IL-8-induced CXCR2 down-regulation in circulating monocytes in hepatocellular carcinoma is partially dependent on MAGL.
    BMC cancer, 2023, Jul-04, Volume: 23, Issue:1

    CXC-chemokine receptor 2 (CXCR2) expression was found to be down-regulated on circulating monocytes of cancer patients. Here, we analyze the percentage of CD14. Flow cytometry was used to analyze the proportion of the CD14. A decrease in the proportion of the CD14. Overexpression of IL-8 drives CXCR2 down-regulation on circulating monocytes of HCC patients, which could be partially reversed by a MAGL inhibitor.

Acidic ascites inhibits ovarian cancer cell proliferation and correlates with the metabolomic, lipidomic and inflammatory phenotype of human patients.
    Journal of translational medicine, 2022, Dec-12, Volume: 20, Issue:1

    The poor prognosis of ovarian cancer patients is strongly related to peritoneal metastasis with the production of malignant ascites. However, it remains largely unclear how ascites in the peritoneal cavity influences tumor metabolism and recurrence. This study is an explorative approach aimed at for a deeper molecular and physical-chemical characterization of malignant ascites and to investigate their effect on in vitro ovarian cancer cell proliferation.. This study included 10 malignant ascites specimens from patients undergoing ovarian cancer resection. Ascites samples were deeply phenotyped by.  The overall extracellular (peritoneal) environment was alkaline, with pH of ascites at stage II-III = 7.51 ± 0.16, and stage IV = 7.78 ± 0.16. Ovarian cancer spheroids grew rapidly in a slightly alkaline environment. Decreasing pH of the cell culture medium suppressed tumor features, metabolic activity, adhesion, anti-apoptosis, and migratory ability. However, 10% ascites could prevent tumor cells from being affected by acidic pH. Metabolomics analysis identified stage IV patients had significantly higher concentrations of alanine, isoleucine, phenylalanine, and glutamine than stage II-III patients, while stage II-III patients had significantly higher concentrations of 3-hydroxybutyrate. pH was positively correlated with acetate, and acetate positively correlated with lipid compounds. IL-8 was positively correlated with lipid metabolites and acetate. Glutathione and carnitine were negatively correlated with cytokines IL-6 and chemokines (IL-8 & MCP-1).. Alkaline malignant ascites facilitated ovarian cancer progression. Additionally, deep ascites phenotyping by metabolomics and cytokine investigations allows for a refined stratification of ovarian cancer patients. These findings contribute to the understanding of ascites pathology in ovarian cancer.

Cytokines in peritoneal fluid of ovarian neoplasms.
    Journal of obstetrics and gynaecology : the journal of the Institute of Obstetrics and Gynaecology, 2020, Volume: 40, Issue:3

    The aim of this study was to evaluate cytokine levels (IL-2, IL-8, TNF-α, IL-5, IL-6 and IL-10) in the peritoneal fluid in non-neoplastic tumours, benign ovarian neoplasms and malignant ovarian neoplasms. Peritoneal fluid or ascites was collected from 117 patients with neoplastic and non-neoplastic ovarian tumours. Cytokine levels were assessed by ELISA. The unpaired groups were compared by the Kruskal-Wallis test with Dunn's post-test. Higher IL-6 levels were found in malignant neoplasms when compared to non-neoplastic tumours (

Ascites-derived ALDH+CD44+ tumour cell subsets endow stemness, metastasis and metabolic switch via PDK4-mediated STAT3/AKT/NF-κB/IL-8 signalling in ovarian cancer.
    British journal of cancer, 2020, Volume: 123, Issue:2

    Ovarian cancer is characterised by frequent recurrence due to persistent presence of residual cancer stem cells (CSCs). Here, we identify and characterise tumour subsets from ascites-derived tumour cells with stemness, metastasis and metabolic switch properties and to delineate the involvement of pyruvate dehydrogenase kinase 4 (PDK4) in such process.. Ovarian cancer cells/cell lines derived from ascites were used for tumourspheres/ALDH+CD44+ subset isolation. The functional roles and downstream signalling of PDK4 were explored. Its association with clinical outcome of ovarian cancer was analysed.. We demonstrated enhanced CSC characteristics of tumour cells derived from ovarian cancer ascites, concomitant with ALDH and CD44 subset enrichment and high PDK4 expression, compared to primary tumours. We further showed tumourspheres/ALDH+CD44+ subsets from ascites-derived tumour cells/cell lines with CSC properties and enhanced glycolysis. Clinically, PDK4 expression was correlated with aggressive features. Notably, blockade of PDK4 in tumourspheres/ALDH+CD44+ subsets led to inhibition of CSC characteristics, glycolysis and activation of STAT3/AKT/NF-κB/IL-8 (signal transducer and activator of transcription 3/protein kinases B/nuclear factor-κB/interleukin-8) signalling. Conversely, overexpression of PDK4 in ALDH-CD44- subsets exerted the opposite effects.. Ascites-derived ALDH+CD44+ tumour cell subsets endow stemness, metastatic and metabolic switch properties via PDK4-mediated STAT3/AKT/NF-κB/IL-8 signalling, suggesting PDK4 as a viable therapeutic molecular target for ovarian cancer management.

