1.	Von Walden, Ferdinand, et al. (författare) Muscle contractures in patients with cerebral palsy and acquired brain injury are associated with extracellular matrix expansion, pro-inflammatory gene expression, and reduced rRNA synthesis 2018 Ingår i: Muscle and Nerve. - : Wiley-Blackwell. - 0148-639X .- 1097-4598. ; 58:2, s. 277-285 Tidskriftsartikel (refereegranskat)abstract Introduction: Children with cerebral palsy (CP) and acquired brain injury (ABI) commonly develop muscle contractures with advancing age. An underlying growth defect contributing to skeletal muscle contracture formation in CP/ABI has been suggested.Methods: The biceps muscles of children and adolescents with CP/ABI (n=20) and typically developing controls (n=10) were investigated. We used immunohistochemistry, quantitative real-time polymerase chain reaction, and Western blotting to assess gene expression relevant to growth and size homeostasis.Results: Classical pro-inflammatory cytokines and genes involved in extracellular matrix (ECM) production were elevated in skeletal muscle of children with CP/ABI. Intramuscular collagen content was increased and satellite cell number decreased and this was associated with reduced levels of RNA polymerase I transcription factors, 45s pre-rRNA and 28S rRNA.Discussion: The present study provides novel data suggesting a role for pro-inflammatory cytokines and reduced ribosomal production in the development/maintenance of muscle contractures, possibly underlying stunted growth and perimysial ECM expansion.
