BACKGROUND There is a worldwide problem of acute liver failure and mortality associated with remaining on the waiting for a liver transplant. In this study, we highlight results published in recent years by leading transplant centers in evaluating imatinib-induced acute liver failure in chronic myeloid leukemia and follow-up in liver transplantation. CASE PRESENTATION A 36-year-old brown-skin...

ALOX5 is implicated in chronic myeloid leukemia development in mouse leukemic stem cells, but its importance in human chronic myeloid leukemia is unknown. Functional ALOX5 was assessed using an LTB4 ELISA and ALOX5, and LTB4R1 mRNA expression was determined via a TaqMan gene expression assay. LTB4R1 and 5-LOX protein levels were assessed by cell surface flow cytometry analysis. At diagnosis ALO...

methods s. cerevisiae was cultured and then disrupted by sonication. after centrifugation, the harvested supernatant was considered to be a cytoplasmic extract. the protein concentration was determined by the biuret method and the extract was diluted to concentrations of 500, 1000, and 2000 µg protein/ml. the frequencies of apoptosis and necrosis were assessed in extract-treated k562 cells by e...

calcium metabolic disorders, such as hypercalcemia is a potentially life-threatening disorder especially when coupled with an already compromised condition. the aim of this study was to determine the prevalence of metabolic calcium disorders in childhood cancers of patients admitted to the pediatric ward of vali-asr hospital from the year 2001-2008. the study was carried out by reviewing hospit...

Since its discovery 10 years ago, the FIP1L1-PDGFRA mutation has been associated with a wide spectrum of hematopoietic neoplasms which range from T-lymphoblastic leukemia/lymphoma, chronic eosinophilic leukemia, chronic myeloid leukemia, acute myeloid leukemia, myeloid sarcoma and systemic mastocytosis. Common between these neoplasms was eosinophila and sensitivity to imatinib and other tyrosin...

Existing in vitro culture technology does not permit the routine propagation of most human myeloid leukemias. Previous work has shown the usefulness of mice with severe combined immunodeficiency (SCID) for the growth of human lymphoblastic leukemia. We show here that human myeloid cell lines and bone marrow samples from patients with acute myeloid leukemia (AML) and blast crisis of chronic myel...

introduction: leukemia is a malignant disorder resulting from clonal proliferation of lymphoid or myeloid precursors with arrested maturation. it has been shown recently that telomers and telomerase activity are involved in the control of cell proliferation, regulation of cell senescence in the most somatic cells, and unlimited proliferation capacity of the malignant cells including leukemic ce...

BACKGROUND Outcomes in chronic myeloid leukemia have improved with tyrosine kinase inhibitor treatment. However, little is known about outcomes of chronic myeloid leukemia in adolescent and young adult patients. DESIGN AND METHODS We reviewed all 468 chronic myeloid leukemia patients treated at our institution with tyrosine kinase inhibitors as initial therapy: imatinib (n=281), nilotinib (n=...

PTEN deletion in the mouse and in the zebrafish highlights the essential role of this tumor suppressor in the development of myeloid malignancies, in particular acute myeloid leukemia and myeloproliferative disorders. In humans, extensive genetic sequences of myeloid malignancies did not reveal recurrent PTEN mutations and deletions. However, PTEN was shown to be functionally inactivated in sev...
