探讨细胞色素P450 17α-羟化酶／17，20裂解酶(CYP17)小干扰RNA对CYP17基因表达和多囊卵巢综合征卵泡膜细胞雄激素合成的抑制效果。

Objective To observe the expression of cytochrome Cand apoptosis-related gene Bax in hippocampus of posttraumatic stress disorderrats in order to investigate their effects and relationships.

目的 观察细胞色素C和凋亡相关基因 bax 在创伤后应激障碍大鼠海马神经元中的表达，探讨其在细胞凋亡中的作用及相互关系。

The oxidase system includes both membrane-bound and soluble cytosolic proteins. The primary feature of this enzyme is stimulus-dependent activation and which mechanism is the phosphorylation and translocation of a complex of cytosolic factors to the membrane, where they associate with a flavocytochrome enzyme.The fully assembled complex functions as an electron transport system,moving electrons from cytosolic NADPH to molecular oxygen to form superoxide anion（O2-）, which, along with subsequent reactive products called respiratory burst,exerts microbicidal and cytotoxic activities.

此氧化酶体系包括膜结合的和可溶的胞浆蛋白，其主要特征为依赖刺激而活化，机制为复合体的胞浆因子磷酸化并转位至膜，在这里与细胞色素酶相关联，组装完全的复合体在功能上作为一个电子转运体系，从胞浆NADPH转移电子给分子氧形成超氧阴离子（O2-），伴随着接下来的活性物质产生，也叫呼吸爆发，发挥抗菌和抗细胞毒素的活性。

Nitrogen deficiency makes phycochrome turn pinkor pale,seedlings become slim and single line for not capable oflongitudinal division.

氮缺乏的症状是细胞色素体颜色浅红，紫菜幼苗苗体细长，不能进行纵分裂，始终保持单列细胞状态。

Objective To study the effects of manganese on the expression of caspase-3 and cytochrome-c in the spermatogenic cells of rats.

目的 研究锰对大鼠生精细胞中半胱氨酰天冬氨酸酶－3(caspase-3)和细胞色素C(cytochrome-c)表达的影响。

In the study, a set of near isogenic lines of CMS-S, S-Mo17Rf3Rf3 and S-Mo17rf3rf3, were adopted, and TdT-mediated dUTP nick-end labeling, in situ immunolocalization of cytochrome c and DNA ladder assay were employed to study the programmed cell death process on cytology and DNA level. The microscope observation evidenced that tapetal cells of fertile anthers kept intact until microspores, and then were disintegrated on later developmental stage.

S型细胞质雄性不育系的一对近等基因系S-Mo17Rf3Rf3 和S-Mo17rf3rf3为材料，采用TdT介导的dUTP DNA末端标记、细胞色素C免疫原位杂交和DNA寡聚核小体片段电泳等方法，分别在细胞学水平和DNA水平上研究了玉米CMS-S小孢子败育的细胞程序性死亡过程。

Methods The disorder of myofibrils,swelling of mitochondria with broken cristae and decrease of cytochrome C oxidase activity caused by ADR were prevented by the administration of teapol.

结果 阿霉素所造成的大鼠心肌细胞肌原纤维排列紊乱、线粒体肿胀，嵴断裂及细胞色素C氧化酶活性降低，可明显地被抗氧化剂天力体保所防止。

It oxidizes cytochrome C and generates reactive oxygen species within mitochondria in response to oxidative stress.

在氧化应激信号的刺激下，p66Shc在线粒体内氧化细胞色素C产生大量活性氧，造成细胞的氧化损伤。

The full-length Bid is inactive. Cleaved by caspase 8,the carboxy-terminal portion of Bid then translocates to mitochondria and is sufficient to trigger cytochrome c release. This is the key regulatory step in apoptosis.

它具有可被caspase 8酶切调控、高效地诱导细胞色素c从线粒体泄漏到胞浆中的功能，从而在细胞凋亡中起着重要的作用，因而倍受人们的重视。

Upon induction of apoptosis by diverse stimuli, Bax undergoes a conformational change and translocates to mitochondria, where it oligomerizes and forms pores that allow the release of cytochrome c and other cytotoxic foctors.

在被不同刺激诱导后，Bax的构象发生改变并转移到线粒体上。在线粒体膜上，它形成低聚物并使线粒体膜形成孔，使细胞色素c和其它细胞毒性因子可以排出。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
