TranscriptomicsCell-cycle regulation of cohesin stability along fission yeast chromosomes
Sister chromatid cohesion is mediated by cohesin but the process of cohesion establishment during S phase is still enigmatic. Recent data indicate that in mammalian cells, cohesin binding to chromatin is dynamic in G1 but becomes stabilized during S phase. Whether the regulation of chromosomal cohes...

TranscriptomicsRNAi mediates post-transcriptional repression of gene expression in fission yeast Schizosaccharomyces pombe [Illumina Genome Analyzer]
RNA interference (RNAi) is a gene silencing mechanism conserved from fungi to mammals. Small interfering RNAs are products and mediators of the RNAi pathway and act as specificity factors in recruiting effector complexes. The Schizosaccharomyces pombe genome encodes one of each of the core RNAi prot...

TranscriptomicsFactors that promote H3 chromatin integrity during transcription prevent promiscuous deposition of CENP-A(Cnp1) in fission yeast
Specialized chromatin containing CENP-A nucleosomes instead of H3 nucleosomes is found at all centromeres. However, the mechanisms that specify the locations at which CENP-A chromatin is assembled remain elusive in organisms with regional, epigenetically regulated centromeres. It is known that norma...

TranscriptomicsTelomeric repeats facilitate CENP-A incorporation via telomere binding proteins
The histone H3 variant, CENP-ACnp1, is normally assembled upon canonical centromeric sequences, but there is no apparent obligate coupling of sequence and assembly, suggesting that centromere location can be epigenetically determined. To explore the tolerances and constraints on CENP-ACnp1 depositio...

TranscriptomicsDeletion of Clr3 restores expression of a subset of genes in gcn5- mutant cells
Histone acetylation and deacetylation is important for gene regulation. The histone acetyltransferase, Gcn5, is a known activator of transcriptional initiation that is recruited to gene promoters. Here we map genome-wide levels of Gcn5 occupancy and histone H3K14ac at high resolution. Gcn5 is predom...

TranscriptomicsGenome-wide studies of histone Me2 SWIRM and polyamine oxidase domain homologues of mammalian LSD1
In order to gain a more global view of the activity of histone demethylases we report here studies of the two fission yeast SWIRM and polyamine oxidase domain homologues of mammalian LSD1. Consistent with previous work (Nicolas et al., 2006) we find that the two S. pombe proteins, which we name Swm...

TranscriptomicsCentromeric H2B monoubiquitination promotes noncoding transcription and chromatin integrity
Functional centromeres are essential for proper cell division. Centromeres are established largely by epigenetic processes resulting in incorporation of the histone H3 variant CENP-A. Here, we demonstrate the direct involvement of H2B monoubiquitination, mediated by RNF20 in humans or Brl1 in Schizo...

TranscriptomicsDNA topoisomerase III localizes to centromeres and affects centromeric CENP-A levels in fission yeast
Centromeres are specialized chromatin regions marked by the presence of nucleosomes containing the centromere-specific histone H3 variant CENP-A, which is essential for chromosome segregation. Assembly and disassembly of nucleosomes is intimately linked to DNA topology and DNA topoisomerases have pr...

TranscriptomicsAnalysis of the DNA methylome and transcriptome in granulopoiesis reveal timed changes and dynamic enhancer methylation [expression]
The study investigated the changes in DNA-methylation and gene expression during granulopoiesis. To this end CMP, GMP, PMC and PMN cell populations were isolated by FACS from bonemarrow from healty donors and analysed by CAGE as well as expression and DNA microarrays total RNA was isolated from CMP,...

TranscriptomicsIdentification of histone codes and crosstalk in fission yeast
Aims: To map histone modifications with unprecedented resolution both globally and locus-specifically, and to link modification patterns to gene expression. Materials & methods: Using correlations between quantitative mass spectrometry and chromatin immunoprecipitation/microarray analyses, we have m...
