Background: Interleukie-8 is a proinflammatory cytokine and a potent chemotactic and activation factor for neutrophils. It has been reported to be expressed in high levels by various cell types after immune stimulation and mediates neutrophil recruitment in host. Objectives: The aim of this study was to analysis of the relationship between single nucleotide polymorphisms (SNPs) at position -18...
Interleukin 8 (IL8) is an important chemokine that elicits host immune response against tuberculosis (TB). However, whether there is an association between IL8 gene polymorphism and TB susceptibility in the Chinese population is unknown. IL8 gene was amplified and sequenced to search for nucleotide polymorphisms among the Chinese population. Four single nucleotide polymorphisms (SNPs) were iden...
The uterine expression of the chemokine IL8 increases dramatically with the onset of labour both at term and preterm. The IL8 promoter contains binding sites for the transcription factors nuclear factor-kappa B (NFκB), activator protein-1 (AP-1), and CCAAT/enhancer-binding protein (CEBP). In this study we investigated the roles of these transcription factors in IL1B regulation of the IL8 gene i...
Imatinib, a targeted tyrosine kinase inhibitor, is the gold standard for managing chronic myeloid leukemia (CML). Despite its wide application, imatinib resistance occurs in 20-30% of individuals with CML. Multiple potential biomarkers have been identified to predict imatinib response; however, the majority of them remain externally uncorroborated. In this study, we set out to systematically id...
A growing number of studies indicate that chronic stress can accelerate tumor growth due to sustained sympathetic nervous system activation. Our recent findings suggest that chronic stress is associated with increased IL8 levels. Here, we examined the molecular and biological significance of IL8 in stress-induced tumor growth. Norepinephrine (NE) treatment of ovarian cancer cells resulted in a ...
Neutrophils are important cellular mediators in inflammatory bowel disease (IBD). Interleukin (IL)8, a powerful neutrophil chemoattractant, is found in increased quantities in inflamed mucosa, but the cells of origin are uncertain. IL8 gene expression was studied by in situ hybridisation in uninflamed intestinal tissue resected for colon carcinoma (n = 7) and in inflamed colonic tissue resected...
Abstract Hepatitis B–associated hepatocellular carcinoma (HCC) is often accompanied by severe vascular invasion and portal vein tumor thrombus, leading to a poor prognosis. However, the underlying mechanism of this disease remains obscure. In study, we demonstrate that hepatitis B virus (HBV)–encoded gene HBx induces high IL8 production through MEK–ERK signal activation, enhanced endothelial pe...
OBJECTIVES Periodontitis is an inflammatory disease characterized by connective tissue loss and alveolar bone destruction. Interleukin-8 (IL8) is important in the regulation of the immune response. The aim of this study was to analyze four polymorphisms in the IL8 gene in relation to chronic (CP) and aggressive (AgP) periodontitis. METHODS A total of 492 unrelated subjects were included in th...
Approximately 15 different alpha, or CXC, chemokines have thus far been isolated from 11 species of mammals. Among the best studied chemokines are the 12 human proteins that are encoded by 11 paralogous genes. In order to better understand the evolution and function of this group of genes, we isolated and characterized six novel GRO and GRO-related cDNA sequences from the cow (Bos taurus), the ...
AIM To assess the role of pro- and anti-inflammatory polymorphisms in gastric cancer susceptibility. PATIENTS AND METHODS We genotyped 12 polymorphisms in eight cytokine genes (Interleukin-1β -IL1B-, IL8, IL17A, IL17F, IL32, tumor necrosis factor-α -TNF-, IL1RN, IL10) in a case-control study of 147 patients with gastric cancer and 172 controls. RESULTS Single polymorphism analysis revealed ...
