利用复制缺陷腺病毒(RDAd)进行基因转移有望治疗血管增殖性疾病,但这些病毒感染多种细胞系的能力可能会受到限制。我们已经生成了一个RDAd载体,命名为AdSM22-lacZ,它在平滑肌细胞(SMC)特异性SM22alpha启动子的转录控制下编码细菌lacZ报告基因。在体外实验中,我们发现AdSM22-lacZ可调控lacZ报告基因在大鼠主动脉内皮细胞和A7r5细胞中的表达,但在人脐静脉内皮细胞(HUVECs)或NIH 3T3细胞中不表达。与这些结果一致的是,在控制和球囊损伤的大鼠颈动脉动脉内给予AdSM22-lacZ后,在中膜和新内膜的SMCs中检测到β -半乳糖苷酶活性,但在内皮细胞或外膜细胞中检测不到。此外,静脉注射AdSM22-lacZ不会导致肝脏或肺中lacZ基因的表达。最后,我们已经证明,将AdSM22-lacZ直接注射到含有smc的组织中,如输尿管和膀胱,可以在内脏smc中产生高水平的转基因表达。综上所述,这些结果表明,RDAd载体感染后的转基因表达可以通过使用含有SMC特异性SM22alpha启动子的转录盒以SMC谱系限制的方式进行调节。针对SMCs的高效基因传递系统的演示提供了一种在体内限制重组基因产物在血管或内脏SMCs中的表达的新方法。
Gene transfer using replication-defective adenoviruses (RDAd) holds promise for the treatment of vascular proliferative disorders, but is potentially limited by the capacity of these viruses to infect multiple cell lineages. We have generated an RDAd vector, designated AdSM22-lacZ, which encodes the bacterial lacZ reporter gene under the transcriptional control of the smooth muscle cell (SMC)-specific SM22alpha promoter. Here, we show that in vitro AdSM22-lacZ programs expression of the lacZ reporter gene in primary rat aortic SMCs and immortalized A7r5 SMCs, but not in primary human umbilical vein endothelial cells (HUVECs) or NIH 3T3 cells. Consistent with these results, after intraarterial administration of AdSM22-lacZ to control and balloon-injured rat carotid arteries, beta-galactosidase activity was detected within SMCs of the tunica media and neointima, but not within endothelial or adventitial cells. Moreover, intravenous administration of AdSM22-lacZ did not result in lacZ gene expression in the liver or lungs. Finally, we have shown that direct injection of AdSM22-lacZ into SMC-containing tissues such as the ureter and bladder results in high-level transgene expression in visceral SMCs. Taken together, these results demonstrate that transgene expression after infection with an RDAd vector can be regulated in an SMC lineage-restricted fashion by using a transcriptional cassette containing the SMC-specific SM22alpha promoter. The demonstration of an efficient gene delivery system targeted specifically to SMCs provides a novel means to restrict expression of recombinant gene products to vascular or visceral SMCs in vivo.
