RyR2-Mediated Ca2+ Release and Mitochondrial ROS Generation Partake in the Synaptic Dysfunction Caused by Amyloid beta Peptide Oligomers
(2017)
Amyloid beta peptide oligomers (A beta Os), toxic aggregates with pivotal roles in Alzheimer's disease, trigger persistent and low magnitude Ca2+ signals in neurons. We reported previously that these Ca2+ signals, which ...
Estudio de la acumulación activa de calcio en el aparato de golgi de la célula vegetal.
(Universidad de Concepción.Facultad de Ciencias Naturales y OceanográficasDepartamento de Botánica., 2004)
El Ca2+ juega un papel crucial en la fisiología vegetal, actuando como segundo mensajero en la percepción de una gran variedad de señales endógenas y ambientales. El aumento transiente de Ca2+ citosólico en respuesta a ...

Sarcoplasmic reticulum release channels from frog skeletal muscle display two types of calcium dependence
(1993)
Calcium channels derived from sarcoplasmic reticulum of frog skeletal muscle were fused with planar lipid bilayers. Fractional open times displayed two types of calcium dependence: (i) blockable channels showed a bell-shaped ...
The role of CaMKII regulation of phospholamban activity in heart disease
(Frontiers, 2014-01-27)
Phospholamban (PLN) is a phosphoprotein in cardiac sarcoplasmic reticulum (SR) that is a reversible regulator of the Ca2+-ATPase (SERCA2a) activity and cardiac contractility. Dephosphorylated PLN inhibits SERCA2a and PLN ...
Calcium dependence of ryanodine-sensitive calcium channels from brain cortex endoplasmic reticulum
(Elsevier B.V., 1996)
Endoplasmic reticulum vesicles isolated from rat brain cortex and fused with lipid bilayers displayed ryanodine-sensitive calcium channels, with three cytoplasmic calcium dependences. A: Channels (n = 5) stimulated by Ca2+ ...
