Study Description

Genomic sequencing has driven precision-based oncology therapy; however, genetic drivers remain unknown or non-targetable for many malignancies, demanding alternative approaches to identify therapeutic leads. Ependymomas are chemotherapy-resistant brain tumours, which, despite genomic sequencing, lack effective molecular targets. Here, we mapped active chromatin landscapes in 42 primary ependymomas in two non-overlapping primary ependymoma cohorts. Enhancer regions revealed novel oncogenes, molecular targets, and pathways, which when subjected to small molecule inhibitor or shRNA treatment, increased survival and slowed proliferation in mouse and neurosphere patient-derived models of ependymomas. This study represents one of the largest enhancer mapping study of any cancer type to date, and provides a framework for target and drug discovery for other cancers recalcitrant to therapeutic development because of their lack of known genetic drivers.

Dataset ID Description Technology Samples
EGAD00001003940
This dataset contains whole genome sequencing data from 24 patients. For each patient a tumour and control sample has been sequenced on a Illumina HiSeq2000 instrument in paired-end mode. Up to three lanes per sample have been sequenced resulting in 112 Fastq files.
Illumina HiSeq 2000 48
EGAD00001003966
This dataset conatains RNA sequencing data from 24 patients. Up to two lanes per tumour sample have been seqeunced on a Illumina HiSeq2000 instrument in paired-end mode resulting in 58 Fastq files.
Illumina HiSeq 2000 24
EGAD00001003973
This dataset contains whole exome sequencing data from 24 patients. The Agilent SureSelect Human All Exon 50-Mb target enrichment kit was used to capture all human exons for deep sequencing. For each patient a tumour and control sample has been sequenced on a Illumina HiSeq2000 instrument in paired-end mode. Up to three lanes per sample have been sequenced resulting in 118 Fastq files.
Illumina HiSeq 2000 48
EGAD00001003979
This dataset contains ChIP sequencing data from 24 patients. ChIP of 5–10 mg flash-frozen primary ependymoma tumour was performed using 5 mg H3K27ac antibody per ChIP experiment. The enriched DNA has been sequenced on a Illumina HiSeq2000 instrument in paired-end mode. Up to two lanes per sample have been sequenced resulting in 70 Fastq files.
Illumina HiSeq 2000 24
