Mapping the non-coding RNA landscape in skeletal muscle health and disease
Project Summary Skeletal muscle tissues are developed and maintained through the coordinated action of myogenic and non- myogenic cells. Dysregulation of myogenic cell identities and functions are commonly observed in skeletal muscle disease. Facioscapulohumeral muscular dystrophy (FSHD) is the second most common inherited muscular dystrophy and results in progressive muscle weakness without any effective therapies. Numerous cellular etiologies are observed in FSHD, such as loss of myogenic cells, including muscle stem cells and myofibers, and increased fibrogenic, adipogenic, and immune cells. The most common form of FSHD arises from aberrant expression of the DUX4 gene caused by…
