The T‐tubule membrane ATP‐operated P2X4 receptor influences contractility of skeletal muscle
TLDR
Data reveal that ATP‐mediated Ca2+ entry, most likely through P2X4 receptor, may play an important role in modulating the contractility of skeletal muscle. Expand
Denervation in murine fast-twitch muscle: short-term physiological changes and temporal expression profiling.
TLDR
It is concluded that, if studied at the mRNA level, fast muscles appear not less responsive than slow muscles to the interruption of neural stimulation. Expand
Sphingosine 1-phosphate signaling is involved in skeletal muscle regeneration.
TLDR
The present results show that S1P signaling participates in the regenerative processes of skeletal muscle. Expand
Myosin heavy chain composition of single fibres from normal human muscle.
TLDR
Analysis of MHC of single human muscle fibres shows that human muscles contain a large population of fibres showing the coexistence of type 2A and 2B MHC. Expand
Adaptation of Mouse Skeletal Muscle to Long-Term Microgravity in the MDS Mission
TLDR
The study shows the extended sensitivity of antigravity soleus muscle after prolonged exposition to microgravity, suggests possible mechanisms accounting for the resistance of EDL, and individuates some molecular targets for the development of countermeasures. Expand
High-frequency fatigue of skeletal muscle: role of extracellular Ca2+
TLDR
Results indicate that a transmembrane Ca2+ influx, mainly through NCX, may play a protective role during HFF development in soleus muscle. Expand
Effects of age on sarcoplasmic reticulum properties and histochemical composition of fast- and slow-twitch rat muscles.
TLDR
The present results suggest that the changes in contractile properties of aged muscles may be related to the changes not only in fibre composition but also in the mechanism of calcium release from sarcoplasmic reticulum. Expand
Trophic action of sphingosine 1-phosphate in denervated rat soleus muscle.
TLDR
It is suggested that S1P acts as a trophic factor of skeletal muscle as well as its precursor, sphingosine (Sph), which attenuated the progress of denervation-induced muscle atrophy. Expand
Chronic denervation of rat diaphragm: Selective maintenance of adult fast myosin heavy chains
TLDR
The selective maintenance after long‐term denervation of fast myosin in adult muscle provides good evidence of the independence of the genetic expression of myOSin from a direct neural chemotrophic control. Expand
Effects of fatigue on sarcoplasmic reticulum and myofibrillar properties of rat single muscle fibers.
TLDR
It is indicated that persistent modifications of myofibrillar and SR properties contribute to fatigue-induced muscle force decline only in slow fibers, and these alterations may be either enhanced or counteracted, in vivo, by the metabolic changes that normally occur during fatigue development.
