Functional equivalence of dihydropyridine receptor a1S and b1a subunits in triggering excitation-contraction coupling in skeletal muscle
(Sociedad de Biología de Chile, 2004)
Dihydropyridine receptors as voltage sensors for a depolarization-evoked, IP3R-mediated, slow calcium signal in skeletal muscle cells
(Rockefeller University Press, 2003)
The dihydropyridine receptor (DHPR), normally a voltage-dependent calcium channel, functions in skeletal muscle essentially as a voltage sensor, triggering intracellular calcium release for excitation-contraction coupling. ...
Characterization of a multiprotein complex involved in excitation-transcription coupling of skeletal muscle
(2016)
Background: Electrical activity regulates the expression of skeletal muscle genes by a process known as "excitation-transcription" (E-T) coupling. We have demonstrated that release of adenosine 5'-triphosphate (ATP) during ...
Caracterización molecular de un complejo multiproteico involucrado en el acoplamiento excitación-transcripción en el músculo esquelético
(Universidad de Chile, 2014)
La regulación de la expresión génica es un evento crucial para el músculo esquelético, ya
que determina la homeostasis y la plasticidad muscular, permitiendo la remodelación y
transformación del músculo para adaptarse a ...
Slow calcium signals after tetanic electrical stimulation in skeletal myotubes
(Biophysical Society, 2004-05)
The fluorescent calcium signal from rat myotubes in culture was monitored after field-stimulation with tetanic protocols. After the calcium signal sensitive to ryanodine and associated to the excitation-contraction coupling, ...
Characterization of a multiprotein complex involved in excitation-transcription coupling of skeletal muscle
(Biomed Central, 2016)
Background: Electrical activity regulates the expression of skeletal muscle genes by a process known as “
excitation-transcription” (E-T) coupling. We have demonstrated that release of adenosine 5′-triphosphate (ATP) ...
Sodium-dependent action potentials induced by brevetoxin-3 trigger both IP3 increase and intracellular Ca2+ release in rat skeletal myotubes
(CHURCHILL LIVINGSTONE, 2008-09)
Brevetoxin-3 (PbTx-3), described to increase the open probability of voltage-dependent sodium channels, caused trains of action potentials and fast oscillatory changes in fluorescence intensity of fluo-3-loaded rat skeletal ...
