Sample GSM2442786 Query DataSets for GSM2442786
Status Public on Dec 31, 2016
Title H3K4me2
Sample type SRA
 
Source name Human Endothlial cell line
Organism Homo sapiens
Characteristics cell type: Primary Human Umbilical Vein Endothelial Cells
passages: P3-6
antibody: H3K4me2, abcam ab32356
Treatment protocol 50ng/ml VEGFa was used to treat serum-starved HUVEC cells. For modified RNA experiments, 0.5ug/ml modified RNA expressing GFP and ETS1 was used. For siRNA experiment, 10ng/ml siRNA was used.
Growth protocol Primary HUVEC cells purchased from Lonza within 3-6 passages were grown in EBM2+1% FBS or EGM2 medium (Lonza)
Extracted molecule genomic DNA
Extraction protocol ChiP-seq: Chromatin DNA was extracted from sonicated nuclei and further selectively accumulated by ChiP-specific antibody. RNA-seq: total RNA were purified by Qiagen RNeasy column.
Illumina multiplex library protocol for ChiP-seq and mRNA seq of VEGF stimualtion is as described (Bing Zhang, et al. , 2013,Genome Res. 2013 Jun;23(6):917-27); Spike-in mRNA-seq protocol followed ScriptSeq v2 RNA-seq kit (Illumina)
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 2500
 
Description H3K4me2 ChiP-seq after VEGF stimulation for 0h
Data processing ChIP-seq reads were aligned to the hg19 human genome assembly using bowtie2 with the following configurations: -p 8 -M 1
ChiP-seq Peaks were called using MACS with the following setting: -f BAM -g 2.45e9, and differential peaks were calculated using bdgdiff module in MACS.
The reads density was calculated using Homer and displayed in tag heat map using JAVA Tree.
RNA-seq reads were aligned to the hg19-ERCC genome assembly (contains hg19 and ERCC sequences ) using tophat2 with the following configurations: -p 4.
Fragments Per Kilobase of transcript per Million mapped reads (FPKM) were calculated using a protocol from Trapnell, Cole, et al. , Nature protocols 7.3 (2012): 562-578. In short, cufflinks was used for transcript assembly, cuffmerge for assemblies merge, cuffdiff for differnetial analysis and CummeRbund for the following analysis.
