Outline of Final Research Achievements

In the present study, we demonstrated that nobiletin, a citrus peel component, can induce the neuronal differentiation through modulation of expression and activities of particular genes and proteins, and suppress the expression of thioredoxin-interacting protein (TXNIP), which deteriorates oxidative and endoplasmic reticulum stress, being a pathological characteristics of Alzheimer's disease (AD). However, dementia-protective effect could not be proved in a trial of prolonged oral administration of nobiletin with AD model mice.

Academic Significance and Societal Importance of the Research Achievements

本研究で得られた研究成果は、ノビレチンおよびノビレチンを高含有する柑橘類果皮エキスの認知症改善・予防への活用につながる科学的エビデンスとなるのみならず、本研究で挙げたタンパク質や遺伝子は、認知症改善や予防の分子標的となり得ると思われる。したがって、これら分子標的を活用することにより、ノビレチン以外の食品成分や医薬品の認知症改善・予防への応用につながるものと考える。
