Project description:Every individual (W1-W4) was hybridised 4 times, including 2 dye swaps: W1: 23573-23576; W2: 23577-23580; W3: 23581-23584; W4: 23585-23588. Only 2 of 4 hybridisations wer made at the same preparation Keywords: parallel sample
Project description:To investigate the role of miRNAs in the progression of colon cancer, we performed comprehensive miRMA microarray analysis on RNA derived from colon cancer tissues and normal colon tissues. We identified a novel set of colon cancer-related miRNAs. Total RNA was isolated from colon cancer tissues and normal colon tissues. Six-condition experiment: H normal tiss vs. H tumor tissue, S normal tiss vs. S tumor tissue, W1 normal tiss vs. W1 tumor tissue, M normal tiss vs. M tumor tissue, W2 normal tiss vs. W2 tumor tissue, and Y normal tiss vs. Y tumor tissue. Biological replicates: 1H normal tiss, 1H tumor tissue, 1S normal tissM-oM-<M-^L1S tumor tissue, 1W1 normal tissM-oM-<M-^L1W1 tumor tissue, 1M normal tissM-oM-<M-^L1M tumor tissue, 1W2 normal tissM-oM-<M-^L1W2 tumor tissue, 1Y normal tiss and 1Y tumor tissue, independently grown and harvested. One replicate per array.
Project description:Our appreciation for the extent of Epstein Barr virus (EBV) transcriptome complexity continues to grow through findings of EBV encoded microRNAs, new long non-coding RNAs, and hundreds of new polyadenylated lytic transcripts. Here we report an additional layer to the EBV transcriptome through the identification of a repertoire of latent and lytic viral circRNAs. Utilizing RNase R-sequencing with cell models representing latency types I, II, and III, we identified circRNAs expressed from the latency Cp promoter involving backsplicing from the W1 and W2 exons to the C1 exon, from the EBNA BamHI U exon, and from the latency long-non-coding RPMS1 locus. We also identified circRNAs expressed during reactivation including an exon 8-to-2 backspliced LMP2 transcript and a highly expressed circRNA derived from the BHLF1 gene. Altogether we identified over 30 EBV circRNA candidates and validated and determined the structural features, expression profiles and nuclear-cytoplasmic distributions of several prominent viral circRNAs. Further, we show that two RPMS1 circRNAs are expressed in stomach cancer specimens. This study increases the known EBV latency and lytic transcriptome repertoires to include viral circRNAs and provides an essential foundation for investigations into the functions of this new class of EBV transcripts in EBV biology and disease.
