Molecular detection of c-mpl thrombopoietin receptor gene expression in chronic myeloproliferative disorders.
BACKGROUND Chronic myeloproliferative disorders (CMPD) originate from a pluripotent haematopoietic progenitor cell but show a marked degree of heterogeneity, especially between Philadelphia chromosome positive and negative disease entities. Abnormal megakaryopoiesis is a frequent finding in CMPD, often associated with thrombocythaemic cell counts. Recent experimental data have suggested that th...
متن کاملUbiquitination and degradation of the thrombopoietin receptor c-Mpl.
Regulation of growth factor and cytokine signaling is essential for maintaining physiologic numbers of circulating hematopoietic cells. Thrombopoietin (Tpo), acting through its receptor c-Mpl, is required for hematopoietic stem cell maintenance and megakaryopoiesis. Therefore, the negative regulation of Tpo signaling is critical in many aspects of hematopoiesis. In this study, we determine the ...
متن کاملThrombopoietin supports in vitro erythroid differentiation via its specific receptor c-Mpl in a human leukemia cell line.
Thrombopoietin (TPO) acts on megakaryopoiesis and erythropoiesis in vitro and in vivo. We isolated a novel subline, UT-7/GMT, from the human leukemia cell line UT-7/GM (N. Komatsu, et al., Blood, 89: 4021-4033, 1997). A small population of UT-7/GM cells positively stained for hemoglobin (Hb) after a 7-day exposure to TPO. More than 50% of TPO-treated UT-7/GMT cells positively stained for Hb. Us...
متن کاملFunction of Neutrophils in Different Phases of Chronic Myelogenous Leukemia
In chronic myelogenous leukemia (CML), the mature granulocytes originate from a stem cell line harboring an abnormal chromosome, therefore it is possible that metabolic-functional abnormalities occur in the morphologically mature cells. In the present study, the phagocytic activity including intracellular killing, nitro blue tetrazolium (NBT) reduction, and phagocytosis were studied in 37 CML p...
متن کاملFlow Cytometry in Chronic Myelogenous Leukemia Blast Crisis
Background: Chronic myelogenous leukemia (CML) is a myeloproliferative disorder due to BCR-ABL1 translocation. Patients showing transformation into blast crisis (BC) have poorer treatment response and prognosis. Methods: A retrospective study was conducted in the department of Pathology, Maulana Azad Medical College, New Delhi, India, over a time period of 5 years (2014-2019) to evaluate the ...
