Defects in Ca2+ release associated with local expression of pathological ryanodine receptors in mouse muscle fibresRomain Lefebvre
CNRS UMR 5534, Universite Lyon 1, Centre de Génétique et de Physiologie Moléculaire et Cellulaire, Villeurbanne, France
J Physiol 589:5361-82. 2011..Furthermore, the results indicate that RyR1 channel density is tightly regulated even under the present conditions of forced exogenous expression...
Spontaneous and voltage-activated Ca2+ release in adult mouse skeletal muscle fibres expressing the type 3 ryanodine receptorClaude Legrand
Physiologie Intégrative Cellulaire et Moléculaire, Universite Lyon 1, UMR CNRS 5123, Villeurbanne, France
J Physiol 586:441-57. 2008..Conversely we find no evidence that it could contribute to the production of discrete voltage-activated Ca2+ release events in differentiated mammalian skeletal muscle...
Transient loss of voltage control of Ca2+ release in the presence of maurocalcine in skeletal muscleSandrine Pouvreau
, , UMR CNRS 5123, , 43 Boulevard du 11 Novembre 1918, F 69622 Villeurbanne Cedex, France
Biophys J 91:2206-15. 2006..Results suggest that MCa binds to RYr that open on membrane depolarization and that this interaction specifically alters the process of repolarization-induced closure of the channels...
In vivo expression of G-protein beta1gamma2 dimer in adult mouse skeletal muscle alters L-type calcium current and excitation-contraction couplingNorbert Weiss
Universite Lyon 1, UMR CNRS 5123, Physiologie Intégrative Cellulaire et Moléculaire, Bâtiment R Dubois, 43 Boulevard du 11 Novembre 1918, Villeurbanne, France
J Physiol 588:2945-60. 2010..Our data suggest that the G-protein beta(1)gamma(2) dimer may play an important regulatory role in skeletal muscle excitation-contraction coupling...
Calcium signaling in isolated skeletal muscle fibers investigated under "Silicone Voltage-Clamp" conditionsClaude Collet
, , UMR CNRS 5123, F69622 Villeurbanne, France
Cell Biochem Biophys 40:225-36. 2004..Focus is given to the potency of this approach to investigate both fundamental aspects of excitation-contraction coupling and potential alterations of intracellular calcium handling in some muscle diseases...
Control of intracellular calcium in the presence of nitric oxide donors in isolated skeletal muscle fibres from mouseSandrine Pouvreau
, , UMR CNRS 5123, , 43 Boulevard du 11 Novembre 1918, F 69622 Villeurbanne Cedex, France
J Physiol 560:779-94. 2004..This SR Ca(2+) leak and the resulting increase in resting [Ca(2+)] may be important in mediating the effects of excess NO on voltage-activated calcium release...
Altered myoplasmic Ca(2+) handling in rat fast-twitch skeletal muscle fibres during disuse atrophyNorbert Weiss
Physiologie Intégrative Cellulaire et Moléculaire, Universite Lyon 1, UMR CNRS 5123, Bât Raphaël Dubois, 43 Boulevard du 11 Novembre 1918, 69622, Villeurbanne, France
Pflugers Arch 459:631-44. 2010..Overall results provide the first functional evidence for severely altered intracellular Ca(2+) removal capabilities in atrophied fast-type muscle fibres and highlight the possible contribution of reduced mitochondrial polarisation...
The L-type voltage-dependent Ca2+ channel EGL-19 controls body wall muscle function in Caenorhabditis elegansMaelle Jospin

Sustained release of calcium elicited by membrane depolarization in ryanodine-injected mouse skeletal muscle fibersClaude Collet
, , F69622 Villeurbanne, France
Biophys J 82:1509-23. 2002..Within the voltage-sensitive range of calcium release, increasing either the amplitude or the duration of the depolarization seems to enhance the fraction of release channels accessible to ryanodine...
