Gamma-linolenic acid induces apoptosis and lipid peroxidation in human chronic myelogenous leukemia K562 cells.
Various polyunsaturated fatty acids, especially gamma-linolenic acid (GLA), inhibit the growth of a variety of tumor cells. Some evidence indicates that polyunsaturated fatty acid can kill cells by apoptosis. In the current study, we tested the apoptotic effect of GLA on human chronic myelogenous leukemia K562 cells. GLA induced K562 cell death in a dose-dependent manner. Typical apoptotic nucl...
متن کاملRelationships between multidrug resistance (MDR) and stem cell markers in human chronic myeloid leukemia cell lines.
The K562 cell line (chronic myeloid leukemia), sensitive to chemotherapy (non-MDR), and the Lucena cell line, resistant to chemotherapy (MDR) were investigated. The results suggest that both cell lines possess CD34+CD38- profiles of hematopoietic stem cell markers. The promoter regions of ABCB1, ABCG2 and ABCC1 genes contain binding sites for the Oct-4 transcripton factor, which is also conside...
متن کاملTuberostemonine reverses multidrug resistance in chronic myelogenous leukemia cells K562/ADR
Objective: To investigate the reversal effect of tuberostemonine on MDR in myelogenous leukemia cells K562/ADR. Methods: Human myelogenous leukemia cells K562 and their adriamycin-resistance cells K562/ADR were used. The growth curve of cells treated by tuberostemonine and the Non-toxic concentration of tuberostemonine were determined by MTT, Cell apoptosis was determined by MTT and flow cytome...
متن کاملQuantitation of doxorubicin uptake, efflux, and modulation of multidrug resistance (MDR) in MDR human cancer cells.
P-glycoprotein (Pgp), a membrane transporter encoded by the MDR1 gene in human cells, mediates drug efflux from cells, and it plays a major role in causing multidrug resistance (MDR). Confocal microscopy was used to study in vitro and in vivo drug accumulation, net uptake and efflux, and MDR modulation by P-glycoprotein inhibitors in MDR1-transduced human MDA-MB-435mdr (MDR) cancer cells. The M...
متن کاملChronic Myelogenous Leukemia: Approaches to Pharmacological Resistance
From 2000 some data relative to IM resistance were available. There are many mechanisms responsible of IM resistance, more often point mutations that cause the progression to blast crisis and death in few months. To circumvent them, more potent TKIs have been subsequently approved [3]. However, another problem arise: these compounds don’t work on all patients because of the different IMresistan...
