Sample GSM3635747 Query DataSets for GSM3635747
Status Public on Nov 17, 2020
Title H3K4me3-AB2-hNSC-H7-WT
Sample type SRA
 
Source name Cell Line
Organism Homo sapiens
Characteristics cell type: Human Neural Stem Cells H7
chip antibody: H3K4me3(Diagenode,C15410003-50)
Treatment protocol On day 5, EBs were re-plated onto Matrigel-treated 6-well plates. Neural differentiation (STEMCELL Technologies, #08500) started from day 11 to day 16. On day 17, cells were treated with Accutase® (STEMCELL Technologies) and seeded and fed with neuronal maturation medium (STEMCELL Technologies, #08510) till days 22–24.
Growth protocol H7/WA07 (WiCell) and H9/WA09 cells (WiCell) were grown on Matrigel with reduced growth factors (ThermoFisher Scientific, #354230) in mTeSR1 medium (STEMCELL Technologies, #85850) at 37°C and 5% CO2. For neural differentiation, ES cells were seeded onto AggreWell800 plates (STEMCELL Technologies, #34811) and fed with neural induction medium (STEMCELL Technologies, #05835) to form uni-sized embryoid bodies (EBs).
Extracted molecule genomic DNA
Extraction protocol Cells were harvested in PBS. Cytoplasmic fractions were extracted using buffer A with 1× protease inhibitors and 1 mM DTT. Nuclear pellets were cross-linked by 1.1% formaldehyde in buffer B with 1× protease inhibitors and 1 mM DTT; washed; and lysed in lysis buffer 3 with 1× protease inhibitors, 1 mM DTT, and 1 mM PMSF. The fixed and lysed nuclear extract was sonicated with Bioruptor® Pico (Diagenode) 10 times for 15 s each, with 45-s intervals. Chromatin was added to Dynabeads™ (Life Technologies) prebound with 4 μg of antibodies. For UTX chromatin immunoprecipitation (ChIP), chromatin and antibodies were incubated overnight, followed by 4 h of recapture with Dynabeads™ the next day.
After incubation, beads were washed and immunoprecipitates were eluted. DNA from eluates was recovered by the GeneJET FFPE DNA purification kit (ThermoFisher Scientific, #K0882).Libraries are prepared and sequenced at the St. Jude Hartwell Center.

Description H3K4me3-AB2-hNSC-H7-WT.hg19.narrowPeak.gz
Data processing Basecalls performed using CASAVA
Single-end reads of 50bp were mapped human genome hg19(GRCh37-lite) by BWA (version 0.7.12-r1039, default parameter), duplicated reads were then marked with Picard(version 2.6.0-SNAPSHOT) and only non-duplicated reads have been kept by samtools (parameter “-q 1 -F 1024” version 1.2).
We followed ENCODE guideline for quality control of our data. For peak calling of H3K27ac, H3K4me3, we used MACS2(version 2.1.1.20160309). To assure the replicability, we first finalized reproducible peaks for each group as only retained a peak if it called with stringent cutoff(macs2 -q 0.05) in one sample and at least called with lower cutoff(macs2 -q 0.5) in the other sample. Peaks for H3K27me3 were called by reproducible peaks between SICER(V1.1) and MACS2. Correlation plots indicated the libraries are reproducible between biological replicates.
