PAX7
Description
PAX7, a member of the paired box (PAX) family of transcription factors, plays a pivotal role in muscle development and regeneration. It acts as a master regulator, controlling the proliferation and differentiation of satellite cells, the resident stem cells responsible for muscle repair. PAX7 expression is tightly regulated during development, ensuring proper muscle formation. In adulthood, PAX7 remains active in satellite cells, enabling them to respond to injury and regenerate damaged muscle fibers. The gene‘s critical role in muscle homeostasis makes it a potential therapeutic target for various muscular disorders.
Associated Diseases
- Muscular Dystrophies (e.g., Duchenne Muscular Dystrophy, Becker Muscular Dystrophy)
- Myopathies (e.g., Myotonic Dystrophy, Limb-Girdle Muscular Dystrophy)
- Rhabdomyosarcoma (a type of childhood cancer)
- Congenital Myopathies
Did you know?
PAX7 is also expressed in other tissues, including the brain and pancreas, suggesting it may have broader roles beyond muscle.
