Sample GSM3955648 Query DataSets for GSM3955648
Status Public on Jul 20, 2019
Title 4
Sample type SRA
 
Source name Liver
Organism Xenopus tropicalis
Characteristics common name: tropical clawed frog
treatment: not exposed
Sex: female
Extracted molecule total RNA
Extraction protocol For each biological replicate, total RNA was extracted from 15 mg of liver using the RNAqueous®-4PCR Kit (Ambion, USA), according to the manufacturer's instructions. Total RNA quality and quantity were controlled on an Agilent 2100 Bioanalyzer (Agilent, USA). RNA-seq libraries were prepared using the TruSeq Stranded mRNA sample Prep kit (Illumina) and sequenced on an Illumina GAIIx sequencer as 75 bp reads by Hybrigenics-Helixio (Clermont-Ferrand, France).
TruSeq Stranded mRNA sample Prep kit
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina Genome Analyzer IIx
 
Data processing Reads were filtered based on their length, pairing, and quality using Trimmomatic (v0.32.1)
Cleaned reads were mapped to the Xenopus genome (JGI4.2 assembly) with Ensembl annotations (release 79) using Bowtie-0.12.7 / TopHat 2 (v0.6) software (81) (http://tophat.cbcb.umd.edu) (with a maximum intron size of 250,000 bp to discover novel junctions between exons).
The Cufflinks (v0.0.7) tool was applied to TopHat alignments to enumerate the number of short reads overlapping the Ensembl annotated genes, for each library
Genome_build: (JGI4.2 assembly)
Supplementary_files_format_and_content: GTF file from cufflink including gene ID, gene name and FPKM valuesfor gene expression
