文昌鱼

ABSTRACT Amphioxus, a cephalochordate, is the closest living relative to vertebrate, and has been widely known as the most important animal to study the origin and evolution of vertebrates.

文昌鱼是介于无脊椎动物和脊椎动物之间的过渡类型，是研究动物进化和胚胎发育的典型材料。

At present, studies about function of ApoD expressed in vitro are still very little. A concentration-dependent manner of inhibition rate scavenging of hydroxyl radical and prevention nicking of the supercoiled DNA by recombinant BbApoD suggests that BbApoD probably takes part in antioxidation process in vivo widely.

目前，利用体外表达的ApoD蛋白直接测定其功能作用的研究还很缺乏，BbApoD重组蛋白对体外Fenton体系产生的羟自由基的抑制作用以及对DNA氧化损伤保护作用的浓度依赖性变化暗示了文昌鱼ApoD蛋白很可能也参与了体内的抗氧化过程。

It is highly likely that AmphiLysC is an enzyme with a combined function of digestion and bacteriolysis.

所以，我们推测文昌鱼C型溶菌酶可能执行消化和免疫双重功能。

"Chordate:any of numerous animals belonging to the phylum Chordata, having at some stage of development a dorsal nerve cord, a notochord, and gill slits and including all vertebrate s and certain marine animals, such as the lancelets."

脊索动物：包括所有的脊椎动物以及如文昌鱼之类的海洋动物的脊索动物门的大量动物中的任一个，在某些生长阶段有背部神经索、背索及鳃裂。

Animal taxonomists described as a "living fossil" of the amphioxus, in the shallow water near the 15 m isobath density of 1035 / m, think about with these "living fossils" with swimming in a region, which can not but make you feel shock.

被动物分类学家誉为"活化石"的文昌鱼，在浅海15米等深线附近密度达到1035尾／平方米，想想能够与这些"活化石"同在一个区域游泳，这不能不使你感到震撼。

Study the diversity of chordates: lancelet, tunicate, lamprey, chondrichthyans, ray-finned fish, amphibians, reptiles, birds, and mammals.

A2， B2， G3 研习脊索动物的多样性－文昌鱼、海鞘、八目鳗、软骨鱼、硬骨鱼、两栖类、爬虫类、鸟类及哺乳类。

The amphioxus GDF8/11 cDNA encodes a polypeptide of 419 amino acid residues that showed high homology with MSTNs of molluscan, teleostean, avian, and mammalian species and GDF11 of mammalian and zebrafish species.

文昌鱼GDF8/11 cDNA编码一个419个氨基酸的前体多肽，这个前体多肽与软体动物、硬骨鱼类、鸟类和哺乳动物的MSTN以及哺乳动物和斑马鱼的GDF11具有高同源性。

And its developmental expression pattern showed that AmphiRab23b was expressed in the differentiating neural plate and alimentary canal, as the same as the expression pattern of the homologous vertebrate genes, which suggested that AmphiRab23b may function in the development of nervous system and alimentary canal.

时空表达的研究结果进一步显示，AmphiRab23b基因在胚胎发育中的神经板和消化道中表达，与其脊椎动物同源基因的表达模式相似，这说明该基因可能对文昌鱼神经系统和消化道的发育有重要作用。

Of Adult amphioxus, GnRH2ir nerve cells located in the dorsal of telencephalon front tip ×260

成年文昌鱼头部纵切面，可见GnRH2ir 细胞在端脑背面后部，靠近中脑处，腹面有GnRH2ir 神经纤维

The young Branchiostoma belcheri found in the east area of Laizhou Bay was studied.

本文对莱州湾东部水域出现的文昌鱼幼体进行了初步调查。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
