Keywords唾液腺
Outline of Research at the Start

唾液腺の発生機構に注目して唾液腺形成や再生に重要な遺伝子を発見し、遺伝子発現を誘導できるような薬剤の開発を目指す予定である。研究方法として、唾液腺の形成に関する重要な遺伝子を発見し、その遺伝子発現を誘導できるような薬剤を探索した後、唾液腺障害モデルを用いて再生医療へ応用する。将来的には、唾液腺で得られた知見を活用し、肺・腎臓・乳腺・涙腺などの他臓器の再生医療に発展させることを目標としている。

Outline of Final Research Achievements

We found that the p63 gene is expressed during salivary gland regeneration and is regulated by FGF7. The transcription factor p63, a component of the p53 family, has important functions in the development, homeostasis, and regeneration of epithelial tissues. However, the role of p63 in the regeneration of exocrine glands, including the salivary glands (SGs), has not been fully investigated. We investigated p63 expression in SG regeneration induced by duct ligation and irradiation. The expression of ΔNp63, a p63 isoform, increased and was colocalized with keratin 5 positive cells were myoepithelial cells. Furthermore, ΔNp63 expression was regulated by FGF7 stimulation via p38 MAPK phosphorylation and affected SG morphogenesis. These results suggest that ΔNp63 is essential for SG regeneration and may be a new target for regenerative treatment.

Academic Significance and Societal Importance of the Research Achievements

唾液腺再生時にp63遺伝子が発現すること、p63アイソフォームであるΔNp63がFGF7によって制御されることを見出した。さらに、p38 MAPK リン酸化を介した FGF7 刺激によってΔNp63が調節され、唾液腺の形態形成に影響を与えることを明らかにした。すなわち、p38 MAPKのリン酸やFGF7 刺激が誘導するΔNp63を制御できる薬剤を見出せば、唾液腺の再生を誘導できるかもしれない。薬剤を用いた臓器再生を誘導できる候補薬剤を見出す突破口になればと考えて、研究を継続している。
