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

ABSTRACT: 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.

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).

high-throughput sequencing of circRNAs in T-BEAS-2B cells and C-BEAS-2B cells

Project description:We report the differential expression of circRNAs between T-BEAS-2B cells (cadmium-transformed BEAS-2B cells) and C-BEAS-2B cells (passage-matched control BEAS-2B cells) by high-throughput sequencing. T-BEAS-2B cells are BEAS-2B cells transformed by cadmium at 2.0 μM for twenty weeks, and C-BEAS-2B cells are their passage-matched control. RNAs were sequenced on Illumina HiSeq Xten platform in triplicates, and expressions of circRNAs were calculated by TPM (transcripts per kilobase of exon model per million mapped reads). Clean data per sample exceeds 10 GB. We find 235 significantly up-regulated circRNAs and 271 significantly down-regulated circRNAs in T-BEAS-2B cells relative to C-BEAS-2B cells. Our work provides clues and evidence for exploring the mechanism of circRNAs in cadmium carcinogenesis.

Expression data from BEAS-2B cells

Project description:BEAS-2B cells are human bronchial epithelial cells, and often used as a in vitro model for the detection of potential pulmonary toxicity of chemicals. We used microarrays to detail the global programme of gene expression underlying cellularisation and identified distinct classes of up-regulated genes after treated with chemical substance
