Outline of Research at the Start

ゲノムに含まれる遺伝子の大半は未だ機能未知であり、その遺伝子機能を情報科学的に推定することは重要な研究課題である。本研究では、申請者が近年開発した、統計的論理関係解析法という枠組みにおいて高精度で遺伝子機能を推定する事を目的とする。具体的には、統計的論理関係解析法を様々な生物学的なデータセットに適用するための技術的な拡張や、開発した技術の実データセットへの適用による生物学的な知識発見を行う。

Outline of Final Research Achievements

This study aimed to develop novel software programs to estimate the function of function-unknown genes in genomes using statistical logical relationship analysis. In this study, we developed many programs for gene function estimation, e.g., (1) Logicome Profiler, an omics data analysis program that implements the statistical logical relationship analysis method, (2) MotiMul, a method for enumerating statistically significant sequence motifs (3) Mirage, which reconstructs a gene-content evolutionary history based on various gene gain/loss models by unsupervised classification of evolutionary patterns among gene families, (4) IPM, an accurate phylogenetic profiling method based on the inverse Potts model.

Academic Significance and Societal Importance of the Research Achievements

ゲノム決定技術の進歩により多様な生物のゲノムが決定されてきている一方で、ゲノムに含まれる遺伝子の多くは機能未知である。これら機能未知遺伝子の中には創薬・医療・カーボンニュートラルなどに関係する重要な遺伝子も多く含まれていると考えられるため、その遺伝子機能を推定するソフトウェア開発は生物学全般において重要な課題であるといえる。本研究は、統計的論理関係解析法と呼ばれるデータマイニング手法をベースに、さまざまな遺伝子機能推定ソフトウェアを開発した。本研究で開発したソフトウェアを広く活用することで、多くの機能未知遺伝子の機能が解明されることが期待される。
