JAKing up AML1-ETO

摘要

In this issue of Blood, Chou et al 1 and Pulikkan et al 2 reveal that the (8;21)(q22;q22) translocation product AML1-ETO (RUNX1-RUNX1T1) leads to enhanced JAK/STAT signaling downstream of myeloproliferative leukemia (MPL) virus, which in turn contributes to increased survival of tumor cells. Hijacking of the JAK/STAT pathway through up-regulation of wild-type MPL is a new paradigm for hematologic malignancies.
