Affymetrix Drosophila Genome 2.0 Array (drosophila2)
Description
Alphaviruses establish a persistent infection in arthropod vectors, which is essential for effective transmission of the virus to vertebrate hosts. The development of persistence in insects is not well understood, although it is thought to involve the innate immune response. Using a transgenic fly system (SINrep) expressing a self-replicating viral genome, we have previously demonstrated the antiviral response of the Drosophila Imd (Immune Deficiency) and Jak-STAT innate immunity pathways.

Description
Polycomb repressive complex 2 (PRC2-EZH2) methylates histone H3 at lysine 27 (H3K27) and is required to maintain gene repression during development. Misregulation of PRC2 is linked to a range of neoplastic malignancies, which is believed to involve methylation of H3K27. However, the full spectrum of non-histone substrates of PRC2 that might also contribute to PRC2 function is not known. We characterized the target recognition specificity of PRC2 and used the resultant data to screen for novel potential targets. The RNA polymerase II (Pol II) transcription factor, Elongin A (EloA), is methylated by PRC2 in vivo. Mutation of the methylated EloA residue decreased repression of many, but not all, PRC2 target genes as measured by both steady state and nascent RNA levels. We propose that PRC2 regulates transcription of a subset of target genes in part via methylation of EloA. Overall design: We examined the transcripitonal profile of EEDnull, EloAnull, EloA mutant, and parental mouse embryonic stem cells by RNAseq. Please note that the .bw processed data file was generated from the *mESC replicate samples together and linked to the corresponding *rep1 sample records.

Overall design: We examined the nascent transcripiton profile of mES cells by adding 5-Bromouridine (BrU) to the media for 10 min. Following RNA isolation, BrU-labelled nascent RNA species were affinity purified using BrdU antibody and sequenced after library preparation. Please note that each .bw file was generated from two replicate samples together and linked to the corresponding *rep1 sample records.

Description
Most vertebrate organs are composed of epithelium surrounded by support and stromal tissues formed from mesenchyme cells, which are not generally thought to form organized progenitor pools. Here we use clonal cell labeling with multicolor reporters to characterize individual mesenchymal progenitors in the developing mouse lung. We observe a diversity of mesenchymal progenitor populations with different locations, movements, and lineage boundaries. Airway smooth muscle (ASM) progenitors map exclusively to mesenchyme ahead of budding airways. Progenitors recruited from these tip pools differentiate into ASM around airway stalks; flanking stalk mesenchyme can be induced to form an ASM niche by a lateral bud or by an airway tip plus focal Wnt signal. Thus, mesenchymal progenitors can be organized into localized and carefully controlled domains that rival epithelial progenitor niches in regulatory sophistication.

Description
Master regulatory genes require stable silencing by the Polycomb-Group (PcG) to prevent improper expression during differentiation and development. Some PcG proteins covalently modify histones, which contributes to heritable repression. The role for other effects on chromatin structure is less understood. We characterized the organization of PcG target genes in mouse ES cells and neural progenitors using high-resolution 5C technology and super-resolution microscopy. The genomic loci of repressed PcG target genes formed discrete, small domains of tight interaction that corresponded to locations bound by canonical Polycomb Repressive Complex 1 (PRC1). These domains changed during differentiation as PRC1 binding changed. Their formation depended upon the Polyhomeotic component of canonical PRC1, and occurred independently of PRC1-catalyzed ubiquitylation. PRC1 domains differ from topologically associating domains in numerous aspects . These domains have the potential to play a key role in transmitting epigenetic silencing of PcG targets by linking PRC1 to formation of a repressive higher order structure. Overall design: RNA-Seq was performed to compare gene expression of in vitro derived NPC and Phc1 knock-out mESC with wild type ESC. Experiments were performed in dupicates. 50base single end sequencing was performed on Illumina HiSeq2000. Reference genome is mm9.

Description
We profiled genome-wide accesssible chromatin data and RNA-seq from four species (zebrafish, stickleback, mouse, and human) to identify commonly regulated genes and regulatory metods in intestinal epithelial cells (IECs). We identify a group genes that are commonly expressed in IECs and genes that are commonly expressed along the length of the intestine in fish and mammals. Using accessible chromatin data we identified enriched transcription factor binding site motifs In IECs and sites that are commonly accessible in IECs in all species. Finally, we confirm the ability for these regions from multiple species to drive conserved expression in IECs using a zebrafish reporter assay. Overall design: Examination of expression levels and chromatin accessibility in intestinal epithelaial cells in zebrafish
