RNA synthesis was studied at different phases of the cell cycle of chick embryo fibroblasts, which were synchronized by medium replacement in the confluent phase. The synthesis of DNA started at 4 hr and continued for 8 hr. RNA synthesis increased with time after medium change. The ratio of ...
in different cell cycle phases of NB4 cells might determin the selective induction of G2/M apoptosis and the cells' susceptibility to apoptosis by As2O3... Fei,Gao,Jing,... - 《Cell Research》 被引量: 159发表: 2004年 Cell cycle regulation of the c-Myc transcriptional activation domain. ...
The basic machinery that detects DNA damage is the same throughout the cell cycle. Here, we show, in contrast, that reversal of DNA damage responses (DDRs) and recovery are fundamentally different in G1 and G2 phases of the cell cycle. We find that distinct phosphatases are required to ...
(P23-286) Computerized video time lapse (CVTL) analysis of human EJ30 cells x-irradiated in different phases of the cell cycle.Leonhardt, Edith
The distribution of cell cycle had been analysed by Multi Cycle software (Flow Systems of Phoenix, San Diego, CA) and various phases of cell cycle occupied by different percentage of cells, namely G0/G1, S, and G2/M, was calculated. Three independent experiments were done and the data ...
cell. We studied fresh specimens from 50 cases of primary breast cancer. The expression of topo IIα in different cell cycle phases was analyzed with two-parameter flow cytometry using the monoclonal antibody SWT3D1 and propidium iodide staining. The expression of topo IIα was significantly ...
The radiosensitizing effect of 5 and 30 mM of Ro-07-0582 (misonidazole) has been studied at different stages of the cell cycle of mitotically selected NHIK 3025 cells under aerobic and extremely hypoxic conditions. For cells irradiated under aerobic conditions no sensitizing effect was seen at...
Detailed procedures are presented for obtaining highly enriched human Daudi cell population in different cell cycle phases. This protocol allows harvest of enriched G 1 or S-G 2 phase cells based on the recognition of a cell surface marker antigen by anti-CD11 a antibody and sorting. Sorted ce...
A multiprotein unit has been identified in human complexes, termed DREAM whose composition is regulated at distinct phases of the cell cycle [16]. The core DREAM complex contains Lin9, Lin37, Lin54, Lin52 and RbAp48 (the human homologues of Drosophila Mip130, Mip40, Mip120, dLin52 and...
Thus, the better capability of rats for time perception and conditioning on the basis of time perception in transitional phases of a day (from light to darkness and on the contrary) is in agreement with circadian rhythm of locomotion of these nocturnal animals. 展开 ...
