Outline of Final Research Achievements

To clarify the neural basis of the pH sensitivity of the sea catfish, expression of the immediate early genes (c-fos, egr-1, npas4), marker of neural activity, was examined. These genes expressed in larger number of neurons of the brains that induced excessive neural activity than those of untreated ones. These results indicate that it is possible to detect neurons that respond to stimuli by using the expression of the immediate early genes in the nervous system of sea catfish as in other animals. We also could confirm the expression of marker genes of the excitatory and inhibitory neurons in the nervous system of sea catfish.

Academic Significance and Societal Importance of the Research Achievements

多くのナマズ目魚類と同様に、味覚の鋭敏なゴンズイは、これまで味覚系の研究の優れた実験材料として利用されてきた。神経系の機能解析において有力な手段であり、他の動物これまで利用されてきた、最初期遺伝子の発現を指標として刺激に応答する神経細胞を検出する方法が、ゴンズイでも利用可能であることが示された。また、トランスクリプトーム解析のデータより、いくつかの神経細胞のマーカー遺伝子の塩基配列を得ることができ、その情報を基にそれらの遺伝子を発現する神経細胞の標識が可能となった。これらの手法は、今後のゴンズイにおける味覚情報処理の仕組みの解明のために有力な手段となる。
