MOTTO

There is nothing good or bad, only thinking makes it so

MOST IMPACTFUL PAPER

"Kaplan et al., VEGFR1-positive haematopoietic bone marrow progenitors initiate the pre-metastatic niche, Nature 2005."

I encountered this seminal work from Lyden's lab in 2010, which led me to choose my postdoctoral position where I spent the next nine years. The study highlights the potential for therapies that can inhibit cancer metastasis, positioning it as a cutting-edge piece of cancer research. Furthermore, this paper laid the foundation for my own work, leading to my first-author publication in Nature in 2015.

DREAM TO ACHIEVE THROUGH RESEARCH

I am working to achieve at least one research project that can lead to societal implementation, constantly asking myself, "What is the purpose of this science?" With this mindset, I aim to open new possibilities for diagnosing and treating diseases that are difficult to address with modern medicine. Additionally, I seek to expand activities that provide high school students with real research experiences, offering them opportunities to interact with researchers and fostering the next generation as a bridge to future scientific advancements.

RESEARCH THEME

Elucidation of DNA Replication and Genome Maintenance Mechanisms Using Proprietary Deglon Technology

PROFILE

Prof. Kanemaki graduated from the PhD Program at Chiba University in 2001 and studied in the UK as a postdoctoral researcher at the Cancer Research UK Manchester Institute from 2001 to 2006. He served as an assistant professor at Graduate School of Science, Osaka University from 2006 to 2010 and as an associate professor at Center for Frontier Research at National Institute of Genetics from 2010 to 2016. He was promoted to a professor in Department of Chromosome Science at National Institute of Genetics in 2016, and later became a professor in Graduate School of Science at The University of Tokyo in 2022.He developed the auxin-inducible degron (AID) technology, which utilizes the protein degradation mechanism in plants to enable rapid degradation of specific proteins. Furthermore, with the development of the improved AID2, he established a platform that allows for rapid protein degradation from yeast to mice. Alongside the development of genetic technologies, he is working on elucidating the mechanism by which genomic DNA is duplicated and maintained in human cells and in mice using the degron technologies.

MOTTO

"Earn dirty, spend clean."

It reflects the philosophy of some Osaka merchants, meaning to work hard and shrewdly in business, but use the profits ethically and wisely.

MOST IMPACTFUL PAPER

"Weinert, T.A., and Hartwell, L.H. (1988). The RAD9 gene controls the cell cycle response to DNA damage in Saccharomyces cerevisiae. Science 241, 317–322."

This paper by 2001 Nobel Prize laureate Lee Hartwell introduced the concept of cell cycle checkpoints. It’s amazing how he inferred what happens during the cell cycle simply by observing yeast mutants under a microscope! I was also deeply moved by his earlier work in the 1970s on identifying CDC cell cycle mutants for similar reasons. I believe my research foundation lies in yeast genetics.

DREAM TO ACHIEVE THROUGH RESEARCH

Everything has trends, but I prefer to take a step back and combine cutting-edge technology with the wisdom of the past to make new discoveries that many may have overlooked. I would be delighted if those I mentor continue to carry forward these ideas and aspirations.

Hideaki Kato, PhD

Professor, Research Center for Advanced Science and Technology, The University of Tokyo

RESEARCH THEME

Hideaki is exploring how living organisms sense and respond to physicochemical stimuli at the atomic level, using these insights to drive innovations in biotechnology. By studying the structure and function of proteins activated by light or magnetic fields, he is developing groundbreaking techniques to control biological processes. His work not only pushes the boundaries of basic science but also aims to create transformative applications in industry and healthcare.

PROFILE

From 2014 to 2019, Hideaki was a postdoctoral fellow at Stanford University School of Medicine. In 2019, he became an Associate Professor at the University of Tokyo, where he started his own lab, and since February 2024, he has held his current position.His research has primarily focused on microbial rhodopsins, exploring how these proteins convert light energy into molecular functions like ion transport. Rhodopsins, known for their ability to be activated by light and perform a variety of functions, are also key tools in optogenetics, where they are used to control neuronal activity with light. Driven by a passion for advancing this technology, he is working to apply optogenetics in both basic science and clinical research. Recently, he has expanded his studies to include proteins that respond to other physicochemical stimuli, such as magnetic fields, opening new avenues for innovation.

MOST IMPACTFUL PAPER

"The virophage as a unique parasite of the giant mimivirus. Bernard La Scola et al., Nature 2008"

This is a paper that deeply moved me when I was searching for a research theme after graduation. It describes the discovery of Mamavirus, the largest virus in the world, and the even more fascinating finding of a virus (Virophage Sputnik) that parasitizes and harms it. What impressed me the most was that these discoveries were made in a rather ordinary place—a cooling tower in France.

"Alexandra Zobel, Gabriele Neumann, Gerd Hobom, RNA polymerase I catalysed transcription of insert viral cDNA, Nucleic Acids Research, Volume 21, Issue 16, 11 August 1993, Pages 3607–3614"

While the artificial synthesis of several RNA viruses had become possible, it was thought that creating the influenza virus artificially was impossible due to its segmented genome, which is divided into eight segments, and the absence of cap and poly(A) structures at both ends. This paper was the starting point for establishing a synthetic system for the influenza virus.

I believe that any research is valuable if it is something that no one has really done before. That is why I want young researchers to be keenly aware of whether they are copying someone else or repeating themselves.Real innovation can only be found in unknown areas, and I hope and support that the activities of SS-F will encourage young people with a solid vision to freely conduct research, test new ideas, and make innovative discoveries one after another.

The world is shifting to a creator economy. In the coming era, it is extremely important to focus on the "individual" power of people called "creators" to create a series of one-of-a-kind inventions (discoveries and inventions) through the collision of "individuals" with "individuals.If we can support the realization of the free and flighty ideas of scientists, which is the highest form of creators, and build new communities as well as expand the points of contact with society, disruptive innovation to solve social issues on a global scale will easily occur. In this sense, I am deeply sympathetic to the SS-F concept and have great expectations for SS-F to create a new scientific economic sphere (ecosystem) for invention that transcends existing organizations. I believe that it is my responsibility as a member of the previous generation to support this new momentum to the best of my ability.

Throughout the entire history of science, the majority of innovative research has come from young researchers of the era. Of course, there are excellent researchers in Japan as well, but with the intensifying global competition in research, there is a possibility that our country's science will soon be left behind. This is why we need a mechanism to convert the wisdom of individuals into capital for scientific research, and SS-F's ability to select the best researchers, and its solution-oriented system, which is based on a thorough understanding of the issues, is genuine. I hope that this experiment will become a new hope for science in Japan as one of the ecosystems that will keep the fire of innovation burning.
