Sample GSM7923061 Query DataSets for GSM7923061
Status Public on Dec 02, 2023
Title RORA_H3K27me3_1
Sample type SRA
 
Source name limbal stem cells
Organism Homo sapiens
Characteristics cell type: primary limbal stem cells
treatment: RORA overexpression
chip antibody: H3K27me3
Treatment protocol Cells were infected with lentiviruses expressing target genes.
Growth protocol LSCs were grown in DMEM/F-12 (1:1) medium containing 1% penicillin/streptomycin, 10% fetal bovine serum, 10 ng/ml EGF, 5 μg/ml insulin, 0.4 μg/ml hydrocortisone, 0.1 nM cholera toxin and 2 nM 3,3',5-triiodo-L-thyronine.
Extracted molecule genomic DNA
Extraction protocol chromatin was fixed with 1% formaldehyde for 10 min and sheared in a sonification buffer. Fragmented DNA was incubated with primary antibodies overnight at 4℃ and then with Protein A/G Dynabeads for 1 h. The beads were collected and washed sequentially with the following solutions: high-salt buffer, low-salt wash buffer, and TE buffer. Elution of the immunoprecipitated protein/DNA complexes was performed using elution buffer at 65℃ for 4 h. Next, the protein/DNA complexes were incubated with proteinase K (Invitrogen) and RNase A (Invitrogen) for 1 h. De-crosslinked DNA was purified using the PCR Purification Kit (Qiagen).
ChIP-seq DNA libraries were generated using VAHTS Universal DNA Library Prep Kit for Illumina V3 (Vazyme) according to the manufacturer’s instructions.
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina NovaSeq 6000
 
Description RORA_OE_H3K27me3_differential_peaks.xlsx
Data processing Reads were trimmed by trimmomatic tool and then aligned to human hg19 reference genome using BWA software.
Duplicated reads were removed by Picard Markduplicates and only uniquely mapping reads were retained for further analysis.
MACS2 was used to call peak.
Assembly: hg19
Supplementary files format and content: Excel files containing differential H3K27ac, H3K4me3 and H3K27me3 peaks between control and RORA-overexpression groups. A BED file containing RORA binding sites in RORA-overexpressed LSCs.
