Sample GSM2112748 Query DataSets for GSM2112748
Status Public on Jun 01, 2016
Title Tumor_P8_E2_24 Hours_RNAseq
Sample type SRA
 
Source name Breast cancer cells
Organism Homo sapiens
Characteristics tissue type: ER+/PR+ Human tumor explants
er/pr status: ER+/PR+
drug treatment: 10 nM Estradiol
hormone exposure time: 24 Hours
Treatment protocol Steroid-deprived tumor explants were treated with 10 nM estradiol, 10 nM R5020 or 10 nM of both the hormones for 24 or 48 hours. Finer details are provided in materials and methods section (Patient tumor explants)
Growth protocol Tumor explants: Within one hour of surgery, sliced pieces of tumors were incubated on gelatin sponges for 36 hours in charcoal-stripped serum media. Representative pieces of tumors were in parallel fixed in 4% formalin and subsequently immunohistochemistry for ER and PR protein was performed to assess the status of tumors for these receptors.
Extracted molecule polyA RNA
Extraction protocol Hormone-treated explant was homogenized and total RNA was extracted using Qiagen RNAeasy kit
PolyA tail selection was performed on 250 ng of total RNA. RNA-seq libraries were prepared using NEBNext kit.
Details of library preparation strategy are provided in the materials and methods section (RNA expression and RNA-sequencing) of the paper.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 2500
 
Description Processed data file: Tumor P8.csv
Data processing The FASTQ files were filtered and good quality reads were groomed and subsequently aligned to HG19 genome build using TopHat.
Relative expression of transcripts were calculated by subjecting TopHat output (BAM files) to Cufflinks package.
Cufflinks assemblies obtained from Cufflinks package were merged using cuffmerge. For every model system, cufflink assemblies of each of the treatments were merged with the cufflinks assemblies of the respective vehicle-treated samples.
The output from Cuffmerge along with the corresponding TopHat output (BAM files) were subjected to Cuffdiff to calculate transcript expression.
Genes that were up or down regulated by at least two fold were used for downstream analyses.
Genome_build: HG19
Supplementary_files_format_and_content: CSV includes RPKM values for each each of the treatment conditions (E2, R5020 or E2+R5020) versus control treatment. Union of all estrogen and progestin-regulated genes for the respective samples is provided.
