Research Reveals New Genetic Links to Diabetes
Researchers in the United States and Europe have discovered a new batch of genes connected to the most common form of diabetes. In a handful of reports published Thursday in the U.S.-based journals "Science" and "Nature Genetics," the researchers say they have identified at least seven new genes that could increase a person's risk to develop Type Two diabetes. The scientists identified the genes by testing the DNA of tens of thousands of people in several countries.
Scientists hope the findings will enable them to develop new drugs to treat, or even prevent someone from developing the disease. Type Two diabetics cannot produce enough insulin, which processes sugar into energy, or cannot make efficient use of the insulin in their body. They are at risk of heart disease, kidney failure, blindness and amputations. About 200 million people around the world are affected by the disease.
美国和欧洲的研究人员发现了与一种最常见糖尿病有关的一组基因。在星期四出版的美国《科学》和《自然遗传学》杂志的若干文章中，研究人员说，他们已经确认出至少7种可以增加人类患二型糖尿病风险的新基因。科学家测试了几个国家数万人的DNA数据，确认出上述基因。
科学家希望，这个发现能让他们研制新的药物来医疗、甚至防止一些人患糖尿病。二型糖尿病患者体内不能产生足够的胰岛素或不能有效利用体内的胰导素。胰岛素把人体内的糖份转换成能量。二型尿病患者还面□
'7b心脏病、肾衰竭、失明和截肢等多种风险。全世界目前大约有2亿糖尿病患者。
