GEO DataSets

(Submitter supplied) Genome-scale datasets have been used extensively in model organisms to screen for specific candidates or to predict functions for uncharacterized genes. However, despite the availability of extensive knowledge in model organisms, the planning of genome-scale experiments in poorly studied species is still based on the intuition of experts or heuristic trials. We propose that computational and systematic approaches can be applied to drive the experiment planning process in poorly studied species based on available data and knowledge in closely related model organisms. more...

(Submitter supplied) The packaging of DNA into nucleosomes influences the accessibility of underlying regulatory information. Nucleosome occupancy and positioning are best characterized in the budding yeast Saccharomyces cerevisiae, albeit in asynchronous cell populations or on individual promoters such as PHO5 and GAL1–10. Using FAIRE (formaldehyde-assisted isolation of regulatory elements) and whole-genome microarrays, we examined changes in nucleosome occupancy throughout the mitotic cell cycle in synchronized populations of S. more...

(Submitter supplied) Experiments performed over the past three decades have shown that nucleosomes are transcriptional repressors. In Saccharomyces cerevisiae, depletion of histone H4 results in the genome-wide transcriptional de-repression of hundreds genes. The mechanism of de-repression is hypothesized to be rooted directly in chromatin changes. To test this, we reproduced classical H4 depletion experiments by conditional repression of all histone H3 transcription, which depletes the supply of nucleosomes in vivo. more...

(Submitter supplied) We describe the genome-wide nucleosome profiles of four related yeast species. All species display the same global organization features first described in S. cerevisiae: a stereotypical nucleosome organization along genes, and the classification of promoters into these which contain or lack a pronounced Nucleosome Depleted region (NDR), with the latter displaying a more dynamic pattern of gene expression. more...

(Submitter supplied) A fundamental problem in biology is the molecular basis for divergence among related organisms. We have investigated the level of divergence of transcription factor binding sites for two key factors that regulate developmental processes in the budding yeasts. The genomic binding locations for the Ste12 and Tec1 transcription factors in S. cerevisiae, S. mikatae and S. bayanus were mapped by chromatin immunoprecipitation combined with microarrays (chIP chip)1, 2 and compared to one another. more...

(Submitter supplied) The chromatin architecture of eukaryotic gene promoters is generally characterized by a nucleosome-free region (NFR) flanked by at least one H2A.Z variant nucleosome. Computational predictions of nucleosome positions based on thermodynamic properties of DNA-histone interactions have met with limited success. Here we show that the action of the essential RSC remodeling complex in S. cerevisiae helps explain the discrepancy between theory and experiment. more...

(Submitter supplied) Transcriptional regulation of the Saccharomyces cerevisiae HO gene is highly complex, requiring a balance of multiple activating and repressing factors to ensure that only a few transcripts are produced in mother cells within a narrow window of the cell cycle. Here, we show that the Ash1 repressor associates with two DNA sequences that are usually concealed within nucleosomes in the HO promoter and recruits the Tup1 corepressor and the Rpd3 histone deacetylase, both of which are required for full repression in daughters. more...
