A comparison of GS-5759, a bifunctional Î²2-adrenoceptor agonist and PDE4 inhibitor, and indacaterol and GSK 256066 in combination on gene expression changes in the BEAS-2B human airway epithelial cell line

ABSTRACT: GS-5759 is a bifunctional ligand composed of a quinolinone-containing pharmacophore found in several Î²2-adrenoceptor agonists linked covalently to a phosphodiesterase 4 inhibitor (PDE4) related to GSK 256066 by a pent-1-yn-1-ylbenzene spacer. The object of the study was to detemine if gene expression changes induced by GS-5759 were replicated by a Î²2-adrenoceptor agonist (indacaterol; Ind) and a PDE4 inhibitor (GSK 256066; GSK) in combination. Microarray analysis was performed on RNA from BEAS-2B cells treated with GS-5759 and a combination of indacaterol and GSK 256066 to identify differentialy expressed genes. Confluent BEAS-2B cells were treated with vehicle, Ind/GSK or GS-5759 for 1h, 2h, 6h or 18h. Total RNA was extracted, quantified (NanoDrop 2000) and the quality of each sample determined by using the Agilent 2100 Lab-on-a-Chip system before being processed for gene expression chnages by Expression Analysis Inc (Dunham, NC, USA).

Transcription profiling of human bronchial epithelial cells to low doses of cigarette smoke condensate - chronic exposure

Project description:BEAS-2B cells have been treated with low doses (20 ug/ml) of CSC for 4 months. As negative control BEAS-2B cells were treated with DMSO (the CSC solvent). Non-treated cells were cultivated in parallel. Experiment Overall Design: After each month total RNA was extracted from three replicates of CSC, DMSO and non-treated BEAS-2B cells and hybridized to Affymetrix GeneChips.

Transcription profiling of human ronchial epithelial cells to low doses of cigarette smoke condensate and subsequent demethylation agent

Project description:The study seeks to identify the epigenetic changes caused by exposure of to cigarette smoke condensate. To this goal human bronchial epithelial cells, BEAS-2B, were treated with 5-aza-2âdeoxycitidine and trychostatin A (5AzaC/TSA) subsequent to a chronic exposure (1 month) to cigarette smoke condensate (CSC). As negative control served BEAS-2B cells that were untreated or treated with CSC/DMSO for one month without the subsequent application of 5Aza/TSA. Experiment Overall Design: BEAS-2B Cells were treated for one month with CSC, DMSO, and left untreated. Subsequently half of the samples were treated with the demethylation agent. So that there were six different conditions with three biological replicates each. One sample had to be excluded because of low quality.

Analysis of glucocorticoid receptor (NR3C1), NFkb (p65 subunit), and RNA polymerase 2 (RNAP2) binding in Beas-2B airway epithelial cells

Project description:The objective of this study was to determine binding patterns for GR, 65 and RNAP2 in Beas-2B airway epithelial cells after treatment with dexamethasone (100 nm), TNF (20 ng/ml) or both for one hour. This study utilized duplicate samples for each treatment condition and immunoprecipitation except for p65 immunoprcipitation of TNF treated samples, which was analyzed as a single sample. Input from vehicle treated cells was used a control. Experimental comparisons were made between the following samples/ treatment conditions. Duplicate samples of Beas-2B cells treated with ethanol (vehicle) were used for ChIP of GR, p65, and RNAP2 (2 samples each antibody). Duplicate samples of Beas-2B cells treated with dexamethasone were used for ChIP of GR and RNAP2 (2 samples each antibody). Duplicate samples of Beas-2B cells treated with TNF were used for ChIP of p65 and RNAP2 (1 sample p65, 2 samples RNAP2). Duplicate samples of Beas-2B cells treated with dexamethasone + TNF were used for ChIP of GR, p65 and RNAP2 (2 samples each antibody).

Expression data from human lung epithelial cells after amorphous silica nanoparticle exposure for 40 passages

Project description:Amorphous silica nanoparticles induce malignant transformation and tumorigenesis of human lung epithelial cells. We used microarrays to detail the global programme of gene expression underlying the cellular malignant transformation induced by amorphous silica nanoparticles and identified distinct classes of up-regulated and down-regulated genes during this process. The human lung epithelial cells, Beas-2B were continuously exposed to 5 Î¼g/mL amorphous silica nanoparticles for 40 passages, and named as BeasSiNPs-P40 (shortly as P40-5 during the further microarray detection). Meanwhile, the passage-matched control Beas-2B cells, named as Beas-P40 (shortly as NC during the further microarray detection).

Anti-influenza activity of succinate

Project description:In the present study, we discovered an unexpected interplay between immunometabolism and antiviral immunity. Profiling of human bronchial epithelial BEAS-2B cells was performed using Agilent’s SurePrint G3 human gene expression microarray kit. A single-color design provided two types of comparison: (i) IAV-infected versus mock-infected cells, and (ii) succinate-treated infected cells versus mock-infected cells.

Epigenetic Repogramming by an Environmental Carcinogen Through Chromatin Domain Disruption [ChIP-Seq]

Project description:Alterations in chromatin modifications, including DNA methylation and histone modification patterns, have been characterized under exposure of several environmental pollutants, including nickel. As with other carcinogenic metals, the mutagenic potential of nickel compounds is low and is not well correlated with its carcinogenic effects. Nickel exposure, however, is associated with alterations in chromatin modifications and related transcriptional programs, suggesting an alternative pathway whereby nickel exposure can lead to disease. To investigate the extent to which nickel exposure disrupts chromatin patterns, we profiled several histone modifications, including H3K4me3, H3K9ac, H3K27me3 and H3K9me2 as well as the insulator binding protein CTCF and the transcriptomes of control BEAS-2B cells and cells treated with nickel for 72 hours. Our results show significant alterations of the repressive histone modification H3K9me2 in nickel-exposed cells with spreading of H3K9me2 into new domains associated with gene silencing. We furthermore show that local regions of active chromatin can protect genes from nickel-induced H3K9me2 spreading. Interestingly, we show that nickel exposure selectively disrupts weaker CTCF sites, leading to spreading of H3K9me2 at these regions. These results have major implications in the understanding of how environmental carcinogens can affect chromatin dynamics and the consequences of chromatin domain disruption in disease progression. Treat BEAS-2B cells with NiCl2 for 72 hours and compare histone modification, CTCF binding to control BEAS-2B cells to see how they regulated gene expression by RNA-seq
