Outline of Final Research Achievements |
In malaria parasites, transcriptional and translational mechanisms of mitochondrial DNA (mtDNA) remain unclear. To elucidate these mechanisms, we tried to generate a cell depleted of mtDNA using ethidium bromide (EtBr) in malaria parasites. Our study showed that the human malaria parasite has higher sensitivity to EtBr compared with a rodent malaria parasite. These findings would provide a valuable information to a study towards establishing a cell line depleted of mitochondrial DNA in malaria parasites.

Academic Significance and Societal Importance of the Research Achievements |
本研究の継続によりマラリア原虫のミトコンドリアDNA(mtDNA)の転写・翻訳機構が明らかとなれば、その機序はヒトのものとは大きく異なることが期待されるため、新規抗マラリア薬の有用な標的となり得る。また、マラリア原虫でmtDNAを消失させた細胞であるrho0細胞作出技術が確立されれば、同じ生物群に属する寄生生原虫であるトキソプラズマ、コクシジウム、ピロプラズマなどにも応用が効くことが予想され、生物学的に新たな知見が多く得られることが期待できる。
