Figure 4. Western blots of vascular endothelial growth factor from p18 retinas of rats Injected with n-acetylcysteine, apocynin, or phosphate buffered saline

Western blot of vascular endothelial growth factor (VEGF) in oxygen-induced retinopathy pups treated with PBS, apocynin, and n-acetylcysteine (NAC; intraperitoneal injections once every 24 h from p12 to p17) showed no difference in VEGF protein from retinas analyzed at p18 (p=0.82, Student t-test, n=4, phosphate buffered saline (PBS) versus NAC; p=0.201, Student t-test, n=4, PBS versus apocynin). Overall ANOVA comparing three groups p=0.3120.
