Radiation-induced genomic instability as measured by GFP-based assay in RKO36 cellsa
| X-ray dose (Gy) | No. of expts | Total no. of colonies scored | GFP+/− colonies (%) | SE (%) | Surviving fraction |
|---|---|---|---|---|---|
| 0 | 4 | 1,286 | 0.97 | 0.11 | 1 |
| 1.0 | 2 | 951 | 3.68 | 0.22 | 0.68 |
| 2.5 | 3 | 1,427 | 4.59* | 0.58 | 0.334 |
| 5.0 | 4 | 2,256 | 9.76* | 1.43 | 0.028 |
| 10.0 | 3 | 2,458 | 7.69* | 0.73 | 0.0009 |
Surviving fraction is the percentage of RKO36 cells surviving the given dose of radiation as determined by clonogenic survival. *, P < 0.05.
