They can divide about 50 times before they self destruct in a process called apoptosis.

在它们分裂大约五十次时就会以细胞凋亡的形式自我毁。

These granules contain some molecules that punch holes in the target cell's membrane by binding by binding directly to the phospholipids and creating pores. and some that cause target cells to undergo apoptosis, which is a programmed cell death.

这些颗粒内含些能在靶细胞膜上打孔的分子，它们直接与磷脂结合，然后穿孔；还有些能够导致靶细胞凋亡，即程序性细胞死亡。

HHV-8 expresses a viral antigen called LANA-1 which prevents apoptosis and facilitates uncontrolled cellular proliferation.

Eventually though, over the course of years, chondrocytes aren't able to keep up, and they become exhausted, and can undergo apoptosis, or programmed cell death.

最终，随着时间推移，软骨细胞力不从心，开始凋亡或程序性细胞死亡。

When the old bone tissue is cleaned out, the osteoclasts then undergo apoptosis, where they basically self-destruct before they can do any more damage.

当旧的骨组织被清除后，破骨细胞会发生凋亡，在造成更多伤害之前，它们基本上会自毁。

So when LANA-1 inhibits p53, that prevents apoptosis and leads to uncontrolled cellular proliferation.

所以当LANA-1抑制了p53的活性时，这会阻碍细胞凋亡并导致细胞增殖失控。

The other portion damages the membrane, triggering a mechanism called apoptosis which causes the cell to kill itself.

另部分能破坏细胞膜，产生种让细胞死亡的机制。

BCL-2 normally blocks cell death, or apoptosis, so overexpression of the bcl-2 gene prevents the cell from dying.

BCL-2通常会阻止细胞死亡或凋亡，所以BCL-2基因的过度表达会阻碍细胞凋亡。

To balance out cell growth, there are other genes called tumor suppressor genes which promote apoptosis or cell death of mutated cells.

为平衡细胞生长，还有其它基因，称作抑癌基因，促进突变细胞的凋亡或细胞死亡。

Rituximab is a monoclonal antibody that binds CD20 and induces complement-mediated lysis, as well as direct cytotoxicity and apoptosis.

And that process is called apoptosis is actually really really important.

这个过程被称为细胞凋亡，实际上非常重要。

And at the same time, they downregulate things related to immune inflammation, basically hiding from the immune system, and apoptosis, which is programmed cell death.

与此同时，它们会下调与免疫炎症相关以及程序性细胞死亡（即细胞凋亡）相关的基因，从而基本上躲避免疫系统的监视。

They found that an important weapon in the elephants Arsenal is TP-53 a gene that encodes an apoptosis inducing protein called P-53.

他们发现大象武器库中个重要武器是TP-53基因，该基因编码种名为肿瘤蛋白p53的诱导细胞凋亡的蛋白质。

When cells amass too much damage, they usually notice and special genes trigger a controlled  suicide called apoptosis.

But apoptosis or cell death is super important in that regulation.

但细胞凋亡或细胞死亡在调控中极为重要。

And finally, those cytokines activate the executioner, the natural killer cells, which then induce apoptosis, that programmed cell death, in the cancer cells.

最后，这些细胞因子激活了执行者——自然杀伤细胞，进而诱导癌细胞发生程序性细胞死亡（即凋亡）。

Histologically, in tissues stained with hematoxylin and eosin, apoptosis involve single cells or small clusters of cells.

凋亡细胞表现为具有致密核染色质片段的、胞质强嗜酸性染色的圆形或椭圆形团块。
