The progression of DR is closely related to the excessive production and accumulation of advanced glycation end products (AGEs) in the retinal microvasculature. AGEs can stimulate the proliferation and migration of endothelial cells, leading to abnormal angiogenesis and neovascularization, which are key sources of vision loss in diabetic patients. β2-glycoprotein 1 (β2GP1) is a serum glycoprotein that plays a critical role in regulating the pathophysiology of diabetes and its complications, including DR. Previous studies have suggested that β2GP1 can inhibit the formation of AGEs and reduce the risk of DR. However, the mechanism underlying this effect remains unclear.讨论目的：The present study aims to investigate the effect of β2GP1 on the progression of DR and the underlying mechanism. Specifically, we will examine the impact of β2GP1 on endothelial cell proliferation, migration, and angiogenesis in vitro and in vivo. We hypothesize that β2GP1 can inhibit the hyperglycemia-induced neovascularization in the diabetic retinas by suppressing the AGEs-mediated signaling pathways.讨论方法：We will first analyze the expression of β2GP1 in the serum and retinas of diabetic mice using western blotting and immunofluorescence staining. Next, we will assess the effects of β2GP1 on endothelial cell proliferation, migration, and tube formation in vitro under hyperglycemic conditions. We will also investigate the role of the AGEs-mediated signaling pathways in these processes using specific inhibitors and siRNA knockdown techniques. Finally, we will examine the therapeutic potential of β2GP1 in a mouse model of DR by assessing its impact on retinal vascular leakage, neovascularization, and functional damage.精品文档---下载后可任意编辑预期结果：We anticipate that our study will provide novel insights into the anti-angiogenic effect of β2GP1 in DR and the underlying mechanisms. We expect that β2GP1 can decrease the production and accumulation of AGEs in the retinal microvasculature, thereby inhibiting endothelial cell proliferation, migration, and angiogenesis in vitro and in vivo. This study may shed light on the development of effective therapeutic approaches to prevent or treat DR and other diabetic complications.
