High impact information on Muscle Fibers

  • All muscle fibers use Ca(2+) as their main regulatory and signaling molecule [7].
  • When Foxo activation is blocked by a dominant-negative construct in myotubes or by RNAi in mouse muscles in vivo, atrogin-1 induction during starvation and atrophy of myotubes induced by glucocorticoids are prevented [8].
  • Here, we show that in cultured myotubes undergoing atrophy, the activity of the PI3K/AKT pathway decreases, leading to activation of Foxo transcription factors and atrogin-1 induction [8].
  • Moreover, constitutively active Foxo3 acts on the atrogin-1 promoter to cause atrogin-1 transcription and dramatic atrophy of myotubes and muscle fibers [8].
  • These data demonstrate that following myotube formation, myotubes recruit myoblast fusion by secretion of IL-4, leading to muscle growth [9].

Associations of Muscle Fibers with chemical compounds

  • Direct observation of the rapid aggregation of acetylcholine receptors on identified cultured myotubes after exposure to embryonic brain extract [25].
  • We conclude that the 16S enzyme in C2 myotubes occurs in focal patches on the cell surface, where it is associated with the extracellular matrix [26].
  • However, creatine kinase activity rises during myotube formation and then drops abnormally, and myokinase activity fails to increase appreciably [27].
  • RSV transformation, phorbol myristate acetate (PMA) and retinoic acid all induced high levels of plasminogen activator production by differentiating myotubes in the absence of DNA synthesis [28].
  • A glycoprotein purified from chick brain, of relative molecular mass 42,000, increases the rate of appearance of acetylcholine receptors (AChRs) on the surface of chick myotubes [29].
 

Gene context of Muscle Fibers

  • These results indicate that type I myotubes are dependent upon Egr3-mediated transcription for proper spindle development [30].
  • These are two essential functions of muscle fibers, known to be impaired in mdx mouse muscles and Duchenne muscular dystrophy (DMD) patients [31].
  • Thus, although p107 could substitute for Rb as a cofactor for differentiation, it could not maintain the terminally differentiated state in Rb-/- myotubes [18].
  • The Drosophila neuregulin homolog Vein mediates inductive interactions between myotubes and their epidermal attachment cells [32].
  • However, these partially differentiated cells are unable to undergo further differentiation to form muscle fibers in the absence of mef2 [33].
