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.
