Project description:20 random DNA barcodes were designed in silico and transfected into PC3 cells. Barcodes were sequenced using Illumina-Miseq technology to find the sequence and their respective copy numbers. Current file contains the raw data of these DNA barcodes in fastq format
Project description:Raw RNAseq data (fastq) files that were analyzed for circadian changes in RNA ribosome binding. The numbers in the file names (00 - 44) represent circadian time (0 to 44 hours in constant dark and constant temperature). Two separate sets of samples (independent biological replicates) were collected over a 44-hour period of time.
Project description:Temporal analysis of Irf4 and PU.1 genome binding during B cell activation and differentiation in vitro using antigen (NP-Ficoll) CD40L and IL-2/4/5 cytokines (see Molecular Systems Biology 7:495 for details of cellular system). The results provide insight in the target genes and binding specificity of IRF4 and PU.1 during coordination of different programs of B cell differentiation. Regrettably three of the FASTQ raw sequence files in our study were corrupted during storage. FASTQ data from our experimental and control groups are available for download via GEO SRA; however, two groups are missing select raw sequence files. These include one PU.1 Day 3 group file (Sample GSM1133499) and two of four input files used to generate a concatenated “super” input file (Sample GSM1133490); the raw data provided for input consists of the two input files recovered. Importantly, FASTA sequences for both of these datasets are available as supplementary data through GEO, and we can make available upon request (rsciamma@uchicago.edu) all files in our study in the ELAND-extended alignment format. Please note that GEO no longer supports this format.
Project description:Chromatin accessibility mapping by DNase-seq on whole embryo and FACS-isolated cell populations during Drosophila melanogaster embryogenesis at 2-4 hrs, 4-6 hrs, 6-8 hrs, 8-10 hrs and 10-12 hrs after egg-laying. Note that the two 8 bases long UMIs clipped from read1 and read2 are present in the FastQ file header (followed by the 8 bp long invariant sample barcode)
Project description:Purpose: The goal of this study is to compare NGS-derived transcriptomes of wild type mouse small interstinal organoids and organoids deficient for the enzyme acetyl-coa-carboxylase (ACC) 1 (Acaca). Methods: mRNA profiles were generated from organoids at 24h and 96h upon in vitro deletion of the Acaca gene and the respective non-deleted wild type controls in triplicates. Total RNA was isolated using RNeasy Micro Kit (Qiagen) and libraries were prepared using NEBNext Single Cell/Low Input RNA Library Prep (New England BioLabs). The libraries were sequenced on Illumina NovaSeq 6000 using NovaSeq 6000 S2 Reagent Kit (100 cycles, paired end run). Each FASTQ file gets a quality report generated by FASTQC tool. Before alignment to reference genome each sequence in the raw FASTQ files were trimmed on base call quality and sequencing adapter contamination using Trim Galore! wrapper tool. Reads shorter than 20 bp were removed from FASTQ file. Trimmed reads were aligned to the reference genome (GRCm38.) using open source short read aligner STAR (https://code.google.com/p/rna-star/) with settings according to log file. Results: the sequencing depth of our libraries is > 3 x107 reads per RNA sample. PCA analysis revealed a close relationship between WT and ACC1-deficient organoids at 24h, whereas samples at 96h were distinct from each other. Lack of ACC1 strongly reduced the expression of genes associated with intestinal epitelial stem cells. Moreover, GSEA revealed downregulation of pathways associated with DNA replication, cell cycle and chromosome segregation in ACC1-deficient organoids. Conclusions: Our study highlights the importance of ACC1-mediated cellular fatty acid synthesis for the maintenance of intestinal epithelial stem cells in mouse intestinal oganoids.
