The human erythroleukemia (K562) cell line is induced to differentiate into megakaryocytic cells by treatment with the tumor promoter phorbol myristate acetate (PMA). PMA-induced differentiation is characterized by (1) almost complete cessation of cellular proliferation, (2) expression of the megakaryocytic cell surface marker glycoprotein IIb/IIIa (gpIIIa), (3) increased secretion of granulocy...
The widespread occurrence of AU-rich elements (AREs) in mRNAs encoding proteins with diversified functions and synthesized under a vast variety of physiological conditions suggests that AREs are involved in finely tuned and stringent control of gene expression. Thus it is important to investigate the regulation of ARE-mediated mRNA decay in a variety of mammalian cells in different physiologica...
background: chronic myeloid leukemia is a common cancer in human and chemical therapy is a routine method for treatment that has some side effects. so the goal of this study was the use of natural compound such as cell wall obtained from saccharomyces cerevisiae ( s. cerevisiae ) and saccharomyces boulardi ( s. boulardi ) and iron nanoparticles on the growth inhibition of k562 cell line. method...
Ouabain has shown powerful anti-proliferation activities in various cancers, but its effect on imatinibresistant chronic myeloid leukemia and toxicity normal mice not been investigated. Cell Counting Kit-8 assay was used to detect cytotoxicity reversal of ouabain with different concentration (0.01 μM, 0.1 1.0 10 μM) drug resistance imatinib-resistant cell line (K562/G01 line). Flow cytometry th...
We analyzed the binding of fibronectin to integrin alpha 5 beta 1 in various cells; in some cells fibronectin bound with low affinity (e.g., K562 cells) whereas in others (e.g., CHO), it bound with high affinity (Kd approximately 100 nM) in an energy-dependent manner. We constructed chimeras of the extracellular and transmembrane domains of alpha IIb beta 3 joined to the cytoplasmic domains of ...
BACKGROUND Leukemia seriously threatens human life and health. MicroRNAs can regulate cell growth, proliferation, and death. This article investigated the role of miR-29 on regulating leukemia cell growth, proliferation, and apoptosis. MATERIAL AND METHODS miR-29 and scramble miRNA were transfected to K562 cells. MTT assay, colony formation assay, caspase-3 activity detection, and flow cytome...
Human chronic myelogenous leukemia-blast crisis K562 cells have been demonstrated to be relatively resistant to antileukemic drug-induced apoptosis. This has been attributed to the activity of p210bcr-abl tyrosine kinase present in the K562 cells, which is known to suppress drug-induced apoptosis. Recently, K562 cells have been shown to express the antiapoptosis Bcl-xL but not Bcl-2 proteins. T...
Here, we have utilized six new anti-human beta 5 monoclonal antibodies to perform a detailed investigation of the structure, function and distribution of beta 5 integrins. Monoclonal anti-beta 5 specificity was confirmed by reactivity with beta 5-transfected CHO cells, by direct binding to the beta 5 subunit (immunoblotting), and by immunodepletion experiments using polyclonal anti-beta 5 serum...
Introduction: Chronic myeloid leukemia (CML) is a malignant clonal disorder of hematopoietic stem cells resulting in the increase of myeloid cells, erythroid cells and platelets in the peripheral blood and hyperplasia in bone marrow. The research evaluated the cytotoxic effects of hydro-alcoholic extracts of Lepidium Sativum (Cress plant) shoots before and after flowering on K562 cell line as a...
