Differential binding of conA and WGA on the cell surface,the role of sialic acid in their expression and the increased activity of sialidase after cis-Platin treatment

Summary It is reported that concanavalin A (conA) and wheat germ agglutinin (WGA) have a differential binding pattern on normal mouse spleen lymphocytes and the surface of Dalton's lymphoma cells. It is suggested that sialic acid on the cell surface controls the expression of lectin binding sites. Further, it has been observed that the increased release of sialic acid from cell surfaces aftercis-dichlorodiammine platinum (II) (cis-Platin) treatment is due to the increased activity of sialidase.To whom reprint requests should be addressed.

COM/CORBA互操作中的对象标识及绑定研究

随着ＣＯＭ和ＣＯＲＢＡ的迅速推广使用，用户迫切需要ＣＯＭ／ＣＯＲＢＡ互操作系统以实现ＣＯＭ和ＣＯＲＢＡ应用的集成，因此很多ＣＯＲＢＡ产品都遵照ＯＭＧ组织的ＣＯＭ／ＣＯＲＢＡ互操作规范提供了互操作的功能。然而规范中的对象标识及联编机制还存在问题，导致应用程序无法在不同的互操作系统上移植，而且在通用映射实现方式中，无法按照规范中定义的机制实现ＣＯＲＢＡ客户对ＣＯＭ对象的联编。文中提出了一种统一的对象标

The short C-terminal hydrophilic domain of NhaH Na~ /H~ antiporter from Halobacillus dabanensis with roles in resistance to salt and in pH sensing

The Na /H antiporter plays key roles in maintaining low cytoplasmic Na level and pH homeostasis,while little is known about the Carboxyl-terminal hydrophilic tails of prokaryotic antiporters.In our previous study,the first Na /H antiporter gene nhaH from moderate halophiles was cloned from Halo-bacillus dabanensis D-8 by functional complementation.A topological model suggested that only nine amino acid residues(395PLIKKLGMI403) existed in the hydrophilic C-terminal domain of NhaH.The C-terminal truncated mutant of NhaH was constructed by PCR strategy and designated as nhaH△C.Salt tolerance experiment demonstrated that the deletion of hydrophilic C-terminal nine amino acid resi-dues significantly inhibited the complementation ability of E.coli KNabc,in which three main Na /H antiporters nhaA,nhaB and chaA were deleted.Everted membrane vesicles prepared from E.coli KNabc/nhaH△C decreased both Na /H and Li /H exchange activities of NhaH,and also resulted in an acidic shift of its pH profile for Na ,indicating a critical role of the short C-terminal domain of NhaH antiporter in alkali cation binding/translocation and pH sensing.     

人类基因组中L1元件及其5＇UTR的研究

讨论了L1在人类染色体中的分布密度与染色体长度以及L1的密度与基因密度之间的关系．发现在大多数染色体上L1的密度和染色体的长度表现为正相关，而L1的密度和染色体中基因的密度表现为负相关；对人类L1的5’UTR进行了详细的研究后，发现在L1元件的5’UTR部分含有许多转录因子结合位点．对基因的转录起始位点上游进行统计分析，发现其中含有大量的L1序列．通过对人类的EST数据库进行BLAST分析，新发现了51条和人类L15’UTR相似性较高的EST片断，根据它们分布的组织特异性，说明L1元件可能调控与发育过程有关的基因的表达；最后应用多样性增量的方法对人类和大鼠的L1 5＇UTR进行了区分，得到了较好的预测结果，说明大部分L1的5’UTR的调控作用是人类特有的．
