Expression profiling of normal murine lymphoid progenitors and MLL-AF4 leukemic lymphoblasts

We created a mouse model where conditional expression of physiologic levels of an Mll-AF4 fusion oncogene induces development of acute lymphoblastic (ALL) or acute myeloid leukemias (AML). Immunophenotypic and gene expression analysis of the ALL cells demonstrated bone marrow replacement with B-precursor cells which express a gene expression profile that has significant overlap with profiles in human MLL-rearranged ALL.
