Figure 1. Adiponectin and its receptors expression in the retina and the retinal pigment epithelium-choroid in humans. A: Picture represented Adiponectin (APN) protein levels in the retina and the retinal pigment epithelium (RPE)-choroid in human eyeballs. The protein levels of APN in the retina were lower than in the RPE-choroid (n=7, *p<0.05). B, C: Picture represented Adiponectin receptors (AdipoR1 and AdipoR2) messenger RNA (mRNA) expression in the retina and the RPE-choroid in human. The adiponectin receptors (AdipoRs) mRNA levels in the retina were much lower than those in the RPE-choroid (n=14, ***p<0.001). D: Picture represented the AdipoRs protein levels in the retina and the RPE-choroid in human as determined with western blotting. E: Picture represented densitometry analysis of the AdipoRs protein levels in the retina and the RPE-choroid in human. AdipoR1, and AdipoR2 protein expression in the RPE-choroid were higher than in the retina (n=6, *p<0.05).
