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
