Sample GSM5653351 Query DataSets for GSM5653351
Status Public on Jan 19, 2023
Title Mouse_C57BL/6xJF1_EPC_rep2 [CxJ_EPC2]
Sample type SRA
 
Source name EPC
Organism Mus musculus
Characteristics strain: F1 hybrid resulting from female C57BL/6N and male JF1/Ms mice
age: embryonic days 7.25
genotype: wild type
cell type: EPC
Sex: female
Treatment protocol E8.5 F1 hybrid rat embryos were isolated from reciprocally crossing BN/CrlCrlj (BN rat) and WKY/NCrlCrlj (WKY rat) strains. E7.25 F1 hybrid mouse embryos were isolated from reciprocally crossing C57BL/6N and JF1/Ms strains. For both rat and mouse embryos, the ectoplacental cone (EPC) was dissected from the rest of the embryo before removing the visceral endoderm. Finally, the epiblast (EB) was dissected from the extraembryonic ectoderm (ExE). Each ExE lysate was used for rapid genetic sex determination by direct PCR amplification of the Y chromosome gene using specific primers for mouse Zfy and rat Sry. Only female EBs and EPCs were subjected to whole genome bisulphite sequencing.
Extracted molecule genomic DNA
Extraction protocol Genomic DNA was extracted using AllPrep DNA/RNA Micro Kit (Qiagen) according to manufacturer’s protocols.
One hundred nanograms of genomic DNA from JF1 (female) and C57BL/6 (male) mouse hybrids were prepared for Methyl-seq (Illumina) library construction. Twenty nanograms of genomic DNA from the other mouse and rat hybrid crosses were prepared for rPBAT or tPBAT library construction.

Data processing >Sequencing reads were trimmed using Trimmomatic (v0.32) and the following parameters: SLIDINGWINDOW:3:10 MINLEN:36 ILLUMINACLIP:TruSeq2-3-PE.fa:2:30:10.
>Read pairs that survived trimming were aligned to diploid rat or mouse pseudogenomes using MEA and Bismark.
>Duplicate reads were removed and the number of methylated and unmethylated reads overlapping each CpG of the rat or mouse genome was reported. This resulted in total (allele-agnostic), maternal- and paternal-specific CpG report files.
>Replicates and reciprocal crosses were merged for visualization and analyses.
>CpGs covered by at least 5 (total) or 1 (maternal or paternal) sequencing reads were assessed for methylation levels and genome-wide tracks were sunsequently generated for visualization.
