Sample GSM4818345 Query DataSets for GSM4818345
Status Public on Oct 07, 2020
Title ATAC-seq KD_HBVneg_rep1
Sample type SRA
 
Source name KD_HBVneg_rep1
Organism Homo sapiens
Characteristics cell line: HepG2
gender: male
age: 15 yr
passage: 20-23
tissue: Liver
genotype/variation: KD
Growth protocol Cells were cultured for 10 days. Media was changed every 3 days and passaged if cells were confluent.
Extracted molecule genomic DNA
Extraction protocol Cells (5 x 104) were washed in cold PBS and lysed in 50 µl of lysis buffer (10 mM Tris HCl pH 7.5, 10 mM NaCl, 3 mM MgCl2, 0.1% IGEPAL CA-630). Following lysis and centrifugation, nuclei were used for transposition using Illumina Tagment DNA TDE1 Enzyme and Buffer Kit (Cat# 20034197) per manufacturer’s protocol. The transposed DNA was cleaned using Qiagen Reaction Cleanup kit (Cat# 28204), eluted in 10 µL elution buffer and stored at -20oC.
Transposed DNA was PCR amplified using primers containing unique adapters. Amplified library was purified using Qiagen MinElute PCR Purification Kit (Cat#28004). Pairedend 2x50 bp sequencing was performed using a HiSeq2500 system (Illumina).

Description HepAD38 -HBV DDX5KD
Data processing Data quality control was performed using FastQC v0.11.8. Raw sequencing reads were mapped to hg19 using bowtie2.3.4.3 [2] with “-X 2000”.
All other parameters were kept as default. Duplicate and low quality (MAPQ<30) reads are removed using PicardTools2.21.6
Differential chromatin accessible regions/peaks between DDX5 WT and KD were obtained using MACS2.1.2, peaks overlapped with the hg19 blacklist(wgEncodeDacMapabilityConsensusExcludable.bed) are removed
HOMER4.9.1 was used to annotate the peaks with their adjacent genes that were then subjected to pathway analysis against all biological processes from gene ontology (GO) using Matescape
The IGV tracks were made using bamCoverage from DeepTools3.3.0 with parameter “-p 3 -bs 5 --normalizeUsing CPM -- ignoreDuplicates” and visualized by IGV browser
