Effects of fatty acid intermediates on Na+-K+-ATPase activity of cardiac sarcolemma [PDF]

, 1982
The effect of amphiphilic lipid intermediates on the Na+-stimulatable activity of the Na+-K+-ATPase of sarcolemma from adult canine cardiac myocytes was studied. Sarcolemma (mean Na+-stimulatable ATPase activity of 73 mumol.mg sarcolemmal protein-1.h-1)

Excitation-contraction coupling and mechano-sensitivity in denervated skeletal muscles

European Journal of Translational Myology, 2010
Skeletal muscle atrophy can be defined as a wasting or decrease in muscle mass and muscle force generation owing lack of use, ageing, injury or disease. Thus, the etiology of atrophy can be different.

Mechanisms underlying local Ca2+ signalling differences between right and left atrial myocytes at normal and increased frequencies

The Journal of Physiology, EarlyView.
Abstract figure legend Left atrial myocytes have TAT‐associated faster Ca2+ release but are more prone to maladaptation at higher frequencies due to weaker peripheral SR Ca2+ uptake and smaller trigger Ca2+ current. Abstract Changes in heart rate affect Ca2+ signalling and contractility in ventricular muscle, but the effects on atrial Ca2+ signalling ...

Proteomic analysis of the sarcolemma-enriched fraction from dystrophic mdx-4cv skeletal muscle [PDF]

, 2018
The highly progressive neuromuscular disorder dystrophinopathy is triggered by primary abnormalities in the Dmd gene, which causes cytoskeletal instability and loss of sarcolemmal integrity.

Calcium Binding by Skeletal Muscle Sarcolemma

Journal of Biological Chemistry, 1973
Abstract Plasma membranes isolated from rabbit muscle possessed the ability to bind and accumulate calcium ions; these processes required ATP and Mg2+. Binding of Ca2+ was rapid, reaching a maximum within 30 s and was greatly increased in the presence of oxalate or phosphate.

Utility of local capillary supply indices: Insights from computational image‐based modelling

The Journal of Physiology, EarlyView.
Abstract figure legend Local capillary distribution and fibre geometry influence oxygen availability in skeletal muscle. Image‐based modelling of tissue PO2${{P}_{{{{\mathrm{O}}}_2}}}$ shows that area‐based measures of capillary supply – the local capillary density (LCDi) and local maximum diffusion distance (Dmax,i) – most accurately represent the ...

Dystrobrevin deficiency at the sarcolemma of patients with muscular dystrophy. [PDF]

, 1997
Mutations in the genes encoding dystrophin or dystrophin-associated proteins are responsible for Duchenne muscular dystrophy or various forms of limb-girdle muscular dystrophies respectively.

Dystrophin R16/17-syntrophin PDZ fusion protein restores sarcolemmal nNOSμ

Skeletal Muscle, 2018
Background Loss of sarcolemmal nNOSμ is a common manifestation in a wide variety of muscle diseases and contributes to the dysregulation of multiple muscle activities.

14‐3‐3 proteins: Regulators of cardiac excitation–contraction coupling and stress responses

The Journal of Physiology, EarlyView.
Abstract figure legend 14‐3‐3 protein interactions in cardiac regulation. Schematic representation of 14‐3‐3 binding partners in excitation–contraction coupling, transcriptional regulation/development and stress response pathways. Asterisks indicate targets where the exact 14‐3‐3 binding site is unknown.
