RiboZero Gold paired-end RNA-seq data from postmortem tissue of the dorsolateral prefrontal cortex of autism spectrum disorder samples and healthy control samples

ABSTRACT: Purpose: The goals of this study was to compare the expression of histamine related genes in ASD patients and controls. Methods: RNA-Seq was performed using strand-specific Ribosomal RNA depletion (RiboZero) library preparation and the TruSeq RNA Sample Preparation v2 kit from Illumina. One hundred base pair paired-end sequencing was run on the HiSeq 2000. TopHat (v2.0.4) was used to enforce strand specificity and to align the sequencing reads to known transcripts of the Ensembl Build GRCh37.67. FeatureCounts (v1.4.4) was used to count the total number of reads overlapping each gene using the default settings, with paired-end and reverse-stranded counting specified using the Ensembl Build GRCh37.67 gtf file. These counts were merged from both reads of the paired-end sequencing and normalized by library size and coding gene length to form Reads Per Kilobase of Gene per Million mapped reads (RPKM) values. The influence of diagnosis on expression was analyzed with linear regression transcriptome-wide and further evaluated using a gene set analysis. Results: There was no significant diagnosis effect on any of the individual genes but expression of the gene set of HNMT, HRH1, HRH2, and HRH3 was significantly altered. Conclusions: Our study represents the first specific analysis of the expression of histamine related genes in ASD and suggests that these genes may collectively be dysregulated.

Genome-wide expression from the esophageal biopsies of subjects with and without eosinophilic esophagitis

Project description:Esophageal biopsy RNA was isolated from distal esophageal biopsy RNA from EoE patients with active disease and from unaffected controls. EoE biopsies showed active disease pathology at the time when they were taken, and all patients reported no glucocorticoid treatment at the time of biopsy. RNA sequencing acquiring 50 million mappable 125 base-pair reads from paired-end libraries was performed at the Genetic Variation and Gene Discovery Core Facility at Cincinnati Children's Hospital Medical Center. Data were aligned to the hg19 build of the human genome using the Ensembl annotations as a guide for TopHat.

RNA-seq analysis comparing WT, Rad21 MO and CTCF MO zebrafish embryos at stages (2.5, 3.3, 4.5, 5.3, 10 hpf) pre and post ZGA (zygotic genome activation)

Project description:Methods: Triplicate RNA samples from morphologically stage-matched embryos were sequenced to compare expression profiles over time. Strand-specific libraries were prepared using the TruSeq stranded total RNA-ribozero kit (Illumina) and 100-bp paired-end sequencing was performed to depth of 10 million reads per library on an Illumina HiSeq 2000. Methods: On average, 19 million 100 bp paired-end reads per library were generated. These were then adapter and quality trimmed using cutadapt and SolexaQA. Each sequencing data set was independently mapped to the zebrafish genome with a bowtie2 index generated from Danio_rerio.Zv9.70 (Ensembl) downloaded from Illumina’s iGenomes collection. Zebrafish genome danRer7was used to provide known transcript annotations from Ensembl using TopHat2 (version 2.0.9) with the following options: “tophat2 --GTF genes.gtf --library-type fr-firststrand -p 24 --mate-inner-dist -8 --mate-std-dev 6 zv9” (on average, 75.38% reads mapped uniquely to the genome). Transcriptomes were assembled with Cufflinks (version 2.2.0) using options: ‘cufflinks -p 32 --GTF genes.gtf’ and differential expression analysis between control and knockdown embryos was performed using Cuffdiff. A FDR corrected p-value of 0.05 was applied as the cut off to identify differentially regulated transcripts Results: We could show that MO assisted depletion of Rad21 and CTCF affected the transcriptional profiles of embryos in different ways.

