Proteins that were upregulated in our study and in experimental retinal vein occlusion included fibronectin, annexin A1, galectin-3, alpha-crystallin B chain, vimentin, annexin A2, STAT1, GFAP, osteopontin, vitronectin, and clusterin [21,22]. This evidence concerns the gene ANXA1 and retinal vein occlusion.
