Abstract
An altered expression of the apamin-sensitive K+ channel from skeletal muscle is apparently implicated in human myotonic dystrophy (MD). We found, in rats, that the expression of this channel depends on age and the type of muscle. This result may be one of the bases of the different susceptibilities of fast and slow muscles to drug-induced myotonia.
摘要
骨骼肌中蜂毒明肽敏感钾通道的表达改变显然与人类强直性肌营养不良（MD）有关。我们发现，在大鼠中，该通道的表达取决于年龄和肌肉类型。这一结果可能是快肌和慢肌对药物诱导的肌强直敏感性不同的基础之一。
