Sample GSM3019735 Query DataSets for GSM3019735
Status Public on Nov 21, 2018
Title hif13
Sample type SRA
 
Source name Whole worm
Organism Caenorhabditis elegans
Characteristics tissue: Whole worm
developmental stage: prefertile young adult
sequencing batch: 1
Growth protocol NGM plates, 20 degrees Celsius, OP50 bacteria
Extracted molecule total RNA
Extraction protocol See Schaar et al. 2015 PLoS Genetics for RNA isolation protocol
Sequencing libraries were prepared using the Kapa Biosystems stranded mRNA-Seq kit for the Illumina platform.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina NextSeq 500
 
Data processing Libraries were sequenced using 1x75 bp sequencing on the Illumina NextSeq 500 platform at the Van Andel Research Institute. Data were demultplexed using bcl2fastq v 2.18.
Read quality was assessed using FASTQC v. 0.11.5 and aligned first to the E. coli K-12 genome to assess contamination, then one-pass aligned to WBcel235 C. elegans genome using STAR v. 2.5.2b with default parameters and --outReadsUnmapped None. The STAR genome index was generated with the corresponding Ensembl WBcel235 build 89 GTF annotations integrated.
Transcript abundances were quantified using the --quantMode GeneCounts option enabled during alignment. Differential gene expression analysis was performed using the quasi-likelihood framework in edgeR package v. 3.20.1 in R v. 3.4.1. The model used for DGE accounts for sequencing batch and genotype and is as follows: design <- model.matrix(~seqbatch + genotype). Gene names, gene IDs, and predicted function annotations were downloaded using the biomaRt package v. 2.34.0.
Filtered CPM were filtered keeping genes that had CPM > 2 in at least 3 samples. Raw CPM are unfiltered.
Genome_build: WBcel235
Supplementary_files_format_and_content: Text file containing filtered gene counts per million matrix (CPM) from all samples.
