The AML1/ETO fusion protein found in acute myeloid leukemias functions as a transcriptional regulator by recruiting co-repressor complexes to its DNA binding site. In order to extend the understanding of its role in preleukemia, we expressed AML1/ETO in a murine immortalized pluripotent hematopoietic stem/progenitor cell line, EML C1, and found that genes involved in functions such as cell-to-c...
Acute myeloid leukaemia (AML) is characterized by a block in myeloid differentiation the stage of which is dependent on the nature of the transforming oncogene and the developmental stage of the oncogenic hit. This is also true for the t(8;21) translocation that gives rise to the RUNX1-ETO fusion protein and initiates the most common form of human AML. Here we study the differentiation of mouse...
Deletions on chromosome 9q are seen in a subset of acute myeloid leukemia (AML) cases and are specifically associated with t(8;21) AML. We previously defined the commonly deleted region in del(9q) AML and characterized the genes in this interval. To determine the critical lost gene(s) that might cooperate with the AML1-ETO fusion gene produced by t(8;21), we developed a set of shRNAs directed a...
Normal blood-cell differentiation is controlled by regulated gene expression and signal transduction. Transcription deregulation due to chromosomal translocation is a common theme in hematopoietic neoplasms. AML1-ETO, which is a fusion protein generated by the 8;21 translocation that is commonly associated with the development of acute myeloid leukemia, fuses the AML1 runx family DNA-binding tr...
Alteration of lineage-specific transcriptional programs for hematopoiesis causes differentiation block and promotes leukemia development. Here, we show that AML1/ETO, the most common translocation fusion product in acute myeloid leukemia (AML), counteracts the activity of retinoic acid (RA), a transcriptional regulator of myelopoiesis. AML1/ETO participates in a protein complex with the RA rece...
BACKGROUND AND OBJECTIVES In spite of the high complete remission rate that chemotherapy achieves in acute myeloid leukemia with AML1-ETO gene rearrangement, relapse is a major cause of treatment failure in this condition. We aimed to determine a predictor of relapse with the real-time quantitative reverse transcription polymerase chain reaction (RQ-PCR) of AML1-ETO chimeric mRNA. DESIGN AND ...
abstract reference evapotranspiration (eto) is an essential parameter required for proper management of agricultural crop irrigation. eto is influenced by many different hydrological variables and as a result is a very complex procces. eto is usually estimated by empirical or process-orinented models (mathematical relationships) from historical weather data. the need for accurate estimates of e...
Extremely to slightly halophilic bacteria were tested for susceptibility to two sterilizing agents, peracetic acid (PAA) and ethylene oxide (ETO). PAA susceptibility was explored by two methods: an agar plate (constant pH of 7.2) and a filter strip (constant incubation period of 37 days); 100% susceptibility was obtained by both methods. The dosage (0.5 ml/min) was applied to a filter pad in a ...
It has been proposed that inhibitors of an oncogene's effects on multipotent hematopoietic progenitor cell differentiation may change the properties of the leukemic stem cells and complement the clinical use of cytotoxic drugs. Using zebrafish, we developed a robust in vivo hematopoietic differentiation assay that reflects the activity of the oncogene AML1-ETO. Screening for modifiers of AML1-E...
Ethylene oxide (EtO), propylene oxide (PO) and epichlorohydrin (ECH) are important industrial chemicals widely used as intermediates for various synthetic products. EtO and PO are also environmental pollutants. In this review we summarize data published during the period 1990-2001 concerning both the genotoxic and carcinogenic effects of these epoxides in humans. The use of DNA and hemoglobin a...
