6E11 protects HAEC from cold hypoxia reoxygenation injury when treatment occurs during cold hypoxia step (a), during both cold hypoxia and reoxygenation steps (b), but not when treatment occurs during the reoxygenation step (c). Increasing concentrations (1, 3.33, 10, 33.3 µM) of 6E11, Nec-1, Nec-1s or 8A03 were added to the UW preservation solution during hypoxia or/and in PBS – 2% FBS during reoxygenation. UW corresponds to cells treated with UW preservation solution. Controls are cells not subjected to this protocol and continuously oxygenated. DMSO are cells treated with drug vehicle. The ratio of cell viability evaluated by XTT test, is calculated in comparison to the untreated control (100% of cell viability). Data shown are mean ± SD, n = 3; ANOVA and Tukey’s Multiple Comparison Test; *P < 0.05 vs UW. See Supplementary Fig. S3 for a schematic representation of the protocol.
