Sample GSM3391424 Query DataSets for GSM3391424
Status Public on May 29, 2019
Title N2 rep3
Sample type SRA
 
Source name Whole animal
Organism Caenorhabditis elegans
Characteristics strain: N2
tissue: Whole animal
age: Day 1 adult
genotype: wild-type
Growth protocol All strains were maintained at 20˚C on nematode growth medium (NGM) plates seeded with E. coli (OP50 strain). Unhatched eggs were age-synchronized and after 3 days, day 1 adult worms were harvested for RNA extraction.
Extracted molecule total RNA
Extraction protocol TRIzol reagent (Thermo Fisher) was used to extract total RNA from ~1,000 age-synchronized day 1 adult worms (three biological replicates per genotype). DNase-treatment was performed using TURBO DNA-free kit (Themo Fisher). mRNA was isolated from the DNase-treated total RNA using oligo(dT) and cDNA was synthesized by reverse transcription using TruSeq RNA Library Prep Kit v2 (Illumina).
The samples were end-repaired, poly(A)-tailed, ligated to barcoded oligo adapters (Illumina) and PCR-amplified using Apollo 324 library preparation system (Wafergen Bio-systems) to prepare non-stranded poly(A)-based cDNA libraries with 120 bp insert size.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 2500
 
Description Sample_41028
Data processing Basecalling was performed using HiSeq Control Software (Illumina)
Quality control of raw RNA-Seq reads was performed using FastQC
Tuxedo Suite was used for alignment, differential expression analysis and post-analysis diagnostics
RNA-Seq reads were aligned to the C. elegans reference transcriptome (WS220 release) using Bowtie 2
Transcript splicing junctions were mapped using TopHat
FastQC was used for post-alignment quality control to ensure high quality of input data for subsequent analysis steps
Cufflinks was used to assemble the aligned reads, estimate abundance of transcripts and calculate FPKM values
Transcripts that were differentially expressed relative to wild-type were determined using CuffDiff 2 using the following two criteria: false discovery rate (FDR)-adjusted p value < 0.05 and fold-change ≥ 1.5
