We assessed lineage involvement by NUP98 translocations in myelodysplastic syndromes (MDS), acute myeloid leukaemia (AML), and T-cell acute lymphoblastic leukaemia (T-ALL). Single cell analysis by FICTION (Fluorescence Immunophenotype and Interphase Cytogenetics as a Tool for Investigation of Neoplasms) showed that, despite diverse partners, i.e. NSD1, DDX10, RAP1GDS1, and LNP1, NUP98 translocations always affected a CD34+/CD133+ hematopoietic precursor. Interestingly the abnormal clone included myelomonocytes, erythroid cells, B- and T- lymphocytes in MDS/AML and only CD7+/CD3+ cells in T-ALL...

We set up a diagnostic double-color double-fusion fluorescence in situ hybridization (DCDF-FISH) assay to investigate a case of a de novo acute myeloid leukemia (AML)-M4 bearing an inv(11)(p15q22). DCDF-FISH detected the NUP98-DDX10 rearrangement as two fusion signals, at the short and the long arms of the inv(11). Reverse transcription-polymerase chain reaction (RT-PCR) and cloning experiments confirmed the NUP98-DDX10 fusion and identified two splicing fusion isoforms: the known "type II fusion," originating from the fusion of NUP98 exon 14 to DDX10 exon 7 and a new in-frame fusion transcript between NUP98 exon 15 and DDX10 exon 7, which we termed "type III fusion...

NUP98 gene rearrangements occur in acute myeloid leukemia and result in the expression of fusion proteins. One of the most frequent is NUP98-DDX10 that fuses a portion of NUP98 to a portion of DDX10, a putative DEAD-box RNA helicase. Here, we show that NUP98-DDX10 dramatically increases proliferation and self-renewal of primary human CD34+ cells, and disrupts their erythroid and myeloid differentiation. It localizes to their nuclei and extensively deregulates gene expression. Comparison to another leukemogenic NUP98 fusion, NUP98-HOXA9, reveals a number of genes deregulated by both oncoproteins, including HOX genes, COX-2, MYCN, ANGPT1, REN, HEY1, SOX4 and others...

NUP98 is a nucleoporin that plays complex roles in the nucleocytoplasmic trafficking of macromolecules. Rearrangements of the NUP98 gene in human leukemia result in the expression of numerous fusion oncoproteins whose effect on nucleocytoplasmic trafficking is poorly understood. The present study was undertaken to determine the effects of leukemogenic NUP98 fusion proteins on CRM1-mediated nuclear export. NUP98-HOXA9, a prototypic NUP98 fusion, inhibited the nuclear export of two known CRM1 substrates: mutated cytoplasmic nucleophosmin and HIV-1 Rev...

The inv(11)(p15q22), a rare but recurrent chromosome abnormality that creates a NUP98-DDX10 fusion gene, is associated with de novo or secondary myeloid malignancies. We report a case of acute monocytic leukemia presenting this rearrangement, studied using fluorescence in situ hybridization (FISH) and reverse transcriptase-PCR (RT-PCR). We also review the cases of inv(11) associated with NUP98-DDX10 reported in the literature.

BACKGROUND AND OBJECTIVES: The aim of this study was to determine the incidence of rearrangements of NUP98 (the gene coding for nucleoporin 98kDa protein) in childhood acute myeloid leukemia (AML) and selected patients with 11p13-15 rearrangements. This aim was achieved using a fluorescence in situ hybridization (FISH) assay that allows the detection of NUP98 aberrations independently of the partner gene involved. DESIGN AND METHODS: Screening of 59 consecutive patients enrolled in the Austrian AML-BFM93 clinical trial was performed by dual-color FISH...

The BCR/ABL tyrosine kinase inhibitor imatinib has shown remarkable efficacy in treating patients with chronic myelogenous leukemia (CML). In a small portion of patients treated with imatinib, however, the disease may progress to advanced stages, frequently accompanied by cytogenetic clonal evolution with the appearance of additional chromosomal aberrations besides the Philadelphia chromosome. Here we report the appearance of an inv(11)(p15q22) as a clonal evolution in a CML patient undergoing treatment with imatinib...

We report a 50-year-old man who developed therapy-related myelodysplastic syndrome after treatment with etoposide-including chemotherapy for extratesticular germ cell tumor. Chromosomal analysis showed inversion 11 (p15q22) translocation. Reverse transcriptase-polymerase chain reaction amplification of patient RNA showed a fusion transcript of nucleoporin gene NUP98, and putative DEAD-box RNA helicase gene DDX10. NUP98 is implicated in the transformation through aberrant nucleocytoplasmic transport. DDX10 is suggested to be involved in ribosome assembly...

Chromosomal abnormalities involving the 11p15 or 11q22-23 bands have been reported in several types of human neoplasms including hematopoietic malignancies. The abnormalities are observed in therapy-related malignancies and less frequently in de novo myeloid malignancies. Abnormality of the MLL gene located on chromosome 11q23 has been well known in therapy-related myeloid malignancies, but it has been reported only recently that the inv(11)(p15q22) in de novo or therapy-related myeloid malignancies results in the fusion of NUP98 on chromosome 11p15 and DDX10 on chromosome 11q22...

A novel chromosomal translocation, t(2;11)(q31;p15), was identified in a patient with therapy-related acute myelogenous leukemia (t-AML). Fluorescence in situ hybridization experiments mapped the breakpoint near NUP98; Southern blot analysis demonstrated that the nucleoporin gene NUP98 was disrupted by this translocation. We used rapid amplification of cDNA ends to identify a chimeric mRNA. An in-frame, chimeric mRNA that fused NUP98 sequences to the homeobox gene HOXD13 was cloned; the predicted fusion protein contains both the GLFG repeats from NUP98 as well as the homeodomain from HOXD13...

The inv(11)(p15q22) is a recurrent chromosomal abnormality associated with de novo and therapy-related myeloid malignancies. Here we report the molecular definition of this chromosomal aberration in four patients. Positional cloning showed the consistent rearrangement of the DDX10 gene on chromosome 11q22, which encodes a putative RNA helicase. The translocation targets the NUP98 gene on 11p15, a member of the FG peptide repeat nucleoporin family. In DDX10 and NUP98, the inv(11) breakpoints occurred within two introns of each gene and the two genes merged in-frame to produce the chimeric transcripts characteristic of this translocation...
