Outline of Final Research Achievements

Fructose is a dietary monosaccharide present naturally in fruits and vegetables. Fructose is often used as white crystalline table sugar in the form of refined sugars. The effect of maternal fructose on offspring was examined. Pregnant rats were fed with 20% fructose solution. Offspring delivered from fructose-fed dams showed impaired glucose tolerance after mature. Their weigh was lower than control offspring.
There are several evidences that brain function is sensitive to fructose consumption. Decreased Uncoupling protein 5 (UCP5) mRNA was observed in fructose offspring. The adverse effect of maternal fructose is mediated by the alternation of UCP5 mRNA expression. Offspring hippocampal function might be affected by maternal fructose. Now, we try to examine the adverse effect of fructose from the point of view of epigenetics.
