分子影像报告基因系统的研究进展

分子影像报告基因系统的应用使基因治疗从实验阶段逐渐走向了临床应用,为无创性监测治疗基因的表达及进行定量分析提供了方法学技术.目前研究最多、最成熟的仍是放射性核素报告基因系统,近年来磁共振报告基因系统和光学报告基因系统的兴起和发展,极大地丰富和完善了分子影像报告基因系统的内容,并且在与应用化学和分子生物学等多学科交叉合作的基础上,涌现出了很多新型的修饰或改良的报告基因和分子探针.该文主要概述各类报告基因系统的优缺点和发展趋势.

Advances in study of molecular imaging reporter gene systems

The use of molecular imaging reporter gene systems has allowed gene therapy to move from the laboratory to the clinical application, which provides methodology to monitor the expression of therapeutic gene noninvasively and achieve quantitative outcome in vivo. Recently, the radionuclide reporter gene still is the focus of many studies, but MRI and optical reporter gene have gradually played a important part in reporter gene systems. On the basis of combination of multi-subject, for example applied chemistry and molecular biology, more and more new modified reporter genes and molecular probes have spread out. This paper mainly introduces the advantages and disadvantages of reporter gene system and development trends.
