Outline of Final Research Achievements

In this study, we have developed a reporter system that monitors intracellular iron concentration. By taking advantage of this system, we have conducted a CRISPR-based whole genome knockout screen to identify molecules that regulate the amount of intracellular iron dynamics. Those candidates include molecules involved in intracellular signal transduction, such as growth factor and cytokine signaling. Our study has revealed a reciprocal interaction between intracellular signaling pathway and iron metabolism.

Academic Significance and Societal Importance of the Research Achievements

鉄は生命活動に必須の微量金属で、生命はその起源から鉄を利用して代謝活動を行なってきたと考えられている。また、ヒトにおける鉄代謝異常症は貧血や発がん、神経変性疾患などの様々な病態に関与することが注目されているが、その疾患発症の分子メカニズムはあまり明らかになっていない。本研究により得られた成果は、鉄代謝ネットワークを形成するひとつひとつの構成分子を明らかにすることで鉄代謝制御機構に関する学術的理解を深めるだけでなく、今回同定された個々の分子を基盤に将来的な研究を発展させることによって、鉄代謝異常によるヒト疾患発症メカニズム解明への一助となることも期待される。
