Sample GSM2125494 Query DataSets for GSM2125494
Status Public on Jun 12, 2017
Title 48h_scrambled_D-siRNA_1
Sample type SRA
Source name 48h_scrambled_D-siRNA
Organism Homo sapiens
Characteristics donor: 195307
cell type: Human bronchial epithelial cells HBECs
passage: 3
source: Lonza
transfected with: scrambled_D-siRNA
time point: 48h since the initiation of knockdown
Treatment protocol RNAseq: Effects of INTS12 depletion were assessed 120h and 48h after the initiation of interference.There were four experimental conditions: un-transfected cells, cells transfected with scrambled D-siRNA control, and cells transfected with D-siRNAs A and C. Each experimental condition was performed in three independent biological replicates.
ChIP-seq: Cells were formaldyhade fixed. Chromatin was isolated by the addition of lysis buffer. Genomic DNA for each replicate sample was prepared by treating aliquots of chromatin with RNase, proteinase K and heat for de-crosslinking, followed by ethanol precipitation.
Growth protocol Human bronchial epithelial cells HBECs were purchased from Clonetics-Biowhittaker (MD, USA). Cells were cultured in HBEC basal medium (BEGM) from Lonza (Berkshire, UK) prepared by addition of all the recommended supplements per manufacturer specifications excluding gentamicin. All laboratory experiments were performed using passage 3 cells. Prior to experiments cells were grown at 37oC with 5% CO2 until ~95% confluent with BEGM media change every ~48h
Extracted molecule total RNA
Extraction protocol RNAseq: Total RNA was extracted using a mammalian total RNA prep kit with on-column DNaseI digestion
ChIP-seq: Unprecipitated genomic DNA (i.e. input control) was prepared from a pool of equal aliquots of the two donor samples. Genomic DNA regions of interest were isolated using 4 µg of antibody against INTS12 (Sigma cat. num. HPA03577) following manufacturer’s specifications (Active Motif).
RNA-seq: The sequencing libraries were prepared with Illumina TruSeq RNA Sample Prep Kit v2. mRNA was poly-A selected by capturing total RNA samples with oligo-dT coated magnetic beads. The mRNA was then fragmented and randomly primed. cDNA was synthesised using random primers. Finally a ready-for-sequencing library was prepared by end-repair, phosphorylation, A-tailing, adapter ligation and PCR amplification. Paired-end sequencing was performed on the HiSeq2000 platform (Illumina) using TruSeq v3 chemistry over 100 cycles yielding ~40 million reads per sample.
ChIP-seq: Libraries (Illumina) were prepared from the both ChIP and input DNAs and the resulting libraries were sequenced yielding ~40 million reads per two ChIP samples from each donor cells and one input control of both donors. DNA libraries obtained from single donor were sequenced on NextSeq 500 sequencing machine
