G1期和G2期是Gap phase英文名称的缩写形式，S期是Synthesis phase英文名称的缩写形式。G1期和G2期主要进行RNA和蛋白质的合成，S期主要进行DNA的合成。

②在S期之前,即前一次有丝分裂完成之后到S期开始之间的时期,称为第一间隙期（gap phase),简称G1期。③从S期结束后到有丝分裂开始之间的时期称为第二间隙期,即G2期.在G1期和G2期中,细胞不合成DNA,但损伤的DNA可在此时修复。④细胞进入G1期后,即开始为下一次分裂做准备.各种与DNA复制有关的酶...
Cells, however, aren't constantly replicating or preparing to replicate. The period of time in the cell cycle when neither is happening is known as the G0 phase. Figure 2. Overview of the cell cycle. G1, S, and G2 make up interphase. G0 can be thought of as extending from G1.View...
the repairing cells had significant increases in crystal adhesion capacity and cell proliferation as compared to the control. Cell cycle analysis using flow cytometry demonstrated that the repairing cells underwent cell cycle shift from G0/G1 to S and G2/M phases. Cyclosporin A (CsA) and hydroxyu...
细胞群内S期细胞比例可达72.3%,高侧向角,高前向角的细胞群内G2/M期细胞比例可 达42.8%.结论:应用流式细胞仪的光学参数可以有效同时分选,获得分别含有高比例 Go/G期,S期,G2/M期的细胞亚群. 【关键词]细胞周期流式细胞仪 Sortingofcellsub-fractionscontainingthehighpercentofG0/G1phase, ...
Quiescent β-cells exposed to a mitogenic glucose stimulation require 8 h to enter the G1 phase of the cell cycle, and this time is prolonged in older age. The duration of G1, S, and G2/M is ~5, 8, and 6 h, respectively. We further provide the first in vivo demonstration of ...
Confluent normal fibroblasts were exposed to X-rays or accelerated particles with different LET values and chromosome aberrations were investigated in the first G(0)/G(1) and G(2)//M phase. The particles used here were 490 MeV/nucleon Si, 500 MeV/nucleon Fe, and 200 MeV/nucleon Fe ions...
The first was an arrest of cells in G0G1, evidenced by an accumulation of cells in this phase and a concomitant reduction in the percentage of cells in the S-phase. The second was an arrest of cells in the G2M phase of the cycle. G0G1 and G2M arrest occurred within 24 h and ...
(A) HUVECs were treated with 20 μM RF, viable cells were collected by trypsinization, and DNA content was analyzed after PI staining. (B) The percentages of cells in G0/G1, S, and G2/M phase in three independent experiments (A) are expressed as the mean ± SD; *p < ...
