  • 简介:目的将在对待matrine的K562房间上调查CGI-100-击倒的K562房间的特征和CGI-100RNA干扰(RNAi)的效果。指向CGI-100基因和与一个不同序列包含一样的核苷酸作文的一双否定控制的三oligonucleotides被设计并且化学上综合了的方法。由在K562房间的shRNA-CGI-100的CGI-100表示的抑制效率用semiquantitativeRT-PCR和点污点杂交被决定。K562房间的生长上的CGI-100RNAi的效果用MTT试金被检验,房间区别被不同途径包括流动cytometry,benzidine染色和电子显微镜测量。在CGI-100-konckdownK562细胞为48h与matrine的0.2mg/ml或hemin的30mol/L被孵化以后,GlycophorinA(GPA)(CD235a)和生长因素independence-1BmRNA(Gfi-1BmRNA)的表示层次被RT-PCR和GPA的蛋白质层次测量,CD14和CD15被流动cytometry检测。结果CGI-100RNAi的真核细胞的表示向量成功地被构造。K562/shRNA-CGI-100房间线在由shRNA-CGI-100的CGI-100基因表示的抑制效率在哪个是54%被建立。CGI-100-knockdown禁止了增长并且在K562房间导致了erythroid区别。与控制K562房间相比,K562/shRNA-CGI-100房间证明减少的吸收度价值由MTT试金,减少的enchromation,增加的heterochromation,G0/G1阶段房间的增加的百分比,S阶段房间的减少的人口,减少的PI(房间的增长索引),和benzidine积极的房间的提高的百分比检测了。而且,到matrine或hemin的K562/shRNA-CGI-100房间的敏感被提高,到matrine的这些房间的敏感对hemin比那高。与控制K562房间相比,在K562/shRNA-CGI-100房间的matrine处理导致了增长,benzidine积极的房间的提高的百分比,GPA和Gfi-1B的显然起来调整的mRNA表达式,和GPA的增加的吝啬的荧光紧张(MFI)的增加的禁止的率。没有CD14表示被检测,没有统计意义被作出对有利的裁决检测CD15。最后,在与hemin对待并�
