| Title |
SMI-Rep 1 |
| Sample type |
SRA |
| |
|
| Source name |
iSLK-BAC16 (WT)
|
| Organisms |
Homo sapiens; Human gammaherpesvirus 8 |
| Characteristics |
cell type: iSLK cells
virus: BAC16 infectious clone
treatment: 1mM Sodium butyrate + 1 ug/mL doxycycline (24hr)
eclip antibody: No antibody (size-matched input)
|
| Treatment protocol |
Cells were treated with 400mJ/cm2
|
| Growth protocol |
iSLK-BAC16 (WT) cells were grown in DMEM supplemented with 10% Tet-free FBS. Cells at ~70% confluency were treated with 1mM sodium butyrate and 1 ug/mL doxycycline for 24 hours. Twenty million cells were harveested per sample.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Cells were lysed with eCLIP lysis buffer (Eclipse Bio) at 20 million cells/ml, snap frozen in liquid nitrogen, and sent to Eclips Bio where the immunoprecipitation, library prep, and sequencing were performed. All folowed the methodology of van Nostrand et al. (2016; Nature Methods)
This was performed by a third party, Eclipse Bio. No modifications were made to the protocol of Van Nostrand et al (2016; Nature Methods).

UMIs were removed using umi_tools v0.5.1: umi_tools extract –-stdin=045IP13_S37.fastq.gz --bc-pattern=NNNNNNNNNN --log=045IP13_S37.processed.log --stdout 045IP13_S37.demultiplex.fastq.gz
Read quality was checked with Fast QC v.0.11.9: fastqc 045IP13_S37.demultiplex.fastq.gz
Reads were trimmed using two rounds of Cutadapt v3.2 to trim 3´ adaptors and to control for double ligation events: cutadapt --match-read-wildcards --times 1 -e 0.1 -O 1 --quality-cutoff 6 -m 18 -a AGATCGGAAGAGCAC -a GATCGGAAGAGCACA -a ATCGGAAGAGCACAC -a TCGGAAGAGCACACG -a CGGAAGAGCACACGT -a GGAAGAGCACACGTC -a GAAGAGCACACGTCT -a AAGAGCACACGTCTG -a AGAGCACACGTCTGA -a GAGCACACGTCTGAA -a AGCACACGTCTGAAC -a GCACACGTCTGAACT -a CACACGTCTGAACTC -a ACACGTCTGAACTCC -a CACGTCTGAACTCCA -a ACGTCTGAACTCCAG -a CGTCTGAACTCCAGT -a GTCTGAACTCCAGTC -a TCTGAACTCCAGTCA -a CTGAACTCCAGTCAC -o 045IP13_S37.adapterTrim.fastq.gz 045IP13_S37.demultiplex.fastq.gz > 045IP13_S37.adapterTrim.metrics and cutadapt --match-read-wildcards --times 1 -e 0.1 -O 5 --quality-cutoff 6 -m 18 -a AGATCGGAAGAGCAC -a GATCGGAAGAGCACA -a ATCGGAAGAGCACAC -a TCGGAAGAGCACACG -a CGGAAGAGCACACGT -a GGAAGAGCACACGTC -a GAAGAGCACACGTCT -a AAGAGCACACGTCTG -a AGAGCACACGTCTGA -a GAGCACACGTCTGAA -a AGCACACGTCTGAAC -a GCACACGTCTGAACT -a CACACGTCTGAACTC -a ACACGTCTGAACTCC -a CACGTCTGAACTCCA -a ACGTCTGAACTCCAG -a CGTCTGAACTCCAGT -a GTCTGAACTCCAGTC -a TCTGAACTCCAGTCA -a CTGAACTCCAGTCAC -o 045IP13_S37.adapterTrim.round2.fastq.gz 045IP13_S37.adapterTrim.fastq.gz > 045IP13_S37.adapterTrim.round2.metrics
Repetitive elements were removed using STAR v. 2.7.7a: STAR --runMode alignReads --runThreadN 8 --genomeDir repetitive_elements/genome/ --readFilesIn 045IP13_S37.adapterTrim.round2.fastq.gz --outSAMunmapped Within --outFilterMultimapNmax 30 --outFilterMultimapScoreRange --outFileNamePrefix 045IP13_S37.adapterTrim.round2.rep.bam --outSAMattributes All --readFilesCommand gunzip -c --outStd BAM_Unsorted --outSAMtype BAM Unsorted --outFilterType BySJout --outReadsUnmapped Fastx --outFilterScoreMin 10 --outSAMattrRGline ID:foo --alignEndsType EndToEnd > 045IP13_S37.adapterTrim.round2.rep.bam
Read quality after repetitive element removal was rechecked using Fast QC v. 0.11.9: fastqc 045IP13_S37.adapterTrim.round2.rep.bamUnmapped.out.mate1
Reads were mapped using STAR V2.7.7a: STAR --runMode alignReads --runThreadN 8 --genomeDir genome/ --readFilesIn 045IP13_S37.adapterTrim.round2.rep.bamUnmapped.out.mate1 --outSAMunmapped Within --outFilterMultimapNmax 1 --outFilterMultimapScoreRange 1 --outFileNamePrefix 045IP13_S37.adapterTrim.round2.rmRep.bam --outSAMattributes All --outStd BAM_Unsorted --outSAMtype BAM Unsorted --outFilterType BySJout --outReadsUnmapped Fastx --outFilterScoreMin 10 --outSAMattrRGline ID:foo --alignEndsType EndToEnd > 045IP13_S37.adapterTrim.round2.rmRep.bam
Resulting bam files were sorted and indexed using Samtools v. 1.9: samtools sort 045IP13_S37.adapterTrim.round2.rmRep.bam -o 045IP13_S37.adapterTrim.round2.rmRep.sorted.bam and samtools index 045IP13_S37.adapterTrim.round2.rmRep.sorted.bam
