转基因下游MAR在稳定转化的CHO细胞中对基因表达的调控作用
核基质结合区 CHO细胞 转基因 报告基因
2009/7/17
［目的］探讨转基因下游MAR在稳定转化的CHO细胞中对基因表达的调控作用。［方法］将PCR扩增得到的人β珠蛋白MAR插入到真核表达载体pCATG的下游，构建转基因表达盒3′端含MAR的表达载体。酶切鉴定正确后，转染CHO细胞，G418筛选出稳定转化的细胞株，ELISA分析转基因的表达水平，半定量PCR分析转基因相对拷贝数。［结果］结果表明，表达盒3′端含MAR序列能使转基因表达水平降低，其基因拷...

异源MAR介导外源基因与家蚕受精卵核基质的体外结合
MAR 核基质 体外结合
2008/1/9
以携带人β干扰素基因5′上游MAR(Matrix Association regions)的质粒pCL为载体, 在其BamHI位点上正向插入天蚕(Antheraea ramamai)丝素基因核心区Af6.8而构建成质料pMAC。通过质粒pMAC、pAy6.8和pCL与家蚕(Bombyxmori)受精卵核基质的体外结合及其比较分析发现,在体外异源MA R能有效地介导外源基因与核基质结合。这为MAR作...
植物的MAR及其对转基因表达的效应
植物 基质附着区 转基因表达
2008/1/4
与核基质结合的DNA序列称为基质附着区（matrix attachment regions，MARs），可提高转基因的表达水平并降低转基因在不同转基因系间的表达差异，因其在植物基因工程中的巨大应用潜力而引起了研究者的极大兴趣。对植物中MAR的研究尚处于早期阶段，本文综述了植物中MAR的分离鉴定、序列特征及MAR对植物中转基因表达的影响，并进一步讨论了MAR对转基因效应的可能机制。
摘要 为减轻逆转录病毒介导的外源基因的沉默 ,进一步提高逆转录病毒MFG载体介导的转移基因的表达 ,将人 β INF基因上游 80 0bp的核骨架基质结合区 (S MAR)分别反向和正向克隆至MFG载体 3′LTR上游 ,以egfp为报告基因观察S MAR对egfp基因表达水平以及对病毒滴度的影响 .结果显示 :反向和正向的S MAR在瞬时表达的情况都不能提高egfp的表达 ,但在稳定整合的情况下...
