A research team consists of Kyoto Prefectural University of Medicine, Kansai Medical University Hospital, and National Institute of Advanced Industrial Science and Technology has developed a new drug screening method focusing on protein structure and clarified resistance the resistance mechanism of MEK inhibitors. They identified RPS5 (ribosomal protein S5) as a target protein of two natural plant components with cancer-inhibitory activity, and revealed that RPS5 is involved in the cell death resistance of the MEK inhibitor trametinib, one of the molecular target drugs. In addition, a new drug screening method has been developed that uses ABCI, a supercomputer, to search for drug candidate molecules by focusing on the structure of the protein.
The results were published in the scientific journal PNAS nexus on May 16, 2022 (local time).
