On June 28–29, 2025, the 77th Annual Meeting of the Vitamin Society of Japan was held at Kitasato University, Faculty of Pharmacy, Shirogane Campus (Ōmura Memorial Hall).
The conference theme was:
“Wisdom and Practice in Vitamin and Biofactor Science.”

This meeting served as a vibrant platform for sharing the latest insights in vitamin and biofactor research, covering a broad spectrum from basic science to clinical applications.

Dr. Takeda Represented Our Lab as an Invited Speaker!

Our laboratory was represented by Dr. Kazuki Takeda, who delivered a Young Investigator Special Lecture (No. 5) titled:
“Deciphering Drug Sensitivity, Species Differences, and Individual Variability in Vitamin K Cycle-Related Proteins through Structural Science.”

In this talk, Dr. Takeda presented:

• Structural analysis of proteins involved in the vitamin K cycle

• Molecular interaction studies of warfarin (a drug and rodenticide) with vitamin K epoxide reductase

• Latest structural science approaches to understanding species and individual differences in warfarin sensitivity

Particular attention was given to the use of AlphaFold2-based structure prediction, molecular docking, and molecular dynamics simulations, which sparked active discussion and numerous questions from the audience.

Believe it or not, this was Dr. Takeda’s first-ever visit to the Shirokane Campus since joining Kitasato University four and a half years ago!
