查询词典 Gene

A number of nucleic acid repair genes such as excision repair cross-complementing gene 1(ERCC1) and human xeroderma pigmentosum gene D(XPD/ERCC2),the level descent may be susceptible factors to one or certain kinds of tumors; but if these genes′ level are higher,the ability to repair damage and chemotherapy-induced genetic damage will be enhanced,it may be resistance to chemotherapeutic drugs.

一些核酸修复基因，如切除修复交叉互补基因1(ERCC1)及人类着色性干皮病基因D(XPD/ERCC2)的水平下降，可能会成为某种或某几种肿瘤的易感因素；但如果此种基因的水平较高，修复损伤的能力提高，对化疗药物所致基因损伤的修复能力也就增强了，那么可能对化疗药物产生耐药现象。

成功地将epsps基因构建到酵母胞内表达载体pPIC3.5K和植物表达载体PBI121上，利用电击法转化酵母及农杆菌介导法转化烟草，转基因酵母在草甘膦压力下筛选出耐受性较好的菌株，标记为ATME-4-M和ATME-9证明了所获基因具有生物学功能。

The purpose of the experiment is to realize the prokaryotic expression of β-glucosidase gene from Acetobacter xylinum ATCC 23769, which will be used to produce enzyme preparation so as to develop the efficiency of extracting resveratrol from plants. Aspergillus niger β-glucosidase gene is cloned both at DNA lever and cDNA lever, which will lay a foundation for further research about its expression in Saccharomyces cerevisiae in a secretory form with the aim of increasing resveratrol contents in wines.

本实验实现了木醋杆菌β-葡萄糖苷酶基因的原核表达，目的是为了生产粗酶制剂，用于提高从植物中提取白藜芦醇的得率；分别在DNA和cDNA水平从黑曲霉中克隆β-葡萄糖苷酶基因，为下一步在酿酒酵母中实现分泌表达以提高葡萄酒的白藜芦醇含量的研究奠定基础。

The number of differentially expressed genes was 71 at 24h, and 62 at 72h. The metabolisic gene class was the majority among all the differentially expressed genes, and the next was transportational、differentiation and adhesional gene class by turns.1.2. RT-PCR verification of the known HIF-1 targeted genes and proliferation related genesIn the 131 differentially expressed genes, we found 7 known HIF-1 targed genes (ldha、aldoa、eno1、gapdh、tpi1、pgk1、bnip3) and 5 genes (dnaja2、ccnb1、tgfβ2、ccng1、rgs7) which were related to proliferation and cell cycle.

对差异表达的基因进行基因功能分类发现：代谢类基因最多，其次是运输类基因、细胞分化及黏附类基因。1.2 RT-PCR验证HIF-1靶基因和增殖相关的基因由于我们的前期实验证明了低氧促NSC增殖是有HIF-1参与的，我们对131个差异表达基因中，7个已知的HIF-1靶基因(ldha、aldoa、eno1、gapdh、tpi1、pgk1、bnip3)和5个与细胞周期和增殖相关的基因(dnaja2、ccnb1、tgfβ2、ccng1、rgs7)做RT-PCR验证。
