... in somatic cells is transcribed in oocytes. We find that M1 oocytes have an extremely strong transcription-inducing activity. They cause muscle genes of nuclei from non-muscle somatic cells, after injection into oocytes, to be transcribed to nearly the same extent as muscle genes in muscle cells. We show...

...Shu-Chun Lin; Meei-Hua Lin; Péter Horváth; Karen L. Reddy; Robert V. Storti ABSTRACT In vertebrates, transcriptional control of skeletal muscle genes during differentiation is regulated by enhancers that direct the combinatorial binding and/or interaction of MEF2 and the bHLH MyoD family...
