Gene Could Lead to New Treatments for Age-Related Macular Degeneration and Diabetic Retinopathy
基因可能会成为治疗老年性黄斑变性和糖尿病视网膜病变的新型方法
March 17, 2008 -- New research shows that a gene called Robo4 could help curb or prevent two leading causes of blindness: age-related macular degeneration (AMD) and diabetic retinopathy.
新的研究表明Robo4基因有助于治愈或阻止导致失明的两大病因:老年性黄斑变性(AMD)和糖尿病视网膜病变。
"This discovery has significant implications for developing drugs that activate Robo4 to treat AMD and diabetic retinopathy," Kang Zhang, MD, PhD, University of Utah associate professor of ophthalmology and visual sciences, says in a news release.
Utah大学眼科学副教授Kang Zhang在新闻中说:“这项发现对于开发活化Robo4基因的药物(用来治疗AMD和糖尿病视网膜病变)具有重要意义。”
The Robo4 gene isn't about the eyes. Instead, it plays a role in the development of new blood vessels.
Robo4基因并非与眼睛相关,相反,该基因在新生血管的分化中起重要作用。
In diabetic retinopathy and in some AMD patients, certain blood vessels in the eye become leaky and abnormal new blood vessels develop.
糖尿病视网膜病变和一些AMD患者其眼睛的血管通透性变大且有异常的新生血管分化。
Activating the Robo4 gene shored up leaky blood vessels and curbed the development of new blood vessels, Zhang's team found in a series of experiments in test tubes and mice.
Zhang研究小组在一系列的试管实验和小鼠实验中发现活化的Robo4基因可以支持渗漏的血管,抑制新生血管的分化。
To do that, the Robo4 gene countered a chemical called vascular endothelial growth factor (VEGF), which signals the creation of new blood vessels. In other words, Robo4 prevented VEGF from issuing the "let's make some blood vessels" order.
Robo4基因抑制一种叫做血管内皮生长因子(VEGF)的化学物质,该物质可以传递产生新生血管的信号。换言之,Robo4基因阻止VEGF发出“让我们来产生一些新生血管”的命令。
Those experiments "may have broad therapeutic potential," the researchers write in the March 16 advance online edition of Nature Medicine.
研究人员在自然医学3月16进展在线版上说那些实验“可能会扩大治疗潜能。”
