E2F1 and Miyoshi myopathy: As a critical transcription factor, STAT3 modulates a broad panel of important genes transcription and expression, such as Bcl-2, Mcl-1, survivin and XIAP (that are apoptosis related genes), cyclin-dependent kinase, transcription factor E2F-1 (that are cell cycle related regulators) and D-type cyclins (that are universally dysregulated in MM cells) [8, 27–30].
