目的:利用酵母双杂交技术从均一化的人肾透明细胞腺癌c DNA文库中筛选与转录因子HOXA11相互作用的蛋白。方法:培养人肾透明细胞腺癌细胞
提取RNA
采用SMART技术制备均一化的人肾透明细胞腺癌c DNA文库。同时
聚合酶链反应扩增人HOXA11基因片段(1
8
46 bp)
将此基因片段重组入p GBKT7载体
构建诱饵质粒p GBKT7-HOXA11
经酶切和测序验证质粒构建正确。将诱饵质粒转化酵母菌AH109
检测其有无毒性与自激活作用。随后
利用酵母双杂交系统从c DNA文库中筛选与HOXA11相互作用的蛋白。对筛选到的阳性克隆进行回转验证以及测序分析。结果:成功构建了人肾透明细胞腺癌c DNA文库和p GBKT7-HOXA11诱饵质粒。在AH109酵母细胞中
该质粒无毒性、无自激活作用。酵母双杂交筛选获得了5个与HOXA11相互作用阳性克隆。结论:获得人肾透明细胞腺癌细胞中与HOXA11相互作用蛋白
为进一步研究HOXA11在个体发育以及癌症发生发展中的作用机制奠定了基础。
Objective:To screen proteins binding with HOXA11 from human renal clear cell adenocarcinoma c DNA library by yeast two-hybrid system. Methods:The RNA of human renal clear cell adenocarcinoma cell was obtained and then transformed into c DNA library using SMART technology. Simultaneously
the c DNA fragments of HOXA11(1-846 bp)were amplified by polymerase chain reaction and constructed into p GBKT7 vector as the bait plasmid. The bait plasmid was transferred into yeast AH109 strain. Its toxicity and autoactivation were tested. Subsequently
the c DNA library was screened with p GBKT7-HOXA11 as bait plasmid by yeast twohybrid system. Finally
the positive clones were sequenced and further analyzed. Results:Human renal clear cell adenocarcinoma c DNA library and bait plasmid p GBKT7-HOXA11 were constructed successfully. The bait plasmid has no toxicity or autoactivation in AH109.Five positive clones were obtained and validated. Conclusion:Proteins deduced to interact with HOXA11 are identified through yeast two-hybrid screening. These results help to elucidate the possible roles of HOXA11 in carcinogenesis and development.
