Fig.3 Main page of "KNApSAcK Family DB (http://kanaya.naist.jp/KNApSAcK_Family/).
This DB has become a world standard database consisting of metabolite-species relationships and cited by very large number of scientific papers.

Biomedical & health data sciencen

In collaboration with medical hospitals and other academic institutions, we are developing various biomedical engineering technologies based on information technology and state-of-the-art deep learning techniques.
By incorporating the strengths of the wearable/unconstrained sensing techniques and information technology such as deep learning techniques (CNN, GAN, etc.), we are developing health monitoring systems for medical and personal use.

  • A computer-aided diagnosis assistance system for medical images
  • A wearable deep body thermometer monitoring system
  • A cuffless blood pressure monitoring system
  • A heart health monitoring system based on contactless electrocardiograph

Systems biology & bio data science

Huge biological data sets, such as more than 1,000 genome sequences, have caused a paradigm shift into a holistic approach to understanding living things as systems. In this field, we keep incorporating state-of-the-art data modeling/manipulating techniques such as deep learning techniques to better our understanding.
With the development of omics technologies, it has become imperative to systematically analyze all biological components (genes, mRNA, proteins and metabolites). To meet this challenge, we have developed a clustering algorithm (DPClus, BiClus) to extract highly connected clusters.

Metabolomes & drug discovery

Cells consist of a few thousand molecules. Of those, metabolites are mainly produced by enzymatic reactions. The objective of metabolome analysis is to comprehensively identify which particular metabolites affect cellular networks. As a metabolome analysis platform, we have developed a species-metabolite database, KNApSAcK, covering almost all reported metabolites. To date, 50,048 metabolites and 101,500 species-metabolite relationships have been accumulated. We could extract metabolic pathway information using Molecular Graph Convolution Neural Networks MGCNN).

Key Features

Regardless of research backgrounds, we enjoy an interdisciplinary field between information technology and bio-medical science to mine and integrate knowledge in biology, medical science and health-care. "Let's do research on what we want!" is the motto of our lab.
