Project description:Stroma extracts were isolated from 2-week-old WT plants and incubated with either BSF-specific antibodies or with the pre-immune serum. IgGs were captured with SiMAG-Protein G beads (Chemicell) and recovered RNA was used for generation of libraries with the ScriptSeq v2 RNA-seq Library Preparation Kit (Epicentre). Primary reads were aligned to the Arabidopsis chloroplast genome (accession number NC_000932.1) using CLC Genomics Workbench. BAM files were extracted and sorted in Galaxy . Sorted BAM files were converted into RPKM-normalized bigwig files and displayed in IGB. The differential enrichment of BSF/control of the two replicates was displayed across the entire chloroplast genome to identify the RNA targets of BSF.
Project description:In vertebrates, the catalytic core of PRC1 comprises RING1A/B and one of six homologues of the Polycomb group RING finger (PCGF) protein. Unique characteristics of PCGF1-6 in turn define distinct subunit assemblies, broadly subdivided into canonical and non-canonical PRC1 complexes. This RNA-seq experiment aimed to test the hypothesis that Pcgf3/5 gene knockout abrogates Xist mediated gene repression. In this experiment, Pcgf3fl/flPcgf5-/- and Pcgf3-/-Pcgf5-/- mESCs bearing Xist transgene on chromosome 16 (clone C3F8) were cultured in differentiating conditions: plated on non-gelatinized TC dish in ES medium without LIF for 72 hours with (+dox) and without doxycycline. RNA was isolated from 4 biological replicates. In analysed cells chromosome 16 bears inducible Xist and the whole study investigates role of PCGF3 and PCGF5 in Xist-dependednt gene silencing, therefore both bam files containing alignments and counts per gene were uploaded to ArrayExpress only for chromosome 16. Genome-wide data can be provided upon request.
Project description:Purpose: A method for mapping chromatin accessibility genome-wide, to reveal chromatin accessibility in Intestinal stem cells. Methods: Intestinal stem cells(Lgr5-high cells) were sorted by flow cytometry from wild type mice. The samples were prepared in duplicate. HISAT2 was used to align the sequences to the mouse genome and generate bam files. bamCoverage was used to generate bigwig files from bam files. MACS2 (v2.2.5) was used for peak calling and to generate bed files from aligned reads. Conclusions: ATAC-seq analysis confirmed that Fosb binding sites in Chip-seq assay were correlated with the chromatin accessibility .
Project description:This dataset provides the transcriptome of the central cell of the female gametophyte from Arabidopsis thaliana. We sequenced two biological replicates. Each replicate started with a pool of 450 central cells collected using laser-assisted microdissection (LAM). Libraries were prepared as described in DOI:10.1038/NMETH.1315. Each library was sequenced on one eight of a slide on the AB SOLiD platform (version 3). IMPORTANT: In the alignment files (.bam), we named the mitochondrial and the chloroplastidial chromosomes ChrM and ChrC. This is different from the "chloroplast" and "mitochondrium" names in the whole genome fasta file available on TAIR.
Project description:The expression profile and sequence variants of 476 early stage urothelial carcinoma were studied using whole transcriptome sequencing. RNA-Seq libraries were prepared by Ribo-Zero treatment of total-RNA (to reduce the rRNA content) followed by library preparation using ScriptSeq. RNA-Seq libraries were paired-end sequenced (2x 101 bp) on Illumina HiSeq 2000 and the resulting fastq files were processed using tools from the Genome Analysis Toolkit (GATK and from the Tuxedo suite. Access to the sequence data (bam and vcf files), containing person identifying information, needs signature on a controlled access form, and can be accessed at The European Genome-phenome Archive (EGA) using the study ID EGAS00001001236 following request. An expression matrix of FPKM values are available without restriction at ArrayExpress.
Project description:Purpose: A method for identifying genome-wide DNA binding sites for Fosb. Methods: Alive cells were sorted from retro-Fosb-OE(over-expression) organoids. The samples were incubated with anti-Fosb antibody (Abcam, ab184938). Purified DNA was subjected to Tru-seq library construction using NEBNext Ultra II DNA Library Prep Kit and sequenced as paired-end with Illumina Novaseq 6000. HISAT2 was used to align the sequences to the mouse genome and generate bam files. bamCoverage (CPM normalized and extended reads) was used to generate bigwig files from bam files. MACS2 was used for peak calling and to generate bed files from aligned reads. HOMER annotatePeaks.pl was used to annotate the peaks. Conclusions: Target genes of Fosb through ChIP assay were consistent with predicted target genes. Thus, we concluded that Fosb, which is a key TF could regulate most of ISC signature genes to maintain Lgr5+ ISCs.
