Etiology of musculoskeletal maladies in NF1
Project Summary/Abstract Children with Neurofibromatosis Type 1 (NF1) are predisposed to cancer but can also present with unilateral bowing of the tibia that often progresses to fracture. Unlike the robust bone healing of most children, bone healing in these patients fails, leading to invasive and repeated surgeries, and often amputation of the leg. Research focused on identifying the cause of this refractory bone healing revealed that Nf1 deficiency in bone mesenchymal progenitors blunts their osteogenic potential and triggers chronic and uncontrolled RAS/ERK signaling, although blocking this pathway failed to rescue osteoprogenitor differentiation and the delayed bone healing of mice…
