Impact of an electric field on P-type ATPases [PDF]

, 2008
P-type ATPases are membrane proteins acting as ion pumps that drive an active transport of cations across the membrane against a concentration gradient. The required energy for the ion transport is provided by binding and hydrolysis of ATP.

Role of ANO1‐Expressing PDGFRα+ Smooth Muscle Cells in Generating Spontaneous Phasic Contractions of the Rodent Epididymis

Andrology, EarlyView.
ABSTRACT Background Spontaneous phasic contractions (SPCs) in the epididymal duct play an important role in transport and maturation of sperm. In proximal cauda of the rat epididymis, platelet‐derived growth factor receptor α (PDGFRα)‐positive smooth muscle cells (SMCs) generate ANO1 Ca2+‐activated chloride channels (CaCCs)‐dependent spontaneous ...

Actin modifying system of the sarcoplasmic reticulum from rabbit muscle

, 1986
By interaction with sarcoplasmic reticulum from rabbit muscle G-actin loses the capability to polymerize. The modification of actin is due to the concomitant action of the Ca2+ ATPase and of an ADPase embedded in the sarcoplasmic reticulum vesicles ...

Kinetics and mapping of Ca-driven calmodulin conformations on skeletal and cardiac muscle ryanodine receptors

Nature Communications
Calmodulin transduces [Ca2+] information regulating the rhythmic Ca2+ cycling between the sarcoplasmic reticulum and cytoplasm during contraction and relaxation in cardiac and skeletal muscle.

Passive thigh heating improves peak force production in younger adults and early isokinetic force production in younger and older adults

Experimental Physiology, EarlyView.
Abstract Older adults often suffer from reduced physical capability relative to young adults, in part due to impaired muscle function. This study investigated the ergogenic effects of passive thigh heating on knee extensor torque production in healthy older versus younger adults.

Contractile proteins and sarcoplasmic reticulum in physiologic cardiac hypertrophy

, 1981
To study effects of physiologic hypertrophy on contractile protein ATPases and sarcoplasmic reticulum, hypertrophy was caused in female Wistar rats by a chronic swimming program.

Calcium release from aortic sarcoplasmic reticulum

, 1989
The ability of inositol 1,4,5-trisphosphate (IP3) and other inositol phosphates to induce calcium release from canine aortic sarcoplasmic reticulum vesicles was examined. Using the calcium indicator chlorotetracycline or antipyrylazo III, aortic vesicles

Changes in motor unit conduction velocity after unilateral lower‐limb suspension and active recovery are correlated with muscle ion channel gene expression

Experimental Physiology, EarlyView.
Abstract The effects of muscle disuse on the propagation of action potentials along motor unit (MU) muscle fibres, a key process for effective muscle activation and force generation, remain poorly understood. The aim of this study was to investigate changes in action potential propagation and to identify biological factors influencing these changes ...
