Science of sleep – from molecules to organisms
A paradigm shift in biological research from reductionistic to synthetic approach has been undertaken in recent years. Even though the synthetic approach has been acknowledged as a central strategy of life science over the next few decades, basic technologies required in the synthetic approach, such like designing, controlling and manipulating biological molecules (DNAs, proteins and lipids) is remained to be established. The main tasks for laboratory for synthetic biology are to develop basic technologies for synthetic biology through close collaborative study within this center and to present pioneer studies in this new field.
In our laboratory, we are developing innovative techniques to answer biological questions through the interdisciplinary efforts of collaborating members from multiple backgrounds. We have achieved several breakthroughs. (Top: Synthesize) Toward understanding biological systems at the organism level, we facilitate genetics by using information technology and developing efficient methods to produce genetically modified mice. Next generation genetics does not require the crossing that conventional methods do and allows researchers to prepare multiple lines of genetically modified mice in parallel within just a couple of months (left). The triple-target CRISPR method can produce whole-body biallelic knockout (KO) mice at high-efficiently (>90%) in a single generation (middle). The ES mouse method is a highly efficient procedure for producing knock-in (KI) mice (right).
(left: Measure) The non-invasive respiration-based automated sleep phenotyping system – snappy sleep stager (SSS) – significantly simplifies and enhances the sleep phenotyping for which conventional methods required intricate and laborious work of a skilled researcher. (middle: See through) The tissue-clearing technique: CUBIC method innovates the way to observe deep inside of intact tissues by making them transparent. Example tissues shown above are brain, heart, liver, and kidney of mouse (from left to right). (right: Observe) The observation of transparent tissues is facilitated by a new technology of microscopy: light-sheet fluorescence microscopy (LSFM).
