摘要 目的构建真核表达载体p BI-EGFP-Bach1,并检测其表达及对血红素氧化物(HO-1)表达的影响。方法将Bach1基因与质粒p BIEGFP连接构成重组质粒,RT-PCR法检测重组载体及HO-1在SMMC7721细胞中的表达情况,MTT检测细胞活性。结果 NheⅠ和MluⅠ双酶切以及PCR表明重组质粒p BI-EGFP-Bach1构建成功;RT-PCR显示转染重组Bach1 mRNA表达显著升高,同时HO-1的表达降低;MTT检测未转染组的IC50为0.15μg/ml,转染组的IC50为0.21μg/ml。结论构建了真核表达载体p BI-EGFP-Bach1,转染后Bach1能够在SMMC-7721细胞中表达并抑制了HO-1;MTT验证重组质粒能提高癌细胞对长春新碱(VCR)敏感性。