Genetic variants of TRAF6 modulate peritoneal immunity and the risk of spontaneous bacterial peritonitis in cirrhosis: A combined prospective-retrospective study.
    Scientific reports, 2017, 07-07, Volume: 7, Issue:1

    Alterations of the innate immunity contribute to the development of spontaneous bacterial peritonitis (SBP) in liver cirrhosis. Given its role in immune signaling, antimicrobial function, and macrophage differentiation, we hypothesized that genetic polymorphisms of TRAF6 modulate the risk of SBP. Thus, we determined theTRAF6 haplotype in 432 patients with cirrhosis and ascites using the haplotype-tagging single nucleotide polymorphisms rs331457 and rs5030419. In addition, peritoneal macrophages were immunomagnetically isolated and characterized. Overall, 122 (28%) patients had an episode of SBP. In the combined prospective-retrospective analysis the frequency of SBP differed between the four haplotypes (P = 0.014) and was the highest in 102 patients carrying the rs331457 but not the rs5030419 variant, when compared to other haplotypes (odds ratio 1.95 [1.22-3.12]) or to the wild-type (odds ratio 1.71 [1.04-2.82]). This association was confirmed in multivariate logistic regression (adjusted odds ratio 2.00 [1.24-3.22]) and in prospective sensitivity analysis (hazard ratio 2.09 [1.08-4.07]; P = 0.03). The risk haplotype was associated with lower concentrations of the immune activation marker soluble CD87 in ascitic fluid and with a decreased expression of IL-6 and CXCL8 in isolated peritoneal macrophages. In conclusion, genetic polymorphisms of TRAF6 are associated with decreased peritoneal immune activation and an increased risk of SBP.

Cytokine profiling of ascites at primary surgery identifies an interaction of tumor necrosis factor-α and interleukin-6 in predicting reduced progression-free survival in epithelial ovarian cancer.
    Gynecologic oncology, 2015, Volume: 138, Issue:2

    Epithelial ovarian cancer (EOC) typically presents with advanced disease. Even with optimal debulking and response to adjuvant chemotherapy, the majority of patients will have disease relapse. We evaluated cytokine and chemokine profiles in ascites at primary surgery as biomarkers for progression-free survival (PFS) and overall survival (OS) in patients with advanced EOC.. Retrospective analysis of patients (n =70) who underwent surgery at Roswell Park Cancer Institute between 2002 and 2012, followed by platinum-based chemotherapy.. The mean age at diagnosis was 61.8 years, 85.3% had serous EOC, and 95.7% had stage IIIB, IIIC, or IV disease. Univariate analysis showed that ascites levels of tumor necrosis factor (TNF)-α were associated with reduced PFS after primary surgery. Although the ascites concentration of interleukin (IL)-6 was not by itself predictive of PFS, we found that stratifying patients by high TNF-α and high IL-6 levels identified a sub-group of patients at high risk for rapid disease relapse. This effect was largely independent of clinical prognostic variables.. The combination of high TNF-α and high IL-6 ascites levels at primary surgery predicts worse PFS in patients with advanced EOC. These results suggest an interaction between ascites TNF-α and IL-6 in driving tumor progression and resistance to chemotherapy in advanced EOC, and raise the potential for pre-treatment ascites levels of these cytokines as prognostic biomarkers. This study involved a small sample of patients and was an exploratory analysis; therefore, findings require validation in a larger independent cohort.

