Abstract/OtherAbstract:
Valosin-containing protein (VCP) may have a pivotal role in ubiquitin-dependent protein degradation and is implicated in the pathogenesis of neurodegenerative diseases. Skin studies from patients with amyotrophic lateral sclerosis (ALS) have shown unique abnormalities. We undertook a quantitative immunohistochemical study of VCP in the skin from patients with ALS and control participants. The proportion of VCP-positive (VCP+) cells in the epidermis in patients with ALS was significantly higher (p<0.001) than in controls. There was a significant positive relationship (r=0.59, p<0.01) between this proportion and duration of illness in patients with ALS. The optical density of VCP+ cells in the epidermis in patients with ALS was higher (p<0.001) than in controls. There was a significant positive relationship (r=0.61, p<0.01) between the immunoreactivity and duration of illness in patients with ALS. These data suggest that changes in VCP identified in skin from patients with ALS are likely to be related to the disease process.
