The transforming genes of oncogenic retroviruses are homologous to a group of evolutionary conserved cellular onc genes. The human cellular homologue (c-abl) of the transforming sequence of Abelson murine leukaemia virus (A-MuL V) was recently shown to be located on chromosome 9. The long arm of this chromosome is involved in a specific translocation with(More)
Myelodysplastic syndromes (MDS) represent a heterogeneous group of neoplastic hematopoietic disorders. Several recurrent chromosomal aberrations have been associated with MDS, but the genes affected have remained largely unknown. To identify relevant genetic lesions involved in the pathogenesis of MDS, we conducted SNP array-based genomic profiling and(More)
The translocation (6;9)(p23;q34) in acute nonlymphocytic leukemia results in the formation of a highly consistent dek-can fusion gene. Translocation breakpoints invariably occur in single introns of dek and can, which were named icb-6 and icb-9, respectively. In a case of acute undifferentiated leukemia, a breakpoint was detected in icb-9 of can, whereas no(More)
The gene for the hereditary disorder neurofibromatosis type 2 (NF2), which predisposes for benign CNS tumors such as vestibular schwannomas and meningiomas, has been assigned to chromosome 22 and recently has been isolated. Mutations in the NF2 gene were found in both sporadic meningiomas and vestibular schwannomas. However, so far only 6 of the 16 exons of(More)
For long, T-cell acute lymphoblastic leukemia (T-ALL) remained in the shadow of precursor B-ALL because it was more seldom, and showed a normal karyotype in more than 50% of cases. The last decennia, intense research has been carried out on different fronts. On one side, development of normal thymocyte and its regulation mechanisms have been studied in(More)
The transcription factor Forkhead box protein P1 (FOXP1) is highly expressed in a proportion of diffuse large B-cell lymphoma (DLBCL). In this report, we provide cytogenetic and fluorescence in situ hybridization (FISH) data showing that FOXP1 (3p13) is recurrently targeted by chromosome translocations. The genomic rearrangement of FOXP1 was identified by(More)
We report on the establishment and characterization of 2 primary (EOM-3, EOM-29) and 3 metastatic uveal melanoma cell lines (OMM-1, OMM-2, OMM-3) and further cytogenetic characterization of a previously described primary uveal melanoma cell line (OCM-1). Only a few long-term growing primary uveal melanoma cell lines have as yet been established, while of(More)
The rad21 gene of Schizosaccharomyces pombe is involved in the repair of ionizing radiation-induced DNA double-strand breaks. The isolation of mouse and human putative homologs of rad21 is reported here. Alignment of the predicted amino acid sequence of Rad21 with the mammalian proteins showed that the similarity was distributed across the length of the(More)
Interphase fluorescence in situ hybridization (iFISH) is increasingly used for the identification of BCR/ABL gene rearrangements in chronic myeloid leukemia (CML) and acute lymphoblastic leukemia (ALL). In the present study, we have explored the incidence of both typical and atypical iFISH patterns of BCR/ABL gene rearrangements in a series of 168(More)
The localization of cellular oncogenes near the break points of tumour-specific chromosomal aberrations suggests an involvement of these genes in the generation of neoplasms. Recently, we demonstrated the translocation of the human cellular homologue (c-ab1) of the transforming sequence of Abelson murine leukaemia virus (A-MuLV) from chromosome 9 to the(More)
