to examine the possible role of dna methylation in the modulation of expression of genes involved in the differentiation of muscle cells , we compared the methylation state of a number of cpg sites in the rat skeletal muscle actin and myosin light chain 2 genes , in muscle and nonmuscle cells , and in proliferating myoblasts and differentiated myotubes of the myogenic cell line l8 .
