The presence of abnormally shaped nuclei in the skeletal muscles of EDMD patients and murine models has been reported both in\u00a0vivo and in\u00a0vitro; however, how the presence of nuclear architectural abnormalities affects disease development and progression remains unclear. In this study, we analyzed slow\u2010twitch soleus (SOL) muscles and fast\u2010twitch extensor digitorum longus (EDL) muscles from the following EDMD model mice: emerin knockout (Emd),\n                    <jats:italic>Lmna<\/jats:italic>\n                    <jats:sup>H222P\/H222P<\/jats:sup>\n                    knockin (H222P), and Emd\/H222P double\u2010mutated (EH), to elucidate the effects of altered nuclear shapes on fiber\u2010type\u2010specific disease development. Dystrophic phenotypes were exclusively detected in the SOL muscles of EH mice, and myonuclear shape irregularities were observed only in the SOL muscle but not in the EDL muscle. Recovery from cardiotoxin (CTX) injection improved the shapes of peripheral myonuclei, and muscle histology and function, concomitant with an increase in the number and size of type 1 fibers in the regenerated SOL muscles of EH mice 42\u2009days after the muscle damage. Importantly, nuclear morphology was relatively retained even after 126\u2009days from the CTX injection, although dystrophic pathology gradually progressed. Taken together, our results indicate that the presence of nuclear morphological changes plays a minor role in the fiber\u2010type\u2010specific progression of muscular dystrophy in EDMD.\n