The effect of signal inhibitors on human induced pluripotent stem cells in suspension culture conditions

Project description:To examine the effect of the effects of PKCbeta and Wnt inhibitors on global gene expression of iPSCs in suspension conditions, RNA-seq experiments were performed. Total RNA was extracted with a FastGene RNA premium kit (Nippon Genetics, Co., Ltd, Tokyo, Japan) and strand-specific library preparation was performed. The prepared library was sequenced by a NovaSeq6000 (Illumina, Inc, CA, USA). Sequencing was performed in a 150 bp x2 paired-end configuration with a data output of about 6 Gb per sample (equivalent to about 20 million paired reads). Library preparation and its sequencing were performed in GENEWIZ (Azenta, MA, USA). The sequencing data were analyzed with a CLC Genomics Workbench (QIAGEN, Hulsterweg, the Neterlands) and the R package edgeR (v3.30.3) to identify differentially regulated genes.

Transcriptome profiling of two purebred cattle and their crossbreds

Project description:Purpose: The aim of this study is to determine the absolute and relative expresson levels of mRNA transcripts across two purbred (Angus and Brahman) cattle and their receipicalcross. Methods: Total RNA was extracted and purified from five tissues using the RiboZero Gold kit. Sequencing libraries were prepared with a KAPA Stranded RNA-Seq Library Preparation Kit following the Illumina paired-end library preparation protocol. Completed libraries were sequenced on HiSeq 2000 as 100 bp paired-end reads at the Australian Cancer Research Foundation (ACRF) Cancer Genomics Facility, Adelaide, Australia and USDA-ARS-US Meat Animal Research Center, Clay Center, USA. Approximately 60 million 100 bp single-end reads were obtained for each sample. Reads were aligned to the cattle reference genome UOA_brahman_1/UOA_angus_1 and mapped to known genomic features at the gene level using the Hisat2. Single reads were then summarized into gene-level counts using FeatureCounts.

Transcriptome profiling of Tasmanian Devil facial tumor (DFTD1) cell lines of 4 strains and the fibroblast cell line.

Project description:Purpose: To asses the transcriptome of 4 strains of the Tasmanian Devil facial tumor and one healthy fibroblast cell line. Methods: DFTD cells were grown from primary cell cultures derived from fine needle aspirates that have been collected from the wild. Total RNA from devil facial tumor strains 1-4 and the fibroblast was isolated from approximately 1 x 10^6 cells using QIAzol lysis reagent according to the manufacturer’s instructions (Qiagen). RNA-seq libraries were prepared with TruSeq Stranded mRNA LT sample preparation kit (Illumina) using Sciclone and Zephyr liquid handling robotics (PerkinElmer). The 5 libraries were pooled, diluted and sequenced on Illumina HiSeq 3000/4000 using 75 bp paired-end chemistry. Base calls provided by the Illumina Realtime Analysis software were converted into BAM format using Illumina2bam and demultiplexed using BamIndexDecoder. Paired-end reads were trimmed for adaptor sequences and filtered with the trimmomatic tool. Trimmed reads were aligned on the version 7.0 of the Tasmanian Devil with the STAR aligner. Counting of reads on annotated transcripts (Sarcophilus_harrisii.DEVIL7.0.90.gtf from Ensembl) was performed with featurecounts on fragments. The DESeq2 Biconductor library has been used for counts normalization and differential analysis between the transcriptomes of the four DFTD and fibroblast cell lines

Whole genome DNA methylation profiling of D2 medium spiny neurons in mouse nucleus accumbens using two independent library preparation methods

Project description:We isolated genomic DNA from adult male mouse nucleus accumbens (NAc) D2 medium spiny neurons (D2-MSN) by fluorescence-activated cell sorting. We performed the whole genome methylation profiling using two independent library preparation methods, namely the sodium bisulfite-based Accel-NGS Methyl-Seq (AM-seq) of Swift biosciences and the enzymatic conversion-based method Enzymatic Methyl-seq (EM-seq) from New England Biolabs, on two identical samples. We mapped about 400 million paired-end reads to the mouse genome (build mm10) and assessed measures of each methylome by two methods. This study provided a side-by-side comparison of two independent whole genome profiling methods for low-input neuronal samples.
