(C) Six months post injection, lysates from TAΔDHPR (ΔDHPR) and TACtrl (c) were immuno‐blotted for α1S or α-actin for four mice. Graph depicts mean±s.e.m. of relative expression of α1S subunit determined by densitrometry and nomalized to the α-actin expression for each muscle. Results were expressed in protein levels of α1S subunit in TAΔDHPR normalized to TACtrl for each mice, **P⩽0.001, n=4.
