Outline of Final Research Achievements

In this study, we have developed the method of fusing protoplast of budding yeast or micronuclei which purified from mouse A9 culutured cells with liposomes, a lipid-bilayer compartments.In addition, we developed the pore forming method on liposome membrane by using streptolysin O, which is a protein known for forming pores on the lipid membrane composed of cholesterol. Using this method, we showed that proteins can penetrate the liposome membrane via the pores and RNA synthesis occurred in the liposomes by supplied enzyme. The methods we developed in the study enable us to supply proteins to chromosmes struture in liposomes. Thus, it help to elucidate the molecular mechanism of regulating chromosome sturcutres.

Academic Significance and Societal Importance of the Research Achievements

本研究成果は、これまで細胞を用いた実験系でしか取り扱うことのできなかった染色体をリポソームという膜区画を用いることで、細胞外に取り出すことを可能にした。染色体の制御の破綻は白内障やガンなどの老化に伴って発症する様々な疾患に関わっていることが示唆されているが、細胞を用いた系では、細胞が死なないという条件に縛られた解析しかできない。本研究では、どのような分子がどのように染色体制御と関わっているかを非細胞環境下で解析が可能となり、既存の実験系と合わせることで染色体制御機構を詳細に解明できることが期待される。
