Mimosine, a non-protein amino acid, is mainly known for its action as a reversible inhibitor of DNA replication and, therefore, has been widely used as a cell cycle synchronizing agent. Recently, it has been shown that mimosine also induces apoptosis, as mainly reflected in its ability to elicit
Taxol, an antineoplastic drug, increases the fraction of cells in G2/M phases of cell cycle, induces apoptosis of leukemic cells, and activates macrophages to produce nitric oxide (NO) in response to interferon-gamma. NO has been found to play roles as pro-apoptotic or anti-apoptotic effector
The effects on the cell cycle of two biologically active compounds, bistratene A and cycloxazoline, from the marine ascidian Lissoclinum bistratum were studied in HL-60 human leukemia cells using flow cytometry. Both compounds were shown to cause an apparent accumulation of cells in the G2/M phase.
The efficiency of retinoic acid (RA)-induced differentiation was dependent on the position of HL-60 cells in the cell cycle. Our results demonstrated that cells at the G1/S border were more efficiently induced to differentiate by short exposure to RA than cells at other phases of the cell cycle.
The effects of three compounds on the cell cycle of HL-60 promyeloid leukemia cells has been examined. Ciclopirox olamine, an antifungal agent, and the compound Hoechst 768159 reversibly block the cell cycle at a point occurring roughly 1 h before the arrest mediated by aphidicolin, an inhibitor of
Aberrantly high expression of EVI1 in acute myeloid leukaemia (AML) is associated with poor prognosis. For targeted treatment of EVI1 overexpressing AML a more detailed understanding of aspects of spatiotemporal interaction dynamics of the EVI1 protein is important. EVI1 overexpressing SB1690CB AML
