The MyоD trаnscriptiоn fаctоr is normаlly found in differentiating muscle cells and participates in the transcription of genes that produce muscle-specific proteins. Amazingly, expression of MyoD in fibroblasts causes these cells derived from skin connective tissue to produce proteins normally only seen in muscles. However, some other cell types do not transcribe muscle-specific genes when MyoD is expressed in them. What’s the best explanation of why MyoD can cause fibroblasts to express muscle-specific genes?
