background : fms-like tyrosine kinase 3 is a tyrosine kinase receptor that plays an important role in proliferation and differentiation of hematopoietic stem cells. internal tandem duplication and tyrosine kinase domain mutation are the two most common types of fms-like tyrosine kinase 3 mutations frequently reported in acute myeloid leukemia associated with pathogenesis of this disease. the pr...

The role of the recently identified first p53-homologue, p73, in neoplastic transformation is unknown. To elucidate p73 gene expression in hematopoiesis, we investigated samples from chronic myeloid leukemia (CML) and acute myeloid leukemia patients, leukemia cell lines, as well as mature and immature normal hematopoietic cells by real-time quantitative RT-PCR and Western blot analysis. We foun...

JEM © The Rockefeller University Press $15.00 Vol. 204, No. 3, March 19, 2007 461–465 www.jem.org/cgi/doi/10.1084/jem.20062335 461 Chronic myeloid leukemia (CML), which is caused by the BCR–ABL fusion tyrosine kinase, is one of the most intensively studied human cancers. ABL kinase inhibitors have been spectacularly successful in treating CML, but disease persistence and acquired drug resistanc...

In vitro studies show that BCR/ABL-expressing hematopoietic cells exhibit altered adhesion properties. No in vivo studies show whether the altered adhesion properties affect BCR/ABL leukemogenesis. Using mice with homozygous inactivation of genes encoding the 2 adhesion molecules P-selectin and intercellular adhesion molecule-1 (ICAM1), we show that the mutant mice develop BCR/ABL-induced chron...

Alterations of TWIST-1 expression are often seen in solid tumors and contribute to tumorigenesis and cancer progression. However, studies concerning its pathogenic role in leukemia are scarce. Our study shows that TWIST-1 is overexpressed in bone marrow mononuclear cells of patients with acute myeloid leukemia (AML) and chronic myeloid leukemia (CML). Gain-of-function and loss-of-function analy...

The oncomir microRNA-125b (miR-125b) is upregulated in a variety of human neoplastic blood disorders and constitutive upregulation of miR-125b in mice can promote myeloid and B-cell leukemia. We found that miR-125b promotes myeloid and B-cell neoplasm by inducing tumorigenesis in hematopoietic progenitor cells. Our study demonstrates that miR-125b induces myeloid leukemia by enhancing myeloid p...

Chronic myeloid leukemia (CML) is considered a common blood cancers and accounts for approximately 15–20% of the total cases leukemia. Recent studies indicated that above 95% patients suffering CML have been found with distinctive Philadelphia chromosome originates from mutual translocation between both arms chromosomes 9 22. During this mutation ABL gene located on get transferred to breakpoin...

Acute myeloid leukemia (AML) is a disease characterized by neoplastic transformation and abnormality of progenitor cells differentiation from cells. In AML there heterogeneous in hematopoietic cells, this has been identified affects the balance between proliferation, survival body Mutation FMS-like tyrosin kinase 3 (FLT3) gene causes overexpression which one most often found mechanism that coul...

Conditioned medium from phytohemagglutinin-stimulated human leukocytes contains a factor that can induce promyelocytic cell lines and certain acute myelogenous leukemia cells to differentiate along the monocytic pathway. In this report, we show that immature myeloid cells from normal bone marrow or the peripheral blood of patients with chronic myelogenous leukemia can be induced to differentiat...

Viral infections especially herpes virus and varicella zoster are common complications in patients with hematologic malignancies. The spectrum of infectious during after dasatinib therapy not known. I report here recurrent labialis two chronic myeloid leukemia cases treated dasatinib.
