evaluation of effect of as2o3 on cell growth, cell cycle and apoptosis in human leukemia cell line hl-60
introduction : arsenic trioxide (as2o3) causes antitumor effects by various mechanisms, including degradation of pml-rara in the acute promyelocytic cells, growth inhibition and induction of apoptosis. however, the precise mechanisms of these processes remain incompletely understood. the purpose of this study was to evaluate the effects of arsenic trioxide on cell growth, cell cycle regulation ...
متن کاملProliferation of mitochondria during the cell cycle of the human cell line (HL-60)
Using rhodamine 123 to stain mitochondria of the human cell line HL-60, we have followed their increase over the cell cycle by flow cytometry. A near-linear synthesis of mitochondrial mass was shown to occur over the cell cycle. A comparison with the cell's DNA synthesis pattern obtained by the same technique established a common time-base. The mitochondrial synthesis curve changes with culture...
متن کاملComparative toxicosis of sodium selenite and selenomethionine in lambs.
Excess consumption of selenium (Se) accumulator plants can result in selenium intoxication. The objective of the study reported here was to compare the acute toxicosis caused by organic selenium (selenomethionine) found in plants with that caused by the supplemental, inorganic form of selenium (sodium selenite). Lambs were orally administered a single dose of selenium as either sodium selenite ...
متن کاملCaffeine prevents apoptosis and cell cycle effects induced by camptothecin or topotecan in HL-60 cells.
Caffeine (3,7-dihydro-1,3,7,-trimethyl-1H-purine-6,6-dione; CAF) is known to potentiate the cytotoxic effects of DNA damaging agents such as ionizing radiation and alkylating agents. In contrast, however, the cytotoxic and cytostatic activity of aromatic, DNA-intercalating, DNA topoisomerase II inhibitors such as Adriamycin, ellipticine, or mitoxantrone are diminished in the presence of CAF. To...
متن کاملDifferences in cell cycle kinetics during induced granulocytic versus monocytic maturation of HL-60 leukemia cells.
Leukemia cells (HL-60) were induced to mature towards granulocytic and monocytic phenotypes using 1.1% dimethyl sulfoxide and 5 X 10(-7) M 1-beta-D-arabinofuranosylcytosine, respectively. Granulocytic maturation was accompanied by a slight decrease in cell volume and in total cell protein, but with an increase in acid phosphatase. DNA histograms showed that after 7 days there was a decrease in ...
