在了解致残性遗传病Duchenne氏肌萎缩(DMD)病人的肌蜕变上,科学家们最近取得了很大进展。 1987年11月末,哈佛医学院和波士顿儿童医院的研究人员宣布,发现了DMD病人缺少一种叽肉蛋白。一年多以前,研究人员发现Du-chenne基因,此基因缺乏或改变引起DMD。正常的Duchenne基因产生关键性肌肉蛋白,研究人员将此蛋白命名为肌缩素(dystroph-in)。了解了肌缩素在正常肌细胞中的作用,就 Scientists have made great strides recently in understanding the muscle degeneration in patients with disabling genetic disease Duchenne’s Atrophy (DMD). At the end of November 1987, researchers at Harvard Medical School and Boston Children’s Hospital announced that they found a lack of a type of grilled meat protein in DMD patients. More than a year ago, researchers found the Du-chenne gene, which is lacking or altered to cause DMD. The normal Duchenne gene produces a key muscle protein, which researchers named the protein dystrophin. Understand the role of the myosin in normal muscle cells
