The role of Na+/K+-ATPase during chick skeletal myogenesis. [PDF]

open access: yesPLoS ONE, 2015
The formation of a vertebrate skeletal muscle fiber involves a series of sequential and interdependent events that occurs during embryogenesis. One of these events is myoblast fusion which has been widely studied, yet not completely understood.

Effects of Insulin-Like Growth Factor-I on the Expression of Atrogin-1/MAFbx in Chick Myotube Cultures

open access: yesThe Journal of Poultry Science, 2017
The expression of atrogin-1/MAFbx, a muscle-specific E3 ubiquitin ligase, is increased in catabolic conditions that result in muscle atrophy. The expression of atrogin-1/MAFbx mRNA is also decreased by the insulin-like growth factor-I (IGF-I) in ...

Agrin isoforms and their role in synaptogenesis [PDF]

open access: yes, 1992
Agrin is thought to mediate the motor neuron-induced aggregation of synaptic proteins on the surface of muscle fibers at neuromuscular junctions. Recent experiments provide direct evidence in support of this hypothesis, reveal the nature of agrin ...

Myofibrillar Proteolysis in Chick Myotubes during Oxidative Stress

open access: yesJournal of Nutritional Science and Vitaminology, 2004
Changes in protein conformation and proteolysis in chick myotubes in response to the induction of oxidative stress by H2O2 treatment were studied. Myotubes were treated for 1 h with H2O2. After this treatment, the H2O2 was removed and the cells were cultured in serum-free medium for 6 and 24 h.

Permeability properties of chick myotube acetylcholine-activated channels

open access: yesBiophysical Journal, 1984
The acetylcholine-(ACh-)activated channels of chick myotubes were studied by the patch-clamp method. Single-channel amplitudes were measured over a wide range of potentials in solutions of cesium, arginine, and three small amines. Symmetrical, isotonic cesium solutions gave a linear I-V relationship with the single-channel conductance, gamma, of 42 pS ...

Accumulation of muscle ankyrin repeat protein transcript reveals local activation of primary myotube endcompartments during muscle morphogenesis [PDF]

open access: yes, 1997
The characteristic shapes and positions of each individual body muscle are established during the process of muscle morphogenesis in response to patterning information from the surrounding mesenchyme. Throughout muscle morphogenesis, primary myotubes are

Differences in the expression and distribution of flotillin-2 in chick, mice and human muscle cells.

open access: yesPLoS ONE, 2014
Myoblasts undergo a series of changes in the composition and dynamics of their plasma membranes during the initial steps of skeletal muscle differentiation.

Posttranslational control of membrane-skeleton (ankyrin and alpha beta- spectrin) assembly in early myogenesis [PDF]

open access: yes, 1985
Adult chicken skeletal muscle cells express polypeptides that are antigenically related to alpha-spectrin (Mr 240,000) and beta-spectrin (Mr 220,000-225,000), the major components of the erythrocyte membrane- skeleton, and to ankyrin (Mr 237,000; also ...

Biphasic effect of pentobarbitone on chick myotube nicotinic receptor channel kinetics [PDF]

open access: yesBritish Journal of Pharmacology, 1996
The modulatory action of pentobarbitone on chick myotube nicotinic acetylcholine receptor kinetics was studied by the patch clamp technique, particularly focussing on effects at low concentrations. Open time sojourn distributions of foetal‐type receptors recorded at room temperature (22–24°C) in cell‐attached mode in the presence of 0.2 μm ...

Distinct molecular interactions mediate neuronal process outgrowth on non-neuronal cell surfaces and extracellular matrices. [PDF]

open access: yes, 1986
We have compared neurite outgrowth on extracellular matrix (ECM) constituents to outgrowth on glial and muscle cell surfaces. Embryonic chick ciliary ganglion (CG) neurons regenerate neurites rapidly on surfaces coated with laminin (LN), fibronectin (FN),
