Genome-wide analysis of wild type and gemin2 mutant plants [cold exposure]

ABSTRACT: The goal of this study was to compare the transcriptional profile (RNA-seq) of wild type and gemin2 Arabidopsis mutants plants exposed to 10ºC for 0, 1 and 24 hours. WT and gemin2 mutant plants were grown for nine days under continuous white light at 22 degrees centigrades or exposed for 1 or 24 h to 10ºC on the 9th day, before harvesting. Then the transcriptional profile of these plants was analyzed using RNA-seq.

The mechanisms by which poikilothermic organisms ensure that biological processes are robust to temperature changes are largely unknown. Temperature compensation, the ability of circadian rhythms to maintain a relatively constant period over the broad range of temperatures resulting from seasonal fluctuations in environmental conditions, is a defining property of circadian networks. Temperature affects the alternative splicing (AS) of several clock genes in fungi, plants, and flies, but the spli ...[more]

Genome-wide analysis of Dengue virus 2 infected cells

Project description:The goal of this study was to compare the transcriptional profile (RNA-seq) of Dengue virus 2 and mock infected cells at 24 and 36 hours post infection. Dengue virus NS5 protein plays multiple functions in the cytoplasm of infected cells, enabling viral RNA replication and counteracting host antiviral responses. Here, we demonstrate a novel function of NS5 in the nucleus where it interferes with cellular splicing. Using global proteomic analysis of infected cells together with functional studies, we found that NS5 binds spliceosome complexes and modulates endogenous splicing. In particular, we show that NS5 alone, or in the context of viral infection, interacts with core components of the U5 snRNP particle, CD2BP2 and DDX23, alters the inclusion/exclusion ratio of alternative splicing events, and changes mRNA isoform abundance of known antiviral factors. Interestingly, a genome wide transcriptome analysis, using recently developed bioinformatics tools, revealed an increase of intron retention upon dengue virus infection, and viral replication was improved by silencing specific U5 components. Different mechanistic studies indicate that binding of NS5 to the spliceosome reduces the efficiency of pre-mRNA processing, independently of NS5 enzymatic activities. We propose that NS5 binding to U5 snRNP proteins hijacks the splicing machinery resulting in a less restrictive environment for viral replication. A549 cells where infected with Dengue virus 2 or mock and after 24 and 36 hours post infection mRNA was purified. Then the transcriptional profile of these cells was analyzed using RNA-seq.

HSF1 drives a transcriptional program distinct from heat shock to support highly malignant human cancers [ChIP-Seq]

Project description:Heat-Shock Factor 1 (HSF1), master regulator of the heat-shock response, facilitates malignant transformation, cancer cell survival and proliferation in model systems. The common assumption is that these effects are mediated through regulation of heat-shock protein (HSP) expression. However, the transcriptional network that HSF1 coordinates directly in malignancy and its relationship to the heat-shock response have never been defined. By comparing cells with high and low malignant potential alongside their non-transformed counterparts, we identify an HSF1-regulated transcriptional program specific to highly malignant cells and distinct from heat shock. Cancer-specific genes in this program support oncogenic processes: cell-cycle regulation, signaling, metabolism, adhesion and translation. HSP genes are integral to this program, however, even these genes are uniquely regulated in malignancy. This HSF1 cancer program is active in breast, colon and lung tumors isolated directly from human patients and is strongly associated with metastasis and death. Thus, HSF1 rewires the transcriptome in tumorigenesis, with prognostic and therapeutic implications. ChIP-seq was used to characterize HSF1 binding

Tight coordination of protein translation and heat shock factor 1 activation supports the anabolic malignant state [ChIP-Seq]

Project description:A unifying characteristic of aggressive cancers is a profound anabolic shift in metabolism to enable sustained proliferation and biomass expansion. The ribosome is centrally situated to sense metabolic states but whether it impacts systems that promote cellular survival is unknown. Here, through integrated chemical-genetic analyses, we find that a dominant transcriptional effect of blocking protein translation in cancer cells is complete inactivation of heat shock factor 1 (HSF1), a multifaceted transcriptional regulator of the heat-shock response and many other cellular processes essential for tumorigenesis. Translational flux through the ribosome reshapes the transcriptional landscape and links the fundamental anabolic processes of protein production and energy metabolism with HSF1 activity. Targeting this link deprives cancer cells of their energy and chaperone armamentarium thereby rendering the malignant phenotype unsustainable. We used ChIP-Seq to examine affect of rocaglates and cycloheximide on HSF1 genomic occupancy in MCF7 and M0-91 cancer cells.

