Project description:Expression profile of Schizosaccharomyces pombe genome in asf1-1 and ∆hip1 cells. Expression profile of mutant cells compared to wild-type cells. Agilent 60mer oligonucleotide custom array containing probes spanning large portion of chromosome 2 at 50bp resolution was used to profile expression levels in mutant cells and to compare them to levels in wild-type cells.

Cellular quiescence is dependent upon the HIRA histone chaperone

Project description:Quiescence (G0) is a reversible non-dividing state that facilitates cellular survival in adverse conditions. Here we demonstrate that the function of the HIRA histone chaperone complex is required for viability during nitrogen-starvation induced quiescence in Schizosaccharomyces pombe. G0 cells lacking the HIRA protein, Hip1 exhibit elevated levels of antisense ncRNAs and an increase in unrepaired DNA double strand breaks. Nitrogen-starved hip1∆ cells retain metabolic activity but, in contrast to wild type, rapidly lose the ability to resume proliferation. After a short period in G0 (1 day), hip1∆ mutants are able to resume cell growth in response to the restoration of a nitrogen source, but do not efficiently induce Start-specific gene expression and re-enter the cell cycle. However, hip1∆ cells rapidly progress to an unresponsive state and by 4 days in G0, the majority no longer initiate growth following nitrogen source restoration. Analysis using a conditional hip1 allele is consistent with these findings and indicates that HIRA is required for efficient exit from quiescence and prevents a permanent cell cycle arrest.

Histone H4 acetylation in wild-type, ASF1, SET2 and ASF1 SET2 deletion yeast strains

Project description:ChIP-on chip assays to measure the change in histone acetylation over the yeast genome, in ASF1, SET2 and ASF1 SET2 deletion yeast strains compared to the wild-type control. ChIPs of AcH4 from wild-type, ASF1, SET2 and ASF1 SET2 deletion yeast strains were normalized to the H3 enrichment.