Interleukin 6 and interleukin 8 play important roles in systemic inflammatory response syndrome of meconium peritonitis.
    Surgery today, 2012, Volume: 42, Issue:5

    Meconium peritonitis is caused by an intestinal perforation that may occur in the fetus, followed by severe chemical peritonitis, resulting in high morbidity.. We have experienced six patients with meconium peritonitis. Cystic drainage was performed soon after birth for all patients. We investigated the concentrations of several cytokines and a chemokine (interleukin 8) in the ascites from the six patients with meconium peritonitis. In two patients we also measured the serum cytokines and chemokine level just after birth.. Interleukin 6 and interleukin 8 concentrations were very high in the cyst or ascites just after birth. In the serum taken from two patients, the levels of interleukin 6 and interleukin 8 were also high. In five patients who underwent drainage of cysts after birth, systemic inflammation could not be completely suppressed before curative surgery.. Interleukin 6 and interleukin 8 play important roles in the inflammatory response syndrome associated with meconium peritonitis, and drainage of cystic fluid did not completely suppress this inflammation. To lessen the high morbidity of meconium peritonitis, efforts should be made to suppress the inflammatory response using new treatment strategies, such as administration of steroids or anti-cytokine therapy to supplement cystic drainage.

Ovarian ascites-derived Hospicells promote angiogenesis via activation of macrophages.
    Cancer letters, 2012, Dec-29, Volume: 326, Issue:1

    Within the microenvironment, Carcinoma-associated mesenchymal stem cells (Hospicells) are able to influence ovarian tumor development via, among others, the facilitation of angiogenesis in the tumor site allowing an accelerated tumor growth. We demonstrate the presence of a chemotactism between endothelial cells and Hospicells, and a cell line specific increased secretion of pro-angiogenic cytokines such as IL-6, IL-8 and VEGF from ovarian adenocarcinoma cells. Hospicells are also able to attract and activate macrophages to a M2 phenotype and allow them to secrete a huge quantity of pro-angiogenic cytokines, favorable to tumor progression of all the associated ovarian adenocarcinoma cells tested.

Prognostic significance of IL-6 and IL-8 ascites levels in ovarian cancer patients.
    BMC cancer, 2011, May-30, Volume: 11

    The acellular fraction of epithelial ovarian cancer (EOC) ascites promotes de novo resistance of tumor cells and thus supports the idea that tumor cells may survive in the surrounding protective microenvironment contributing to disease recurrence. Levels of the pro-inflammatory cytokines IL-6 and IL-8 are elevated in EOC ascites suggesting that they could play a role in tumor progression.. We measured IL-6 and IL-8 levels in the ascites of 39 patients with newly diagnosed EOC. Commercially available enzyme-linked immunosorbent assay (ELISA) was used to determine IL-6 and IL-8 ascites levels. Ascites cytokine levels were correlated with clinicopathological parameters and progression-free survival.. Mean ascites levels for IL-6 and IL-8 were 6419 pg/ml (SEM: 1409 pg/ml) and 1408 pg/ml (SEM: 437 pg/ml) respectively. The levels of IL-6 and IL-8 in ascites were significantly lower in patients that have received prior chemotherapy before the surgery (Mann-Whitney U test, P = 0.037 for IL-6 and P = 0.008 for IL-8). Univariate analysis revealed that high IL-6 ascites levels (P = 0.021), serum CA125 levels (P = 0.04) and stage IV (P = 0.009) were significantly correlated with shorter progression-free survival. Including these variables in a multivariate analysis revealed that elevated IL-6 levels (P = 0.033) was an independent predictor of shorter progression-free survival.. Elevated IL-6, but not IL-8, ascites level is an independent predictor of shorter progression-free survival.

Signal mechanisms of vascular endothelial growth factor and interleukin-8 in ovarian hyperstimulation syndrome: dopamine targets their common pathways.
    Human reproduction (Oxford, England), 2010, Volume: 25, Issue:3

