Mice^[1]
Six-week old athymic female nude mice weighing about 25 g are stereotactically injected with 1 × 10⁶ U251-FM-shCTRL or shMPS1 cells, or U251-FM, or 3 × 10⁵ GBM8-FM cells (in 10 and 4 μL PBS, respectively) using a stereotactic instrument after drilling a small hole in the cranium of the mice. For the U251-FM-shRNA experiment, a minimum of 3 mice per group is used, and for the U251-FM and GBM8-FM cells, at least 5 mice per group are used. Tumor growth is monitored by Fluc bioluminescence imaging after injection of 150 μL D-luciferin (50 mg/mL) and imaging 10 min later for luciferase-mediated photon activity using the IVIS Lumina imaging system for the U251-FM model and the IVIS Spectrum for the GBM8-FM model. When tumors reach a size around 10⁷ radiance for the U251 model and 5 × 10⁵ radiance for the GBM8 model, mice are intravenously injected with vehicle, and/or 2 mg/kg MPS1-IN-3 in 20% hydroxypropyl-beta-cyclodextrin (HPbetaCD), twice/week over three weeks. Tumor volume is monitored weekly by Fluc imaging^[1].
