Figure 6. Neuroprotection of resveratrol blocked by sirtinol, a sirtuin 1 inhibitor. The numbers of retinal ganglion cells (RGCs) in eyes co-injected with resveratrol and sirtinol were smaller than injected with resveratrol at 1 week after treatment with concentrations of 9.4 uM and 31.3 uM of resveratrol (n≥5 for each group, *p<0.05, Mann-Whitney test, error bars represent standard deviation).
