MDFI (MyoD Family Inhibitor): MDFI is a gene that plays a role in regulating muscle differentiation and development. It acts as an inhibitor of MyoD family transcription factors, which are crucial regulators of myogenesis. By modulating their activity, MDFI helps control the proliferation and differentiation of muscle cells, playing an essential role in muscle formation and repair. Dysregulation of MDFI can affect muscle development and regeneration.
