Inhibition of mechanosensitive cation channels inhibits myogenic differentiation by suppressing the expression of myogenic regulatory factors and caspase-3 activity.
Mechanosensitive cation channels (MSC) are ubiquitous in eukaryotic cell types. However, the physiological functions of MSC in several tissues remain in question. In this study we have investigated the role of MSC in skeletal myogenesis. Treatment of C2C12 myoblasts with gadolinium ions (MSC blocker) inhibited myotube formation and the myogenic index in differentiation medium (DM). The enzymati...
متن کاملFunctional conservation of nematode and vertebrate myogenic regulatory factors.
The Caenorhabditis elegans protein, CeMyoD, is related to the vertebrate myogenic regulatory factors MyoD, myogenin, MRF-4 and Myf-5. Like its vertebrate counterparts, CeMyoD accumulates in the nucleus of striated muscle cells prior to the onset of terminal differentiation. CeMyoD also shares functional similarities with the vertebrate myogenic regulatory factors. Viral LTR driven expression of...
متن کاملExpression of myogenic regulatory factors and myo-endothelial remodeling in sporadic inclusion body myositis
Muscle repair relies on coordinated activation and differentiation of satellite cells, a process that is unable to counterbalance progressive degeneration in sporadic inclusion body myositis (s-IBM). To explore features of myo regeneration, the expression of myogenic regulatory factors Pax7, MyoD and Myogenin and markers of regenerating fibers was analyzed by immunohistochemistry in s-IBM muscl...
متن کاملExpression of myogenic regulatory factors in chicken embryos during somite and limb development
The expression of the myogenic regulatory factors (MRFs), Myf5, MyoD, myogenin (Mgn) and MRF4 have been analysed during the development of chicken embryo somites and limbs. In somites, Myf5 is expressed first in somites and paraxial mesoderm at HH stage 9 followed by MyoD at HH stage 12, and Mgn and MRF4 at HH stage 14. In older somites, Myf5 and MyoD are also expressed in the ventrally extendi...
متن کاملInfluence of growth factors on poultry myogenic satellite cells.
Skeletal muscle development in avian and mammalian embryos depends on the proliferation, differentiation, and fusion of embryonic myoblasts. During the late fetal period and following birth or hatching, myogenic satellite cells are responsible for this developmental function. Satellite cells, which are found adjacent to existing skeletal muscle fibers fuse with these fibers and their nuclei dir...
