Edelfosine (1-O-octadecyl-2-O-methyl-rac-glycero-3-phosphocholine; ET-18-OCH3), a membrane-targeting anticancer ether lipid drug has been shown previously in vitro to be capable of initiating oxidative processes in cells. Here we study two human leukemia cell lines (HL-60 and K562) that have different sensitivities to edelfosine; HL-60 cells are more sensitive than K562 cells. To determine whet...
Recent studies have shown that high miR-155 expression was associated with poor prognosis in patients with acute myelogeneous leukemia (AML). Furthermore, targeting miR-155 results in monocytic differentiation and apoptosis. However, the exact role and mechanisms of miR-155 in human AML remains speculative. HL-60 cells were treated with anti-miR-155 for 72 h. Cell growth and apoptosis in vitro ...
The HL-60 leukemia cell line derived from a human acute promyelocytic leukemia is stimulated to differentiate into macrophages within 24-28 hr after exposure to the phorbol ester, 12-O-tetradecanoylphorbol-13-acetate (TPA). We studied early alterations (within 90 min of exposure to TPA) in phosphatidylcholine metabolism in HL-60 cells and found that phosphatidylcholine synthesis by methylation ...
The Fas-mediated pathway has been implicated as an important cellular pathway mediating apoptosis in diverse cell types. We conducted studies to examine the susceptibility to Fas-mediated apoptosis of HL-60 cells treated with differentiation-inducing factors such as dimethyl sulfoxide (DMSO), retinoic acid (RA), and 1alpha, 25 dihydroxyvitamin D3 (VD3). Although the expression of Fas antigen (A...
Focal adhesion kinase (FAK) has an anti-apoptotic role in anchorage-dependent cells via an unknown mechanism. To elucidate the role of FAK in anti-apoptosis, we have established several FAK cDNA-transfected HL-60 cell lines and examined whether FAK-transfected cells have resistance to apoptotic stimuli. FAK-transfected HL-60 (HL-60/FAK) cells were highly resistant to apoptosis induced with hydr...
AIM To investigate whether granulocyte-macrophage colony-stimulating factor (GM-CSF) with or without thalidomide can induce apoptosis and differentiation of HL-60 acute promyelocytic leukemia cell line in vitro. METHODS Effect of GM-CSF and thalidomide on proliferation of HL-60 cells was evaluated by MTT assay, cell cycle analysis was performed by propidium iodide staining approach and flow c...
The purpose of this study was to examine the effect of ethanol on apoptosis of human promyelocytic leukemia cell line HL-60 cells and search for a possible reason for reduced PMNs, monocytes, lymphocytes in the blood of alcoholics. Human promyelocytic leukemia cell line HL-60 cells was used as a model of apoptosis, with ethanol being the interfering factor. Qualitative and quantitative detectio...
Dioscin, extracted from the root of Polygonatum zanlanscianense pamp, exhibits cytotoxicity towards human myeloblast leukemia HL-60 cells. Proteomic analysis revealed that the expression of mitochondrial associated proteins was substantially altered in HL-60 cells corresponding to the dioscin treatment, suggesting that mitochondria are the major cellular target of dioscin. Mitochondrial functio...
Norcantharidin (NCTD) is the demethylated form of cantharidin, which is the active substance of mylabris, and is known to have anticancer potentials. The aim of this paper was to assess the apoptosis-inducing effect of NCTD on HL-60 cells. Methods. The effects of NCTD were detected by flow cytometer on the cell toxicity, cell cycle, and apoptosis of HL-60 cells cultured in vitro. Results. After...
