Sample GSM2700110 Query DataSets for GSM2700110
Status Public on Jul 12, 2017
Title Hi-C PN3 zygote rep2
Sample type SRA
Source name Preimplantation embryo
Organism Mus musculus
Characteristics strain: C57BL/6N x PWK/PhJ
developmental stage: PN3 zygote
Treatment protocol Embryos were collected from C57BL/6N mice induced to superovulation by injections of 5 IU of pregnant mare’s serum gonadotrophin(Ningbo Sansheng Pharmaceutical Co, Ltd) and 5 IU of human chorionic gonadotrophin(Ningbo Sansheng Pharmaceutical Co, Ltd) 44-48 hours apart and mated to PWK males.
Extracted molecule genomic DNA
Extraction protocol After removing the zona pellucida, embryonic cells were washed with PBS and fixed with 1% formaldehyde for 10min at RT.
HiC libraries were prepared using sisHi-C similar with in situ Hi-C method developed by Rao et al.
Library strategy Hi-C
Library source genomic
Library selection other
Instrument model HiSeq X Ten
Description processed data file:
PN3_rep12_allValidPairs.txt.gz, PN3_rep12_maternal_allValidPairs.txt.gz, PN3_rep12_paternal_allValidPairs.txt.gz
Data processing Basecalls performed using CASAVA version 1.8
Hi-C reads are processed using HiCPro version2.7.1b and replicates of same stage were pooled together
Compartment analysis are done as previously described. (Dixon et al., 2015)
TAD calling is done using Insulation score method as previously described ( Crane et al., 2015)
RNA-Seq reads were aligned to the mm9 genome assembly using Tophat version 2.0.11, then replicates were merged together, and transcript abundance (FPKM) were calculated based on Refseq annotation using cufflinks version 2.0.2
Genome_build: mm9
Supplementary_files_format_and_content: The files including all the valid interaction pairs ( described as Servant et al., 2015). The valid pairs are stored using a simple tab-delimited text format ; read name / chr_reads1 / pos_reads1 / strand_reads1 / chr_reads2 / pos_reads2 / strand_reads2 / fragment_size [/ allele_specific_tag]
