Outline of Final Research Achievements

In this study, I developed a new method for network modeling based on structural method. Furthermore, I improved the network modeling method for addition of structural restriction. For example, if there are known causality between the genes, I can estimate the network structure including the known causalities. I developed the numerical method to keep the elements which were known causalities within the co-variance matrices. I also improved my network optimization algorithm combined with GA algorithm to avoid the local minimum. I applied my developed and improved methods to real expression data, and I could select the activated sub-graph structure at the specific conditions.

Academic Significance and Societal Importance of the Research Achievements

本研究の学術的意義としては、従来法では困難であった少数データからのネットワーク構造推定が可能になる点が挙げられる。
具体的には、1.特定の条件下で活性化しているサブグラフの構造が明らかになることで、実際に生体内で機能している制御プロセスの解明に有用な情報になる。2.細胞内における異なった細胞内分子間の関係性が明らかになり、メカニズム解明に有用な情報になる。3.サブグラフ推定によって、細胞内のフィードバック制御やサイクリック制御のモデル化が可能になる。4.活性化部分の推定には多変量を必要としないことから、今後増加すると予想される1細胞計測データに適用可能である。
