Relative mRNA expression levels of NF-κB in irradiated HeLa, MCF7, CNE-2 and HCT116 cells treated with harvested CM/CM + OLA having previously conditioned the bystander cells (partnered with IRCs) for 1 h, followed by the replacement of media with FM and incubation until 12 h post-irradiation. Data were analysed using Student’s t-test: two-sample assuming unequal variances. ^*P < 0.05, ^**P < 0.01 and error bars represent mean ± SD.
