Figure Legend Snippet: Vaccarin prevents the activation of JAK2/STAT3, which is mediated by NOX4. (A–C) Inhibitory effect of vaccarin on JAK2/STAT3 signaling in I/R mice ( n = 6). Statistical analyses were performed using one‐way ANOVA, followed by Tukey's post hoc test. (D, E) NOX4‐overexpressing H9c2 cells were constructed through transfection with pcDNA/NOX4. The experiment was repeated three times. Statistical analyses were performed using one‐way ANOVA, followed by Dunnett's post hoc test. (F–H) H9c2 cells were transfected with an empty pcDNA3.1 plasmid (vector) or pcDNA/NOX4. After 24 h of transfection, the cells were pretreated with vaccarin (10 μM) and/or AG490 (10 μM) for 30 min, followed by H/R induction. Western blotting was conducted to determine the expression of p‐JAK2, JAK2, p‐STAT3, and STAT3. The experiment was repeated three times. Statistical analyses were performed using one‐way ANOVA, followed by Tukey's post hoc test. Data are presented as mean ± SD. * p < 0.05; ** p < 0.01; *** p < 0.001.

Figure Legend Snippet: The inhibitory effects of vaccarin on H/R‐induced oxidative stress and ferroptosis in cardiomyocytes are mediated by the NOX4/JAK2/STAT3 signaling pathway. H9c2 cells were transfected with an empty pcDNA3.1 plasmid (vector) or pcDNA/NOX4. After 24 h of transfection, the cells were pretreated with vaccarin (10 μM) and/or AG490 (10 μM) for 30 min, followed by H/R induction. (A–D) ROS and MDA production and SOD activity were determined. The experiment was repeated three times in triplicate. (E–G) The levels of Fe 2+ , GSSG, and GSH were determined. The experiment was repeated three times in triplicate. (H–J) The expression levels of SLC7A11 and GPX4 were determined. The experiment was repeated three times. Statistical analyses were performed using one‐way ANOVA, followed by Tukey's post hoc test. Data are presented as mean ± SD. * p < 0.05; ** p < 0.01; *** p < 0.001.

Figure Legend Snippet: Mechanisms underlying the cardioprotective role of vaccarin in MI/R injury. Vaccarin suppressed the myocardial I/R‐induced NOX4 expression, thus inactivating the JAK2/STAT3 signaling. The suppression of NOX4‐mediated JAK2/STAT3 signaling contributed to the antioxidative and antiferroptotic effects of vaccarin in MI/R injury.
