Labs spotlight #9 - Kotera Laboratory -
Massive omics data analysis using bioinformatics
The Department has a variety of laboratories for Life Science and Technology, in which cutting-edge innovative research is being undertaken not only in basic science and engineering but also in the areas of medicine, pharmacy, agriculture, and multidisciplinary sciences.
This "Spotlight" series features a laboratory from the Department and introduces you to the laboratory's research projects and outcomes. This time we focus on Kotera Laboratory.

Omics studies are becoming increasingly important in life sciences to collect and analyze comprehensive biomolecular data. Information technologies are requisite to deal with the vast amount of omics data and to discover the underlying biological rules. To date, however, the challenging issue remains in integrating two kinds of omics, i.e., gene-related omics (genomics, transcriptomics and proteomics) and chemical-related omics (metabolomics and glycomics).
We focus on the analyses of biochemical interactions as the following two perspectives: (1) Integration of genomic and chemical information on metabolic pathways. Recent development of metabolomics studies unveiled the increasing number of chemical compound for which the metabolic pathways are not known yet. We research on the automated method to predict and analyze such metabolic pathways and to link the genomic information. (2) Integration of genomic and chemical information on inter-species interaction. The relationship between insects and edible plants is mediated by a variety of chemical compounds produced by the plants and the receptor proteins in the insects. We research on the fundamental infrastructure to computationally analyze such interactions in the view of systems biology.
