Outline of Final Research Achievements

Gene expression dynamics in animal embryos are controlled by gene regulatory networks. To understand how gene regulatory networks produce such dynamics, analyzing regulatory mechanisms at the whole embryo level, but not at the individual gene level, is essential. In the present study, we used ascidian embryos, in which the gene regulatory network has been studied extensively, and succeeded in representing regulatory mechanisms for genes that begin to be expressed at the 32-cell stage as mathematical functions. Consequently, we can now calculate and manipulate gene expression dynamics of these genes with these mathematical functions.

Academic Significance and Societal Importance of the Research Achievements

動物の発生では時空間的に遺伝子発現が厳密に調節されることが必要である。この調節を担っているのが遺伝子調節ネットワークであるが、このネットワークがどのように時空間的な遺伝子発現ダイナミクスを生み出しているのかを、個々の遺伝子調節機構の理解の積み重ねだけで理解することは難しい。本研究により、動物胚の胚葉形成という重要なステップでの遺伝子調節ネットワークの働きが、計算可能になった。どのように遺伝子発現のダイナミクスが生じるのかを計算機上で再現可能になり、例えば実験操作によってどのような遺伝子発現の変化が生じるかなどの計算も可能となるなど、遺伝子調節ネットワークの機能の理解を大きく進める成果となった。
