(Submitter supplied) In order to comprehensively define the epigenetic patterns specific to MPNST, we generated profiles for 6 histone modification marks, including H3K4me1 (enhancer), H3K27Ac (active enhancer), H3K9me3 (heterochromatin), H3K27me3 (polycomb repression), H3K79me2 (transcription) and H3K4me3 (promoter). Systematic epigenomic profiling of chromatin states in MPNST cells revealed epigenetic subtypes in MPNST based on Polycomb related repressive and bivalent chromatin states. more...

(Submitter supplied) 7 MPNSTs from 7 neurofibromatosis-type 1 patients were screened with a high resolution array-CGH. Each MPNST DNA (somatic tumor DNA) was individually hybridized on Agilent whole human genome 244K microarrays (Platform GPL4091) using the pooled genomic constitutional DNA (lymphocytes DNA) from the normal control patients as reference, in order to detect tumor-specific aberrations.

(Submitter supplied) The SWI/SNF-family chromatin remodeling protein ATRX is a tumor suppressor in sarcomas, gliomas and other malignancies. Its loss of function facilitates the alternative lengthening of telomeres (ALT) pathway in tumor cells, while it also affects Polycomb repressive complex 2 (PRC2) silencing of its target genes. To further define the role of inactivating ATRX mutations in carcinogenesis, we knocked out atrx in our previously published p53/nf1-deficient zebrafish line that develops malignant peripheral nerve sheath tumors and gliomas. more...

(Submitter supplied) The polycomb repressive complex 2 (PRC2) exerts oncogenic effects in many tumour types1. However, loss-of-function mutations in PRC2 components occur in a subset of haematopoietic malignancies, sug- gesting that this complex plays a dichotomous and poorly understood role in cancer2,3. Here we provide genomic, cellular, and mouse mod- elling data demonstrating that the polycomb group gene SUZ12 func- tions as tumour suppressor in PNS tumours, high-grade gliomas and melanomas by cooperating with mutations in NF1. more...

(Submitter supplied) Diffuse Intrinsic Pontine Glioma (DIPG) is a universally fatal childhood brain tumour which frequently carries a mutation in genes encoding histone H3. These mutations lead to a lysine-to-methionine (K-to-M) substitution at position 27 (H3K27M) within the histone H3 tail and initiate global shifts in the abundance of Polycomb Repressive Complex 2 (PRC2) mediated H3K27 methylation (me) and P300/CBP mediated acetylation (ac). more...

(Submitter supplied) Using RNA-seq we characterized gene expression changes occuring upon knockout of EZH2, EZH1, EZH1+EZH2 or SUZ12 in a neurofibroma cell line. We also investigated the transcriptional consequences of EZH1+EZH2 double knockout in a SUZ12-mutant MPNST cell line.

(Submitter supplied) Genetic alterations that result in the dysregulation of polycomb repressive complex 2 (PRC2) are common features of multiple cancer types. Loss-of-function mutations in the PRC2 genes, SUZ12 or EED, occur at high frequency in malignant peripheral nerve sheath tumors (MPNST), a clinically aggressive sarcoma that arises from NF1-deficient Schwann cells. To define the oncogenic mechanisms mediated by PRC2 loss, we used engineered MPNST model systems that dynamically reassemble a competent PRC2 coupled with single cell sequencing from clinical samples to evaluate the transcriptomic and epigenetic consequences of PRC2 loss. more...

(Submitter supplied) To investigate the function of p53 in regulating response to MET inhibition in MPNST cells we established NF1-MET;sgP53 cells in which Trp53 was knocked out using CRISPR-Cas9. As a control, the parental NF1-MET was transduced with CRISPR-Cas9 in the absence of sgRNA. We then performed gene expression profiling analysis using data obtained from RNA-seq of the 2 different cells treated with either capmatinib or vehicle in duplicate.
