| Sample type |
SRA |
| |
|
| Source name |
Trp53 R172H/R172H mouse
|
| Organism |
Mus musculus |
| Characteristics |
p53 mutation status: Trp53 R172H/R172H
treatment: Untreated
antibody: H3K4me3 Abcam (ab8580)
|
| Treatment protocol |
As indicated in the SAMPLES section
|
| Growth protocol |
All cells were grown in DMEM with 10% FBS, at 3% oxygen.
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
For ChIP-seq, cells were crosslinked with formaldehyde (1% final) for 10min at room temperature, and harvested for sonication. Nuclei were extracted and chromatin was sheared to an average size of 200bp using a Covaris S220 sonicator
For RNA-seq, polyA+ RNA was isolated by two rounds of polyA selection using the Life Technologies mRNADirect kit per manufacturer's recommendations.
Sequencing libraries for ChIP-seq were constructed using the NEBNext Ultra kit as per manufacturer's recommended instructions. Sequencing libraries for polyA+, stranded-RNA-seq were constructed using the NEBnext Ultra Directional RNAseq kit as per manufacturer's recommended instructions.

| Description |
ChIPseq for H3K4me3 in primary p53 R172H Knock-in MEFs
|
| Data processing |
Raw fastq files were aligned to mm9 using Bowtie2, allowing for only uniquely aligned reads to be reported.
bowtie2 -N1 -k1 mm9
Uniquely mapped reads were processed into HOMER TagDirectories (makeTagDirectory <file> <TagDir_file>)
Bedgraphs were then generated using the command 'makeUCSCfile <ChIP_TagDirectory> -o auto'
Expression values (FPKM) for RNAseq experiments were derived using HOMER (analyzeRepeats.pl mm9 -condenseGene)
genome build:mm9
processed data files format and content: Text file (of FPKM expression values from RNAseq)
processed data files format and content: BedGraph files (from HOMER, for visualization in UCSC)
