Description
Positioned nucleosomes limit the access of proteins to DNA and implement regulatory features encoded in eukaryotic genomes. Here we generated the first genome-wide nucleosome positioning map for Schizosaccharomyces pombe and annotated transcription start and termination sites genome-wide. Using this resource we found surprising differences compared to the nucleosome organization in the distantly related yeast Saccharomyces cerevisiae [the cerevisiae data has been published by others (PMID: 17873876) and the raw data is deposited at ArrayExpress(E-MEXP-1172)]. DNA sequence guides nucleosome positioning differently, e.g., poly(dA:dT) elements are not enriched in S. pombe nucleosome-depleted regions (NDRs). Regular nucleosomal arrays emanate more asymmetrically, i.e., mainly co-directionally with transcription, from promoter NDRs, but promoters harbouring the histone variant H2A.Z show regular arrays also upstream. Regular nucleosome phasing in S. pombe has a very short repeat length of 154 base pairs, and requires a remodeler, Mit1, conserved in humans but not found in S. cerevisiae. Nucleosome positioning mechanisms are evidently not universal but evolutionarily plastic.

IlluminaHiSeq2000
Description
Coilin iCLIP data revealed 42 novel human snoRNAs of intronic origin. To validate their expression and estimate abundance of novel and annotated snoRNAs, we performed RNA-seq on polyA- and rRNA-depleted RNA isolated from HeLa cells. Results show that expression of novel snoRNAs is comparable to the previously annotated snoRNAs. Overall design: 1 replicate of RNA depleted of polyA and ribosomal RNA.
Publication Title
The coilin interactome identifies hundreds of small noncoding RNAs that traffic through Cajal bodies.

- Affymetrix Drosophila Genome 2.0 Array (drosophila2)
Description
The H4K16 acetyltransferase MOF plays a crucial role in dosage compensation in Drosophila, but has additional, global functions in gene control. We compared the molecular context and effect of MOF activity in male and female flies combining chromosome-wide mapping and transcriptome studies with analyses of defined reporter loci in transgenic flies. MOF distributes dynamically between two types of complexes, the Dosage Compensation Complex (DCC) and complexes containing MBD-R2, a global facilitator of transcription. These different targeting principles define the distribution of MOF between the X chromosome and autosomes and at transcription units with 5 or 3 enrichment.
Publication Title
The activation potential of MOF is constrained for dosage compensation.

Description
Thoracic perivascular adipose tissue (PVAT) is a unique adipose depot that likely influences vascular function and susceptibility to pathogenesis in obesity and metabolic syndrome. Surprisingly, PVAT has been reported to share characteristics of both brown and white adipose, but a detailed direct comparison to interscapular brown adipose tissue (BAT) has not been performed. Here we show by full genome DNA microarray analysis that global gene expression profiles of PVAT are virtually identical to BAT, with equally high expression of Ucp-1, Cidea and other genes known to be uniquely or very highly expressed in BAT. PVAT and BAT also displayed nearly identical phenotypes upon immunohistochemical analysis, and electron microscopy confirmed that PVAT contained multilocular lipid droplets and abundant mitochondria. Compared to white adipose tissue (WAT), PVAT and BAT from C57BL/6 mice fed a high fat diet for 13 weeks had markedly lower expression of immune cell-enriched mRNAs, suggesting resistance to obesity-induced inflammation. Indeed, staining of BAT and PVAT for macrophage markers (F4/80, CD68) in obese mice showed virtually no macrophage infiltration, and FACS analysis of BAT confirmed the presence of very few CD11b+/CD11c+ macrophages in BAT (1.0%) in comparison to WAT (31%). In summary, murine PVAT from the thoracic aorta is virtually identical to interscapular BAT, is resistant to diet-induced macrophage infiltration, and thus may play an important role in protecting the vascular bed from thermal and inflammatory stress.

Description
The MOF-containing NSL complex binds to many but not all promoters of active genes and potentially contributes to their proper gene expression. It is currently unknown what determines whether an active gene is bound or not. Here, we provide evidence that the NSL complex primarily targets active promoters of most housekeeping genes. There, it co-localizes with the chromatin remodeler NURF and the histone methyltransferase Trithorax. Moreover, despite binding to most housekeeping genes, the NSL complex regulates only a subset of them, which are depleted for certain insulator binding-proteins and enriched for the core promoter motif Ohler 5. We suggest that the combination of general chromatin factors and core promoter motifs is predictive for whether a housekeeping gene is transcriptionally regulated by the NSL complex.
