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.

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

Project description:As environmental pollutants and possible carcinogens, carbon nanotubes (CNTs) have recently been found to promote tumorigenesis and tumor metastasis after long-term pulmonary exposure. However, whether CNT-induced carcinogenesis can be inherited and last for generations remains unknown. Here, we establish a post-chronic single-walled carbon nanotubes (SWCNTs) exposed human bronchial epithelium BEAS-2B cell model to investigate SWCNTs-induced carcinogenesis. At a tolerated sublethal dose level, post-chronic SWCNTs exposure significantly increases the migration and colony formation abilities of BEAS-2B cells, leading to cell malignant transformation. Notably, the malignant transformation of BEAS-2B cells is irreversible within 60 days recovery period after SWCNTs exposure, and the malignant transformation activities of cells gradually increase during the recovery period. Mechanism analyses show that post-chronic exposure to SWCNTs causes substantial DNA methylation and transcriptome dysregulation of BEAS-2B cells. Subsequent enrichment and clinical database analyses reveal that differentially expressed/methylated genes of BEAS-2B cells are enriched in cancer-related biological pathways, and several of these genes are validated in lung cancer patients.

Project description:These data suggest that co-culture with macrophages increases expression of NDRG-1 in epithelial cell lines. The finding is confirmed in 1 mouse epithelial cell line, and in tissue derived from mice genetically and dietetically altered to increase macrophage infiltration of the small and large intestinal epithelium. NDRG1 is identified as a potential mediator of macrophage effects on tumorigenesis in the large and small intestine. Array data is part of a larger study involving the effects of Vitamin D, in concert with macrophages, on intestinal homeostasis and tumorigenesis, entitled Cell autonomous and non-autonomous interactions of a western-style diet and the vitamin D receptor in intestinal homeostasis and tumorigenesis Cells from human colon cancer cell lines were cultured either alone, with Vitamin D3, with THP1 macrophages, or with THP1 macrophages and Vitamin D3, in a system which allowed no physical contact but exchange of soluble factors between the cell types.

Project description:Human non-transformed lung epithelial cell line (BEAS-2B) was transduced with a control (BEAS-C) or PI3KCA-E545K (BEAS-PI3K-CA) expressing lentivirus. After clones selection, RNA was extracted from three different clones for each cell line. For mRNA expression profiling, 500 ng total RNA were reverse transcribed and used for synthesis of cDNA and biotinylated cRNA. Finally cRNA were hybridized for 18 hours on Illumina HumanHT-12 v3.0 BeadChips and after scanning, data analysis was performed.

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 The control cells were the human non-transformed BEAS-2B cells (Lechner JF, LaVeck MA. A serum-free method for culturing normal human bronchial epithelial cells at clonal density. J. Tissue Culture Methods 9: 43-48, 1985). The BEAStra1 and BEAStra2 cells were replicate populations of BEAS-2B cells that were transformed following infection with mycoplasma (Jiang, S., Zhang, S., Langenfeld, J., Lo, S.C., and Rogers, M.B., Mycoplasma infection transforms normal lung cells and induces bone morphogenetic protein 2 expression by post-transcriptional mechanisms. J Cell Biochem. 104(2): 580-594, 2007). A459 lung adenocarcinoma cells were derived from a human lung tumor (Giard DJ, et al. In vitro cultivation of human tumors: establishment of cell lines derived from a series of solid tumors. J. Natl. Cancer Inst. 51: 1417-1423, 1973. PubMed: 4357758).
