Myosin heavy chain (MHC) isoform composition does not change in the early phases of HU

MHC isoform	C	HU-3	HU-7
MHC-I	28.27 ± 6.31	40.06 ± 13.34	32.29 ± 12.5
MHC-IIA	50.82 ± 7.12	46.75 ± 13.42	36.72 ± 14.47
MHC-IIX	7.78 ± 3.49	9.17 ± 7.25	17.82 ± 9.65
MHC-IIB	13.13 ± 7.67	4.02 ± 2.23	13.17 ± 11.12

MHC isoform composition of soleus muscle of control mice (C), following 3 days (HU-3) and 7 days (HU-7) of HU. MHC composition was determined by SDS-PAGE and densitometric analysis of MHC bands. Data are expressed as mean ± SD.
