| Title |
H3K27ac_T16_rep1 |
| Sample type |
SRA |
| |
|
| Source name |
Human primary adipose stem cells
|
| Organism |
Homo sapiens |
| Characteristics |
time point: 16 Hours (T16)
cell type: ASCs on 16 hours after adipogenic induction
chip antibody: anti-H3K27ac antibody (Diagenode c15410174), at 2.5 microgram per 10e6 cells
replicate: Rep1
|
| Treatment protocol |
Proliferating cells were harvested, re-seeded at confluency and cultured confluent for 48 h without fibroblast growth factor. At T00, ASCs were induced to differentiate with 10 µg/ml insulin, 200 µM indomethacin, 1µM dexamethasone and 0.5 µM 3-isobutyl-1-methylxanthine. Cells were collected at indicated timepoints for protein, RNA and chromatin preparations and analyses.
|
| Growth protocol |
Human normal ASCs purifed from adipose tissue were cultured in proliferating state in DMEM/F12 containing 10 % fetal calf serum and 20 ng/ml basic fibroblast growth factor.
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
For ChIP, cells were sonicated to produce chromatin fragments of ~200 base-pairs, lysates were clarified by sedimentation and histone-DNA or Lamin-DNA complexes were isolated from supernatants by ChIP using specific antibodies. RNA was purified from cell lysates using the RNEasy mini kit (Qiagen).
ChIP-seq and RNA-seq sequencing libraries were prepared according to Illumina protocols for sequencing on a Nextseq500 or Novaseq (ChIP-seq) or on a Nextseq500 (RNA-seq) at the Norwegian Sequencing Center.

| Description |
H3K27ac_T16_rep1_3-3.fastq.gz
|
| Data processing |
ChIP-seq and RNAseq reads were aligned to the hg38 reference genome using bowtie2 version 2.4.1 for ChIP-seq reads and BWA-MEM version 0.7.12 for RNAseq reads
Duplicate reads were removed using picard MarkDuplicates
For RNA-seq, reads per transcript were counted using featureCounts from Subread package 2.0.1. Differential gene expression was determined using DESeq2 1.30.0.
For histone modification ChIPseq, H3K4me1 peaks were called from both replicated using macs2 2.2.7.1 .
For LMNB1 ChIPseq, Peak calling was done using Enriched Domain Detector (EDD) version 1.1.15, run 10 times on each sample to optimize BinSize and GapPenalty settings.
