Outline of Research at the Start

本研究計画では、インドネシアWallacea地域周辺で進化した哺乳類について、日本とインドネシアの研究者が協力することにより、先端的な分子研究を行うことを目指している。そのために現地(インドネシア)にDNAやRNAを用いた研究の拠点を立ち上げ、国境を越えた生物資源の移動無しに最先端の研究を実施する環境を形成する。それによりインドネシアと我が国双方の若手研究者を育成すると共に、以下に挙げるいくつかの生物進化の謎を解き明かす。具体的には、味覚と毛色という身体の内外の二つの表現型を対象に、霊長類と有袋類の進化が遺伝子の機能進化なのか、遺伝子発現変化なのかを解明する。

Outline of Annual Research Achievements

2023年度はマカク類と有袋類それぞれに毛色関連遺伝子等の解析を進めた。
マカク類については寺井と研究協力者のYan Xiaochanが、2023年11月にインドネシアを訪問し、スラウェシ島北中部にてM. nigraとM. tonkeanaの毛根からDNAとRNAの採取を行い、ボゴール農科大学で核酸抽出とライブラリの構築を行った。さらにこれらの網羅的な解析を井倉らと共同で行った。それぞれの種で毛色パターンが異なる背側と腕のRNAseqの結果、スラウェシマカク類の毛色制御に関わるいくつかの遺伝子候補を挙げることができた。また、2023年6-8月にインドネシアのボゴール農科大学から共同研究者のKanthi Widayatiが来日し、苦味受容体TAS2R38について実験を実施した。その結果をこれまでの結果と比較しながらdisucussionを進めた。
また、有袋類についてはWidayatiと同時期にボゴール農科大学からUrsula Paulawati Maker とAksamina Maria Yohanitaが来日し、それぞれBandicootとCuscusの毛色関連遺伝子MC1Rと毛色の多様性についてDNA配列の比較による相関解析を行った。その結果、BandicootのMC1Rについては毛色と関連するSNPが明らかになった。また、cuscusについては種に特異的な変異がMC1Rの機能多様性に関わっていることをカルシウムイメージング実験により示した。

Current Status of Research Progress
Current Status of Research Progress

1: Research has progressed more than it was originally planned.

Reason

マカク類については前年度と合わせて4種のマカク類の毛根からRNAを抽出してRNAseq解析まで進めることができたため。また、有袋類についてもBandicootのMC1Rの種内多様性とMC1Rの関連を解明することができた。cuscusについても、MC1Rの機能解析を実施することができた。

Strategy for Future Research Activity

RNAseqの解析をさらに進めると共に、RT-qPCR等の手法により、その妥当性を検証する。最終年度になるため、これまでの結果を論文や学会等で発表する。
