Sample GSM1558518 Query DataSets for GSM1558518
Status Public on Dec 04, 2014
Title Single-end_BRCA_rep2
Sample type SRA
 
Source name mammary glands
Organism Mus musculus
Characteristics gender: female
parity: nulliparous
strain: C57Bl/6
genotype: Brca1fl11/fl11/MMTV-Cre/p53+/-
tissue: mammary glands
Extracted molecule total RNA
Extraction protocol Total RNA was extracted from homogenized mammary glands using Trizol (Invitrogen) and 300μl chloroform (Thermo Fisher Scientific, Waltham, MA) for phase separation, precipitated with 650μl isopropanol (Thermo Fisher Scientific) and purified using an RNeasy Plus Mini Kit (Qiagen, Valencia, CA).
Polyadenylated (polyA) RNA was isolated from 1ug total RNA and converted to cDNA using SuperScript II (Invitrogen). A TruSeq RNA Sample Preparation Kit (Illumina, San Diego, CA) was used to generate sequencing libraries according to the manufacturer’s instructions. Libraries were independently sequenced by both single- and paired-end methods using HiSeq 2000 (Illumina).
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 2000
 
Data processing FastQC was used to evaluate quality of sequenced reads (http://www.bioinformatics.babraham.ac.uk/project/fastqc), and contaminated adaptor portions of sequenced reads were trimmed using the Trim Galore program (http://www.bioinformatics.babraham.ac.uk/project/trim_galore).
Single- and paired-end reads of each biological replicate (single-end: two replicates of WT, Esr1, CYP19A1 and Brca1 KO; paired-end: one WT, two replicates of Brca1 KO and three replicates of Esr1 and CYP19A1) were aligned to the mouse reference genome (mm9 assembly) using TopHat.
Cufflinks was used to assemble transcriptomes, estimate the abundance of transcripts (FPKM, Fragments Per Kilobase of transcript per Million mapped reads) and identify differentially expressed genes (DEGs).
