Background: Myelodysplastic syndromes (MDS) are subtypes of hematological disorders which are known to have partial bone marrow dysplasia, peripheral cytopenia, and later on an increased risk to develop acute myeloid leukemia. Chromosomal aberrations are detected in ~50% of cases of de novo MDS cases and the most common chromosomal abnormalities of this entity include complete or partial monoso...
To validate a 2-step FISH assay for the identification of the t(9;11)(p22;q23), 96 acute myeloid leukemias were studied by cytogenetic analysis, FISH and molecular biology. After a first FISH step using an MLL probe, 24/27 cases with 11q23 break showed MLL rearrangement. Southern blotting confirmed FISH data. In the second step, 24 cases with MLL rearrangement were studied using MLL and AF9 pro...
Erythropoietin-producing hepatoma-amplified sequence (Eph) receptor tyrosine kinases and their cell-surface-bound ligands, the ephrins, function as a unique signaling system triggered by cell-to-cell interaction and have been shown to mediate neurodevelopmental processes. In addition, recent studies showed deregulation of some of Eph/ephrin genes in human malignancies, suggesting the involvemen...
Surface marker and gene rearrangement data have supported various hypotheses about the origin of the malignant cell in Hodgkin's disease. Cytogenetic data about this disorder, however, are very scanty. To determine if any chromosomal abnormalities that could add further information to this controversial point are present, we studied tumor samples from 49 patients. Abnormal metaphases were obtai...
introduction: bacterial translocation is defined as the passage of bacteria from intestinal tract to the extraintestinal organs such as the peritoneum and blood circulation. the aim of this study is to examine bacterial translocation (regarding type of bacteria and effect of time of obstruction on bacterial translocation) from intestinal lumen to the peritoneum and viscera in acute, simple mech...
Chromosomal aberrations (CAs) have emerged as important pathogenetic and prognostic factors in plasma cell disorders. Using interphase fluorescence in situ hybridization (FISH) analysis, we evaluated CAs in a series of 75 patients with amyloid light chain amyloidosis (AL) as compared with 127 patients with monoclonal gammopathy of unknown significance (MGUS). We investigated IgH translocations ...
The present report describes a unique infantile acute lymphoblastic leukemia (ALL) case with cryptic mixed-lineage leukemia (MLL) rearrangements with 11q23 chromosomal translocation. MLL break-apart signals were identified by fluorescence in situ hybridization, and transcriptome sequencing revealed MLL-myeloid/lymphoid or mixed-lineage leukemia; translocated To, 10 (MLLT10)/AF10 fusion transcri...
Translocations involving the MLL gene at 11q23 are a frequent finding in therapy-related leukemia and are concentrated within a short, 8.3-kb tract of DNA, the breakpoint cluster region. In addition, a specific site adjacent to exon 12 within this region of MLL is cleaved in cells undergoing apoptosis. We show here, using human TK6 lymphoblastoid cells, that irradiation and the apoptotic trigge...
