All of the animal experiments were conducted using protocols approved by the Institutional Animal Care and Use Committees of Fred Hutchinson Cancer Research Center, protocol 50842. Ntva-Ink4a/Arf+/- and Ntva-Ink4a/Arf-/- mice were used to generate mouse gliomas. The genetic backgrounds of tva mice are FVB/N, C57BL6, BALB/C, and 129. To generate mCherry and HoxA5-expressing mouse gliomas, we used the RCAS/tva system. Briefly, DF1 cells were maintained with 10% fetal bovine serum (FBS) in Dulbecco's Modified Eagle Medium (DMEM). Chicken fibroblasts were transfected with each RCAS viral plasmid using Fugene 6 Transfection reagent (Roche) following the manufacturer’s protocol. Then, PDGFb-expressing DF1 cells were mixed with either mCherry- or HoxA5-expressing DF1 cells. This mixture of DF1 cells was injected to Ntva-Ink4a/Arf+/- and Ntva- Ink4a/Arf-/- mice. Adult mice anesthetized with isoflurane were positioned in a stereotactic device (Stoelting, Wood Dale, IL). RCAS transfected DF1 cells were injected using a 30-gauge needle inserted into the right frontal cortex (coordinates: anterior to bregma 1.5 mm, lateral 0.5 mm, and a depth 1.5 mm). Then, mice were monitored daily until they developed signs of illness, such as lethargy, poor grooming, weight loss, dehydration, macrocephaly, seizure, jumping and paralysis.
