View SamplesThis study addresses long-term effects of clinically relevant regimens of radiation in human glioma stem cells. Our investigations reveal a strikingly diverse spectrum of changes in cell behavior, gene expression patterns and tumor-propagating capacities evoked by radiation in different types of glioma stem cells. Evidence is provided that degree of cellular plasticity but not the propensity to self-renew is an important factor influencing radiation-induced changes in the tumor-propagating capacity of glioma stem cells. Gene expression analyses indicate that paralell transcriptomic responses to radiation underlie similarity of clinically relevant cellular outcomes such as the ability to promote tumor growth after radiation. Our findings underscore the importance of longitudinal characterizations of molecular and cellular responses evoked by cytotoxic treatrments in glioma stem cells.

Treatment
View SamplesTo investigate the transcriptional remodelling during EMT, we treated normal murine mammary gland epithelial cells with TGFbeta for 0, 2h, 6h, 12h, 24h, 36h, 48h, 60h, 72h, 96h, 168h and 240h. Using WGCNA and pathway enrichment analysis we identified multiple gene expression modules that were enriched in general, signaling, metabolic or stuctural pathways highly relevant for EMT. Overall design: RNA sequencing of NMuMG/E9 cells induced to undergo EMT by treatment with TGFbeta from 0-10 days.

View SamplesPolycomb repressive complex 2 (PRC2) catalyzes histone H3K27me3, which characterizes many silenced genes including those on the inactive X-chromosome. Here we interrogate the role of core PRC2 protein EED in X-linked gene silencing by assessing allele-specific X-linked gene expression in WT and Eed-/- hybrid mouse trophoblast stem cells (TSCs) harboring a 129/S1-derived maternal X-chromosome and a JF1/Ms-derived paternal X-chromosome. This study generates mRNA-seq data for WT and Eed-/- TSCs, which undergo imprinted inactivation of the paternal X-chromosome. RNA-seq data was mapped allele-specifically to in silico strain-specific maternal and paternal reference genomes, generated based on known single nucleotide polymorphisms. We find that EED loss abrogates H3K27me3 and expression of Xist lncRNA, which is required for X-inactivation, however, despite the absence of H3K27me3 and Xist, only a subset of PRC2 target genes are derepressed in Eed-/- TSCs. Overall design: RNA-seq profiles of four WT (Eed +/+ and Eed fl/fl) and three EED null (Eed -/-) female TS cell lines were generated through strand-specific 100 bp paired-end sequencing on the Illumina HiSeq2000

View SamplesThe cumulus cells niche that surrounds the oocyte is essential for its maturation and presumably for the oocyte to acquire its competence to confer pluripotency. The cells cultured from the human oocyte cumulus niche (hCC) could be used as feeders for the propagation of human pluripotent stem cells in vitro.

View SamplesWe investigated the effect of miR-1199-5p, miR-200b-3p and miR-429-3p on gene expression profiles during TGFbeta-induced EMT in normal murine mammary gland cells by using the mRNA-sequencing. Our analysis demonstrates that miR-1199-5p and both miR-200 family members share only 6 target genes, indicating that besides regulating Zeb1 expression they exert distinct functions during EMT. Overall design: mRNA profiles of NMuMG cells transiently overexpressing miR-1199-5p, miR-200b-3p or miR-429-3p and treated with TGFbeta for 4 days

View SamplesFunctional and structural dysfunction of the blood brain barrier (BBB) leads to severe alterations in brain physiology and is believed to trigger neurodegeneration. To investigate the molecular mechanisms driving the BBB dysfunction, very few human BBB cell culture models are available; of which, the human microvascular endothelial cell line (hCMEC/D3) is the most widely used. Thus far, array-based approaches or targeted seqeuncing based approaches have been employed to characterize the gene expression of the hCMEC/D3 model. However,The goal of this study is to perform deep transcriptomic sequencing of the BBB cell line and obtain features like gene expression, expressed single nucleotide variants, alternate splice forms, circular RNAs, long non-coding RNAs and micro RNAs. Overall design: We have developed blood brain barriers transcriptomics landscape using RNA sequencing and micro RNA seqeuncing data obtained from replicates of hCMEC/D3 BBB cell line.
