RNA Sequencing of murine MPNST Tumors

We utilized three murine MPNST cell lines. 67C-4 and #5NPCIS cell lines are derived from spontaneously arising tumors in mice mutated for NF1 and p53 (so-called NP-cis mice; PMID: 12154062). SN4-4 cells originated from MPNST tumors induced by injecting adenovirus containing Cas9 and guide RNA for Nf1 and p53 into the sciatic nerves, resulting in NF1/p53-null MPNST (PMID: 32456131). We implanted 5 x 10^6 murine MPNST cells, subcutaneously, into the flanks of 6-8 weeks old gender-matched C57BL/6 mice (for 67C-4 and #5NPCIS) and BALB/c mice (for SN4-4 mice) to generate MPNST tumors. All mice were procured from Envigo. Upon reaching a size of 300-500 mm3, the mice were euthanized to harvest the tumors, which were subsequently flash frozen using liquid nitrogen and processed for RNA sequencing.