Control of Embryonic Stem Cell State by Mediator and Cohesin (Illumina ChIP-Seq data)

Project description:The key transcription factors that control the embryonic stem cell gene expression program have been identified, but how they function to implement this program is not well understood. While screening for genes essential for maintenance of ES cell state, we identified many components of the Mediator and Cohesin complexes. Mediator and Cohesin were found to physically and functionally connect the enhancers and core promoters of active genes. An ES cell Mediator complex was found to copurify with Cohesin and its loading factor Nipbl, and normal levels of these proteins were essential for expression of the genes they occupy and for maintenance of ES cell state. See associated publication.

Derivation of pre-X inactivation human embryonic stem cells under physiological oxygen concentrations

Project description:The presence of two active X chromosomes (XaXa) is a hallmark of the ground state of pluripotency specific to murine embryonic stem cells (ESCs). Human ESCs invariably exhibit signs of X chromosome inactivation (XCI) and are considered developmentally more advanced than their murine counterparts. We describe the establishment of the first XaXa hESCs derived under physiological oxygen concentrations. Using these cell lines we demonstrate that (1) differentiation of hESCs induces random XCI in a manner similar to murine ESCs, (2) chronic exposure to atmospheric oxygen is sufficient to induce irreversible XCI with minor changes of the transcriptome, (3) the Xa exhibits heavy methylation of the XIST promoter region, and (4) XCI is associated with demethylation and transcriptional activation of XIST along with H3K27-me3 deposition across the Xi. These findings indicate that the human blastocyst contains pre-X-inactivation cells and that this state is preserved in vitro through culture under physiological oxygen. Examination of 2 different histone modifications (H3K4me3 and H3K27me3) in 3 ES cell lines in 5% and 20% oxygen.

Promoter proximal pausing and its regulation by c-Myc in embryonic stem cells: ChIP-Seq

Project description:Recruitment of the RNA Polymerase II (Pol II) transcription initiation apparatus to promoters by specific DNA binding transcription factors is well recognized as a key regulatory step in gene expression. We describe here evidence that promoter-proximal pausing is a general feature of transcription by Pol II in embryonic stem (ES) cells, and thus an additional step where regulation of gene expression may occur. We report here that c-Myc, which occupies a third of actively transcribed genes in ES cells and is a key regulator of cellular proliferation, binds P-TEFb and contributes to release of promoter-proximal paused Pol II at these genes. ChIP-seq data for Pol II and additional factors controlling pause release in mouse ES cells.

Chromatin Structure and Gene Expression Programs of Human Embryonic and Induced Pluripotent Stem Cells (ChIP-seq)

Project description:Knowledge of both the global chromatin structure and the gene expression programs of human embryonic stem (ES) cells and induced pluripotent stem (iPS) cells should provide a robust means to assess whether the genomes of these cells have similar pluripotent states. Recent studies have suggested that ES and iPS cells represent different pluripotent states with substantially different gene expression profiles. We describe here a comparison of global chromatin structure and gene expression data for a panel of human ES and iPS cells. Genome-wide maps of nucleosomes with histone H3K4me3 and H3K27me3 modifications indicate that there is little difference between ES and iPS cells with respect to these marks. Gene expression profiles confirm that the transcriptional programs of ES and iPS cells show very few consistent differences. Although some variation in chromatin structure and gene expression was observed in these cell lines, these variations did not serve to distinguish ES from iPS cells. Examination of two histone modifications (H3K4me3 and H3K27me3) in 6 human ES cell lines, 8 human iPS cell lines, and 1 fibroblast cell line.
