Construction of the Model of Caloric Restriction Retarding Replicative Senescence with Human Diploid Fibroblast IMR-90

热量限制延缓人二倍体成纤维细胞衰老的体外模型

Therefore, normal human cells lack telomerase activity, their telomeric DNA lengths decrease gradually with the increasing numbers of cell divisions, eventually telomeres shortening induce cellular replicative senescence.

因此正常人体细胞缺乏端粒酶活性，端粒DNA长度随细胞分裂次数增多逐渐缩短，最终引起细胞复制衰老。

AIM To study the stimulatory effect on DNA synthesis and unscheduled DNA synthesis ( UDS) in splenic lymphocytes induced by low dose enriched uranium 235 U.METHODS By using 3 H-TdR incorporation assay technique, the DNA replicative synthesis of splenic lymphocytes stimulated by PHA and LPS was observed.

目的：研究了低剂量浓缩铀对脾淋巴细胞DNA合成和UDS的刺激效应。方法：运用3H-TdR掺入技术，观察了脾淋巴细胞在PHA和LPS刺激下的DNA复制合成。

Objective To observe the replicative senescence-related beta-galactosidase activity in cultured human retinal pigment epithelium ( RPE ) cells.

目的观察培养人视网膜色素上皮 ( RPE ) 细胞中复制衰老相关的β半乳糖苷酶活性.

The replicative HBV transgenic mice had provide an ideal animal model for the study on nosogenesis of HBV and anti-HBV drugs.

该复制型HBV转基因小鼠模型为研究HBV的发病机制研究以及抗乙肝药物开发研究提供了良好的实验动物模型。

Active network has strong vitality, which is self-replicative, self-regenerative, self-developmental and self-protective.

这种网络有强大的生命力，能自我复制，自我再生，自我发展，自我保护。
