Genetic deletion of CXCR4 in murine hematopoietic progenitors abrogated leukemogenesis induced by constitutively active Notch1, whereas lack of CCR6 and CCR7, which have been shown to be involved in T cell and leukemia extravasation into the central nervous system, respectively, did not influence T cell acute lymphoblastic leukemia development.

Although it is unlikely that the Rb gene is directly involved in this translocation, the loss of the Rb gene product combined with the activation of the EVI1 gene may have led to the development of leukemia.

We propose that rearrangements at 3q26 involving EVI1 could result in leukemia by a two-step process involving first transcriptional disruption of MDS1/EVI1, and next by inappropriately activating expression of EVI1.

Overexpression of EVI-1 also occurs with high frequency in leukemia patients without 3q26 abnormalities, and importantly, high EVI-1 expression is an independent negative prognostic indicator irrespective of the presence of 3q26 rearrangements.

These data indicate that expression of the EVI1 gene is involved in progression of megakaryocytic differentiation and, thus, the dysmegakaryocytopoiesis in 3q21q26 syndrome could be partly due to an enhanced differentiation capacity of leukemia cells and/or megakaryocytes by constitutive expression of the EVI1 gene.
