Considerable evidence indicates that free radical injury may underlie the pathologic changes in muscular dystrophies from mammalian and avian species. We have investigated the role of oxidative injury in muscle necrosis in mice with a muscular dystrophy due to a defect in the dystrophin gene (the mdx strain). In order to avoid secondary consequences of(More)
Several lines of evidence suggest that free radical mediated injury and oxidative stress may lead to muscle necrosis in the muscular dystrophies, including those related to defects in the dystrophin gene. We have examined muscle cell death using an in vitro assay in which the processes that lead to myofiber necrosis in vivo may be amenable to investigation(More)
Intestinal mucosal epithelial cells produce IL-8, a neutrophil chemoattractant that contributes to mucosal inflammation in various infectious and inflammatory diseases. However, the mediators involved and the molecular regulation of IL-8 production are poorly understood. As PGE2 is central in gut inflammation and modulates a variety of mucosal epithelial(More)
BACKGROUND & AIMS The mechanisms involved in the initiation of host mucosal inflammation in amebiasis are not fully understood. This study characterized the effect of Entamoeba histolytica components on interleukin 8 (IL-8) gene expression in human colonic cells. METHODS Colonic cells were stimulated with amebic proteins, secretory components, or live(More)
Although adenosine/uridine (AU)-rich sequences in the 3'-untranslated region (UTR) of the interleukin-8 (IL-8) gene have been suggested to contribute to its post-transcriptional regulation, the molecular basis whereby this occurs still needs to be understood. To investigate the role of the 3'-UTR on human IL-8 gene regulation, chimeric reporter genes were(More)
Objective: This study aims to explore the regulation of suppressor of cytokine signaling (SOCS1/3) on the differentiation of T cell and the role in Hashimoto’s thyroiditis (HT). Methods: The CD4+ T lymphocytes and B lymphocytes were separated from HT patients. The expression levels of SOCS1 and SOCS3 in CD4+ T cells were up-regulated using gene transfection(More)
