Background and Aim of Study: There are two different phases untreated chronic myeloid leukemia – phase, blast crisis according to the World Health Organization classification Hematolymphoid tumors. The cells in can express myeloid, lymphoid, bi-phenotypic, monocytic, megakaryocytic, erythroid phenotypes. immunophenotype population determines how patients respond treatment, hence flowcytometric ...

Concurrent development of acute myeloid leukemia (AML) and chronic lymphocytic (CLL) is very rare. We present a case simultaneous CLL AML in patient with no prior exposure to cytotoxic agents or irradiation.

Differentiation inhibitory factor (nm23 protein) inhibited the induction of differentiation of mouse myeloid leukemia M1 and WEHI-3BD+ and human erythroleukemia HEL, KU812, and K562 cells. Block of differentiation may be associated with the aggressive behavior of leukemia. To examine the role of nm23 in human myeloid leukemia, we investigated the relative levels of nm23-H1, nm23-H2, and c-myc t...

Simian antisera to human leukemia cells were able to distinguish antigens specific for lymphocytic types of leukemia from those expressed on certain myeloid leukemia cells. In this investigation, cells from acute myelomonocytic leukemia patients (AMML) were examined for their membrane-associated leukemia antigens. Simian antisera to both lymphocytic and myelogenous leukemia cells lysed cells fr...

Dok-1 and Dok-2 are closely related rasGAP-associated docking proteins expressed preferentially in hematopoietic cells. Although they are phosphorylated upon activation of many protein tyrosine kinases (PTKs), including those coupled with cytokine receptors and oncogenic PTKs like Bcr-Abl, their physiological roles are largely unidentified. Here, we generated mice lacking Dok-1 and/or Dok-2, wh...

Achievement of complete molecular response in patients with chronic phase chronic myeloid leukemia has been recognized as an important milestone in therapy cessation and treatment-free remission; the identification of predictors of complete molecular response in these patients is, therefore, important. This study evaluated complete molecular response rates in imatinib-treated chronic phase chro...

The response of human myeloid leukemia cells to various sources of colony-stimulating activity (CSA) and media conditioned by phytohemagglutinin-stimulated mononuclear cells (PHA-LCM) was investigated in liquid and colony culture. PHA-LCM, placenta-conditioned medium, GCT cell line-conditioned medium, leukocyte-conditioned medium, and partially purified CSA for human and murine cells were teste...
