We investigated the regulatory effects of neural activation and trophic factors on the selective accumulation of succinate dehydrogenase (SDH; EC 1.3.99.1) activity at the endplate, as well as within subsarcolemmal and intermyofibrillar regions of ra

Although the function of posttranscriptional processes in regulating the expression of genes involved in muscle fiber formation (myogenesis) is well accepted, the mechanisms by which these effects are mediated remain elusive. Here, we uncover such a

Duchenne muscular dystrophy (DMD) is caused by the absence of full-length dystrophin molecules in skeletal muscle fibers. In normal muscle, dystrophin is found along the length of the sarcolemma where it links the intracellular actin cytoskeleton to

Several regulatory mechanisms contribute to the accumulation and maintenance of high concentrations of acetylcholine receptors (AChR) at the postsynaptic membrane of the neuromuscular junction, including compartmentalized gene transcription, targetin

The dihydropyridine (DHP) and ryanodine (RY) receptors play a critical role in depolarization-induced calcium release in skeletal muscle, yet the factors which govern their expression remain unknown. We investigated the roles of electrical activity a

Our aim was to quantify the overload-induced hypertrophy and conversion of fiber types (type II to I) occurring in the medial head of the gastrocnemius muscle (MG). Overload of MG was induced by a bilateral tenotomy/retraction of synergists, followed

We have investigated the impact of compensatory overload on the content of acetylcholinesterase (AChe) molecular forms in the rat fast-twitch medial gastrocnemius (MG). Overload was induced by way of a bilateral tenotomy of the MG's functional synerg

The purpose of this study was to evaluate the specificity of the hexagonal obstacle test (HEX) as a measure of anaerobic endurance for Alpine skiers. Subjects were varsity Alpine skiers (AS, n = 10), varsity athletes (VA, n = 10) and physical educati

The purpose of the study was to examine the patterns of electromyographic (EMG) activity of the rat plantaris during loaded swimming in comparison with other locomotor activities. Five female Sprague-Dawley rats were implanted with chronic bipolar el

The effects of increases in neuronal activity on fast axonal transport of acetylcholinesterase (AChE) in sciatic motoneurons were studied by subjecting rats to daily running or swimming training (8 weeks). Net accumulation of AChE activity proximal a
