Equations describing the dose-response relationship between the absorbed dose (0–10 Gy) of 60Co γ-rays (dose rate, 1 Gy/min) and GDF-15 protein expression levels in AHH-1 cells.
| Time post-irradiation (h) | Dose-response equation | R2 |
|---|---|---|
| 8 | – | – |
| 12 | y=1.81x-0.34 | 0.959 |
| 24 | y=0.43x+0.53 | 0.962 |
| 48 | y=0.33x+0.85 | 0.926 |

y, relative GDF-15 protein expression level (fold change); x, absorbed dose (Gy). GDF, growth/differentiation factor.
