High impact information on Myh13

  • VIVIT was found to block the expression of slow myosin heavy chain (MyHC-slow) induced by slow motor neuron activity in regenerating slow soleus muscle and to inhibit the expression of MyHC-slow transcripts and the activity of a MyHC-slow promoter in adult soleus [1].
  • RNase protection assays for the embryonic (Myh3) and extraocular (Myh13) MyHC isoform mRNAs were also performed [2].
  • The contralateral muscles were used to count muscle spindles and spindle fibers (ATPase staining) and to identify MyHC isoforms by immunostaining [3].
  • Importantly, this combined neurotrophin regimen also prevented the disappearance of muscle fibers that express myosin heavy chain IIB (MyHC IIB) in both EDL and TA muscles 3 mo after neonatal sciatic nerve crush [4].
  • We examined the functional role of distinct muscle-CAT (MCAT) elements during non-weight-bearing (NWB) regulation of a wild-type 293-base pair beta-myosin heavy chain (beta MyHC) transgene [5].
 

Anatomical context of Myh13

  • All single soleus muscle fibres from hyperthyroid rats co-expressed types I and IIA myosin heavy chains (type I/IIA fibres) or type I, IIA and IIX myosin heavy chains (type I/IIAX fibres), while only type I MyHC fibres were isolated from the controls [6].
