Outline of Research at the Start

近年、末梢体内時計の障害は生活習慣病の一因であることが明らかになってきた。しかし、末梢時計が障害される機序は未だ明確ではなく、その治療法も確立していない。そこで本研究は、モデルマウスの肝細胞や脂肪細胞をシングルセルレベルで解析することにより、肥満2型糖尿病と関連する末梢時計障害の本態を明らかにする。さらに、遺伝子改変マウスを用いて、消化管ホルモンGLP-1が体内時計を制御する機構を解明することにより、末梢時計障害の治療基盤を確立する。

Outline of Final Research Achievements

Accumulating evidence indicates that disruption of the circadian clock contributes to the development of lifestyle-related diseases. We have previously shown that exenatide, a glucagon-like peptide-1 (GLP-1) receptor agonist, can strongly affect the molecular clocks. This study aimed to investigate the underlying mechanism and appropriate regimen of exenatide in mice. Exenatide administration at the beginning of the active period (i.e., in the morning for humans), but not at the beginning of the rest period, counteracted the phase shift effect of the rest period-restricted feeding. On the other hand, exenatide did not influence the phase of the hepatic clock under the active period-restricted feeding regardless of the dosing time. The effect of exenatide in wild-type mice weakened in central nervous system-specific GLP-1 receptor knockout mice. These findings may be useful in developing novel therapeutic strategies to prevent the onset and progression of lifestyle-related diseases.

Academic Significance and Societal Importance of the Research Achievements

本研究により、GLP-1受容体作動薬の体内時計を適切な時刻に投与することにより不規則な生活による体内時計障害を抑制できることが明らかになった。また、規則正しい生活をしている場合にはGLP-1受容体作動薬をいつ投与しても問題ないこと、GLP-1受容体作動薬は中枢神経を介して末梢臓器の体内時計を制御することも判明した。これらの成果はGLP-1受容体作動薬の治療効果の向上や新たな生活習慣病治療薬の開発につながる可能性があり、それらが実現した際の社会的意義は大きい。
