ABSTRACT
The influence of feeding a diet without potatoes and diets containing 30% of non-transgenic or transgenic potatoes with overexpression of P 14-3-3 protein on antioxidant enzymes in blood and oxidative degradation in brain was determined in growing rats. The increase of activity of superoxide dismutase in blood and the concentration of 8-oxo-2’deoxyguanosine in brain tissue was similar in animals fed on both potato diets, which indicates that it was not related to genetic modification of tuber composition. The statistically significant differences in the investigated parameters did not result from the changes in the composition of the genetically modified potatoes caused by transgenesis.
