In order to explore RPS27L’s possibility as a biomarker of radiation damage, we studied its time-response and dose-response after irradiation as well as its background level. Three healthy adults’ peripheral blood was exposed to gamma-rays with 0, 0.5, 1, 2, 4, 6, and 10 Gy, separately and cultured for 2, 4, 8, 12, and 24 h respectively. RPS27L’s expression change was detected by quantitative real-time PCR. We also analyzed its background level in 37 individuals. The results showed that RPS27L had a significant difference at 4, 8, 12, 24 h and a great dose-independent response. There was also a uniform background level of RPS27L among different age and gender. Thus, RPS27L is of great potential to be a new biomarker of radiation.
