The effects of XJB and TSM on ferroptosis in H9c2 cells. Different concentrations of XJB (A) and TSM (B) in the presence or absence of 0.5 µM RSL3. Cell death was calculated from the measurements by the Alamar Blue cell viability assay, and data are presented as a percentage of the control. GPX4 protein levels were calculated based on densitometry analysis using LI-COR Image Studio Lite and normalized to β-actin expression for each band. Data are presented as a percentage of the control group. ⁺⁺ p < 0.01 vs. control; * p < 0.05 and ** p < 0.01 vs. RSL3. n = 3 per group.
