Outline of Final Research Achievements |
Progesterone, which is produced in large quantities in the mitochondria of human placental cells, is an extremely important steroid hormone for the maintenance of pregnancy. Although the massive production of progesterone requires large-scale and efficient transport of cholesterol to the mitochondria, the molecular mechanism of this transport is still a puzzle. The principal investigators used 2D and 3D immunoelectron microscopy analyses to reveal the detailed structure between endosomes and mitochondria. This study has revealed part of the molecular mechanism of how progesterone is produced. This research also has the potential to shed light on how progesterone is secreted out of the cell.

Academic Significance and Societal Importance of the Research Achievements |
今回の研究によって輸送経路の微細構造やそこに局在する分子が判明すれば,本研究分野における大きな理解に繋がる。特に,謎の多い他の異種オルガネラ間が生む微細領域の詳細解明のための研究ツールとなり,波及効果が期待される。異種オルガネラ接近面の未知の微細構造を提示することで,我々に新鮮な疑問を投げかけ,接近面の新規の物質輸送機能の発見・解明へと推進する。本研究による胎盤細胞を用いたコレステロール輸送機構の解明は,妊娠の維持による胎児の安定的成長と体重確保や,出産後の健康保育などの課題の改善に繋がることが期待され,科学技術のみならず幅広い意味で社会に貢献できる。
