Sample GSM3445685 Query DataSets for GSM3445685
Status Public on Jan 01, 2019
Title intron-DARP-EGFP line scrambled siRNA replicate 3
Sample type SRA
 
Source name Human embryonic kidney
Organism Homo sapiens
Characteristics cell line: HEK293
reporter: endogenous intronic sequence + DARP
exogenous gene expressed: DARP-EGFP
treatment: scrambled siRNAs
ercc mix: mix1
hours post-infection: 72 hours
rin: 10
replicate: 3
Treatment protocol Cells were transfected at 50% confluency in 6-well plates by combining either SUPT4H1 siRNA or scramble siRNA with 9 ul of RNAi max transfection reagent (Invitrogen) at a final concentration of 100 nM in a total volumne of 1.3 ml.
Growth protocol HEK293 CRL-1573 (ATCC) cells were cultured in DMEM, 10% FBS, 100 units/ml penicillin and streptomycin, 37 deg.C, 5% carbon dioxide, 100% humidity
Extracted molecule total RNA
Extraction protocol 72 hours post transfection, total RNA was extracted with the RNEasy (Qiagen) kit from 1,000,000 cells per sample. Either ERCC mix1 or mix2 external standards (Invitrogen) were diluted 1:100 in water and 2 ul was added to each lysate.
Sequencing libraries were generated using the QuantSeq 3’ mRNA-Seq Library Prep Kit FWD for Illumina (Lexogen). 200 ng RNA was used for library preparation for each sample.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 4000

Data processing Sequencing adapters were trimmed using skewer (Jiang et al., 2014; version 0.2.2) with default parameters. Quality control of the trimmed reads was performed using FastQC (version 0.11.5: www.bioinformatics.babraham.ac.uk/projects/fastqc).
Reads were aligned to a composite index of the human genome (version GRCh38_p10) and sequences of the 92 ERCC spike-in transcripts: A STAR index (Dobin et al., 2013; version 2.5.3a) was built with the --sjdbOverhang=50 argument. Splice junctions from Gencode gene models (release 27) were provided via the --sjdbGTFfile argument. STAR alignments were generated with the following parameters: --outFilterType BySJout --quantMode TranscriptomeSAM --outFilterIntronMotifs RemoveNoncanonicalUnannotated --outSAMstrandField intronMotif --outSAMattributes NH HI AS nM MD XS --outSAMunmapped Within. Post-alignment quality control reports were generated using MultiQC (Ewels et al., 2016; version 1.0).
The raw gene expression matrix was constructed from the 'forward' column of STAR's ReadsPerGene.out.tab output files using R (version 3.4.3). Gene symbols and Entrez gene identifiers were mapped using Ensembl (version 86) via the biomaRt R package (Durinck et al, 2009; version 2.34.0).
