Sample GSM2386576 Query DataSets for GSM2386576
Status Public on Apr 17, 2017
Title H1_1
Sample type SRA
 
Source name H1 POU5F1-IRES-eGFP
Organism Homo sapiens
Characteristics cell type: H1 POU5F1-eGFP reporter cells
Treatment protocol Regular hESC culture without any special treatment.
The core promoter of MSH5 and PRRC2A was deleted by a pair of CRISPR/Cas9 targeting- 150bp to +100bp region near TSS. After picking single clones and Sanger sequencing verification of the genotype, the mutant cells and wild-type control cells were subjected to ATAC-seq analysis.
Growth protocol Cells were cultured at 37 celsius degree in 5% CO2, in Essential 8 media (Stemcell Technologies).
Extracted molecule genomic DNA
Extraction protocol ATAC-seq was performed by following the protocol described earlier (Buenrostro et al, Nature Method, 2013).
Briefly, each library starts with 100k cells which were permeabilized with NPB (0.2% NP-40, 5%BSA, 1Mm DTT in PBS with one complete proteinase inhibitor) at 4 degree for 10min, followed by spin down at 500g for 5min. The resulting nuclei were resuspended in 20ul 1xDMF (33mM Tris-acetate (pH=7.8), 166mM K-Acetate, 10mM Mg-Acetate, 16 % DMF). The chromatin tagmentation was done by adding 0.5ul Tn5 into 10ul solution for 30min at 37 degrees, followed by standar Illumina Tru-seq library prep protocol.

Description ATAC-seq using WT and mutant POU5F1-eGFP reporter hESC.
POU5F1-eGFP H1 hESC reporter cells purchased from WiWell Institute.
Data processing Library strategy: ATAC-seq
We processed our ATAC-seq data in the following steps: 1) ATAC-seq sequencing reads were mapped to hg19 reference genome using Bowtie(61) in pair-end mode; 2) poorly mapped, improperly paired and mitochondrial reads were filtered; 3) PCR duplications were further removed using Picards MarkDuplicates (http://broadinstitute.github.io/picard.); 4) Mapping positions of reads were adjusted accounting for Tn5 insertion; 6) Reads were next shifted for 75bp followed by peak calling using MACS2(71) with following parameters “-q 0.01 --nomodel --shift 175 –B --SPMR --keep-dup all --call-summits”; 7) ATAC-seq signal was normalized into RPKM using deeptools(72) for visualization.
