Xenograft studies indicate that some solid tumors and leukemias are organized as cellular hierarchies sustained by cancer stem cells (CSCs). Despite the promise of the CSC model, its relevance in humans remains uncertain. Here we show that acute myeloid leukemia (AML) follows a CSC model on the basis of sorting multiple populations from each of 16 primary(More)
Patients with cytogenetically normal acute myeloid leukemia (CN-AML) show heterogeneous treatment outcomes. We used gene-expression profiling to develop a gene signature that predicts overall survival (OS) in CN-AML. Based on data from 163 patients treated in the German AMLCG 1999 trial and analyzed on oligonucleotide microarrays, we used supervised(More)
PURPOSE CBL is a negative regulator of activated receptor tyrosine kinases (RTK). In this study, we determined the frequency of CBL mutations in acute leukemias and evaluated the oncogenic potential of mutant CBL. EXPERIMENTAL DESIGN The cDNA of 300 acute myeloid leukemia (AML)/myelodysplastic syndrome (MDS) and acute lymphoblastic leukemia (ALL) patients(More)
Lymphoid enhancer-binding factor-1 (LEF1) is a key transcription factor of Wnt signaling. We recently showed that aberrant LEF1 expression induces acute myeloid leukemia (AML) in mice, and found high LEF1 expression in a subset of cytogenetically normal AML (CN-AML) patients. Whether LEF1 expression associates with clinical and molecular patient(More)
High-dose therapy (HDT) followed by autologous transplantation of hematopoietic stem cells (ASCT) is frequently performed in patients with lymphoma. For many subentities, reliable results from prospective randomized studies are missing. In Hodgkin's disease (HD), HDT/ASCT is a standard indication for patients with chemosensitive first relapse. Patients with(More)

PURPOSE Recently, several novel molecular prognostic markers were identified in cytogenetically normal acute myeloid leukemia (CN-AML). In addition to the well-known influence of FLT3, NPM1, and CEBPA mutations, high transcript levels of the ERG, BAALC, and MN1 genes have been associated with inferior outcomes, but the relative importance of these risk(More)
HOX genes, notably members of the HOXA cluster, and HOX cofactors have increasingly been linked to human leukemia. Intriguingly, HOXD13, a member of the HOXD cluster not normally expressed in hematopoietic cells, was recently identified as a partner of NUP98 in a t(2;11) translocation associated with t-AML/MDS. We have now tested directly the leukemogenic(More)
A challenge for the development of therapies selectively targeting leukemic stem cells in acute myeloid leukemia (AML) is their similarity to normal hematopoietic stem cells (HSCs). Here we demonstrate that the leukemia-propagating cell in murine CALM/AF10-positive AML differs from normal HSCs by B220 surface expression and immunoglobulin heavy chain(More)
Identification of the molecular mechanisms that can promote human hematopoietic stem cell amplification is a major goal in experimental and clinical hematology. Recent data indicate that a variety of regulatory molecules active in early development may also play a role in the maintenance of hematopoietic stem cells with repopulating activity. One important(More)
