  • Title: Interleukin-1 Beta and Tumor Necrosis Factor Alpha Upregulation and Nuclear Factor Kappa B Activation in Skeletal Muscle from a Mouse Model of Chronic/Progressive Parkinson Disease.
    Author: Erekat N, Al-Jarrah MD.
    Journal: Med Sci Monit; 2018 Oct 22; 24():7524-7531. PubMed ID: 30344306.
    Abstract:
    BACKGROUND Skeletal muscle atrophy has been reported in patients with Parkinson disease (PD). The purpose of this study was to examine the potential implication of interleukin 1 beta (IL-1β), tumor necrosis factor alpha (TNFα), and nuclear factor kappa B (NF kappa B) in skeletal muscle atrophy following PD induction. MATERIAL AND METHODS Chronic Parkinsonism was induced in 10 albino mice by MPTP/probenecid treatment, while 10 other albino mice remained without treatment and were subsequently used as controls. Gastrocnemius muscles were examined for the expression of IL-1β and TNF-α, as well as the nuclear localization of NF kappa B, indicative of its activation, using immunohistochemistry in the 2 different groups. RESULTS IL-1β and TNF-α expression and NF kappa B nuclear localization were significantly higher in the PD skeletal muscle compared with those in the controls (P value <0.01). CONCLUSIONS The present data are indicative of an association of PD with IL-1β and TNF-α upregulation and NF kappa B activation in gastrocnemius muscles, potentially promoting the atrophy frequently observed in PD.
