ARID (AT-rich interaction domain) protein is a transcription factor family in higher eukaryotes that regulates cell proliferation, development, and differentiation. Specificity of DNA binding ability in this family prefers AT-rich sequences, but some ARID family proteins are not sequence-specific DNA-binding proteins or they do not bind AT-rich sequences. We found two genes that encode ARID in Giardia lamblia genome database, garid1 and garid2. We analyzed the function of garid1 first. AU1-tagged gARID1 was found to localize to nuclei. During encystation, gARID1 mRNA level decreased emphatically, but protein level increased. We also found that gARID1 can bind AT-rich initiator of the cwp1 promoter by EMSA. Mutation analysis revealed gARID1 binding sequence was AGATC and AATAAAATA. We used ChIP to demonstrate that gARID1 can bind cwp1 gene promoter in vivo.

ARID(AT-rich interaction domain)蛋白质家族是真核生物的一种转因子，在许多同种的真核生物有它的同源基因，这个家族的蛋白质通常与调控细胞的生长、发育和分化的作用有关，而这个家族的蛋白质和DNA的结合能，各种ARID蛋白质的专一性尽相同，过大致上偏好於和AT-rich的序结合；我们已经在形鞭毛虫的基因组中找到个含有ARID 的基因，分别是garid1和garid2，我们首先对於garid1做分析；将AU1标记接到gARID1转染形鞭毛虫，用免疫萤光染色可发现gARID1存在於细胞核中。gARID1的讯息RNA在囊体化后会明显下，过其阳性染色和蛋白质表现有明显增加；EMSA实验中也发现gARID1会明显的与cwp1基因启动子之AT-rich initiator结合，经由突变序分析，也显示gARID1的结合序为AGATC和AATAAAATA，随后我们也用ChIP证明gARID1在细胞内也的确会和cwp1基因的启动子结合。

After the identification of SARs in Attacus ricini rRNA gene, its rRNA gene and NTS were also found to have the ability binding with the nuclear scaffold of Saccharomyces cerevisiae. The 1kb NTS fragment which can bind clearly with nuclear scaffold of Attacus ricini was the chief fragment binding with yeast nuclear scaffold. This indicated the homology between this two kinds of SARs and provided an evidence for the evolutionary conservation of SARs.

在鉴定蓖麻蚕rRNA基因中具有骨架结合区域之后，利用体外结合的方法发现，蓖麻蚕rRNA基因及其非转录间隔区片段也具有与酵母核骨架结合的能力，尤其是能与蓖麻蚕核骨架结合的非转录间隔区1kb片段，也能明显地结合于酵母核骨架，这一结果表明二者的SAR顺序具有一定的同源性，为骨架结合区域具有进化保守性提供了又一证据。

Three major clusters of numt sequences ( cyt b numt、 ATP8+ATP6 numt and ND4+ tRNA-His+ tRNA-Ser numt) were particularity amplified and sequenced from 10 species within Galliformes and A.galericalata. Comparison numts sequences with homologous mitochondrial partial genes get the different evolutionary characteristics and evolutionary speed compared to mtDNA, then examine the age of insertion of numts using the sequence divergence of numt from the mtDNA. Finally, joined Coturnix japonica、 Coturnix chinensis、 Lophura leucomelana、 Lophura swinhoii and A.albifrons mitochondrial sequences in GenBank, we study the importance function to phylogenetic research of mitochondrial genes and homologous numts.The evolutionary rate of Numts is lower than their authentic sequences of mtDNA, cyt b and ND4 gene evolve faster than homologous numts 2.5 times; ATP8+ATP6 gene evolve faster than numts 18.9 times in Galliformes. Numts show less codon position bias and transition bias under not phylogenetic pressure.

E. , ACTH antagonizes the analgesia mediated byμand δ opioid receptors, but notκreceptor;(2) The antagonizing effect of ACTH on opioid analgesia is proposed to be mediated by ACTH receptors, although the latter has not been characterized;(3) A contradictory interaction on intracellular cAMP content may constitute one of the postreceptor mechanisms underlying ACTH antagonism of opioid analgesia;(4) Another proposed mechanism of the anti-opioid effect of ACTH is that ACTH can modulate opioid-induced suppression of calcium influx;(5) ACTH has been shown to induce Fos protein expression in selected areas of the rat brain including the nuclei involved in pain regulation as well as the ependyma of the third ventricle and the aqueduct.

根据以上实验结果，本论文首次提出以下论点：（1）ACTH在脊髓水平对抗阿片镇痛具有受体选择性，即ACTH可对抗μ受体和δ受体介导的镇痛，不对抗κ受体所介导的镇痛；（2）由于ACTH与阿片μ受体的肽类配体的结合位点仅有很低的亲和力，与μ受体的非肽类配体的结合位点以及δ受体无亲和力，推测ACTH是通过中枢内的ACTH受体介导发挥抗阿片效应的；（3）ACTH抗阿片作用的受体后作用机制之一是在cAMP信使通路水平与阿片发生相互作用；（4）ACTH抗阿片作用的另一受体后机制是在〓水平影响阿片的效应；（5）通过Fos蛋白的诱导揭示：ACTH可以作用于脑内多个核团，其中包括许多与痛觉调制有关的核团，推测ACTH可能通过激活这些核团的神经元而发挥其中枢效应。
