异常DNA甲基化在癌变过程中是必不可少的,利用动物模型进行分析是很重要的。本研究的目的是建立能够控制DNA甲基转移酶Dnmt3b表达的转基因大鼠,并阐明Dnmt3b高表达是否会诱导恶性表型肿瘤。构建了能诱导大鼠Dnmt3b2表达的转基因基因。为了通用,我决定构建转基因小鼠,并将大鼠cDNA替换为小鼠cDNA。如果建立转基因小鼠,它将使我们能够评估诱导或抑制异常DNA甲基化的因素。
英文摘要
Aberrant DNA methylation is essential in carcinogenesis, and analysis using animal model is important. The aim of this study was to establish a transgenic rat that can control expression of DNA methyltransferase, Dnmt3b, and to clarify whether high Dnmt3b expression induce tumors with malignant phenotypes or not. The transgenes that can induce rat Dnmt3b2 expression were constructed. For universal use, I decided to construct transgenic mouse, and the rat cDNA was replaced by a mouse cDNA. If a transgenic mouse is established, it will enable us to assess factors that induce or suppress aberrant DNA methylation.
