Implications of NAD+ Metabolism in the Aging Retina and Retinal Degeneration

Figure 3

Inhibition of NAMPT activity affects mitochondrial biogenesis in human retinal pigment epithelial cells. Human retinal pigment epithelial cells were treated with 1 μM FK866 for 72 hours, and change in mRNA expression of PGC1a and Nrf1 and density of healthy respiring mitochondria (MitoTracker Green positive) were determined using qPCR and FACS analysis, respectively. Results are expressed as for independent experiments. vs. control. PGC-1α: peroxisome proliferator-activated receptor gamma coactivator 1-alpha; Nrf1: nuclear respiratory factor 1.
(a) PGC-1α
(b) Nrf1