    Ovarian hyperstimulation syndrome (OHSS) is a serious complication of ovarian stimulation with massive ascites, pleural effusion and hemoconcentration. The pathophysiological signal mechanisms of OHSS are still unclear and merit further investigation.. Various angiogenic cytokines of follicular fluid and ascites of patients with risk of OHSS were measured, and examined for inducing endothelial permeability. These include vascular endothelial growth factor (VEGF), interleukin (IL)-6, IL-8, basic fibroblast growth factor, tumor necrosis factor-alpha, IL-1alpha, IL-1beta and platelet-derived growth factor. We explore the molecular signal pathways of major contributing cytokines in granulosa-lutein cells and endothelial cells possibly involved in OHSS.. Neutralizing antibodies of VEGF or IL-8 significantly decreased follicular fluid- and ascites-induced endothelial permeability. Human chorionic gonadotrophin induced VEGF secretion of granulosa-lutein cells through the Sp1 and CREB dependent pathways. IL-8 activated CXCR1/2 of endothelial cells leading to VEGF receptor (VEGFR)-2 transactivation. Both VEGF and IL-8 of follicular fluid enhanced endothelial permeability via VEGFR-2-mediated Rho/Rock activation, actin polymerization and phosphorylations of VE-cadherin and occludin, resulting in opening of adherens junctions and tight junctions. Dopamine (2 microM) inhibited follicular fluid-induced VEGFR-2 signals and endothelial permeability, without diminishing migration and tube formation.. Our results suggest that VEGF and IL-8 secreted from corpora luteae may play major roles in OHSS. Delineation of signal pathways would be helpful for treatment. Dopamine may block VEGF- and IL-8-induced endothelial permeability by inhibiting common VEGFR-2 dependent signals.

[Differences in serum and ascites cytokine production caused by Gram-positive or -negative bacterial infection in patients with multiple organ dysfunction syndrome].
    Nan fang yi ke da xue xue bao = Journal of Southern Medical University, 2010, Volume: 30, Issue:7

    To observe the differences in the cytokine levels in the serum and ascites caused by Gram-positive or Gram-negative bacterial infection in patients with multiple organ dysfunction syndrome (MODS).. The cytokines in the serum and ascites of the patients were examined by enzyme-linked immunosorbent assay in 27 patients with MODS due to Gram-positive (n=13) or Gram-negative (n=14) bacterial infection at day 1.. The levels of LPS and TNF-a were higher in the patients with Gram-negative bacterial infection than in patients with Gram-positive infection (P<0.05), but the levels of IL-6, IL-8 and IL-10 remained comparable between the two groups (P>0.05).. Testing of LPS and TNF-a in the serum and ascites of patients with MODS caused by Gram-positive or -negative bacterial infection may help to identify the pathogens for peritonitis resulting in MODS.

Interleukin-8 in the blood serum of patients with alcoholic liver disease.
    Medical science monitor : international medical journal of experimental and clinical research, 2006, Volume: 12, Issue:5

    The influence of the immune system on the development of alcoholic liver disease has recently been the object of attention. However, the connection between alcohol consumption, altered immune response, and development of changes in the liver has not been fully explained. The aim of the present study was to evaluate serum IL-8 concentration in patients with chronic alcoholic liver disease.. 85 patients with different types of ALD and 35 healthy subjects were enrolled in the study. Serum IL-8 concentration was evaluated with the ELISA immunoenzymatic method. IL-8 in liver tissue was measured by the indirect immunofluorescence method.. There was a significant correlation between IL-8 concentration and AST, ALP, GGT, total bilirubin and albumin levels in blood serum. A significantly higher concentration of IL-8 was seen in all the groups of ALD patients. The highest values were found in patients with chronic alcoholic hepatitis, and the lowest in those with fatty liver. Significantly higher values were found in patients with ascites or encephalopathy in comparison to those without any features of portal hypertension and/or insufficiency of the liver cells. A high concentration of the tested cytokine is a disadvantageous prognostic factor in patients with ALD.. IL-8 appears to be an important factor in liver pathology in patients with ALD, especially in the development of the inflammatory process.

Dendritic cell subsets differentially regulate angiogenesis in human ovarian cancer.
    Cancer research, 2004, Aug-15, Volume: 64, Issue:16

    Angiogenesis is essential for both primary and metastatic tumor growth. Tumor blood vessel formation is complex and regulated by many factors. Ovarian carcinomas have a poor prognosis, often associated with multifocal intraperitoneal dissemination accompanied by intense neovascularization. To examine tumor angiogenesis in the tumor microenvironment, we studied malignant ascites of patients with untreated ovarian carcinoma. We observed high numbers of plasmacytoid dendritic cells (PDCs) and significant stromal-derived factor (CXCL-12/SDF)-1 in their malignant ascites, attracting PDCs into the tumor environment. We now show that tumor-associated PDCs induced angiogenesis in vivo through production of tumor necrosis factor alpha and interleukin 8. By contrast, myeloid dendritic cells (MDCs) were absent from malignant ascites. MDCs derived in vitro suppressed angiogenesis in vivo through production of interleukin 12. Thus, the tumor may attract PDCs to augment angiogenesis while excluding MDCs to prevent angiogenesis inhibition, demonstrating a novel mechanism for modulating tumor neovascularization. Because dendritic cells (DCs) have long been known to affect tumor immunity, our data also implicate DCs in regulation of tumor neoangiogenesis, suggesting a novel role of DCs in tumor pathology.

