Serum cytokine levels of interleukin-1beta, -6, -8, tumour necrosis factor-alpha and vascular endothelial growth factor in breast cancer patients treated with tamoxifen and supplemented with co-enzyme Q(10), riboflavin and niacin.
Plasma vascular endothelial growth factor and interleukin-8 as biomarkers of antitumor efficacy of a prototypical erbB family tyrosine kinase inhibitor.

Increased activation of NF-kappaB and high levels of the expression of interleukin (IL)-1beta mRNA and IL-8 mRNA were detected in biopsy specimens from patients with ulcerative colitis.
(1) The expression of IL-1beta mRNA and IL-8 mRNA was increased significantly in patients with UC, as compared with that in the control specimens (P < 0.05) and had a significant positive correlation with NF-kappaB DNA binding activity (r = 0.8363, P < 0.05; r = 0.6024, P < 0.05, respectively).
We conclude that 1) colorectal carcinogenesis is accompanied by increased synthesis and release of proinflammatory cytokines such as IL-6 and IL-8; 2) simvastatin therapy results in a decrease in serum level of proinflammatory cytokines, especially IL-6 in CRC and 3) simvastatin inhibits release of IL-8 and IL-6 from colorectal cell lines.
Salmon and king crab trypsin stimulate interleukin-8 and matrix metalloproteinases via protease-activated receptor-2 in the skin keratinocytic HaCaT cell line.
MicroRNA-218 acts by repressing TNFR1-mediated activation of NF-κB, which is involved in MUC5AC hyper-production and inflammation in smoking-induced bronchiolitis of COPD.
Decreased FoxO3A in COPD cells was associated with increased phosphorylation of EGFR, Akt and FoxO3A and treatment with quercetin, LY294002 or erlotinib increased nuclear FoxO3A and decreased IL-8 and phosphorylation of Akt, EGFR and FoxO3A, Compared with control, elastase/LPS-exposed mice showed decreased nuclear FoxO3A, increased chemokines and phosphorylation of EGFR and Akt.
Theophylline induced a sixfold increase in HDAC activity in COPD AM lysates and significantly enhanced dexamethasone suppression of induced IL-8 release, an effect that was blocked by the HDAC inhibitor trichostatin A.
The findings reported here demonstrate that SN38 (the active metabolite of CPT-11) induces the tyrosine phosphorylation of EGFR within 5 min, followed by the induction of transcripts and/or proteins of the heparin-binding EGF-like growth factor, amphiregulin, transforming growth factor-alpha, and interlukin-8 (IL-8) in AGS gastric cancer cells.
Expression of tissue PPARgamma, tissue levels of IL-1beta and IL-8, and plasma concentration of gastrin were significantly higher in H. pylori-positive GC compared to controls, but H. pylori eradication significantly reduced these parameters.
