title: Ornithine decarboxylase gene expression in Castleman's disease.
abstract: Castleman's disease (CD) is a rare atypical lymphoproliferative disorder that is clinically and histologically heterogeneous and is associated with the risk of developing malignant lymphoma. Based on pathological findings CD is divided into two types: a localized form and a multicentric form. The clinical course differs in these two forms. We examined the molecular mechanisms that lie between benign and malignant disease, evaluating a possible implication of oncogenes in the pathogenesis. Since deregulated expression of the gene for ornithine decarboxylase (ODC) has been observed in a variety of human malignancies, we compared ODC expression between the localized and multicentric forms. Using northern blot analysis we found that ODC gene expression clearly differs between the localized and multicentric forms. The findings in this report indicate that the variable pattern of ODC gene expression in the different types of CD could be useful for examining the evolution of this disease.
