FIG. 3.
Relative expression of three NK cell associated cytotoxic genes, GNLY (□), GZMA (△) and NKG7 (○), measured by qRT-PCR (panel a) and microarray hybridization (panel b) 48 h after radiation exposure. Each point represents the mean of relative induction above background in five independent donors. Error bars are standard errors of the mean. The dashed line shows the basal level of expression in unirradiated controls. The percentage of NK cells in the leukocyte population at 48 h relative to unirradiated controls (■) is also shown in panel a. This point represents the mean of three independent donors and error bars are standard error of the mean.
