Effects of Astragaloside treatment on HIF-1α, Notch1 and Jagged1 protein expression levels. Representative western blotting images and quantification of (A) HIF-1α, (B) Notch1 and (C) Jagged1 protein expression levels. GAPDH served as an internal control. Data are expressed as the mean ± standard deviation (n=6). 1, sham control group; 2, myocardial infarction model group; 3, 2.5 mg/kg/day Astragaloside treatment group; 4, 10 mg/kg/day Astragaloside treatment group; MI, myocardial infarction; AST, Astragaloside; HIF-1α, hypoxia-inducible factor 1-α.
