Transcription profiling of S. cerevisiae H2A4-20 mutants vs. wild types

ABSTRACT: Total RNA from three replicate cultures of wild-type and mutant strains was isolated and the expression profiles were determined using Affymetrix arrays. Comparisons between the sample groups allow the identification of genes regulated by histone H2A^4-20 mutant. Experiment Overall Design: Comparison of genes whose mRNA levels are affected in a histone H2A^4-20 mutant yeast strain compared to wild-type yeast strain.

Regulation of gene transcription by the histone H2A N-terminal domain.

Parra Michael A MA Wyrick John J JJ

Molecular and cellular biology 20070827 21

Histone N-terminal domains play critical roles in regulating chromatin structure and gene transcription. Relatively little is known, however, about the role of the histone H2A N-terminal domain in transcription regulation. We have used DNA microarrays to characterize the changes in genome-wide expression caused by mutations in the N-terminal domain of histone H2A. Our results indicate that the N-terminal domain of histone H2A functions primarily to repress the transcription of a large subset of ...[more]

Expression data from Saccharomyces cerevisiae histone H2A mutants

Project description:The N-terminal tail of histone H2A shows evolutionary changes that parallel genome size and aid chromatin compaction. As genome size increases, so does the number of arginines. In contrast, serines corellate with small genomes. Examples for such changes are arginine in position 11 and serine in position 15. To test if these residues affect mRNA levels, we analysed gene expression profiles of S.cerevisiae strains containing either WT or mutant H2A. Yeast strains have endogenous histone H2A genes deleted and express plasmid born WT or mutant H2A. PolyA RNA of these strains was analyzed by single channel microarray hybridization. Three WT biological replicates provide the control. Two biological replicates of each of the mutants containing either R11, K11, carrying a deletion in S15 and the double mutant carrying both the deletion of S15 and an insertion of R11 are analysed.

INO80 promotes reassembly of promoter proximal nucleosomes.

Project description:INO80 and SWR1 mediate the exchange of H2A.Z and H2A. The influence of H2A.Z on overall gene expression in yeast is limited. Here we analyzed the possible influence on stress induced transcription, which changes expression of a large proportion of all yeast genes. Yeast cells (wild type and htz1 mutant) were grown to exponential phase and treated with osmotic stress (0.4M NaCl) for 20 minutes or left untreated. Experiments were performed with 2 biological replicates.
