mdx小鼠缺乏肌营养不良蛋白,具有杜氏肌营养不良症的组织学特征,但在生命的第一年几乎没有虚弱。我们在这里报告了自愿轮跑的早期缺陷,这是用计算机化的轮子进行测定的。所有 mdx 小鼠均表现出间歇性跑步模式,与对照组中的连续跑步相反。在所有测试年龄(5-21 周)的 mdx 小鼠和对照小鼠之间,平均连续跑步时间存在显着差异。该测定是非侵入性的,具有无偏见的自动数据收集的优点,并且对于量化治疗研究中的 mdx 缺陷应该有用。 (C) 2002 约翰·威利儿子公司
The mdx mouse lacks dystrophin and has histological features of Duchenne muscular dystrophy but little weakness in the first year of life. We report here an early deficit in voluntary wheel running, as assayed with a computerized wheel. All mdx mice showed an intermittent running pattern, in contrast to the continuous running seen in controls. The average continuous running time differed significantly between mdx and control mice at all ages tested (5-21 weeks). This assay is noninvasive, has the advantage of unbiased automatic data collection, and should be useful for quantifying the mdx deficit in therapeutic studies. (C) 2002 John Wiley Sons, Inc.
