AKT1 and myopathy: Notably, immunohistochemical analysis of M‐AKTFOXO1TKO and M‐AKTTSCTKO EDL and soleus muscles displayed mild myopathy and fibre composition similar to M‐AKTDKO muscles, indicating that these individual pathways alone are not sufficient to drive the muscle structural properties in the absence of AKT (FigureS4A–S4C).
