KeywordsCyclocreatine / mouse
Outline of Final Research Achievements

Cyclocreatine was orally administered to creatine transporter (CRT) gene knockout mice for 3 weeks and the effects on cognitive and motor functions were evaluated. The results showed that although the targeted dose of cyclocreatine was almost achieved, there was no clear effect of the administration on visual cognitive function. One possible reason for this is that the duration of administration may not have been sufficient. The 3-week treatment period set in this study was too short, which may have resulted in a variation in responsiveness among the mice. In the future, it is necessary to extend the administration period and increase the samples size in each group to further examine the effects of cyclocreatine administration.

Academic Significance and Societal Importance of the Research Achievements

人口の高齢化に伴い患者が増加し続けているパーキンソン病、ハンチントン病等の致死性神経変性疾患は、アポトーシスによる神経脱落により発症することがわかっているものの、効果的な治療法は未だ確立されていない。そこで、今回、脳細胞内に移行しやすく、かつ生体で高い反応性を有するサイクロクレアチンを標的物質とし、その有効性を検証する動物実験を行った。しかしながら、視覚認知機能に対する投与効果を認めることはできなかった。今後、対象動物モデルや投与方法などを改善し、ヒト患者の治療法確立につながるデータ採取を目指す。
