Sample GSM1192672 Query DataSets for GSM1192672
Status Public on Jul 20, 2013
Title 28_s_5
Sample type SRA
 
Source name serum
Organism Homo sapiens
Characteristics er status: neg
pr status: neg
her2 status: pos
inflammatory: Y
Stage: 3
relapse: N
molecule subtype: miRNA
Treatment protocol Pre-treatment sera from BC patients were used.
Growth protocol N/A
Extracted molecule total RNA
Extraction protocol TRIZOL LS reagent (Invitrogen) was used to extract total RNA from ~1.5 ml of serum, as described in the manufacturer’s protocol. RNA pellet was dissolved in 10 μl of RNase-free water, and subjected to library construction and deep sequencing.
Each serum sample was independently subjected to library preparation and deep sequencing. All small RNAs of 15–52 nts were selected and sequenced using the Solexa system, following the manufacturer’s protocol (Illumina Inc., San Diego, CA). Library preparation, as well as cluster generation and deep sequencing, was performed according to the 5' ligation-dependent (5′ monophosphate-dependent) manufacturer’s protocol (Digital Gene Expression for small RNA; Illumina). For each sample, 5 μl of total RNA extracted from serum was used for small RNA library preparation. Small RNAs were size-selected between 17 and 52 nt according to the single-stranded DNA marker in the small RNA sequencing kit (Illumina). The library was quantified using picoGreen and qPCR. Sequencing was performed on a Genome Analyzer IIx (Illumina), and image processing and base calling were conducted using Illumina’s pipeline.
 
Library strategy RNA-Seq

Description 28_s_5 serum
Data processing Sequenced reads from Solexa were first mapped onto human genome version hg18 using novoalign software and the expression level of mature miRNAs in the miRBase human miRNA database v15 was summarized.
Quantile normalization was applied to the counts data
Genome_build: hg18
Supplementary_files_format_and_content: tab-delimited text files include normalized read counts for each miRNA
