| Source name |
cardiomyocyte
|
| Organism |
Mus musculus |
| Characteristics |
strain: C57BL/6J
chip antibody: anti-H3K9me2; Abcam (ab1220)
treatment: transverse aortic constriction (TAC) for 1 week

| Extracted molecule |
genomic DNA |
| Extraction protocol |
ChIP was performed as described elsewhere (Peters AH, et al. (2003) Mol Cell 12(6):1577–1589).
The Libraries were generated using NuGEN Ovation Ultralow System V2 1–96 kit.
ChIP-seq libraries were produced from as little as 1 ng of double-stranded DNA. The workflow is consisted of three steps: end repair to generate blunt ends, adaptor ligation with optional multiplexing and PCR amplification to produce the final library.

| Data processing |
ChIP-seq reads were aligned to the mm10 genome assembly using bwa mem v0.7.10-r789 (PMID:19451168)
Reads with mapping quality ≤ 10 and not properly paired were removed with samtools (v1.1)
Differential peak calling was detected using THOR v0.1 (PMID: 27484474). The Input DNA signal was subtracted from each ChIP-seq signal. Differential peaks were filtered by adjusted pValue<= 0.01.
Blacklisted regions identified by the ENCODE project (The ENCODE Project Consortium, 2012) were discarded during differential peaks detection and bigwig profile creation.
Genome_build: mm10 (GRCm38)
Supplementary_files_format_and_content: *.bw: the genomic distribution of ChIP-seq signal subtracted from the input DNA. These profiles were obtained using deeptools2 (PMID: 27079975) and these paramaters: -bs 10 --smoothLength 50 --ratio subtract --normalizeUsingRPKM.
