Web18 apr. 2024 · We find that impairment of MEF2 also occurs in skeletal muscle of R6/2 mice, a model of Huntington disease where muscle atrophy is prominent. Finally, we demonstrate that SBMA patient muscle biopsies lose expression of MEF2 target genes, and that restoring MEF2 activity rescues mouse muscle fiber size in vivo. WebTertiary, skeletal muscle genes are not all expressed simultaneously. So, temporal specificity and sponsors specificity must be superimposed on the simple style the a transcription factor or its binding sites.
