Tissue specificity of elevated γ-actin in mdx mice and restoration to normal levels by transgene expression. (A) Western blots of DNase I-enriched supernatants from skeletal muscle of control (Con), mdx, and transgenic mdx mice expressing utrophin or dystrophin constructs depicted in Fig. 1 were stained for γ- and α-actin. (B) γ-Actin immunoreactivity in SDS extracts from organs of control and mdx mice. (C) Western blots of DNase I-enriched supernatants of cardiac muscle from control, mdx, and Fiona transgenic mdx mice stained for γ- and α-actin.
