A study of the mechanisms of excitation–contraction coupling in frog skeletal muscle based on measurements of [Ca2+] transients inside the sarcoplasmic reticulum
Autor: J. Fernando Olivera, Gonzalo Pizarro
Publikováno v: Journal of Muscle Research and Cell Motility. 39:41-60
[Ca2+] transients inside the sarcoplasmic reticulum (SR) were recorded in frog skeletal muscle twitch fibers under voltage clamp using the low affinity indicator Mag Fluo 4 (loaded in its AM form) with the purpose of studying the effect on Ca2+ relea

Excitation contraction uncoupling by high intracellular [Ca2+] in frog skeletal muscle: a voltage clamp study
Autor: J. Fernando Olivera, Gonzalo Pizarro
Publikováno v: Journal of Muscle Research and Cell Motility. 37:117-130
Raising the intracellular [Ca2+] ([Ca2+]i) was previously found to produce uncoupling between the electrical depolarization of the transverse tubules and contraction in skinned muscle fibers. Here we study the effect of elevated [Ca2+]i in voltage cl

The dynamics of Ca2+ within the sarcoplasmic reticulum of frog skeletal muscle. A simulation study
Autor: Gonzalo Pizarro, J. Fernando Olivera
Publikováno v: Journal of Theoretical Biology. 504:110371
In skeletal muscle, Ca2+ release from the sarcoplasmic reticulum (SR) triggers contraction. In this study we develop a two compartment model to account for the Ca2+ dynamics in frog skeletal muscle fibers. The two compartments in the model correspond

Two inhibitors of store operated Ca2+ entry suppress excitation contraction coupling in frog skeletal muscle
Autor: J Fernando, Olivera, J, Fernando Olivera, Gonzalo, Pizarro
Publikováno v: Journal of Muscle Research and Cell Motility. 31:127-139
Two drugs, 2-APB and SKF-96365, commonly used to block Store Operated Ca(2+) Entry (SOCE) were found to have inhibitory effects at different levels of the Excitation Contraction Coupling (ECC) process in frog skeletal muscle fibers. Treatment with ei

A reappraisal of the Ca2+ dependence of fast inactivation of Ca2+ release in frog skeletal muscle
Autor: Gonzalo Pizarro, J. Fernando Olivera
Publikováno v: Journal of Muscle Research and Cell Motility. 31:81-92
Two procedures to inhibit Ca(2+) release designed to differentiate between local and common pool mechanisms for the Ca(2+) dependent, fast inactivation of Ca(2+) release in skeletal muscle of the frog were compared. Inhibition by voltage dependent in

Altered Na + transport after an intracellular α-subunit deletion reveals strict external sequential release of Na + from the Na/K pump
Autor: Craig Gatto, J. Fernando Olivera, Siddhartha Yaragatupalli, Pablo Artigas
Publikováno v: Proceedings of the National Academy of Sciences. 106:15507-15512
The Na/K pump actively exports 3 Na + in exchange for 2 K + across the plasmalemma of animal cells. As in other P-type ATPases, pump function is more effective when the relative affinity for transported ions is altered as the ion binding sites altern
