Outline of Final Research Achievements

Subcutaneous injection of ghrelin resulted in no significant changes in plasma GLP1 levels in wild type mice. Addition of ghrelin or desacyl ghrelin on primary cultured epithelial cells of mouse small intestine showed no significant effects on GIP, preproglucagon, PYY, and CCK mRNA levels. There were no significant changes in plasma GIP and GLP-1 levels and intestinal GIP, preproglucagon, PYY, and CCK mRNA levels in SAP-ghrelin transgenic mice. In conclusion, we could not find any evidence that ghrelin or desacyl ghrelin has effects on the expression or secretion of gastrointestinal hormones.

Academic Significance and Societal Importance of the Research Achievements

今回の検討により、グレリンあるいはデスアシルグレリンのGIP、GLP-1、CCK、PYYといった消化管ホルモンに与える影響は、存在したとしても大きくないことが判明した。一方で、デスアシルグレリンの慢性過剰状態はやはり耐糖能を改善することが確認された。以上の結果は、グレリンあるいはデスアシルグレリンの臨床応用を考える際の、消化管ホルモンを介した耐糖能への影響を確認したという意味で、学術的また社会的にも意義のある結果であると考えられた。
