We then investigated the interaction between macrophages (cell line THP-1) and six different human cancer cell lines (four NSCLCs, one osteosarcoma, and one hepatoma) and its effect on IL-8 mRNA expression using a macrophage/cancer cell coculture system, IL-8 mRNA expression in lung cancer cells, and macrophages being measured separately after coculture in the presence or absence of six anti-inflammatory agents, i.e., pentoxifylline, aspirin, indomethacin, dexamethasone, celecoxib (a selective cyclooxygenase-2 inhibitor), and pyrrolidine dithiocarbamate, a specific nuclear factor kappaB (NF-kappaB) inhibitor.
Baseline HRQoL using the conventional assessments of EORTC QLQ-C30 and QLQ-HCC18, as well as C30 and HCC18 index-scores, significantly correlated with inflammatory indicators (IL-8 level and mIBI) in HCC patients.
We analyzed the gene expression of β-catenin, c-Myc and IL-8 in human HCC tissue by RT-PCR and immunohistochemistry and analyzed five variously differentiated HCC cell lines by Western blotting and migration and invasion assays to find markers for HCC diagnosis and HCC metastasis. mRNA expression of β-catenin was significantly higher in the tumor area compared to the non-tumor area and was more abundant in specimens of late-stage HCC.
Two human hepatoma cell lines (SK-Hep and Hep-G2) displayed a time- and dose-dependent increase in steady state levels of NCF/IL-8 mRNA and secretion of chemotactic activity in response to TNF and IL-1.
We examined the antiangiogenic effect against hepatocellular carcinoma (HCC) of the copper chelator trientine, especially focusing on the relationship between copper and interleukin-8 (IL-8), a potent angiogenic factor produced by hepatoma cells.
The objectives of the present study were: i) To investigate the association between soluble B7-H3 (sB7-H3) and cytokine levels of IL-17, IL-8 and IL-6 in the serum of patients with hepatocellular carcinoma (HCC); and ii) to determine their potential value for use in HCC diagnosis.
We observed that increased MIF serum levels correlated with higher levels of interleukin-8 (IL-8) in the sera of patients with HCC than in normal volunteers.
TAC-101 reduced IL-8 production without cytotoxicity and inhibited the progression of HCC in the orthotopic mouse model with decreased tumor IL-8 level.
By flow cytometry, we observed a significant IL-8 decrease which is closely related to the tumoral progression and chemotherapeutic resistance, especially in HCC.
To clarify the role(s) of interleukin 8 (IL-8) in chronic hepatitis B and hepatocellular carcinoma (HCC) in the woodchuck model, we cloned and characterized the woodchuck IL-8 cDNA and genomic DNA.
Expressions of glutathione S-transferase pi 1 (GSTP1), lysozyme (LYZ), C-X-C motif chemokine ligand 5 (CXCL5), interleukin-8 (IL8) and dickkopf WNT signaling pathway inhibitor 1 (DKK1), the five most highly expressed genes in the CSC cDNA microarray databases, were examined in 99 patients with HCC by real-time polymerase chain reaction (qRT-PCR), and their clinical significance was analyzed.
Cell-associated interleukin-8 antigen was present in SK-hepatoma and primary hepatocytes that had been incubated with macrophage-conditioned medium, tumor necrosis factor or interleukin-1 beta.
Overexpression of CPAP upregulates several STAT3 target genes such as IL-8 and CD44 that are involved in angiogenesis, and CPAP mRNA expression is positively correlated with the levels of both mRNAs in HCC.
