Figure 7. Effect of PU-91 + EI-12/ EI-78 on cell viability. This figure shows cell viability differences using MTT assay in AMD cells treated with P + EI-12 (A and B) / EI-78 (C and D) at 48 h and 72 h. Data (n=3) are presented as mean ± SEM and normalized to untreated (UN) AMD cybrids which were assigned a value of 1. Mann-Whitney test were used to measure statistical differences; *p≤0.05. P = PU-91; EI = Esterase Inhibitor.
