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。

Transcriptional activity of ACL recombinants normalized by Renilla was significant difference with pGL3-Basic expect for construct -27 and -15 (P<0.01). Construct -919 contains highest activity. 3 times reduction of transcriptional activity from-919 to -679bp indicated that negative regulation factors located probably in this region. The activity started on construct -73 suggested the basal promoter activity was located within the -73 to +77bp region; Transcriptional activity of IDHβrecombinants was not significantly different between the recombinant -58 and pGL3-Basic. The activity started on construct -82, decreasing with the length of the fragment up to -164 in despite of a bit of fluctuation, and kept increasing from construct -164 up to -279. Thus, the basal promoter activity was located within the -82 to +16bp region, whereas the upstream 197bp conferred maximal transcriptional activity.
采用5'端缺失策略,结合启动子预测结果,分别构建了8个ACL基因和19个IDH3β基因启动子区重组子,将其转染猪PK15细胞系,并利用荧光素酶双报告基因系统检测了它们的活性,结果表明:在所构建的猪ACL基因5侧翼序列的8个重组子中,除pGL-ACL27和pGL-ACL15外,其它重组子的荧光素酶活性与阴性对照均达到极显著水平(P<0.01),表明它们均具有启动子活性,pGL-ACL919活性最强,到pGL-ACL679活性下降了将近3倍,说明从-919bp到-679bp区域可能存在负的调控位点,从pGL-ACL621到pGL-ACL73活性有小幅度下降,到pGL-ACL27活性降到与阴性对照水平无显著差异,表明维持该启动子的基本活性区域位于-73bp到+77bp之间;IDH3β基因启动子活性开始于pGL-IB82,然后虽然有些波动,但是活性一直下降直到-164bp处,之后活性又开始升高,直到-279bp处活性达到最高,这些表明维持该启动子的基本活性区域位于-82bp到+16bp之间,从-82到-279之间的179bp区域具有最高的启动子活性。

In an offical careen between pain and joy, SuShi have gone through all kinds of hardships and difficulties. From early smooth sailing to late overgrown with brambles; From fall of vigor and vitality in his youth to full of carefree and confidence in HangZhou provincial governor; From limitless patriotic emotion in MiZhou provincial governor to tranquil spirit world during the exile in HuangZhou、HuiZhou and DanZhou,under influence of above factors, his Ci written was obviously divided into three stages: first, major of early HangZhou Ci was composed of unworried languange; second, major of MiZhou Ci was composed of unrestrained languange; third, major of HuangZhou、HuiZhou and DanZhou Ci was composed of broad-minded languange. However, whether unworried, unrestrained or broad-minded, it underlyingly reflected SuShi's depression in life.
在宦海沉浮中,苏轼历经磨难,从刚开始的一帆风顺到后期的荆棘丛生,从少年时的万丈豪气到杭州刺使任上的明艳亮丽,从密州刺使任上的无限爱国热情到流放黄州、密州、儋州的逐渐平静的心灵世界,这些都影响到他的词作,使他的词作明显的分成了三个阶段:一是由早期杭州词为主体构成的明艳语,二是由密州词为主体构成的狂放语,三是由黄州词为主体构成的旷达语,但是,不管是明艳、狂放还是旷达,其中在深层次里都流淌着苏轼人生失意的苦泪。

My life and thoughts are always full of passion and contradiction. I jumped out from a remote village, and began to observe all kinds of cities with an insight of scanning, at the same time I was guided to predict and think my future. I also jumped out from the experiences and thoughs of England philosopher Rossell、Fance litterateur Bront、Taiwanee Liuyong and American Chinese Wangan and so on, and began to face and plan my life with an attitude of thinking deeply. I jumped out from a poor and near broken family too, and began to think of my expectation and responsibility to my yesterday and tomorrow families.

We have all been victimized at some point because of our gender, race, age, socio-economic status, and religion or lack thereof. Our first cry is slapped out of us as we are violently wrenched from the relative safety of the crimson universe deep within our mother's bodies. Born in blood and battered into breathing, life begins with brutality and baptizes with violence.
由于咱们的性别,种族,年龄,社会经济地位和宗教信仰,或者对这些的缺乏,咱们从某些点上看都是被捐躯着的当咱们被激烈地从咱们母亲体内深处深红世界的安全中扭出,咱们的熬头声啼哭被从咱们体内拍打出来在鲜血中出生、被猛击以至能呼吸,生命就这样由残忍开始,受暴力洗礼
