The formation of N-(2-hydroxyethyl)valine (HEVal) in hemoglobin was investigated in male F344 rats (10/group) and B6C3F1 mice (20/group) exposed to 0, 3, 10, 33, 100, or 300 (rats only) ppm ethylene oxide (ETO) by inhalation for 6 h/day for 4 weeks (5 days/week) or exposed to 100 (mice) or 300 ppm (rats) ETO for 1 or 3 days, or 1, 2, or 4 weeks (5 days/week). The persistence of HEVal was studie...
BACKGROUND/AIMS It has been demonstrated that KRAS mutations represent about 90% of cancer-associated mutations, and that KRAS mutations play an essential role in neoplastic transformation. Cancer-associated RAS mutations occur frequently in acute myeloid leukemia (AML), suggesting a functional role for Ras in leukemogenesis. METHODS We successfully established a mouse model of human leukemia...
Purpose Most mass customization literature focuses on the move from mass production to mass customization. However, in some literature Engineer-To-Order (ETO) companies are also claimed to have become mass customizers, although it can be questioned if these companies conform to popular definitions of mass customizers. This raises the question: Under which conditions is it reasonable to label ET...
Ethylene oxide (EtO) is a genotoxic carcinogen with widespread uses as an industrial chemical intermediate and sterilant. We examined the effects of glutathione S-transferase T1 (GSTT1) and M1 (GSTM1) genotypes on the levels of N-(2-hydroxyethyl)valine (HEV) adducts in the erythrocytes and sister chromatid exchange (SCE) in lymphocytes from a group of 58 operators of sterilizers that used EtO a...
A brief history of development of the 1985 Hargreaves equation and its comparison to evapotranspiration ~ET! predicted by the Food and Agricultural Organization of the United Nations ~FAO! Penman-Monteith method are described to provide background and information helpful in selecting an appropriate reference ET equation under various data situations. Early efforts in irrigation water requiremen...
The multiplicity of transcription factors involved in hematologic malignancies suggests a complicated scenario in which many different molecular mechanisms lead to malignant transformation. We hypothesized that some of these proteins might physically and functionally interact and thus mechanistically link different diseases. The ETO protein of t(8;21) acute myeloid leukemia (AML) is an excellen...
BACKGROUND AND PURPOSE Salinomycin (Sal) has recently been shown to inhibit various cancer stem cells. Here, we investigated whether Sal could sensitize cancer cells to the effects of doxorubicin (DOX) or etoposide (ETO). EXPERIMENTAL APPROACH Using the Comet assay, immunocytochemistry and Western blot analysis, we assessed the ability of Sal to increase DNA breakage. We performed a cell prol...
The t(8;21) translocation, which encodes the AML1-ETO fusion protein (now known as RUNX1-CBF2T1), is one of the most frequent translocations in acute myeloid leukemia, although its role in leukemogenesis is unclear. Here, we report that exogenous expression of AML1-ETO in human CD34(+) cells severely disrupts normal erythropoiesis, resulting in virtual abrogation of erythroid colony formation. ...
Chelating phosphines incorporating ethoxysilane functions for immobilizations have been synthesized and fully characterized. (EtO)Si(CH2PPh2)3, (EtO)2Si(CH2PPh2)2, and Si(CH2PPh2)4 could be prepared in high yields from cheap starting materials. The ethoxysilanes, as well as a Pd complex thereof have been characterized by X-ray structures, and immobilized on silica. The success of the immobiliza...
Nonrandom and somatically acquired chromosomal translocations can be identified in nearly 50% of human acute myeloid leukemias. One common chromosomal translocation in this disease is the 8q22;21q22 translocation. It involves the AML1 (RUNX1) gene on chromosome 21 and the ETO (MTG8, RUNX1T1) gene on chromosome 8 generating the AML1-ETO fusion proteins. In this review, we survey recent advances ...
