Truncation mutations in the adenomatous polyposis coli protein are responsible for familial and sporadic colonic tumours. Except for its function as a role in regulating b-catenin, recent studies show that APC has additional roles in cytoskeletal regulation. It binds to microactin and microtubules directly and indirectly. Furthermore, APC plays an important role in mediating the detraction of chromosome.

编码APC蛋白(adenomatous polyposis coli， APC)基因的缺失突变会导致家族性和散发性的结肠癌，APC蛋白除了能直接参与Wnt信号途径调节b-catenin的浓度之外，最近的研究表明APC蛋白能够与细胞骨架的主要成分微管和微丝直接或间接结合，通过调节微管的解聚和聚合，间接调节染色体的分离，作为潜在的细胞骨架调节分子将细胞骨架与重要的细胞信号转导通路紧密联系在一起。

The macropolarity of diaspore surfaces is high, and the adsorbed layer formed in such a manner is sporadic.

2 STR-PCR We analysed the results of STR with the silver dye in the beginning. The silver dye of STR analysis on a sporadic DMD family shows the band confirmation is subjective by eyeballing. It can not detect the small repeats and the size of polymorphic fragments. For limitation of the silver dye, we analysed the band size of STR with the SAGAGT Genotyping System. Primer are designed according to the nucleotide sequence of five STR markers (located in 5' terminus and intron 44, 45, 49, 50) of dystrophin gene. The 5' end of the forward primer are attached a M13 tailed primer which conjugated to the infrared flourescent dye.

根据dystrophin基因5个多态位点（44、45、49和50号内含子以及5'端启动子区的序列）设计引物，在这些STR的上游引物5'端加一可被红外线荧光物质IRDye700识别标记的M13fw的尾：CAC GACGTT GTA AAA CGA C 通过PCR扩增出重复序列本身，经高分辨率的变性聚丙烯酰胺凝胶电泳后，利用红外激光遗传分析系统及SAGA〓基因分型软件对凝胶上的扩增产物及内标的位置，进行扫描分析，确定产物片段的大小。

Under Gregory VII the pope's legates traversed France from north to south, they convoked and presided over numerous councils, and, in spite of sporadic and incoherent acts of resistance, they deposed bishops and excommunicated princes just as in Germany and Spain In the following two centuries Gallicanism is even yet unborn; the pontifical power attains its apogee in France as elsewhere, St. Bernard, then the standard bearer of the University of Paris, and St. Thomas outline the theory of that power, and their opinion is that of the school in accepting the attitude of Gregory VII and his successors in regard to delinquent princes, St. Louis, of whom it has been sought to make a patron of the Gallican system, is still ignorant of it -- for the fact is now established that the Pragmatic Sanction, long attributed to him was a wholesale fabrication put together (about 1445) in the purlieus of the Royal Chancellery of Charles VII to lend countenance to the Pragmatic Sanction of Bourges.
