CASZ1 induces skeletal muscle and rhabdomyosarcoma differentiation through a feed-forward loop with MYOD and MYOG

Embryonal rhabdomyosarcoma (ERMS) is a childhood cancer with impaired myogenic differentiation despite the presence of myogenic transcription factors. Here, the authors show that CASZ1 directly regulates these myogenic factors and the loss of CASZ1 is due to RAS-MEK signaling in ERMS.
