Figure 4From: HIF-1α inhibition by siRNA or chetomin in human malignant glioma cells: effects on hypoxic radioresistance and monitoring via CA9 expression Effects of HIF-1α-siRNA or CTM on Clonogenic Survival in U251MG and U343MG Cells (Cytotoxicity). A (U251MG) and B (U343MG), Effects of treatment with the indicated siRNA (75 nM) on the plating efficiency of non-irradiated cells. C (U251MG) and D (U343MG), Effects of treatment with 75 nM CTM on the plating efficiency of non-irradiated cells.Back to article page
