The delivery of adult skeletal muscle stem cells, called satellite cells, to several injured muscles via the circulation would be useful, however, an improved understanding of cell fate and biodistribution following their delivery is import...
The mechanical activation of mTOR signaling: an emerging role for late endosome/lysosomal targeting [0.03%]
mTOR信号的机械激活：晚期内体/溶酶体靶向的作用机制不容小觑

It is well recognized that mechanical signals play a critical role in the regulation of skeletal muscle mass, and the maintenance of muscle mass is essential for mobility, disease prevention and quality of life. Furthermore, over the last 1...
A re-interpretation of the rate of tension redevelopment (k(TR)) in active muscle [0.03%]
肌活组织中张力再发育速度(kTR)的释义研究

A slackening to zero tension by large length release (~20%) and a restretch of active muscle fibres cause a fall and a redevelopment in tension. According to the model of Brenner (Proc Natl Acad Sci USA 85(9):3265-3269, 1988), the rate cons...
Myosin phosphorylation and force potentiation in skeletal muscle: evidence from animal models [0.03%]
骨骼肌肌球蛋白磷酸化与力增强：动物模型证据

Rene Vandenboom et al.
The contractile performance of mammalian fast twitch skeletal muscle is history dependent. The effect of previous or ongoing contractile activity to potentiate force, i.e. increase isometric twitch force, is a fundamental property of fast s...
In vitro myoblast motility models: investigating migration dynamics for the study of skeletal muscle repair [0.03%]
体外肌细胞运动模型：用于探究骨骼肌修复中迁移动力学的研究

K P Goetsch
Skeletal muscle repair requires the migration of myoblasts (activated satellite cells) both to the injury site and then within the wound to facilitate cellular alignment in preparation for differentiation, fusion and eventual healing. Along...
Quantifying SOCE fluorescence measurements in mammalian muscle fibres. The effects of ryanodine and osmotic shocks [0.03%]
肌浆网释放引起的SOCE的荧光定量。ryanodine和高渗休克的影响

Heart disease is a leading cause of death in patients with Duchenne muscular dystrophy (DMD). Patients with DMD lack the protein dystrophin, which is widely expressed in striated muscle. In skeletal muscle, the loss of dystrophin results in...

The trimeric protein AMP-activated protein kinase (AMPK) is an important sensor of energetic status and cellular stress, and mutations in genes encoding two of the regulatory γ subunits cause inherited disorders of either cardiac or skelet...
Influence of chronic food deprivation on structure-function relationship of juvenile rat fast muscles [0.03%]

In the present study, we analyze the influence of chronic undernutrition on protein expression, muscle fiber type composition, and fatigue resistance of the fast extensor digitorum longus (EDL) muscle of male juvenile rats (45 ± 3 days of ...
