The experiments described in this study support this hypothesis, as alterations in myogenic precursor cell proliferation presumably caused by 18 Gy irradiation resulted in altered levels of specific subpopulations of myogenic precursor cells and the appearance of a dystrophic phenotype in the EOM of the het (mdx:utrophin+/−) model of muscular dystrophy [33], [65]. This evidence concerns the gene UTRN and muscular dystrophy.
