Distribution of myosin heavy chain isoforms in non-weight-bearing rat soleus muscle fibers. J. Appl.
Physiol. 81(6): 2540-2546, 1996.
The effects of
14 days of spaceflight (SF) or hindlimb suspension (HS) (Cosmos 2044)
on myosin heavy chain (MHC) isoform content of the rat soleus muscle
and single muscle fibers were determined. On the basis of
electrophoretic analyses, there was a de novo synthesis of type IIx MHC
but no change in either type I or IIa MHC isoform proportions after
either SF or HS compared with controls. The percentage of fibers
containing only type I MHC decreased by 26 and 23%, and the percentage
of fibers with multiple MHCs increased from 6% in controls to 32% in
HS and 34% in SF rats. Type IIx MHC was always found in combination
with another MHC or combination of MHCs; i.e., no fibers contained type
IIx MHC exclusively. These data suggest that the expression of the
normal complement of MHC isoforms in the adult rat soleus muscle is
dependent, in part, on normal weight bearing and that the absence of
weight bearing induces a shift toward type IIx MHC protein expression in the preexisting type I and IIa fibers of the soleus.
