目前对造成遗传不稳定的机转并不清楚、但一般认为当细胞进入有丝分裂(M phase)周期时、纺锤丝(microtubule)不正常的聚合、是造成染色体异常分离的主因。而染色体异常的分离则造成癌细胞遗传不稳定性。

The percentage of cells at G2/M phase was increased with the increasing of MeHg, and the 1/50 LD50 group had significant difference compared with control group (P<0.05).
采用流式细胞术检测,G2/M期细胞百分数增加,1/50 LD50染毒组时与对照组比较差异具有显著性(P<0.05)。
Conclusions Sulfide can significantly reduce the proliferation of ECV304, change the cell cycle distribution and arrest cells in G2-M phase where apoptosis may be induced.
结论舒林酸的硫化代谢产物能够显著抑制血管内皮细胞的增殖活性,改变细胞的周期分布,使细胞阻滞于G 2期,并可能在此期诱导其凋亡。
One detail that will play an important part in M&S achieving its target to make all stores carbon-neutral by 2012 is the pledge to phase out HFC gases in supermarket refrigeration.
M&S要实现其制定的到2012年所有店铺零碳排放(carbon-neutral),重要的措施是确保淘汰超市冰箱使用的HFC气体。
Not only don't I exist during Phase D,I'm not alive either.
不仅不存在,而且不存活。
So it seems we have to say I'm not alive during Phase D.
所以我们得说我在D阶段也不是存活着的。
