摘要
本研究采用DNA重组技术及PCR方法对人甲胎蛋白(AFP)基因顺式调控元件+29bp至-5.1kb区进行改造,将改建的DNA片段分别克隆到荧光素酶报告基因载体pGL2-Basic中,构建了6种含有AFP基因增强子和/或沉寂子不同组合的载体。以期筛选出对人肝癌细胞特异的,具有强启动活性的AFP顺式调控元件组合,为进一步实行肝癌基因治疗提供依据。
sing recombinant DNA techniques and PCR method.we have arneliorated the 5.1 kb 5'- flanking region of the human a-fetoprotein(AFP)gene containing transcription control elements with characteristics of enhancers and silencers.and got six DNA fragments of different length that were cloned into luciferase expression vector pGL2-Basic.Hepatoma-specific transcription-regulatory sequences of the human AFP gene were expected to be obtained.
