[Radiation-induced changes in protein synthesis in the liver of chicks at different stages of postnatal development]

Dynamics of changes in synthesis of cytoplasmatic and mitochondrial proteins in liver of chickens of various age exposed to low dose (0.05 Gy) ionizing radiation has been studied. It has been shown that low dose intensified the incorporation of labeled amino acids into the proteins in all the stages studied, although the degree and character of protein synthesis activation in cytoplasma and mitochondria are different. It is suggested that preincubation irradiation activates translational processes in cell, being one of the most important mechanisms of general stimulating effect of low doses.
