| Outline of Final Research Achievements |
One of the major indicators of poor prognosis in leukemia patients is extramedullary infiltration or dissemination of leukemia cells. In particular, leukemia cell infiltration into the central nervous system is one of the major complications negatively influencing prognosis. However, little is known about the mechanisms responsible for extramedullary dissemination of leukemia cells compared to those responsible for solid tumor metastasis. In the present study, we have identified molecular mechanism responsible for the enhanced chemotaxis towards chemokine CXCL12 that is induced by the Internal Tandem Duplication mutation of FLT3 gene (FLT3/ITD) associated with extremely poor prognosis. We subsequently investigated if antagonizing this particular molecular mechanism can be utilized for the treatment to block the unnecessary migration of the hematopoietic cells with FLT3/ITD.
