Figure 8: Synergistic effect of curcumin and radiation on clonogenic cell death in LNCaP cells. Cells were treated with curcumin (2.5, 5, and 10 �M) alone, radiation (2 Gy) alone or in combination of curcumin with radiation. A: Bar chart showing percent survival in different experimental groups (*p<0.05). B: A representative clonogenic assay showing different experimental groups.
