Sample GSM1077265 Query DataSets for GSM1077265
Status Public on Feb 07, 2013
Title HeLa Sh-Scr 3
Sample type SRA
 
Source name HeLa Sh-Scr
Organism Homo sapiens
Characteristics cell line: HeLa
cell type: cervical cancer cells
genotype/variation: stably expressing double-strand (ds) interfering RNA against scrambled sequences (sh-Scr)
molecule subtype: small RNA
Treatment protocol Sub-confluent HeLa cells were transfected with Nucleolin shRNA (sc-29230-SH) or Control shRNA (sc-3314-SH) plasmids, and stably transfected clones were selected by using 1 µg/ml puromycin.
Growth protocol HeLa cells were cultured in Dulbecco’s Modified Eagle Medium (DMEM) with 10% FBS, L-glutamine, and antibiotics (Life Technologies; Invitrogen).
Extracted molecule total RNA
Extraction protocol Total RNA was prepared using Trizol® (Invitrogen) and libraries for deep sequencing were prepared from 2 µg of total RNA. Specifically 2 µg of total RNA underwent size selection by Flashpage Fractionator (AM110226001 Life Technologies). RNA that was 40bp and under was then quality checked by RNA pico-chip from Agilent.
The Applied Biosystems Total RNA-Seq Kit (cat # 4445374) was used to produce a cDNA library by the following steps. 5’ and 3’ specific adapters undergo hybridization and ligation to the RNA. cDNA was produced by reverse transcription and then purified and size-selected on a gel. The gel slices containing the cDNA library were amplified by PCR with primers specific to the adapter sequences, and then purified and sized selected on a gel. Templated sequencing beads were produced via emulsion PCR with Applied Biosystems’ EZ Bead system. The templated sequencing beads were sequenced on an Applied Biosystems SOLiD 5500 system according to the manufacturer’s protocol (Life Technologies, Foster City).

Description 40_Hela_ctr3_solid0379_20110818_FRAGBCKal5Fla6mirRNA_solid0379_20110818_FRAGBCKal5Fla6mirRNA_F3_40_Hela_ctr3
Data processing Mapping of SOLiD reads was performed using both the small RNA pipeline (Life Technologies) and PASS (Campagna et al., 2009). The small RNA pipeline and PASS were used to extract counts and extensions of miRNA in small RNA reads, from 18 nucleotides in length.
Alignments with up to one mismatch has been recorded when matching to either miRNome (precursor sequences from miRBase) or human genome. Only reads with at least 3 sequenced copies per sample were inputted in the SQL database.
Raw digital expression values (read counts) were obtained by summing the number of reads that mapped to one of the reference databases
Genome_build: human genome hg19 or miRBase release 17.0
