Age-related macular degeneration (AMD) is a degenerative disease of the retina where the molecular mechanism involves the production of vascular endothelial growth factor (VEGF), a factor of poor prognosis of the progression of the disease. Previous studies have shown that resveratrol, a polyphenol of grapevines, can prevent VEGF secretion induced by stress from retinal cells. Considering the fundamental role played by VEGF in development and progression of AMD, we investigate the potential effect of red wine extract (RWE) on VEGF secretion and its signaling pathway in human retinal cells ARPE-19. To examine the effect of RWE in ARPE-19, a quantitative and qualitative analysis of the RWE was performed by HPLC MS/MS. We show for the first time that RWE decreased VEGF-A secretion from ARPE-19 cells and its protein expression in concentration-dependent manner. RWE-induced alteration in VEGF-A production is associated with a down of VEGF-receptor 2 (VEGF-R2) protein expression and its phosphorylated intracytoplasmic domain. Subsequently, the activation of kinase pathway is disturbing and RWE prevents the phosphorylation of MEK and ERK 1/2 in human retinal cells ARPE-19. Finally, this study sheds light on the interest that the use of polyphenolic cocktails could represent in a prevention strategy.

红酒提取物抑制视网膜 ARPE-19 细胞中 VEGF 的分泌及其信号通路,从而可能破坏 AMD

年龄相关性黄斑变性 (AMD) 是一种视网膜退行性疾病,其分子机制涉及血管内皮生长因子 (VEGF) 的产生,血管内皮生长因子 (VEGF) 是疾病进展预后不良的一个因素。先前的研究表明,葡萄藤中的一种多酚白藜芦醇可以防止视网膜细胞压力引起的VEGF分泌。考虑到 VEGF 在 AMD 的发展和进展中所起的基本作用,我们研究了红酒提取物 (RWE) 对人视网膜细胞 ARPE-19 中 VEGF 分泌及其信号通路的潜在影响。为了检查 RWE 在 ARPE-19 中的影响,通过 HPLC MS/MS 对 RWE 进行了定量和定性分析。我们首次表明 RWE 以浓度依赖性方式降低 ARPE-19 细胞的 VEGF-A 分泌及其蛋白质表达。RWE 诱导的 VEGF-A 生成改变与 VEGF 受体 2 (VEGF-R2) 蛋白表达及其磷酸化胞质内结构域的下降有关。随后,激酶途径的激活受到干扰,RWE 阻止了人视网膜细胞 ARPE-19 中 MEK 和 ERK 1/2 的磷酸化。最后,这项研究揭示了使用多酚鸡尾酒可能代表预防策略的兴趣。激酶通路的激活令人不安,RWE 阻止人视网膜细胞 ARPE-19 中 MEK 和 ERK 1/2 的磷酸化。最后,这项研究揭示了使用多酚鸡尾酒可能代表预防策略的兴趣。激酶通路的激活令人不安,RWE 阻止人视网膜细胞 ARPE-19 中 MEK 和 ERK 1/2 的磷酸化。最后,这项研究揭示了使用多酚鸡尾酒可能代表预防策略的兴趣。
