摘要: 目的 研究重组腺病毒(rAV)介导报告基因绿色荧光蛋白(GFP)能否转染到大鼠肾脏组织,以及多种途径转染的差异。 方法 30只大鼠随机分成5组,经5种途径注射rAV-GFP(1013个病毒颗粒·L-1)溶液,注射后2、7和14d,分别取各组大鼠的左肾、右肾、肝脏和肺脏,荧光显微镜观察,并通过计算机软件评价报告基因在肾脏组织中的表达情况。 结果 各种注射方式均可使绿色荧光蛋白在肾脏中表达,注射后7d时GFP表达达到高峰,并以腹腔和尾静脉注射方式表达最强;经肾动脉注射的靶向性较其他方式好。 结论 rAV载体能携带报告基因到肾脏组织,rAV可以用于肾脏疾病的基因治疗,且各种注射方式各有优缺点。

Abstract: Objective To investigate expression of recombinant adenovirus(rAV) vector-mediated report gene in kidney, and seek for the best way of rAV vector-mediated gene transfer in vivo. Methods Thirty Sprague-Dawley(SD) rats were divided into 5 groups randomly. rAV-GFP(1013viral particales·L-1 ) was injected through different ways. 2, 7 and 14d after injection, the GFP expression in left kidney, right kidney, liver and lung was evaluated by fluorescence microscope and computer software. Results GFP gene expressed in kidey and 7d after injection expression reach peak, through intraperitoneal and caudal vein injection expressions were most; through renal artery has the best target. Conclusion rAV vector-mediated report gene could be transducted in kidney. The rAV-mediated transgene expression in kidney is a potential strategy in treatment kidney diseases and different ways have their own characteristics.
