Excess production of the proinflammatory IL6 has both local and systemic tumor-promoting activity in many cancers, including ovarian cancer. However, treatment of advanced ovarian cancer patients with a neutralizing IL6 antibody yielded little efficacy in a previous phase II clinical trial. Here, we report results that may explain this outcome, based on the finding that neutralizing antibodies ...

German cockroach extract synergistically regulates tumor necrosis factor-alpha (TNF-alpha)-induced interleukin (IL)-8 expression in human airway epithelial cells. The IL-8 promoter contains nuclear factor (NF)-kappaB, activating protein (AP)-1, and NF for IL-6 (NF-IL6) transcription factor binding regions. Because cockroach extract activates extracellular regulated kinase (ERK), a known activat...

Inflammation is a constant in Non-Alcoholic Fatty Liver Disease (NAFLD), although their relationship unclear. In transgenic zebrafish system with chronic systemic overexpression of human IL6 (IL6-OE) we show that inflammation can cause intra-hepatic accumulation triglycerides. Transcriptomics and proteomics analysis the IL6-OE liver revealed deregulation glycolysis/gluconeogenesis pathway, espe...

Hypoxia induces protective autophagy in glioblastoma cells and new therapeutic avenues that target this process may improve the outcome for glioblastoma patients. Recent studies have suggested that the autophagic process is upregulated in glioblastomas in response to extensive hypoxia. Hypoxia also induces the upregulation of a specific set of proteins and microRNAs (miRNAs) in a variety of cel...

OBJECTIVE To investigate overnight variations in absolute values and patterns of cytokines including interleukin 6 (IL6) and tumour necrosis factor alpha (TNFalpha) in rheumatoid arthritis (RA), and to relate any changes to those occurring in blood cortisol. METHODS A total of 16 people (8 female) with active RA and who had received no recent glucocorticoids were admitted overnight. Blood sam...

IL-6 is implicated in the pathogenesis of various neuroinflammatory and neurodegenerative disorders of the CNS. IL-6 signals via binding to either the membrane bound IL-6Rα (classic signaling) or soluble (s)IL-6Ra (trans-signaling) that then form a complex with gp130 to activate the JAK/STAT signaling pathway. The importance of classic versus trans-signaling in mediating IL-6 actions in the liv...

Interleukin-6 (IL6) is a pleiotropic inflammatory cytokine, which is implicated in the development and progression of several types of cancer. The -174G/C polymorphism of the IL6 gene controls serum levels of IL6 and may be associated with cancer risk, but the results from the published studies on the association between this polymorphism and cancer risk are conflicting. A comprehensive meta-an...

NF-IL6 was originally identified as a DNA binding protein regulating interleukin-1 (IL-1)-stimulated IL-6 expression. Direct cloning of NF-IL6 showed its homology with C/EBP, a hepatocyte- and adipocyte-specific transcription factor. This study showed that the expression of NF-IL6 messenger RNA (mRNA) increased markedly during the differentiation to a (mRNA) increased markedly during the differ...

The pubertal peak in onset of type 1 diabetes occurs earlier in girls than boys. We postulated that this sex difference might be mediated in part by estrogen or by genes regulated by estrogen, such as the interleukin-6 (IL6) gene. Previous studies concerning the role of an estrogen-sensitive single nucleotide polymorphism (SNP) in the IL6 promoter in type 1 diabetes have proved contradictory. W...
