Among the proteins, the concentration of which has been indicated to vary due to the gene expression or post-translational modifications induced by IR, we analysed the variation in concentration of AML, an indicator of radiation damage to the parotid gland 31, and FLT3L, used in estimating the severity of the haematopoietic syndrome in radiation accident victims 24. This evidence concerns the gene FLT3LG and acute myeloid leukemia.