Role of ether-linked lysophosphatidic acids in ovarian cancer cells.
    Journal of lipid research, 2002, Volume: 43, Issue:3

    Naturally occurring alkyl- and alkenyl-lysophosphatidic acids (al-LPAs) are detected and elevated in ovarian cancer ascites compared with ascites from non-malignant diseases. Here we describe the biological functions and signaling properties of these ether-linked LPAs in ovarian cancer cells. They are elevated and stable in ovarian cancer ascites, which represents an in vivo environment for ovarian cancer cells. They stimulated DNA synthesis and proliferation of ovarian cancer cells. In addition, they induced cell migration and the secretion of a pro-angiogenic factor, interleukin-8 (IL-8), in ovarian cancer cells. The latter two processes are potentially related to tumor metastasis and angiogenesis, respectively. Al-LPAs induced diverse signaling pathways in ovarian cancer cells. Their mitogenic activity depended on the activation of the G(i/o) protein, phosphatidylinositol-3 kinase (PI3K), and mitogen-activated protein (MAP) kinase kinase (MEK), but not p38 mitogen activated protein kinase (MAP kinase). S473 phosphorylation of protein kinase B (Akt) by these lipids required activation of the G(i/o) protein, PI3K, MEK, p38 MAP kinase, and Rho. However, T308 phosphorylation of Akt stimulated by al-LPAs did not require activation of p38 MAP kinase. On the other hand, cell migration induced by al-LPAs depended on activities of the G(i/o) protein, PI3K, and Rho, but not MEK. These data suggest that ether-linked LPAs may play an important role in ovarian cancer development.

Ascites of severe acute pancreatitis in rats transcriptionally up-regulates expression of interleukin-6 and -8 in vascular endothelium and mononuclear leukocytes.
    Digestive diseases and sciences, 2000, Volume: 45, Issue:2

    The molecular mechanisms that link acute pancreatitis and multiple organ failure remain unknown. We examined the effect of ascitic fluids prepared from rats with experimental necrotizing pancreatitis on the expression of interleukin (IL) -6 and IL-8 in human umbilical vein endothelial cells (HUVEC) and human monocytic THP-1 cells. Incubation of HUVEC or THP-1 cells with the ascitic fluids resulted in a concentration-dependent up-regulation of the cytokine expression with comparable mRNA induction. Electrophoretic mobility shift assay revealed that the ascitic fluids increased the nuclear factor-kappaB (NF-kappaB) and NF-IL6 binding activities. Intraperitoneal injection of ascitic fluids into healthy rats induced the activation of NF-kappaB in the infiltrating leukocytes in the lung. Our results suggested that ascitic fluids may play a role in the pathophysiology of severe acute pancreatitis through the activation of transcription factors and consequent cytokine productions in distant organs.

Graded experimental acute pancreatitis: monitoring of a renewed rabbit model focusing on the production of interleukin-8 (IL-8) and CD11b/CD18.
    European journal of gastroenterology & hepatology, 1999, Volume: 11, Issue:2

    To establish and monitor a rabbit model of graded severity of acute pancreatitis to test the hypothesis that interleukin-8 (IL-8) and the adhesion molecule complex CD11b/CD18 are involved in the development of systemic complications in severe acute pancreatitis.. Acute pancreatitis induction in rabbits by duct ligation with or without infusion of 5.0% or 0.5% chenodeoxycholic acid or 0.9% saline. Control animals underwent laparotomy. The animals were monitored biochemically, histologically and immunohistochemically.. Increased serum levels of IL-8, tumour necrosis factor alpha (TNF-alpha), amylase and lipase were found in the chenodeoxycholic acid groups when compared with the saline, duct-ligated or control groups. Leukopenia, hypocalcaemia, and hyperglycaemia were marked in the 5.0% chenodeoxycholic acid group as compared to the saline, duct-ligated and control groups. Histologically, the 5.0% chenodeoxycholic acid group manifested a significant degree of pancreatic necrosis and neutrophil infiltration. The lungs of these animals showed acute lung injury and a significant up-regulation of CD11b/CD18. IL-8 was produced in pancreatic acinar and ductal cells. A significantly large output of ascitic fluid was seen in the 5.0% chenodeoxycholic acid group.. The rabbit models of acute pancreatitis are reliable in that enzymatic and histological evidence of acute pancreatitis with or without systemic complications developed. IL-8 is produced locally in pancreatic acinar and ductal cells and significantly increased in peripheral blood during severe but not mild pancreatitis. The expression of the adhesion molecule complex CD11b/CB18 is significantly increased in lung tissue during severe acute pancreatitis with acute lung injury. IL-8 and CD11b/CB18 are involved in the pathogenesis of severe acute pancreatitis but not of mild oedematous pancreatitis.

