Sample GSM8087442 Query DataSets for GSM8087442
Status Public on Sep 27, 2024
Title 7048
Sample type SRA
 
Source name Blood
Organism Bos taurus
Characteristics tissue: Blood
cell type: Blood
genotype: MRG
Growth protocol The cows were raised in the same conditions on the farm
Extracted molecule genomic DNA
Extraction protocol One mL of blood was sent to the Génome Québec sequencing platform for DNA extraction
DNA conversion step involves in three primary enzymes: TET2 and T4-BGT detect and transform 5mC and 5hmC into a product that cannot be deaminated by the APOBEC3A enzyme. Subsequently, APOBEC3A deaminates unmodified cytosines by converting them to uracils. As a result, unmethylated cytosines are transformed into uracils and then to thymines during PCR amplification, while methylated cytosines remain as cytosines
 
Library strategy OTHER
Library source genomic
Library selection other
Instrument model Illumina NovaSeq 6000
 
Data processing Reads were filtered, trimmed, and deduplicated using fastp version 0.23.1 with default parameters
Read conversion, alignment to the Bos taurus reference genome (ARS-UCD1.2.104)
Methyl calling were performed using Bismark. This process was implemented in the DRAGEN Methylation Pipeline, which was run on an Illumina DRAGEN server using default parameters
Methylation calls from Bismark were filtered to retain CpG sites covered by at least six reads in a minimum of five samples per group.
The annotation was performed using the annotatePeak function in the default mode of the R ChIPseeker (version 1.32.1).
Assembly: ARS-UCD1.2
Supplementary files format and content: A tab-delimited text file includes information about differential methylated positions with q-values less than 0.01 and methylation differences greater than the absolute value of 25 and their annotations.
Supplementary files format and content: A tab-delimited text file includes information about differential methylated regionss with q-values less than 0.01 and methylation differences greater than the absolute value of 25 and their annotations. The regional analysis used a 500-bp sliding window with a 250-bp overlap and a minimum of five CpG per regions
Library strategy: Enzymatic methyl-seq (EM-seq)
