OBJECTIVES We have previously reported that interleukin (IL)-6 is induced by hypoxic stimulation in cardiac myocytes. In the present study, we examined the induction of potent transcription factors of IL-6, nuclear factor (NF)-kappa B and NF-IL6, in cardiac myocytes subjected to hypoxia. METHODS Five different lengths of IL-6 promoter-luciferase reporter plasmids and three mutant plasmids, in...
Differential effects of leflunomide and methotrexate on cytokine production in rheumatoid arthritis.
BACKGROUND T cells have a pivotal role in RA. Leflunomide inhibits pyrimidine biosynthesis, to which T cells are especially susceptible, and therefore may have a different cytokine profile than methotrexate. MATERIALS AND METHODS Serum samples of 100 patients with RA, treated with leflunomide (n = 50) or methotrexate (n = 50), were collected at baseline, after 16 weeks and after 1 year's trea...
Requirements for human Th17 differentiation in the context of activated dendritic cells (DCs) are still emerging. Here, we demonstrate that several Toll-like receptor (TLR) ligands, particularly LPS and a synthetic lipoprotein, activate human DCs to direct increased human Th17 differentiation. Based on neutralization studies, IL1, IL6, and TGFbeta contributed to human Th17 differentiation induc...
Inflammation is linked clinically and epidemiologically to cancer, and NF-kappaB appears to play a causative role, but the mechanisms are poorly understood. We show that transient activation of Src oncoprotein can mediate an epigenetic switch from immortalized breast cells to a stably transformed line that forms self-renewing mammospheres that contain cancer stem cells. Src activation triggers ...
The authors tested the evolutionary genetic hypothesis that the functional form of an asymmetrically risky Gene × Environment interaction will differ as a function of age-related antagonistic pleiotropy (i.e., show opposite effects in young vs. old individuals). Previous studies have identified a polymorphism in the human IL6 promoter (rs1800795; IL6-74 G/C) that interacts with adverse socioenv...
Prostate cancer is the second leading form of cancer-related death in men. In a subset of prostate cancer patients, increased chemokine signaling IL8 and IL6 correlates with castrate-resistant prostate cancer (CRPC). IL8 and IL6 are produced by prostate epithelial cells and promote prostate cancer cell invasion; however, the mechanisms restraining prostate epithelial cell cytokine secretion are...
Inflammation is linked clinically and epidemiologically to cancer, and NF-kB appears to play a causative role, but the mechanisms are poorly understood. We show that transient activation of Src oncoprotein can mediate an epigenetic switch from immortalized breast cells to a stably transformed line that forms self-renewing mammospheres that contain cancer stem cells. Src activation triggers an i...
Murine plasmacytomas show a striking dependence on interleukin 6 (IL6) for their growth in vitro . Here, we present evidence suggesting that IL6 also plays an essential role in the in vivo development of these tumors . This conclusion is based on the finding that the tumorigenicity of an IL-6-dependent plasmacytoma cell line was increased -100-fold on transfection with an IL-6 expression vector...
We conducted a case-control study to investigate the influence of IL6 -174G/C (rs1800795) and -572C/G (rs1800796) genetic variants on the development of cerebral thrombosis in a Chinese population. This study included 305 cerebral infarction patients and 326 control subjects enrolled between May 2012 and May 2014. The genotyping of IL6 -174G/C (rs1800795) and -572C/G (rs1800796) polymorphisms w...
BACKGROUND Air pollutants have been linked to type 2 diabetes (T2D), hypothesized to act through inflammatory pathways and may induce interleukin-6 gene (IL6) in the airway epithelium. The cytokine interleukin-6 may impact on glucose homeostasis. Recent meta-analyses showed the common polymorphisms, IL6 -572G > C and IL6 -174G > C to be associated with T2D risk. These IL6 variants also influenc...
