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。

The nanoplex were smaller than the unmodified nHAP; thelipiodol/nanoplex emulsion, with the mean diameter at 75±11.8nm can disperse moreuniformly and be more soluble and stable, contrary to the unmodified nHAP and nanoplex Conclusion: Nanoplex/pDNA mass ratios greater than 15 had exhibited completepDNA absorption onto positive charged polyplex and pDNA protection from thedestruction of nucleinase in rabbit serum. Unmodified nHAP may can\'t induce effectivegene delivery.PartⅡThe construction of the recombint eukaryotic expressive vector ofwild-type human p53 and RbObjective: To construct the recombint eukaryotic expressive vector of wild-type humanp53 and Rb by utilizing the theory of molecular medicine.

结果nHAP颗粒本身大小小于100nm，但由于颗粒表面本身带负电，不能包括有效地结合及保护DNA；经Ca~(2+)修饰后，颗粒可带正电，可一定程度地结合和保护DNA，但聚合物本身的中性电与带负电的细胞膜结合，而且本身的颗粒则变地容易聚集而成为很大的颗粒，也不利于细胞的吞噬；经PLL修饰后，颗粒溶解性提高，直径变小，表面带正电，电泳结果显示PLL-nHAP颗粒可包括有效地结合和保护DNA免受兔血清的破坏，而且复合物表面的正电也包括有利于与细胞膜的结合与吞噬。

In order to escplore the new models of cultivating in school, the essay tightly connects cultivating with teaching and research activities, based on developing teachers vacational level by modern information technoledge. Besides, during the process of founding the system of trainning teachers in school, we decide on our cultive target—promote the element educational reform by school internet, combing the facts of different schools. The cultive contnet should suit measures to different conditions, trying to synthesise and stress its practical function. When carrying out the cultive plan, we should sum up different models and explain its essence, steps and function so that we make the best choice. As to evaluational methods, we can take varied evaluational ways, including self-evaluation and evaluating each other by combination of fixing quality and quantity. At last, it is very necessary to found a special organization in order to form cultive web, make entire standarization, pay attention to develop resource and provide cultive guarantee.
