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。

It follows that the de-protonic reaction of hydroxide group for PVA had taken place in above solution, and the coordination group for deprotonic oxygen of PVA had produced more. These ligands interact with some Fe3+ of ferric hydroxide while the ferric hydroxide in new emergence is forming,causing the formation of Fe-PVA coordination polymer-the composition of the reddish brown resinoid substance.
推定PVA部分羟基在上述条件下发生脱质子反应而提供L-配位体,Fe盐水解生成初生Fe3的Fe3+,它既有空轨道,又有较强的正电场,故能吸引PVA高分子配位体L-上的氧而形成O→Fe配位键,从而发生L-与Fe3+离子间的交联反应,生成多核Fe-PVA配位聚合物而析出红棕色树胶状物。

The analyses of social and economic development indicate that, up to 1998, the total population in Yijinholo County is 143, 949 persons, the population density is 24 persons per square kilometer, large population number results in land exploitation for food and overgrazing in rangeland. The change in temporal and spatial pattern of landuse from 1977 to 1998 demonstrates that mobile sand dunes was replaced by rangeland and woodland and partial shrubland in the middle of study area changed into rangeland and farmland from 1977 to 1987, while mobile sand dunes and rangeland transformed into shrubland and farmland in a small parts from 1987 to 1998, the above-mentioned change is proved by the change of fractal dimension index and fragmentation index at landscape and its element levels.
对近50年来伊旗社会经济发展的分析结果表明,虽然人口增长率基本上呈下降趋势,但由于人口基数较大,截至1998年底,伊金霍洛旗的人口总数达143949人,人口密度为24人/平方公里,较高的人口密度带来了更多的生存需求,使得大量的草牧场被开垦,而剩余的则严重超载。1977-1998年间伊土地利用结构总体格局变化的分析结果表明,1977-1987时段内主要是流动沙地为草牧场和乔木林地所取代,伴随着中部的部分灌木林地转换为草牧场和农地:而1987-1998时段内主要是草牧场和流沙地为灌木林地和农地特别是灌木林地所取代,而景观及各景观要素的分维度指数和破碎度指数的变化也充分证实了这一结论,虽然在前10年(1977-1987年)中大面积的灌木林被砍伐,但土地利用格局的整体变化间接地反映出该时段内荒漠化的状况正在发生逆转。
