Description from dbGaP: "Malignant peripheral nerve sheath tumors (MPNSTs) are a group of highly aggressive soft tissue sarcomas that may occur sporadically, in association with neurofibromatosis type I (NF1-associated), or after radiotherapy (RT-associated). We utilized comprehensive genomic approaches and identified recurrent loss-of-function somatic alterations in the Polycomb repressive complex...

Description from GEO: "We used CRISPR/Cas9-mediated knockout of PRC2 core components, Eed and generated PRC2-isogenic murine mammary tumor model (AT3, sgCon vs. sgEed ) amenable for syngeneic transplant in C57BL/6J mice. Transcriptome analysis of the explanted PRC2-wt (sgCon) and PRC2-loss (sgEed) AT3 tumors by RNA-seq demonstrated that PRC2 loss led to the upregulation of various developmental pathways,...

Description from GEO: "PRC2 loss of function occurs frequently in human MPNST. Here, we found that PRC2-loss tumors are separated from PRC2-wt ones at the transcriptome level by RNA-seq among 41 human MPNST tumor tissues." Overall design from GEO: "mRNA profiling of 41 human MPNST tumors including 15 PRC2-wt and 26 PRC2-loss tumors"

Description from GEO: "PRC2-isogenic human malignant peripheral nerve sheath tumor (MPNST) M3 cells were generated through CRISPR/Cas9-mediated knockout of the PRC2 core component, SUZ12. PRC2 loss led to not only significant increase, but also significant decrease of chromatin accessibility at 15,346 (16% of all ATAC peaks) and 20,099 genomic loci (21% of all ATAC peaks), respectively. PRC2 loss...

Description from GEO: "PRC2-isogenic human malignant peripheral nerve sheath tumor (MPNST) M3 cells were generated through CRISPR/Cas9-mediated knockout of the PRC2 core component, SUZ12. PRC2 loss leads to global loss of H3K27me3, which causes H3K27ac redistribution and also affect other histone modification, e.g., H3K36me2/3." Overall design from GEO: "PRC2-isogenic human MPNST M3 cells (sgCon,...
