(A) Quantification of UNC45B expression in gastrocnemius muscle, soleus muscle, plantaris muscle, diaphragm, and heart in Unc45b flox/flox mice and ACTA1‐MerCreMer; Unc45b flox/flox mouse 8 weeks after tamoxifen injection. (B) Representative western blots for UNC45B. (C) UNC45B expression. (D) Body weight. Relative mass of the (E) gastrocnemius and (F) soleus muscles, expressed as a ratio to body weight. (G) Grip strength normalized to body weight. (H) Plantar flexor torque. (I) Plantar flexor torque normalized to triceps surae muscle mass. (J) Representative images of gastrocnemius muscle. Scale bar set to 50 μm. CSA of (K) type I, (L) type IIa, (M) type IIx, and (N) type IIb fibers in gastrocnemius muscle. (O) Representative images of soleus muscle. Scale bar set to 50 μm. CSA of (P) type I, (Q) type IIa, (R) type IIx, and (S) type IIb fibers in soleus muscle. (T) Representative western blots. (U) Myosin expression. Data are shown as means and individual values ± standard error (2 weeks, n = 6; 4 weeks, n = 6; 8 weeks, n = 6). Different letters indicate significant differences between groups. BW, body weight; fCSA, fiber cross‐sectional area; GAS, gastrocnemius; SOL, soleus; Unc45b imKO, inducible skeletal muscle‐specific Unc45b knockout.
