X-ray-induced expression changes of TNFSF4 gene in human peripheral blood.

This study examined ionizing radiation-induced tumor necrosis factor (ligand) superfamily, member 4 (TNFSF4) mRNA expression changes in human peripheral blood cells and their distribution in a normal population. The results showed that expression level of TNFSF4 mRNA exhibited a dose-dependent response after different irradiation doses, but that was independent of incubation time post-irradiation. Moreover, it was not affected by age and gender in 51 healthy donors. Our studies indicate that TNFSF4 can be considered as a candidate gene to develop a new biodosimeter.
