查询词典 chlorine peroxide

To study the applicable prospect of suicide gene on tumor therapy in clinic,we cloned the gene of D-amino acid oxidase and the gene of yeast cytosine deaminase.We hope to establish the transgenic mices of DAAO gene and YCD gene,and the two transgenic strain mices are valuable animal system for studying the biological characteristic of DAAO gene and YCD gene ,for studing the killing activity of DAAO/D-Ala and YCD/5-FC gene therapy systems on tumor.The D-amino acid oxidase gene derived from R.gracilis and it could oxidize D-amino acids. Hydrogen peroxide(H2O2) is a reactive oxygen species generated in the deamination of D-Ala catalyzed by DAAO.

为了探讨自杀基因在临床肿瘤治疗中的应用前景，建立自杀基因肿瘤治疗评价的动物模型，我们克隆了D-氨基酸氧化酶(D-amino acid oxidase，DAAO)基因和酵母菌胞嘧啶脱氨酶(yeast cytosine deaminase，YCD)基因，希望建立DAAO基因及YCD基因转基因小鼠，为研究DAAO及YCD基因的生物学特性、开发和评价DAAO／D-Ala及YCD／5-FC自杀基因系统进行肿瘤治疗建立良好的实验动物模型。
