(A) Lysates from TAΔDHPR (ΔDHPR) and TACtrl (c) were immuno‐blotted for RyR1 or α‐actin. (n=4). Graph depicts mean±s.e.m. of relative expression of RyR1 determined by densitometry and nomalized to the α‐actin expression for each muscle. Results were expressed in protein levels of ΔDHPR in TAΔDHPR normalized to TACtrl for each mice, *P⩽0.005, n=4.
