With Regard to the Expression Status of Sarcolemmal Aquaporin 4 in Human Muscular Dystrophies

Neurology and Clinical Neuroscience, EarlyView.
ABSTRACT Human muscular dystrophies are inherited muscle‐wasting diseases caused by the various kinds of gene mutations. Among them, Duchenne muscular dystrophy (DMD) is a representative type. Before the discovery of the causative dystrophin gene of DMD, the fragile myofiber plasma membrane was thought to be the trigger of myofiber necrosis in DMD ...
