Sample GSM3375577 Query DataSets for GSM3375577
Status Public on Feb 12, 2019
Title DM_TR_1
Sample type SRA
Source name whole worm
Organism Caenorhabditis elegans
Characteristics tissue: whole worm
treatment: Ad Libitum
fraction: polysome bound RNA
strain/genotype: daf-2;rsks-1
Treatment protocol Starting at day one of adults hood, worms were fed OP50 at 10^11 CFU for well fed treatment or at 10^9 CFU for dietary restriction.
Growth protocol Worms were raised at 20°C on nematode growth media with OP50 as the food source
Extracted molecule polyA RNA
Extraction protocol After lysis total RNA was isolated using Trizol as recommended by the manufacturer, polysomal bound RNA was collected using polysomal profiling with 10-50% sucrose gradients.
TruSeq RNA kit, unstranded
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 2000
Data processing Base call (.bcl) files for each cycle of sequencing are generated by Illumina Real Time Analysis (RTA) software. The base call files and run folders are streamed to servers maintained at the Minnesota Supercomputing Institute. Primary analysis and de-multiplexing are performed using Illumina’s bcl2fastq v2.20. The end result of the bcl2fastq workflow is de-multiplexed FASTQ files that are released to client accounts for subsequent analysis by the mapping software and aligner of their own choosing.
Aligned reads were counted per gene using the python script HTseq version 0.6.1 with the parameters: --stranded=no -a 0
Calculation of normalized counts per million (cpm) was performed using edgeR version 3.0. The dataset was normalized using the trimmed mean of M-values method with the calcNormFactors() command and tagwise dispersion was estimated using the estimateGLMTagwiseDisp() command. CPM values were exported using the command cpm() with the parameters: count=y,log=F,prior.count=0.03,normalized.lib.sizes=T.
Genome_build: Ensemble version 66
Supplementary_files_format_and_content: A single tab delimited file, CPM.txt contains the CPM for each for each sample submitted
