Project description:Metabolomics data from E. Coli Nissle (wild type, WT) and 3 E. Coli Nissle knockout (KO) strains grown in M-9 media and enriched M-9 media.
Project description:Yeast lacking the H3 or H4 amino termini, and corresponding wild type strains, were grown in synthetic media. These conditions induce Gcn4-activated transcription. Keywords: Genetic modification
Project description:This experiment investigates yeast pathways involved in the secretion of metabolites that enable the growth of lactic acid bacteria. Wild-type Saccharomyces cerevisiae (S90) in different defined media, as well as four mutant yeasts with selective gene deletions, were forwarded to RNA-seq to characterise global differences in transcriptomes and identify genes/pathways with altered gene expression levels.
Project description:An updated representation of S. meliloti metabolism that was manually-curated and encompasses information from 240 literature sources, which includes transposon-sequencing (Tn-seq) data and Phenotype MicroArray data for wild-type and mutant strains.
Project description:RNA-seq was performed on T. maritima wild type, three glucose evolved cultures, and three glycerol adapted cultures. Wild type and glucose evolved strains were grown on glucose minimal media and glycerol evolved cultures were grown on glycerol minimal media. All samples were harvested in exponential phase.
Project description:These microarray studies are part of a larger study characterizing a deletion mutant of the putative transcriptional regulator IclR in Francisella tularensis LVS and SchuS4 strains. The microarrays were performed using RNA isolated from wild-type LVS and a LVS iclR deletion mutant after growing in Chamberlain?s defined media pH 6.3 to early mid-log phase. Results suggest that IclR affects expression of several genes after determining statistically significant differences by SAM.
Project description:<p>Gene expression is a biological process regulated at different molecular levels, including chromatin accessibility, transcription, and RNA maturation and transport. In addition, these regulatory mechanisms have strong links with cellular metabolism. Here we present a multi-omics dataset that captures different aspects of this multi-layered process in yeast. We obtained RNA-seq, metabolomics, and H4K12Ac ChIP-seq data for wild-type and mip6delta strains during a heat-shock time course. Mip6 is an RNA-binding protein that contributes to RNA export during environmental stress and is informative of the contribution of post-transcriptional regulation to control cellular adaptations to environmental changes. The experiment was performed in quadruplicate, and the different omics measurements were obtained from the same biological samples, which facilitates the integration and analysis of data using covariance-based methods. We validate our dataset by showing that ChIP-seq, RNA-seq and metabolomics signals recapitulate existing knowledge about the response of ribosomal genes and the contribution of trehalose metabolism to heat stress.</p>

Project description:To rule out expression changes caused by depletion from, or excretion into the media, wild-type yeast was transferred to filtered media in which slow-growing deletion strains were grown previously
