Project description:The data provide information expression profile in yeast for 5 different physioloigcal conditions during stress adpatation and stress recovery (normal growth, during stress adaptation, after stress adaptation, under stress recovery, after stress recovery) in yeast. The purpose of the study is to understand how histone acetyltransferase HATs (Gcn5) apply it is function in gene regulation by changing global or local histone acetylation level under different physiological conditions. Gene expression levels measured for at 5 different time points of physiological changes under stress adaptation and stress recovery.

Gcn5 enrichment, H3K18 and H4K16 acetylation level and Histone H3 density are mearured and compared to input signal for 5 different physioloigcal conditions (normal growth, during stress adaptation, after stress adaptation, under stress recovery, after stress recovery). Replicates are used.

Project description:Here we studied genome-wide localization of Gcn5 under normal and KCl stress conditions in both yeast species. We found that in Saccharomyces cerevisiae, the enrichment of Gcn5 on genes changes from a relatively even distribution between coding region and intergenic region in the absence of stress, to a predominant localization in gene coding regions under stress conditions. This altered pattern changes are at global level indicates an important role of Gcn5 in modifying chromatin structure for stress adaptation in S. cerevisiae. The altered pattern changes are not observed in Saccharomyces pombe suggesting the different regulatory mechinery between two yeast speices. The related data series is GSE5218, where we have compared the gene regulation of Gcn5 at expression level in S. cerevisiae and S. pombe.

Project description:We conducted a set of lab-evolution experiments in yeast and followed the long-term dynamics of aneuploidy under diverse conditions including heat shock and high PH. Each evolution experiment starts with an ancestor strain that was subjected (in several independent repetitions) to certain growth conditions such as high temperature 39°C, permissive temperature 30°C, gradually increasing temperature from 30°C to 39°C, high pH=8.6 and normal PH. In all cases the mRNA extraction was performed on a population sample that was grown for 18 generations under stress-less conditions. This is since we aimed to measure the gene expression changes that are due to stress adaptation and not the physiological response.

Project description:Adaptation to altered osmotic conditions is a fundamental property of living cells and has been studied in particular detail in the yeast Saccharomyces cerevisiae. Yeast cells accumulate glycerol as compatible solute, controlled at different levels by the High Osmolarity Glycerol (HOG) response pathway. Up to now, essentially all osmostress studies in yeast have been performed with glucose as carbon and energy source, which is metabolised by glycolysis with glycerol is as a normal by-product. Here we investigated the response of yeast to osmotic stress when yeast is respiring ethanol as carbon and energy source. Remarkably, yeast cells do not accumulate glycerol under these conditions and it appears that trehalose may partly take over the role as compatible solute. The HOG pathway is activated in very much the same way as in during growth on glucose medium and is also required for osmotic adaptation. Slower volume recovery was observed in ethanol-grown cells as compared to glucose-grown cells. Dependence on key regulators as well as the global gene expression profile were similar in many ways to those previously observed in glucose-grown cells. However, there are indications that cells re-arrange redox-metabolism when respiration is hampered under osmostress, a feature that could not be observed in glucose-grown cells.
