多肽

ET and NO are the biology regulatory factors produced by vascular endothelial cell.ET is a peptide with vasoconstrictive and vasodilator effect produced by endothelial cells,and NO as a powerful endothelium-derived relaxing factor,has a strong role in dilation of blood vessels.

ET和NO是血管内皮细胞产生的生物调节因子，ET是由内皮细胞产生的一种多肽，具有缩血管和扩血管作用，而NO为一种强有力的血管内皮细胞舒张因子，具有强烈扩张血管作用。

Endothelin-1 (ET-1) is a potent vasoconstrictive peptide that was isolated initially from the conditioned medium of cultured endothelial cells. It is a pathogenic mediator with a number of deleterious effects, including vasoconstriction, fibrosis, vascular hypertrophy,and inflammation.Atrial natriuretic peptide, angiotensin II and nitric oxide also takes an important role in cardiovascular system.

内皮素-1(endothelia-1，ET-1)是一种由内皮细胞合成和分泌的、具有强烈收缩血管作用和促进细胞增生的血管活性多肽，心钠素(atrialnatriuretic peptide，ANP)、血管紧张素Ⅱ(angiotensin Ⅱ，AⅡ)、NO等在心血管系统功能的调节中也起着重要作用。

Results: pcDNA3.1+/TSP-1-Ⅰ veinal injection has stronger TSP-ltype Ⅰ repeat band than that of directly injection into myocardium (P＜0.05), while veinal injection of pcDNA3.1-/anti-TSP-1-Ⅰ has a slightly weak TSP-1 typeⅠ repeat band (P＜0.05), Western blot obtained the same result.

成功构建pcDNA3.1+/TSP-1-Ⅰ、pcDNA3.1-/anti-TSP-1-Ⅰ。作为血管新生抑制基因，在体外，TSP-1Ⅰ型重复序列基因编码的TSP-1Ⅰ型重复序列多肽，能够抑制ECV304细胞生长和增殖，其抑制机制与TSP-1Ⅰ型重复序列诱导ECV304细胞凋亡相关。

There were soluble trophic molecules with relative molecular weight larger than 30 000 for survival and neurite growth of FMN cultures in media with SC-CMCs derived from facial and sciatic nerves of neonatal rats and with SC-CMCs derived from Wallerian degenerating facial and sciatic nerves of adult rats. It might be reasonable to choose SC from sciatic nerves of rats on account of the findings from SC cultures on facial motoneurons.

面神经和坐骨神经SC-CMC中含有促FMN存活、生长的蛋白或多肽，相对分子质量大于30 000，其活性作用与使用的蛋白浓度有关；在研究SC分泌物对FMN营养活性作用时，可考虑选择坐骨神经SC。

Histone H3 is one of the four histones, along with H2A, H2B, and H4, which form the eukaryotic nucleosome octamer core. In this study, a new gene RH3.2A encoding an H3.2-type histone H3 protein from rice (Oryza sativa L.) was reported. RH3.2A was cloned through RT-PCR from salt-treated rice seedlings.

本研究从盐胁迫处理的水稻幼苗组织中分离了一个新的水稻组蛋白H3基因RH3.2A，编码具有136个氨基酸残基的多肽，与多种植物的组蛋白H3蛋白具有高度的氨基酸一致性。

Analysis of ORF and coden usage indicated that there was a ORF with 639bp and coding 212 amino acids in the 200p, and a preference for particular synonymous codons.

开放阅读框和密码子偏好性分析显示200p有一个639bp的开放阅读框，编码一条有212个氨基酸的多肽，其密码子的使用具有明显的偏好性。

The method was validated for acetylated peptides and allowed an assessment of even the basal protein phosphorylation of phenylalanine hydroxylase in intact cells.

该方法被确证乙酰酶多肽，并允许在不完整细胞中对苯丙氨酸羟化酶的基本蛋白质磷酸化的评估。

Use enzyme to disintegrate soybean into small molecule polypeptide, which has the function of debasing cholesterol.

大豆用酶解成小分子多肽，具有降低胆固醇作用。

One of the aspects of protein folding is the folding mechanism which concerns with the question of how a protein reaches its native structure from its denatured state.

蛋白质折叠中的一个重要问题是研究蛋白质的折叠机制，即研究蛋白质是如何由一个变性的多肽链状态到达其天然的三级结构的。

The group of mixture dieted albumin polypeptide with 3H-TdR was compared with the groupdieted only 3H-TdR in mice.

应用同位素示踪法对小鼠小肠、肝及胸腺等组织的3H-胸腺嘧啶核苷(3H-TdR)放射性值进行检测，比较了白蛋白多肽和3H-TdR混合物进食组小鼠与仅进食3H-TdR组小鼠间的区别。
