ABSTRACT: Transcriptome profiling of yeast strains responding to 0.7M NaCl treatment for 30 or 60 minutes. This study identified affected genes under both conditions tested. Transcript and protein changes were compared to determine mRNAs contribution to protein levels during salt acclimation. Two-color fluorescence arrays reporting on mRNA abunance in strains before and at 30 min or 60 min after a shock with 0.7M NaCl, hybridized to yeast tile-genome Nimblegen arrays
Project description:Transcriptome profiling of yeast mutant strains responding to 0.7M NaCl treatment for 30 minutes. This study identified affected genes in each mutant and used it to computationally infer the complete NaCl-activated signaling network in yeast. Two-color fluorescence arrays reporting on mRNA abundance in strains before and at 30 min after a shock with 0.7M NaCl, hybridized to yeast tile-genome Nimblegen arrays
Project description:Transctriptome profiling of CTD-14 repeats, 2A, 5A mutants responding to 0.7N NaCl for 30mins. The study shows that phosphorylation at Ser5 sites plays a role in normal induction and repression of genes upon NaCl stress. The CTD14 strains harbors a plasmid expressing RPB1 with 14 wild-type CTD repeats. 5A strains carries a plasmid expressing a chimeric RPB1 in which the CTD was composed of 5 repeats of CTD-serine 5 substituted with Ala followed by 7 wild-type-sequenced repeats. The 2A strains carrys 8 repeats of CTD-serine 2 substituted with alanine followed by 7 wild-type-sequenced repeats.

Project description:Microarray timecourses followed the gene expression response of Saccharomyces cereviciae to osmotic shock, over 4 hours. Data was compared to timecourses of quantitative proteomic data to understand the dynamic relationship between RNA and protein The dynamic genomic expression response to osmotic shock (0.7M NaCl) was measured in Saccharomyces cereviciae, over the course of 4 hours in biological triplicate. Six timepoints were taken for each time course, for a total of 18 tiled-genomic Nimblegen arrays against the S288c yeast genome.
Project description:BY4741 (S288c haploid) cells have different gene expression in response to 0.4mM H2O2 when pretreated with 0.7M NaCl compared to cells that are not pretreated with NaCl (mock cells). Cells lacking Nup42p do not exhibit a different gene expression in response to H2O2 between naive cells and cells pretreated with 0.7M NaCl
Project description:Samples GSM206658-GSM206693: Acquired Stress resistance in S. cerevisiae: NaCl primary and H2O2 secondary Transcriptional timecourses of yeast cells exposed to 0.7M NaCl alone, 0.5mM H2O2 alone, or 0.5mM H2O2 following 0.7M NaCl, all compared to an unstressed sample. Repeated using msn2∆ strain. Samples GSM291156-GSM291196: Transcriptional response to stress in strains lacking MSN2 and/or MSN4 Transcriptional timecourses of yeast cells (WT, msn2∆, msn4∆, or msn2∆msn4∆) exposed to 0.7M NaCl for 45 minutes or 30-37˚C Heat Shift for 15 min compared to an unstressed sample of the same strain.

Project description:A series of experiments comparing the gene expression response before and after 30 min 0.7M NaCl exposure in WT and mutant yeast strains. Mutant strains were identified as having a defect in acquiring resistance to H2O2 following mild NaCl pretreatment. The mutants in this study were taken from the Yeast Knock-Out Collection, mat a. Unstressed cells vs cells exposed to 0.7M NaCl for 30 min; 5 replicates for WT, 3 replicates for hog1∆, msn2∆, mck1∆, pde2∆, rim101∆, and 2 replicates for the remaining mutants.

Project description:The modification of Ser 5 is important for the relocalization of RNAP II upon NaCl stress. The CTD14 strains harbors a plasmid expressing RPB1 with 14 wild-type CTD repeats. The 5A strain carries a plasmid expressing a chimeric RPB1 in which the CTD was composed of 5 repeats of CTD-serine 5 substituted with alanine followed by 7 wild-type-sequenced repeats.
