SNAI2 and glioblastoma: As shown in Figure 5B, U87 glioblastoma cells overexpressing SNAI2/Slug shRNA displayed decreased migration when compared to control cells (39 +/- 9 cells/hpf versus 72 +/- 7 cells/hpf, P < 0.0002, t-test), indicating a role for endogenous SNAI2/Slug expression in glioblastoma cell migration.
