Figure 4: Cell cycle distribution after curcumin and radiation treatment in LNCaP and PC3 cells. Cells were treated with curcumin (10 uM) alone or radiation (2 Gy) alone or in combination of curcumin (10 uM) with radiation (2 Gy). Cell cycle distribution was examined after 48 hr of radiation exposure and presented as percent G1, S, and G2/M. A: LNCaP B: PC3.
