Deskripsi
PAX7 transcription factor specifies the myogenic identity of muscle stem cells and acts as a nodal factor by stimulating proliferation while inhibiting differentiation. Here authors find that Mll1 deletion in myoblasts in mice results in reduced H3K4me3 at both Pax7 and Myf5 promoters, reduced Pax7 and Myf5 expression, and proliferation defects.
