KIT and glioblastoma: Following a 24-h incubation of glioblastoma cells with 3 μg/mL So, either there was no change in the expression of genes encoding kinases (VEGFR, RAS,RAF, MLKL, mTOR, and PI3K), or an increase in their expression was observed—RIPK1, MAPK1, MAPK3, FLT3, and KIT (Figure 10A—black columns).
