Figure 5. PU-91 regulates apoptotic cell death – Caspase-3/7 staining. (A) Shows representative IncuCyte live-cell images of untreated (AMD UN) and PU-91-treated AMD cybrid cells (AMD PU-91) stained with NucLight Red and Caspase-3/7 Green reagent. (B) Shows quantitation graphs for the 48 h and 72 h time points. Data are presented as mean ±SEM and normalized to untreated (UN) AMD cybrids which were assigned a value of 1. Mann-Whitney test was used to measure statistical differences; *p≤0.05.