Prognostic importance of serial cytokine changes in ascites and pleural effusion in women with severe ovarian hyperstimulation syndrome.
    Fertility and sterility, 1999, Volume: 72, Issue:2

    To determine the prognostic value of various cytokine levels in ascites and pleural effusion during the evolution of severe ovarian hyperstimulation syndrome (OHSS).. A longitudinal study.. University teaching hospital.. Twenty patients with severe OHSS who required either paracentesis or thoracentesis or both from whom ascites (n = 56) or pleural effusion (n = 12) samples were obtained. Control peritoneal fluid was obtained from 20 patients undergoing ovarian stimulation for IVF.. Abdominal paracentesis for tense ascites and thoracentesis for massive pleural effusion. Control peritoneal fluid was obtained before oocyte retrieval.. Levels of interleukin-1 beta (IL-1 beta), interleukin-6 (IL-6), interleukin-8 (IL-8), tumor necrosis factor-alpha (TNF-alpha), vascular endothelial growth factor (VEGF), E2, and progesterone concentrations in ascites and pleural effusion.. Levels of VEGF and IL-6 in ascites dropped significantly during the course of OHSS and were not correlated with E2 concentrations. Levels of VEGF were significantly correlated with levels of IL-1 beta, IL-8, and TNF-alpha, as well as progesterone concentrations, hematocrit, and white blood cell counts. None of the cytokine levels measured in pleural effusion were correlated with the course of OHSS.. These results suggest that local cytokines might be involved in the evolution of severe OHSS and possibly serve as prognostic markers for this syndrome.

IT 9302, a synthetic interleukin-10 agonist, diminishes acute lung injury in rabbits with acute necrotizing pancreatitis.
    Surgery, 1998, Volume: 124, Issue:3

    Proinflammatory cytokines (eg, tumor necrosis factor [TNF]-alpha, interleukin [IL]-1 and Il- 8) are believed to play an important role in the pathogenesis of acute necrotizing pancreatitis (ANP) and its systemic complications. Recently, IL-10 has emerged as a major anti-inflammatory cytokine, inhibiting the secretion and activities of inflammatory cytokines. Further, a protective effect of IL-10 has recently been shown in experimental acute pancreatitis. The purpose of this study was to test the potential role of a newly developed IL-10 agonist, IT 9302, in a model of ANP in rabbits.. ANP was induced in 18 rabbits by retrograde injection of 5% chenodeoxycholic acid in the pancreatic duct, followed by duct ligation. The rabbits were allocated to pretreatment with intravenous physiologic saline solution or IT 9302 (200 micrograms/kg) 30 minutes before the induction of ANP.. Injection of IT 9302 resulted in a significant reduction in the blood levels of TNF-alpha and IL-8 from 3 to 6 hours. IT 9302 also reduced the amount of ascitic fluid and significantly inhibited neutrophil infiltration and margination, as well as the number of CD11b- and CD18-positive cells in the lung tissues. By contrast, the local pancreatic necrosis, as well as the biochemical changes such as serum amylase, lipase, and calcium, was sever and similar in both groups. Survival was improved significantly after treatment with IT 9302.. As expected, IT 9302 cannot change the degree of ANP induced by 5% bile acid but does reduce mortality rates and the development of acute lung injury, probably through the inhibition of circulating levels of TNF-alpha, IL-8, and the expression of the adhesion molecule complex CD11b/CD18.

