This study aimed the role of gold nanoparticles (AuNP) in advanced glycation end-products (AGEs) induced migration and invasion in bovine retinal endothelial cells (BRECs). BRECs were isolated from the retina. Cell viability was confirmed by the MTT assay. In vitro wound migration assay was performed to investigate the migration of BRECs. In vitro tube formation was measured by on-gel system. Apoptosis induced by AuNP was confirmed by caspase-3 assay. AGE-bovine serum albumin (BSA) demonstrated increase of cell migration and proliferation in BRECs. In addition, AuNP regardless of the existence of AGE-BSA suppressed proliferation, migration, and angiogenesis. AuNP suppressed AGE-BSA induced migration and invasion, and induced apoptosis through caspase-3. As a results, AuNP have a potential anti-angiogenic effect for AGE-induced angiogenesis in vitro and offer possibility for the treatment of diabetic retinopathy.
