (10, 20, 40 mg kg-1·day-1) or captopril (50 mg kg-1·day-1) for 28 days after MI induction, Zerumbone, a humulane sesquiterpene from S. pinnatifolia, attenuates cardiac fibrosis by inhibiting the Transforming Growth Factor-beta 1/Sma mothers against decapentaplegic (TGF-β1/Smad) signalling pathway after myocardial infarction in mice (Li et al., 2022).
