Abstract

The review considers investigations presenting experimental data on the embryotoxic and teratogenic effects of exposure to ionizing radiation in zebrafish (Danio rerio) which is a convenient model for experimental embryology and radiation biology. The molecular mechanisms involved in response to the ionizing radiation influence as well as determining the embryonic death level, development disorders of embryos are examined. The data on acute and chronic effects of ionizing radiation on embryos of various stages of development with wide range of dose rates are presented. It was shown that the influence of γ-radiation on the death and development of zebrafish embryos is nonmonotonic and depends both on the irradiation conditions and on the stage of embryogenesis. The results of such studies are extremely important for understanding the mechanisms of radiation-induced biological effects formation in the embryogenesis of vertebrates, including humans, as well as for developing methods and approaches to assessing radiation risk for a developing organism.
