by Win Reynolds, Northwestern University Model for BCL6-mediated control of skeletal muscle proteostasis. BCL6-mediated transcriptional regulation controls the expression of atrogenic regulators to establish and maintain skeletal muscle mass. BCL6 directly represses Eif4ebp1 and possibly Mstn, while it directly activates Igf1 and Ar. Loss of Bcl6 in muscle acutely reduces cap-dependent translation and anabolic signaling, resulting...
