ChIP-seq dataset for epigenomic landscape of MPNST

ABSTRACT: 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. We demonstrate that PRC2 loss led to de-repression and subsequent enhancer reprogramming at key neural crest specifiers aiding the acquisition of this de-differentiated aggressive tumor phenotype.

Genomic characterization of the MPNST

Project description:Malignant peripheral nerve sheath tumor (MPNST) is a rare sarcoma that lacks effective therapeutic strategies. By characterizing recurrent gene copy number aberrations, we gain insight into the most altered pathways with the purpose of scanning possible therapeutic targets. We conducted a microarray-based comparative genomic hybridization profiling of two cohorts of primary MPNST tissue samples including 25 patients treated at The University of Texas MD Anderson Cancer Center and 26 patients from Tianjin Cancer Hospital. All samples had at least 90% tumor content. Commercially available normal genomic DNAs were used as control.

Malignant peripheral nerve sheath tumor (MPNST) and MPNST-like entities defined by DNA methylation profile in pediatric and juvenile population

Project description:The diagnosis of Malignant peripheral nerve sheath tumors (MPNSTs) can be challenging, but is aided by their characteristic DNA methylation profile (DMP). An MPNST-like group, characterized by retained H3K27me3 expression, was recently recognized. To evaluate the diagnostic usefulness of DMP in pediatric/juvenile MPNSTs, we selected pediatric/juvenile malignancies from the Bambino Gesù Children's Hospital DMP database. DMP revealed unexpected molecular heterogeneity in histologically homogenous MPNSTs/Atypical neurofibromas, while samples with MPNST-like DMP manifested histological diversity. In conclusion, DMP is useful in diagnosing MPNST, discriminating morphologic mimics classified as MPNST in premolecular era, and investigating the MPNST-like ‘hybrid’ group in pediatrics.

Stem-like cells drive NF1-associated MPNST functional heterogeneity and tumor progression

Project description:NF1-associated malignant peripheral nerve sheath tumors (MPNST) are the major cause of mortality in neurofibromatosis. MPNST arise from benign peripheral nerve plexiform neurofibromas (PN) which originate in the embryonic neural crest cell lineage. Using reporter transgenes that label early neural crest lineage cells in multiple NF1 MPNST mouse models, we discovered and characterized a rare MPNST cell population with stem cell-like properties that is essential for tumor initiation and relapse. Following isolation of these cells we derive a cancer stem cell specific gene expression signature that includes consensus embryonic neural crest genes and we also identify Nestin as a novel marker for the MPNST cell of origin. Finally, application of the mouse cancer stem cell signature to single cell sequencing data from a rare NF1-associated MPNST precursors called atypical neurofibromatosis neoplasms of uncertain biologic potential (ANNUBP), identifies preformed unsupervised gene expression cell clusters. Enrichment of the cancer stem cell signature in cognate human tumors supports the generality and relevance of cancer stem cells to therapy development.
