Figure 3. Depletion of PINCH1, ILK or ILKAP differentially radiosensitized human glioblastoma cell lines.

Clonogenic radiation survival of glioblastoma cells after A. PINCH1, B. ILK or C. ILKAP knockdown was measured by colony formation assays. Cells were irradiated 48 hours after siRNA transfection. Non-specific siRNA was used as control (Co siRNA). Data are mean ± SD (n = 3; t-test; *P < 0.05, **P < 0.01).
