Equations describing the dose-response relationship between the absorbed dose (0–8 Gy) of 60Co γ-rays (dose rate, 1 Gy/min) and GDF-15 mRNA expression levels in human peripheral blood lymphocytes.
| Time post-irradiation (h) | Dose-response equation | R2 |
|---|---|---|
| 4 | y=7,510x+23,380 | 0.797 |
| 8 | y=27,480x+47,200 | 0.970 |
| 12 | y=14,786x+75,212 | 0.851 |
| 24 | y=14,210x+79,197 | 0.955 |
| 48 | y=28,707x+72,207 | 0.899 |
y, number of GDF-15 mRNA copies/µl; x, absorbed dose (Gy); GDF, growth/differentiation factor.
