Outline of Final Research Achievements

Autophagy is a major degradation system in eukaryotic cells. This study aimed at elucidating the mechanisms and physiological significance of organelle degradation by autophagy. Consequently, we revealed the mechanisms by which the nucleus and endoplasmic reticulum are deformed and sequestered within autophagosomes. We also showed how cells regulate autophagic degradation of peroxisomes. These results were published in international journals as three research articles. Moreover, our results provided significant insights into the regulation and physiological function of autophagy of the nucleus. These results will also be published soon.

Academic Significance and Societal Importance of the Research Achievements

本研究では、モデル生物である出芽酵母を用いて、明快な結果を得ることができた。成果は哺乳類を含む他の生物種のオートファジーの研究に対して重要な指針となるだけでなく、オルガネラや生体膜、細胞内分解といった細胞生物学の分野に広く大きなインパクトを与えるものである。また、オートファジーによるオルガネラの分解は、神経変性疾患などの病気と関連することが明らかとなってきた。本研究の成果は、将来的にこれら関連疾患の予防法や治療法の開発のための基盤情報として活用される可能性もある。
