Sample GSM7856786 Query DataSets for GSM7856786
Status Public on Sep 29, 2024
Title MB3662-hic
Sample type SRA
 
Source name brain
Organism Homo sapiens
Characteristics tissue: brain
Sex: M
disease: medulloblastoma
disease subgroup: SHH
Treatment protocol None
Growth protocol The majority of samples were uncultured, primary patient tissue. The brain tissue culture was grown as described previously (Michealraj et al. Cell. 2020; PMID: 32445698).
Extracted molecule genomic DNA
Extraction protocol Approximately 2.5M cells were used for In-situ Hi-C library approach (Rao et al. Cell. 2014; PMID: 25497547) with library preparation performed as described previously (Johnston et al. Genome Research. PMID: 31249064). Hi-C libraries were sequenced at 150 bp PE with a Hi-Seq X instrument (Illumina) at McGill Genome Centre (Montreal, QC).
In-situ Hi-C
Kapa RNA HyperPrep kit prepared and sequenced at Ontario Institute for Cancer Research (OICR)
Paired-end, stranded RNA-Seq
 
Library strategy Hi-C
Library source genomic
Library selection other
Instrument model HiSeq X Ten
 
Data processing Fastqs were processed to hic files using Juicer v1.6.
Contact domains were annotated from hic files using Arrowhead from Juicer Tools v1.19.02 with parameters ‘--ignore-sparsity -k SCALE’ for the following data resolutions (kb): 10, 25, 50, 100.
Loops were annotated from hic files using HiCCUPS from Juicer Tools v1.19.02 with parameters ‘--cpu -m 4096 --ignore-sparsity -k SCALE’ for resolutions (kb): 10, 25.
Compartments were annotated from hic files using the leading eigenvectors of the Juicer Tools Pearsons with parameters ‘SCALE BP 50000 -p’
Boundary scores were annotated from 50-kb contact matrices using Robustad v1.0
RNA-seq alignment: reads aligned to hg38 (GCA_000001405.15_GRCh38_no_alt_plus_hs38d1_analysis_set) using HISAT2 (v2.1.0) with parameters ‘--rna-strandness RF --downstream-transcriptome-assembly’
RNA-Seq quantification: SAM output was sorted, converted to BAM, and indexed using samtools (v1.9). A counts table was prepared using the count function of HTSeq (v0.13).
RNA-Seq differential expression testing: Limma with Voom transformation (v3.44)
RNA-Seq coverage: BigWig tracks were generated using DeepTools bamCoverage with parameters --effectiveGenomeSize 2913022398 --normalizeUsing RPGC --binSize 1. Separate files for positive and negative strand were generated with parameters --filterRNAstrand "forward" or --filterRNAstrand "reverse"
Assembly: hg38, GCA_000001405.15_GRCh38_no_alt_plus_hs38d1_analysis_set
