Project description:The SSG1-1 mutation was an allele of the YHR032W gene in Saccharomyces cerevisiae. The SSG1-1 mutants contained higher levels of AdoMet than wild type (WT). SSG1-1 single mutants were shown to have a long lifespan, suggesting that the Ssg1-1 protein might have a role in longevity. We used microarrays to compare the global gene expression profiles between the wild type and SSG1-1 mutants under normal growth condition.
Project description:Contains a collection of wildtype Saccharomyces cerevisiae strains for estimating the biological variation. Wildtypes are obtained from the yeast wildtypes – platereader, wt pool background set HybSet, by randomly taking 100 wt vs. refpool (pooled wts) and 100 refpool vs. wt hybridizations

Project description:Investigation of whole genome gene expression level changes in three S. cerevisiae Y55 mutants, compared to the wild-type strain. The UV-induced mutations enable the mutant strains to ferment high-gravity maltose faster than the WT. The mutants analyzed in this study are further described in Baerends, R.J.S., J.L. Qiu, L. Gautier, and A. Brandt. A high-throughput system for screening of fast-fermenting Saccharomyces cerevisiae strains. Manuscript in preparation.
Project description:In our previous work, we had found that Saccharomyces cerevisiae needs of the Hog1 and Slt2 proteins to growth in a low pH environment caused by sulfuric acid, one of the stress factors during the process of ethanol production. Then was performed the gene-wide expression analysis in the hog1∆ and slt2∆ mutants in order to reveal the function of the Hog1p and Slt2p MAP Kinases in the regulation of S. cerevisiae global gene expression upon stress by sulfuric acid.
Project description:Expression profiles of 110 the central metabolism-related enzymes were obtained by the selected reaction monitoring (SRM) assay methods using LC-MS/MS from the wild type (BY4742), a GCR2 gene deletion strain, and 29 single-gene deletion strains lacking enzyme genes responsible for central carbon metabolism (including CIT1, ENO1, FBP1, GCR2, GND1, GPD1, GPM2, HOR2, HXK1, HXK2, IDH1, IDH2, IDP1, LPD1, MAE1, MDH1, MDH2, PDA1, PDC1, PFK1, PYC2, RPE1, TAL1, TDH1, TDH2, TDH3, TKL1, TPS1, TPS2, and ZWF1 genes).
The central carbon metabolism is strictly controlled by modulation of enzyme expressions to maintain an essential system of living organisms. In this study, metabolic safety mechanisms in the model organism, Saccharomyces cerevisiae, were investigated by direct determination of enzyme expression levels. Targeted proteome analysis of 31 S. cerevisiae wild type and mutant strains revealed that at least 30% of the observed variations in enzyme expression levels could be explained by global regulatory mechanisms. Co-expression analysis revealed that expression levels of enzymes involved in trehalose metabolism and glycolysis changed in a coordinated manner under the control of the transcription factors for global regulation.
Project description:Study of the response to the osmotic shock and its effect on gene expression regulation in different strains of Saccharomyces cerevisiae (WT and Sln1/Ypd1 mutants). The cells received a sodium chloride stimulation (NaCl 0.4M), and were sampled at the time of stimulation (0 min) and in 10 and 20 minutes after the stimulation.
Project description:Expression analysis of Saccharomyces cerevisiae TAF5 and taf5 temperature conditional mutants grown at permissive and non-permissive temperature. Investigation of whole genome gene expression level changes in Saccharomyces cerevisae taf5-17, taf5-45, taf5-408 and taf5-10.4 mutants, compared to the wild-type strain. The mutations engineered into the strains confer temperature conditional growth. The mutants analyzed in this study are further described in Layer et. al., 2010.
