文中指出,韵核前滑音在结构上属声或属韵并不能由与音节首辅音的组合型态得知,但是此语言的重音规则显示韵核前滑音应带音拍,因此在结构上应与韵核较为接近。

In this study, the genomic structure and regulatory elements of ApoD from 10 representive species including protozoan, invertebrate, protochordate and vertebrate were analyzed and compared. The genomic structure of ApoD is less conserved in organisms from protostome to deuterostome invertebrates, while it is highly conserved among chordates including amphioxus and verebrates. All four conserved cysteine residues are present in amino acid sequence of deuterostome ApoDs, while there are only two cysteine residues in amino acid sequence of protostomes ApoD. Structure divergence between protostome and deuterostome ApoD proteins suggests their function difference. The majority of regulatory elements are present in nearly all organism ApoD genes ranging from unicellular protozoan to mammals, suggesting that ApoD plays a very fundamental role, and possesses a conserved regulatory mechanism. However, there also exist some specific regulatory elements, which are present only in certain species and may perform some special roles.ApoD mRNA expression in murine NIH/3T3 fibroblasts exposed to various stresses such as as hydrogen peroxide and UV light shows dose-dependent increase. And a fly homolog of ApoD, Glial Lazarillo, whose overexpression results in increased resistance to hyperoxia as well as a extension of lifespan under normoxia and resistance to starvation without altering lipid or protein content.

本文首先从生物信息学角度对分属于原生动物、无脊椎动物、头索动物和脊椎动物类群的10种动物ApoD的基因结构及调控区的调控元件进行分析及比较,发现:(1)ApoD基因外显子-内含子结构从原生动物草履虫到原口动物再到后口动物海胆的进化过程中不保守,但在分析的几种脊椎动物中相当保守;(2)文昌鱼ApoD基因扮演从无脊椎动物到脊椎动物承上启下的角色,可能代表了脊椎动物ApoD基因原型;(3)四个半胱氨酸保守位点在后口动物中都存在,而在原口动物中只存在两个,原口、后口动物ApoD蛋白一级结构上的差异反映蛋白功能上可能也存在一定差别;(4)调控区大多数主要调控元件为不同动物共有,说明ApoD主要功能及其表达调控在进化中相当保守;(5)ApoD基因个别调控元件是随着物种进化而出现并开始发挥相关作用,如SF-1;还有一些调控元件在进化过程中还没有发现其规律,这说明ApoD某些功能和基因表达调控模式可能因物种不同而存在一定的差异。

First, ab initio calculations have been performed at the HF/6-31G level of theory for 27 indazolyl urea compounds (using 1H-indazole tautomeric form). On the basis of optimized structures, five kinds of topological indices, electrostatic potentials as well as their statistically-drived quantities have been obtained.
