In both cases, with the mutant yeast cells and the mutant telomerase RNA, the cells were ageing prematurely, their "senescence" was speeded up.
在两种情况之下，变异的酵母细胞和变异的端粒rna，细胞都是生长的不成熟，它们的老化过程加速了。
Telomere and telomerase are the focus of modern biological study. There are close relationships among telomere loss and cell ageing, activation of telomerase, cell senescence and immortalization.
端粒和端粒酶是现代生物学研究的热点，端粒的缺失与细胞的衰老，端粒酶的活性与细胞的老化及癌化均有密切的关系。
Cellular senescence may contribute to the ageing of organisms, and is closely related to tumor suppression.
细胞老化可能促进生物衰老，并且与肿瘤发生受抑密切相关。
