Venue: Hiroshima
Please note that registration for this year’s event is now closed.

The GTP Hackathon is a recurring program designed to bring together researchers working in the field of GTP biology, fostering interdisciplinary discussion and new collaborative research. Over the years, the event has served as a catalyst for innovative research ideas and joint projects, while also contributing to the development of research infrastructure and support for early-career scientists.

This year’s program will again feature the exchange of the latest research findings and discussions toward new directions in GTP biology. A summary report of the event will be shared on this website at a later date.

We appreciate your continued interest and support.

Dr. Shinichiro Takahashi's Visit and Lecture at the University of Cincinnati.
On March 4, 2025, we had the honor of hosting Dr. Shinichiro Takahashi, Professor at the Graduate School of Agricultural and Life Sciences, The University of Tokyo, at the University of Cincinnati for a lecture. As part of a joint initiative between MSTiC and UC-Tomorrow, Dr. Takahashi delivered an engaging talk, and many attendees listened attentively to his insights on his remarkable research activities.
Lecture Title: What kind of diet should humans eat in the future?

PI Atsuo T. Sasaki was invited to give a lecture at National Tsing Hua University, Taiwan on December 6, 2024.
Title: Decoding the evolving role of GTP energetics in bioregulation

Review Paper Accepted!
We are thrilled to announce that our review paper was accepted on New Year's Eve 2024, marking a joyful conclusion to the year for our team.
This paper provides a comprehensive overview of the current progress in therapeutic development targeting PI5P4K, with a particular focus on the development of inhibitors. We also delve into critical aspects of inhibitor development that have often been overlooked, presenting insights from cell biology, pharmacology, and structural biology in a manner accessible to researchers from various fields. Beyond PI5P4K, we believe this review will benefit those working on kinase-targeted therapies or with a general interest in therapeutic development. We hope you find it informative.

PI5P4K inhibitors: Promising opportunities and challenges.(Review)

From November 16th to 18th, members of our lab participated in the 3rd GTP Hackathon, held in Atami City, Shizuoka Prefecture. The keywords of this research retreat were "Food, Lifestyle, and Physiological Conditions." Topics included GTP as umami, vitamins, diet, health, and disease. Participants explored the connections between GTP and cellular environments down to the microscopic level, generating and sharing innovative ideas that emerged from these discussions. Our lab members presented their research through poster sessions, receiving valuable feedback. This event also provided an excellent opportunity to deepen connections with peers working on diverse research projects.

On November 14th, PI Sasaki gave a lecture at the Tropical Biosphere Research Center of the University of the Ryukyus.

FY2020 8th TBRC Seminar
“GTP metabolism and the dynamism of life: A new perspective on living organisms and disease control”
Point + What is important to you in order to have a prosperous career.”

On November 13th, PI Atsuo T. Sasaki will speak at Okinawa Institute of Science and Technology Graduate University (OIST).

Title: "Decoding the evolving role of GTP energetics in bioregulation"

Our lab students have researched the research career of our PI, Atsuo T. Sasaki, and compiled it into a video series (in Japanese).

1.PhD Stage
2.Postdoc Stage
3.PI Stage
It’s a three-part series. Please take a look!

A GTP GEEKS booth will also be on display at the 97th Japan Biochemical Society Convention to be held at Pacifico Yokohama on November 7th.
