Comparison of gene expression profiles in chromate transformed BEAS-2B cells

ABSTRACT: We established chromate transformed cell lines by chronic exposure of normal human bronchial epithelial BEAS-2B cells to low doses of hexavalent chromium followed by anchorage-independent growth. The gene expression profiles were analyzed in the established cell lines. The gene expression profiles from six chromate transformed cell lines were remarkably similar to each other yet differed significantly from that of either control cell line or normal Beas-2B cells. A total of 409 differentially expressed genes were identified in chromate transformed cells compared to control cells.

Comparison of gene expression profiles in chromate transformed BEAS-2B cells

The gene expression profiles were analyzed in the established cell lines. The gene expression profiles from six chromate transformed cell lines were remarkably similar to each other yet differed significantly from that of either control cell line or normal Beas-2B cells. A total of 409 differentially expressed genes were identified in chromate transformed cells compared to control cells. We analyzed gene expression profiles from 10 cell lines ( six chromated transformed cells lines, three control cell lines, and parental BEAS-2B cells) using Affymetrix Human Gene 1.0 ST array. No techinical replicates were performed.

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.

Effect of depletion of Fer on gene expression of BEAS-2B cells

Project description:To investigate the function Fer in the tumorigenesis, we established BEAS-2B cell lines in which Fer has been knocked down by shRNA. We then performed gene expression profiling analysis using data obtained from RNA-seq of 2 different cells.

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

MicroRNA levels in non-transformed and transformed lung cells

Project description:MicroRNA levels in non-transformed BEAS-2B bronchial epithelial cells, two lines of mycoplasma transformed BEAS-2B cells, and A549 lung adenocarcinoma cells were measured. Microarray analyses of 1145 microRNAs in A549 lung adenocarcinoma cells and two other transformed lung cell types relative to BEAS-2B bronchial epithelial cells were performed. 106 miRNAs were down-regulated and 69 miRNAs were up-regulated in all three transformed lines
