FIGURE 3.
Influence of DMSO and aminoguanidine (AG) on the bystander effect in HepG2 cells and T98G cells under hypoxic conditions. Bystander tumor cells were treated with the conditioned medium harvested from irradiated conspecific cells. (A,C) Micronucleus induction in the bystander cells. (B,D) Survival fractions of bystander cells. a, p < 0.05 compared with the 0-Gy group; b, p < 0.05 compared with the 5-Gy group without chemical treatment.
