ANXA1sp Protects against Sepsis-Induced Myocardial Injury by Inhibiting Ferroptosis-Induced Cardiomyocyte Death via SIRT3-Mediated p53 Deacetylation

Figure 5

SIRT3 inhibition attenuates the protective effects of ANXA1sp on LPS-challenged H9C2 cells. H9C2 cells were assigned to control, LPS, LPS+ANXA1sp, and LPS+ANXA1sp+si-SIRT3 groups. (a) CCK-8 for H9C2 cell viability. (b) LDH level in H9C2 cell supernatant. (c–e) ELISA for TNF-α, IL-1β, and IL-6 levels. (f–i) ROS, MDA, SOD, and GSH levels in H9C2 cell supernatant. (j) Iron accumulation in H9C2 cells. (k) WB for levels of ferroptosis-related proteins (GPX4 and FTH1). The experiments were repeated three times (). Data were presented as . All statistical analyses were performed using Student’s -test or one-way ANOVA. ; ; .
