| Outline of Final Research Achievements |
We investigated the roles of MEK inhibitors in regulation of graft-versus-host disease (GVHD) and graft-versus-tumor (GVT) effects after allogeneic hematopoietic stem cell transplantation. We confirmed that a MEK inhibitor trametinib suppresses GVHD while sparing GVT effects in several different murine bone marrow transplant models. Meanwhile, the calcineurin inhibitor tacrolimus abrogated GVT effects, which confirmed the priority of trametinib. These results were published as a research article in JCI Insight in 2016 July, and were widely broadcasted. Currently, we are concentrating to design and start a clinical trial in humans with trametinib.
