Studies suggest that programmed cell death ( pcd ; cells that occur pcd have a strict morphological change called apoptosis ) occurs after tbi 程序性細胞死亡( programmedcelldeath , pcd )參與了神經細胞損傷的發病機制。細胞進行pcd通常經過一個嚴格的形態學變化被稱之為凋亡( apoptosis ) 。
For organs to form during embryonic development , some cells must commit suicide . without such programmed cell death , we would all be born with webbed feet , like ducks 對胚胎發育期間形成的器官來說，部分細胞必須自絕生路。如果沒有這種程序化細胞死亡，我們生下來都會像鴨子一樣有帶蹼的腳。
What is more , we found that normal huntingtin appears to keep neurons alive by halting the cascade of molecular events that usually leads to apoptosis , or programmed cell death 我們更進一步發現，正常的杭丁頓蛋白似乎能夠阻斷導致細胞凋亡（計畫中細胞死亡）的連鎖分子反應，因而維持細胞的存活。
Experts know that cancers spread in two separate ways ? by the uncontrolled proliferation of cells , and by their refusal to undergo normal , healthy , programmed cell death , or " apoptosis . 專家們知道腫瘤發展有兩種方式，通過不可控制的細胞增殖；通過它們拒絕進入正常的健康的程序性細胞死亡即凋亡。
Refers to programmed cell death is a form of cell death in which a programmed sequence of events leads to the destruction of cells without releasing harmful substances into the surrounding area 細胞程序性死亡是指細胞死亡的一種形式，它由程序次序控制導致細胞毀滅的現象的逐一發生，而不會對周遭環境釋放有害物質。
The research is detailed in the may 13 issue of the journal carcinogenesis . follow - up research not published in the journal indicates a possible reason for the difference . exercise enhances a process called uvb - induced apoptosis , which means programmed cell death 科學家進行的深入研究向人們表述了之所以會出現這種差別的一個可能的原因，即體育鍛煉增強了一個名為紫外線b誘發的細胞凋亡uvb - induced apoptosis的過程，細胞凋亡是程序性細胞死亡
Labeling tunel method . the cell ultrastructural changes were similar to apoptosis in animal cells : the apical meristemetic cells underwent the programmed cell death . this was first detected in the apex cells of apical meristem , while peripheral cells differentiated gradually into different parts of a floral bud . but all the cells in the floral bud were subjected to the pcd process before it developed into a complete flower . 140bp dna fragment was found to deposit in apical bud during the plant development . the most important role of caspase - 8 was detected by western blot , and the expression of the procaspase - 8 was time - related with the dna frgmentation and the transformation from vegetative to the reproductive growth . these results suggested that pcd was an active process during the differentiation of apical meristem , and the senescence observed in the apical bud was due to the pcd process 顯微超微結構研究表明，短日照條件下豌豆頂芽的衰老過程是從營養生長錐向花芽的轉化，而用dna原位末端標記tunel caspase - 8 western blot和140 bp dna片斷積累的試驗結果證明，轉化為花芽的整個生長錐細胞發生了編程性死亡pcd ，而且其最頂端部分細胞首先發生pcd ，而頂端周圍的分生組織細胞逐漸分化出花芽的各部分，但頂芽最后并沒有發育成為完整的花，所有細胞就都發生pcd ，從而頂芽衰老。
The paper summarizes research advances about the developments of somatic embryos in several conifers , which have appeared at home and abroad in recent years , mainly in the effects of medium components in tissue culture and aba on the development of somatic embryos , and cytology , programmed cell death , genes and protein composition related to the development of somatic embryos , and further discusses the developmental mechanisms of somatic embryos and the role of somatic embryos in genetic transformation system 本文綜述了近年來國內外有關裸子植物中幾種松杉類植物體細胞胚發育過程的研究報道，其中主要涉及培養基成分和脫落酸( aba )對體細胞胚發育的影響，以及體細胞胚發育在細胞學、細胞程序性死亡、相關基因和蛋白質組學等方面的研究進展，并進一步討論了松杉類植物體細胞胚的發育機理，以及體細胞胚在遺傳轉化系統中的作用。
Al toxicity - induced ultraweak luminescence ( ul ) , sister - chromatid exchanges ( sces ) , programmed cell death ( pcd ) in root tips of barley , al - resistant genetic engineering and the role of root border cells in al toxicity were studied respectively , in order to explore some new pathways for al toxicity , al - resistant mechanism and genetic improvement 大麥是鋁毒極為敏感的作物，本實驗以大麥為材料，開展了鋁毒誘導的根尖細胞超微弱發光、姐妹染色單體交換( sce ) 、細胞程序性死亡、耐鋁基因工程及邊緣細胞在鋁毒中的功能研究。試圖為植物鋁毒及耐鋁機制和遺傳改良研究探索新途徑。
The upr pathway in mammals links with several branches , including the increased transcription of a series of genes that encode folding - related proteins , the ubiquitous down - regulation of protein translation , programmed cell death mediated by chop and degradation of er - related proteins , etc . though somewhat independent , these branches do have multiple connections 哺乳動物細胞的upr通路涉及與折疊能力相關的一系列基因轉錄上調、蛋白質普啟蒙翻譯下降、 ghop介導的程序性死亡及內質網相關性蛋白降解等多個分支。這些分支雖有一定的自主性，但卻存在著千絲萬縷的聯系，因此其中某個支路上效應成分的改變，就可能會對整個upr通路產生影響，甚至影響細胞的命運。
