Sample GSM7762101 Query DataSets for GSM7762101
Status Public on Sep 05, 2023
Title TRP2, +met, MeDIP, 2hr, 256X, rep1
Sample type SRA
 
Source name yLB121a-TRP2
Organism Saccharomyces cerevisiae
Characteristics strain: yLB121a-TRP2
chip antibody: anti-5-methylcytosine(Thermo Fisher, 33D3)
condition: 2hr, 2nM Beta-estradiol
genotype: MATa, his3-11,15, leu2-3,112, trp1-1, ura3-1, can1-100, ade2-1, ADH1::2xlexO-GAL1corepr-LacI-SV40NLS-M.CviPI:ADH1pr-LexA-ERHBD-VP16AD::LEU2, TRP2::256XLacO::HIS3
Treatment protocol β-estradiol (Sigma, 50-28-2) was added to a final concentration of 2 nM for 1/2 hrs, allowing the LacI-NLS-M.CviPI fusion protein to express. For MATa and MATalpha viewpoint, glucose (D) or galactose(G) was added according to the experimental conditions.
Growth protocol Yeast strains were grown in 50 mL synthetic media with/without methionine at 30°C to OD660 = 0.3.
Extracted molecule genomic DNA
Extraction protocol Standard MeDIP protocol for preparation of methylated genomic DNA
MeDIP-Seq libraries were prepared with NEBNext Ultra II DNA Library Prep Kit (NEB, E7645L). Next generation sequencing was performed on NextSeq 2000 (Illumina).
 
Library strategy OTHER
Library source genomic
Library selection other
Instrument model NextSeq 2000
 
Description Deseq2_output.xlsx
Data processing Paired-end reads of 50 bp or 150 bp were processed with fastp (version 0.23.2) to remove low quality reads. Processed reads were aligned to S. cerevisiae genome (sacCer3) with BWA (version 0.7.17). Aligned bam files were deduplicated with Picard MarkDuplicates (version 3.0.0). bigwig files were generated by deeptools bamCoverage (version 3.5.1) for visualization purposes. To detect differentially methylated NDRs, aligned reads on each NDR were counted by Subread featureCounts (version 2.0.3) using a list of NDR coordinates generated from a previous study, with the following parameters “-p -O”. Fold change and P-value were generated by DEseq2 (1.38.0) without outliers filtering. log2 (Fold Change) > 0.7 and the adjusted P-value < 0.05 were used as the cutoff for identifying differentially methylated regions.
