However, adult brains do not show higher numbers of apoptotic cells in the cerebellum compared to wild-type. Astrocytes from knockout mice as well as heterozygous mice have a significant impairment in engulfment of apoptotic cells (PubMed:27170117). Reduced proliferation of primary myoblasts (Ref.10). Mutants have normal mobility and their skeletal muscles show mildly increased endomysial connective tissue. They display reduced motor activity after exercise and show slower muscle regeneration (PubMed:28498977). MEGF10 and DMD double knockout animals have pronounced fiber size variability and intracellular inclusions in the quadriceps femoris with extensive endomysial connective tissue infiltration. Mice develop muscle weakness, kyphosis and a waddling gait. At 2 months of age, they have reduced contractile force compared to wild-type mice. They display reduced motor activity after exercise and they walk shorter distances than wild-type. They have a delayed regeneration after muscle injury and an aberrant muscle fber typing and cross-sectional areas (PubMed:28498977). {ECO:0000269|PubMed:27170117, ECO:0000269|PubMed:28498977, ECO:0000269|Ref.10}. |
