Loss of NAMPT in aging retinal pigment epithelium reduces NAD+ availability and promotes cellular senescence
Figure 5. Time-dependent decline in NAD+ content and induction of senescence in human retinal pigment epithelial cells treated with FK866. Human retinal pigment epithelial cells (ARPE-19) were treated with 10μM FK866 for 24, 48 and 72 hr. Time-dependent changes in (A) NAD+ content (B) cell viability and (C-D) senescence of FK866 treated human RPE cells were evaluated. Data are presented as mean ± S.E.M for n=3 independent experiments. *p<0.05 compared to CON (Vehicle treated).