Evidence for an unknown component of pancreatic ascites that induces adult respiratory distress syndrome through an interleukin-1 and tumor necrosis factor-dependent mechanism.
    Surgery, 1997, Volume: 122, Issue:2

    The development of acute respiratory distress syndrome (ARDS) during acute pancreatitis is associated with interleukin (IL)-1 and tumor necrosis factor (TNF) gene expression within the pulmonary parenchyma. Although activated pancreatic enzymes have been thought to mediate pancreatitis-induced ARDS, they are not capable of inducing cytokine production in vitro. We hypothesized that IL-1 and TNF production in the lungs is essential to the development of ARDS and is induced by a mediator released from the inflamed pancreas.. Pancreatic ascites was obtained from rats after induction of bile-salt pancreatitis, cultured, and assayed for IL-1, TNF, IL-6, IL-8, IL-10, interferon-gamma, and endotoxin. Sterile, cytokine-free ascites or saline (control) was subsequently administered intravenously (20 ml/kg) to healthy rats and to IL-1 R1 or TNF R1 knockout mice.. Animals administered intravenous ascites had a 30-fold rise in pulmonary IL-1 and TNF mRNA, as well as increased alveolar leukocytes and protein. Knockout animals devoid of active IL-1 or TNF receptors failed to develop increased alveolar protein or leukocytes.. A component of pancreatic ascites other than activated enzymes, bacteria, or inflammatory cytokines is capable of inducing ARDS in healthy animals. The mechanism appears to be directly attributable to the activity of pulmonary IL-1 and TNF.

Monocyte chemoattractant protein-1 stimulates tumor necrosis and recruitment of macrophages into tumors in tumor-bearing nude mice: increased granulocyte and macrophage progenitors in murine bone marrow.
    Experimental hematology, 1995, Volume: 23, Issue:9

    Monocyte chemoattractant protein-1 (MCP-1) belongs to the newly recognized "chemokine" superfamily of activation-inducible cytokines. We report here that MCP-1 gene-transferred mouse myeloma cells modulate tumor necrosis in myeloma-bearing nude mice. We established an MCP-1-producing myeloma cell line (X63-MCP-1) by transfection with human MCP-1 cDNA as well as interleukin-8-producing X63 cells (X63 IL-8). Each cell line showed the same growth characteristics in vitro, and 1 x 10(7) cells per mouse were injected into the peritoneal cavity resulting in the formation of tumors. Hematologic studies, including peripheral white blood cell counts and differentiation, showed no differences among the groups. They formed tumors in the same manner, which we observed from weeks 2.5 to 9. MCP-1 mice showed more tumor necrosis and infiltration of the macrophages into the tissue surrounding the tumor. In situ hybridization, using a partial cDNA as a probe, showed that macrophages contained MCP-1 mRNA. Bone marrow cell colony-forming assay showed a greater number of both granulocyte and macrophage colonies in MCP-1 mouse femur than in those of controls or interleukin-8 mice. MCP-1 has no direct stimulatory activity on stem cells, but longer exposure to MCP-1 in vivo might stimulate both granulocyte and macrophage progenitors and recruitment of macrophages into tumors, and it might explain the antitumor activity of macrophages in tumor-bearing nude mice.

Treatment of cancer ascites by intraperitoneal administration of a streptococcal preparation OK-432 with fresh human complement--role of complement-derived chemotactic factor to neutrophils.
    International journal of immunopharmacology, 1986, Volume: 8, Issue:7

    The role of complement in the polymorphonuclear leukocyte (PMN)-mediated tumor cell destruction in cancer ascites was investigated in relation to a streptococcal preparation OK-432, a so-called biological response modifier. Incubation of OK-432 with fresh human serum at 37 degrees C for 60 min resulted in the generation of C3a and C5a chemotactic factors. Intraperitoneal (i.p.) injection of the mixture to a patient with cancer ascites revealed an accumulation of PMNs in the ascitic fluid for a longer period with a rapid reduction of the ascitic fluid, than an intraperitoneal injection of OK-432 alone examined in the same patient. PMNs were found to invade clusters of the tumor cells and then form rosettes followed by the destruction of tumor cells. These findings induced by OK-432 continued over 10 days in the presence of fresh serum, while diminished within 3-4 days when OK-432 alone was injected. When fresh human plasma or fresh frozen plasma was used instead of serum and i.p. injected with OK-432 avoiding preincubation, the same cytological and clinical changes were observed in other patients. These data strongly indicate that OK-432 activates human complement either in vitro or in the peritoneal cavity, and induces PMNs to accumulate in the ascitic fluid. Although the mechanism of killing of tumor cells by PMNs is obscure, addition of human serum or plasma to i.p. use of OK-432 seems to be valuable for the management of patients with malignant ascites.
