查询词典 peptide

As mentioned earlier, elastinolysiss thought to be an essential component of emphysema.3 This is supported by both pathophysiologic and biochemical investigations, which show reduced lung elastic recoil, disrupted elastic tissue structure, higher circulating levels of elastin peptide breakdown products, and higher levels of desmosine in urine and lung secretions.3 Of the macrophage-derived MMPs identified in emphysematous and COPD tissue, the gelatinases MMP2 and MMP9 are elastinolytic.

正如早些时候提及的，elastinolysiss被认为是肺气肿的主要成份之一。这可以由病理生理研究与生化研究所证实，这两项研究同时提示肺弹性活力的降低，弹性组织结构的断裂，弹力蛋白肽分解产物循环水平的增高，以及尿与肺脏分泌物中锁链素水平的增高。在气肿型或COPD组织中，经确定的巨噬细胞源性的金属蛋白酶中，elastinoly的MMP2与 MMP9是elastinolytic。

Thus,CMG-KALA nanoparticles have great potential as gene vectors for transfection in vitro.2.GS-peptide nanoparticles were synthesized as previous reported method in order to improve the ability of cell penetrating,endosome escaping and nuclear targeting.

通过激光共聚焦、荧光光谱以及红外光谱证明KALA可以成功地连接到CMG纳米颗粒表面；通过静电引力吸附将DNA与CMG-KALA纳米颗粒进行复合，并通过琼脂糖凝胶电泳证明该纳米颗粒对DNA具有很好的保护作用。

In theory, on entry into endosome of tumor cells immunoGrB protein releases C-terminal PE Ⅱ-GrBa into cytosol as a result of auto-cleavage of peptide bond between Arg279 and Gly280. Two kinds of PE translocating peptides covering 253-364 aa and 253-358 aa were compared for their endosome-disruptive function.

一方面，从瞬时表达、可诱导表达和组成性表达三方面研究证明，N端部分PE Ⅱ序列(PE 280-364 aa和280-358 aa)的存在基本不影响GrBa诱导转染细胞死亡的作用。

Secreted by the epithetical cells of animal thymus, Ta1 is widely distributed. It is an immunoregulatory peptide with multiple biological activities such as modulate cell-mediated immunity, anti-aging and anti- virus activity and so on.

它由动物胸腺上皮细胞分泌，在体内分布广泛，是一具有多种生物学活性的免疫调节剂，可调节细胞免疫功能，有较好的抗衰老和抗病毒作用等。

Complete acid hydrolysis of the peptide followed by amino acid analysis yielded equimolar amounts of Leu, Orn, Phe, Pro, and Val. Orn is ornithine, an amino acid not present in proteins but present in some peptides .

此肽完全水解，然后经氨基酸分析产生等摩尔的Leu，Orn，Phe，Pro和Val，Orn为鸟氨酸，是蛋白质中不存在而存在于某些肽中的一种氨基酸。

Aβ（β-amyloid peptide） induce neuronal cell damage by increasing the generation of ROS. Therefore, we further assessed the effects of test compounds on living cells. Esculetin was the most potent agent at protecting cells against Aβ induced cell cytotoxisity via inhibiting the generation of ROS or ROS scavenging among the tested coumarin derivatives.

由於Aβ肽造成神经细胞伤害涉及自由基的过度生成，因此我们将上述结构-活性关系结论进一步应用在活体细胞实验的表现，结果显示esculetin可以透过抑制自由基生成或自由基清除作用而降低Aβ所引发的细胞毒性。

The molecule of antibacterial peptide displays α-helical structure of amphipathicity, which can form the ion-channel to induce the death of pathogen on the protoplasmic membrane of bacterium, eumycete and parasite.

抗菌肽分子呈双亲性的α-螺旋结构可使细菌、真菌、寄生虫的质膜形成离子通道，从而导致这些病原体死亡。
