Analysis of survival rates by Luminescent cell viability assay showed a significant (P < 0.05) decrease in GBM cell proliferation (both U251 and U87) with MPS1 (siMPS1 (lane 4, Figure 4A, 4C) or NMSP715 (lane 3, Figure 4B, 4D)) or miR-21 (si miR-21) inhibition (lane 5, Figure 4A, 4C). Here, TTK is linked to glioblastoma.
