项目摘要
To develop the system to study gene function at tissue level in medaka, we have established two methods in the present study. 1) Reverse genetics : TILLING(Targeting Induced Local Lesions IN Genome) is a reverse genetic strategy that combines random chemical mutagenesis with high-throughput discovery of induced mutations in the target genes. The method has been applied to a variety of plant and animal species. Screening of induced mutation is the most important step in TILLING. We developed the High Resolution Melting(HRM) assay, evaluated its efficacy for screening ENU-induced mutations in the medaka TILLING library. The HRM assay is fast, cost-effective, and robust in detecting variations in DNA. By HRM assay many nonsense mutations were identified and the phenotypes of these nonsense mutants confirmed their loss-of-function nature. 2) Regulation of gene expression in tissue : Infrared laser. evoked gene operator(IR-LEGO) is a microscope system optimized for heating cells at single cell level. Heat stress induces transcription of genes that are under the control of a heat shock promoter in individual targeted cells. We applied this technique to medaka fish carrying a heat shock promoter driven transgene and have succeeded the control of ectopic gene expression.
为了开发在组织水平上研究青鳉基因功能的系统,我们在本研究中建立了两种方法。 1)反向遗传学:TILLING(Targeting Induced Local Lesions IN Genome)是一种反向遗传策略,它将随机化学诱变与高通量发现靶基因诱导突变相结合。该方法已应用于多种植物和动物物种。诱导突变的筛选是TILLING中最重要的一步。我们开发了高分辨率熔解 (HRM) 测定法,评估了其在青鳉 TILLING 文库中筛选 ENU 诱导突变的功效。 HRM 检测快速、经济高效,并且在检测 DNA 变异方面稳健。通过HRM测定,鉴定出许多无义突变,并且这些无义突变体的表型证实了它们的功能丧失性质。 2) 组织中基因表达的调节:红外激光。诱发基因操作器 (IR-LEGO) 是一款针对单细胞水平加热细胞而优化的显微镜系统。热应激会诱导单个靶细胞中受热休克启动子控制的基因转录。我们将该技术应用于携带热休克启动子驱动转基因的青鳉鱼,并成功控制了异位基因表达。
