PU-91 drug rescues human age-related macular degeneration RPE cells; implications for AMD therapeutics

Figure 3. PU-91 alters mitochondrial GFP fluorescence intensity. Untreated (AMD UN) and PU-91-treated AMD cybrids (AMD PU-91) were stained with CellLight mitochondrial GFP stain followed by confocal imaging of cells. (A) Shows representative bright-field, DAPI, mtGFP, and overlay (DAPI + mtGFP) confocal images. PU-91-treated AMD cybrids had a drastic increase in mtGFP fluorescence intensity compared to the untreated group (p≤0.05, n=3) (B). 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.
