为了鉴定具有细胞衰老诱导活性的染色体,将带有可选择标记基因(Neo)的正常人2、3、6、7、9、11或12号染色体通过微细胞介导的染色体转移导入人宫颈癌细胞系SiHA。通过2号染色体转移获得的G418抗性克隆中,76%(158/207)表现出明显的形态变化(细胞扁平),其中93%(147/158)在6-9群体倍增之前停止分裂(衰老),而通过转移其他染色体获得的克隆大多具有与亲本细胞相似的形态并继续生长。染色体分析表明,逃脱衰老的细胞只含有一小段来自转移的2号染色体的片段,而在大多数持续生长的微细胞杂交中,转移的染色体显然是完整的,并引入了其他染色体。这些结果表明,正常人类2号染色体携带一个或多个基因,可以在SiHA细胞中诱导细胞衰老。
For identification of the chromosome carrying cellular senescence‐inducing activity, normal human chromosome 2, 3, 6, 7, 9, 11, or 12 tagged with a selectable marker gene (neo) was introduced into the human cervical carcinoma cell line SiHa via microcell‐mediated chromosome transfer. Seventy‐six percent (158/207) of the G418‐resistant clones obtained by the transfer of chromosome 2 showed a remarkable change in morphology (cells were flat), and 93% (147/158) of them ceased to divide (senesced) prior to 6–9 population doublings, whereas most of the clones generated by the transfer of other chromosomes exhibited a morphology similar to that of the parental cells and continued to grow. Chromosome analyses suggested that cells which escaped from senescence contained only a small fragment derived from the transferred chromosome 2, whereas the transferred chromosomes were apparently intact in most of the continuously growing microcell hybrids with introduction of other chromosomes. These results indicate that the normal human chromosome 2 carries a gene or genes that induce cellular senescence in SiHa cells.
