Project description:Changes of Cytokines and chemokines profiles were sucessfully determined between mouse non-treated vs LPS treated pregnant uteri using Qiagen PCR array. Pregnant mouse (FVB strain E8.5-9.5) were treated with LPS(2.5ug/mouse) or saline as control. 8h- or 16-h later, uteri tissues (N=3) were collected.

Project description:Located in the perisinusoidal space of Disse, hepatic stellate cells (HSCs) communicate with all other liver cell types by physical association and / or by producing cytokines and chemokines. In liver disease and folllowing liver transplantation, elevated levels of endotoxin (bacterial lipopolysaccharide: LPS) stimulate HSCs to produce increased amounts of cytokines and chemokines. Transcriptomic analysis of cultured HSCs stimulated with LPS yields a survey of expression changes which potentially modulate the hepatic inflammatory and immune responses.

Transcriptomic analysis of cultured HSCs stimulated with LPS yields a survey of expression changes which potentially modulate the hepatic inflammatory and immune responses. In two independent experiments, rat HSCs were cultured with or without 10 ng/ml LPS for 1h and 24h, then harvested for microarray analysis (i.e., 8 samples). In the first of these experiments, cells also were also harvested after 3, 6 and 12 hours of LPS treatment, for a total of 11 samples.

Project description:We examined the major patterns of changes in gene expression in mouse splenic B cells in response to stimulation with 33 single ligands for 0.5, 1, 2, and 4 h. We found that ligands known to directly induce or costimulate proliferation, namely, anti-IgM (anti-Ig), anti-CD40 (CD40L), LPS, and, to a lesser extent, IL-4 and CpG-oligodeoxynucleotide (CpG), induced significant expression changes in a large number of genes. The remaining 28 single ligands produced changes in relatively few genes, even though they elicited measurable elevations in intracellular Ca2+ and cAMP concentration and/or protein phosphorylation, including cytokines, chemokines, and other ligands that interact with G protein-coupled receptors. A detailed comparison of gene expression responses to anti-Ig, CD40L, LPS, IL-4, and CpG indicates that while many genes had similar temporal patterns of change in expression in response to these ligands, subsets of genes showed unique expression patterns in response to IL-4, anti-Ig, and CD40L.

Project description:Neutrophil gene transcription following lipopolysaccharide exposure. Microarray analysis of lipopolysaccharide-treated human neutrophils. Neutrophils respond to infection by degranulation, release of reactive oxygen intermediates, and secretion of chemokines and cytokines; however, activation of neutrophil transcriptional machinery has been little appreciated. Recent findings suggest that gene expression may represent an additional neutrophil function after exposure to lipopolysaccharide (LPS). We performed microarray gene expression analysis of 4,608 mostly nonredundant genes on LPS-stimulated human neutrophils. Analysis of three donors indicated some variability but also a high degree of reproducibility in gene expression. Twenty-eight verifiable, distinct genes were induced by 4 h of LPS treatment, and 13 genes were repressed. Genes other than cytokines and chemokines are regulated; interestingly, genes involved in cell growth regulation and survival, transcriptional regulation, and interferon response are among those induced, whereas genes involved in cytoskeletal regulation are predominantly repressed. In addition, we identified monocyte chemoattractant protein-1 as a novel LPS-regulated chemokine in neutrophils. Included in these lists are five clones with no defined function. These data suggest molecular mechanisms by which neutrophils respond to infection and indicate that the transcriptional potential of neutrophils is greater than previously thought.

Project description:Neutrophil activation plays a critical role in the inflammatory response to gram-negative bacterial infections. Lipopolysaccharide (LPS) from gram-negative bacterial has been shown to be a major mediator of neutrophil activation to produce pro-inflammatory cytokines, chemokines and ROS which are important to tissue damage in LPS induced septic shock. We used microarrays to detail the global gene expression of neutrophils from miR-125a+/+ and miR-125a-/- mice after LPS stimulation.

Project description:This study investigated the global effect of carbon monoxide (CO) gas (250 ppm) on LPS- induced gene expression in THP-1 cells. CO predominantly suppresses LPS-induced gene response. Of the CO-suppressed genes, 18% were transcription factors and most others were cytokines, chemokines and immune response genes. Sequence analysis B binding siteskappafound that 81% of the gene promoters have putative NF- These results suggest that CO inhibits LPS-induced inflammatory B signaling pathwayresponse through regulating NF- The microarrays were performed on THP-1 cells, a human monocytic cell line. Cells were treated with or without LPS (1 ug/ml) in presence or absence of carbon monoxide (250 ppm) for 1 h. Total RNA was isolated, reverse transcribed, labeled and hybridized to oligonucleotide microarrays.
