mu-Calpain and calpain-3 are Ca2+-dependent proteases found in skeletal muscle. Autolysis of calpains is observed using Western blot analysis as the cleaving of the full-length proteins to shorter products. Biochemical assays suggest that mu-calpain becomes proteolytically active in the presence

In skeletal muscle fibers, the coupling between excitation of the surface membrane and the release of Ca(2+) from the sarcoplasmic reticulum is irreversibly disrupted if cytoplasmic Ca(2+) concentration ([Ca(2+)]) is raised to micromolar levels for a prolonged period. This excitation-contraction
Eccentric (ECC) contraction-induced muscle damage is associated with calcium ion (Ca2+) influx from the extracellular milieu through stretch-activated channels. It remains unknown whether Ca2+ influx consequent to repetitive ECC contractions is nonuniform across different muscle regions. We tested the hypothesis

Skeletal muscle undergoes significant atrophy in Type 2 diabetic patients and animal models. We aimed to determine if atrophy of Zucker rat skeletal muscle was due to the activation of intracellular damage pathways induced by excess reactive oxygen species production
It has been shown that calpains are involved in the proteolysis of muscle proteins that occurs with eccentric contraction (ECC) and that exogenously applied nitric oxide decreases the calpain-mediated proteolysis. The aim of this study was to examine the effects
