Figure 2. YM-155 inhibits cell proliferation in malignant human glioma cell lines.
A, Glioma cells were incubated with varying concentrations of YM-155 for 72 hours; proliferation inhibition was assessed semiquantitatively by spectrophotometric measurement of MTS bioreduction. Points represent the mean of three measurements ± S.D. B, Glioma cells were seeded at 60% confluence, and allowed to attach overnight. Cell extracts were subjected to Western blotting analysis with the indicated antibodies. C, Glioma cells were treated with the indicated concentrations of YM-155 for 24 h. Cell extracts were subjected to Western blotting analysis with anti-survivin antibody. D, Glioma cells were grown as in B, and subjected to Western blotting analysis with the indicated antibodies. The blots were subsequently stripped and reprobed with total EGFR.
