Abstract:
The effects of iodoacetic acid (IAA) and ischemic contraction were studied in rat extensor digitorum longus muscles. Ischemic contraction of IAA-treated muscles produced contracture. The onset of contracture was not associated with a change in sarcolemmal electrical properties or reduction in intracellular [ATP]; however, [creatine phosphate] was reduced by 75% and free [ADP] was increased by 665%. Continued stimulation of IAA-treated fibers resulted in depolarization, loss of membrane excitability, further depletion of creatine phosphate, and reduction in [ATP]. The effects seen in IAA-treate

Abstract:
Remodeling of skeletal muscle in response to altered patterns of contractile activity is achieved, in part, by the regulated degradation of cellular proteins. The ubiquitin-proteasome system is a dominant pathway for protein degradation in eukaryotic cells. To test the role of this pathway in contraction-induced remodeling of skeletal muscle, we used a well-established model of continuous motor nerve stimulation to activate tibialis anterior (TA) muscles of New Zealand White rabbits for periods up to 28 days. Western blot analysis revealed marked and coordinated increases in protein levels of

Abstract:
The active isometric force developed by a muscle decreases at muscle lengths below an optimal length (Lo). However, when the length of an actively contracting muscle is abruptly decreased, a lower level of isometric force is reached during force redevelopment than when the contraction is initiated at the shorter length. This has been attributed to a deactivation of contractile proteins caused by shortening. In this study, intracellular Ca2+ and myosin light chain (MLC) phosphorylation were measured to assess the mechanisms for the modulation of isometric force caused by changing smooth muscle

Blebbistatin is a powerful inhibitor of actin-myosin interaction in isolated contractile proteins. To examine whether blebbistatin acts in a similar manner in the organized contractile system of striated muscle, the effects of blebbistatin on contraction of cardiac tissue from mouse were studied. The contraction of paced intact papillary muscle preparations and shortening of isolated cardiomyocytes were inhibited by blebbistatin with inhibitory constants in the micromolar range (1.3–2.8 μM). The inhibition constants are similar to those previously reported for isolated cardiac myosin subfragme

Abstract:
The cytoplasm of eukaryotic cells contains several membrane-delimited compartments of specific molecular compositions and functions. Among those, the vacuole of fungal cells is often described as an organelle equivalent to the lysosomes of animal cells and the vacuoles of plant cells. These compartments indeed share two similar features: they contain a wide variety of hydrolases and are the most acidic compartments of the cell, which accounts for their key role in the intracellular degradation of macromolecules. In humans, dysfunctions of the lysosomes often give rise to lysosomal related dise

ATP released from parasympathetic nerves can mediated bladder contraction, can activate purinergic P2Y/Gq/11-coupled G protein-coupled receptors (GPCR) expressed on detrusor (bladder) smooth muscle cells (DSMC). P2Y/Gq/11 signalling activates phospholipase C (PLC) and increases intracellular calcium concentrations to induce contraction. DSMC contractile GPCR activity is tightly regulated to prevent inappropriate contraction/incontinence. Additionally, GPCRs activity is regulated by G protein-coupled receptor kinase (GRK) and arrestin proteins, it is likely that they play a similar role in DSMC

Abstract:
Epithelial tissues undergo extensive remodeling during embryonic development. Recent studies have revealed that, in a number of developmental processes, epithelial remodeling is associated with pulsations of individual cell surface areas and cortical actomyosin flows. During Drosophila dorsal closure, the amnioserosa (AS), a contractile tissue covering the dorsal region of the embryo, shows contractile pulsations and regular actomyosin flows during the reduction of its apical surface area. The biophysical mechanism driving these shape pulsations as well as the role of contractile actomyosin w
