Organism-level Systems Biology and its Applications in Mammalian Brain

Research

We focus on the realization of organism-level systems biology and its application to the elucidation of three states (NREM sleep, REM sleep, awake) of the mammalian brain. The systems-level identification and analysis of molecular and cellular networks in mammals can be accelerated by next-generation genetics. We recently established a highly efficient procedure for producing knock-out (KO) mice by ‘Triple-CRISPR’ method that targets a single gene by triple gRNAs in the CRISPR/Cas9 system achieves almost perfect KO efficiency (96%-100%). We also established a highly efficient procedure for producing knock-in (KI) mice within a single generation, by an ‘ES-mouse’ method. These procedures dramatically shorten the time required to produce KO or KI mice from a few year to ∼3 months. We also work on single-cell resolution whole-organ cell profiling realized by a tissue-clearing method ‘CUBIC’ and light-sheet microscopy. We recently found that Ca2+ and CaMKII-dependent hyperpolarization pathways underlie homeostasis of NREM sleep and that muscarinic receptors, M1 and M3, as essential genes for REM sleep. Further applications of these technologies will contribute to elucidating the mammalian brain and neurointelligence.

Biography

I was born in Fukuoka, Japan in 1975, graduated from the Faculty of Medicine, the University of Tokyo in 2000, and obtained Ph.D. in 2004 from the Graduate School of Medicine, the University of Tokyo. I was appointed as a team leader in RIKEN CDB from 2003 and promoted to Project Leader in 2009, and Group Director at RIKEN Quantitative Biology Center (QBiC) in 2011. I became a Professor of the Graduate School of Medicine, the University of Tokyo in 2013. I received awards, including the Tokyo Techno Forum 21, Gold Medal (Tokyo Techno Forum 21, 2005), Young Investigator Awards (MEXT, 2006) and IBM Science Award (IBM, 2009), a Young Investigator Promotion Awards (Japanese Society for Chronobiology, 2007), Tsukahara Award (Brain Science Foundation, 2012), Japan Innovator Awards (Nikkei Business Publications Inc. 2004), Yamazaki-Teiichi Prize (Foundation for Promotion of Material Science and Technology of Japan, 2015), Innovator of the Year (2017) and The Ichimura Prize in Science for Excellent Achievement (Ichimura Foundation for New Technology, 2018).
