Sample GSM5671189 Query DataSets for GSM5671189
Status Public on Nov 29, 2022
Title G1s-C1-26_RNA
Sample type SRA
 
Source name K562, G1s C1 #26
Organism Homo sapiens
Characteristics cell line: K562
genotype: mutant
Growth protocol K562 cells were cultured with RPMI1640 (Sigma-Aldrich) containing 10% heat inactivated fetal bovine serum (FBS) at 37°C in 5% CO2 atmosphere.
Extracted molecule total RNA
Extraction protocol Chromatin samples were extracted using SimpleChIP Enzymatic Chromatin IP Kit (CST) according to the protocol. For ChIP reactions, Dynabeads anti-rabbit IgG (Thermo Fisher Scientific) was used to reduce noise instead of the Protein G magnetic beads included in the kit. CUT&RUN assay was performed using CUT&RUN Assay Kit (CST), and samples were purified using Monarch PCR & DNA Cleanup Kit (NEB). total RNA was extracted using the RNeasy plus mini kit (Qiagen).
ChIP-seq and CUT&RUN libraries were prepared using KAPA HyperPrep Kit (KAPA Biosystems). Total RNA was purified by NEBNext Poly(A) mRNA Magnetic Isolation Module (NEB), and RNA-seq library was prepared by KAPA RNA Hyper prep kit (KAPA Biosystems).
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model NextSeq 550
 
Data processing For ChIP-seq data,sequence reads were aligned to genome by Bowtie2 (ver 2.2.2) with option -N1. For CUT&RUN-seq data, reads were aligned according to the method by Skene and Heinikoff (Nature Protocols 2018 13, 1006-1019). For RNA-seq data, sequence reads were aligned to genome using STAR (ver 2.6.1d). Aligned reads were counted by RSEM (ver 1.3.1). The count data normalized using the DESeq2 package (ver 1.32.0).
Duplicated reads of ChIP-seq and CUT&RUN-seq were removed by Picard (ver. 2.18).
The BAM files of ChIP-seq and CUT&RUN data were converted to bigWig coverage files using bamCoverage command of deepTools (ver 3.1.3). Read coverages were normalized to Read per genomic content (RPGC). For the GATA1 and GATA2 ChIP-seq data, peak call was performed using HOMER (ver 4.11) with default settings.
Genome_build: hg19 (ChIP-seq, CUT&RUN-seq), hg38 (RNA-seq)
Supplementary_files_format_and_content: bigWig files normalized in reads per genomic content (RPGC) and bed files.
