OxidativeStressInducedGeneExpressionViaNrf2
Reactive oxygen species (ROS) can damage biological macromolecules and are detrimental to cellular health. Electrophilic compounds, xenobiotics and antioxidants are sources of reactive oxygen species, creating oxidative stress that can harm cells. Enzymes are involved in the Phase II detoxification of xenobiotics to reduce cellular stress include glutathione transferases, quinone reductase, epoxide hydrolase, heme ox......阅读全文

实验中的氧化损伤氧化应激(Oxidative-Stress,OS)
氧化应激(Oxidative Stress,OS)是机体活性氧成分与抗氧化系统之间平衡失调引起的一系列适应性的反应。干扰细胞正常的氧化还原状态,会制造出过氧化物与自由基导致毒性作用,因此损害细胞的蛋白质、脂类和核酸。发生在人类的氧化压力,被认为是造成亚斯伯格症候群、自闭症、阿兹海默症、帕金森氏症

克隆基因的表达(expression-of-cloned-gene)1
基因表达(gene expression)是指储存遗传信息的基因经过一系列步骤表现出其生物功能的整个过程。典型的基因表达是基因经过转录、翻译,产生有生物活性的蛋白质的过程。基因的表达主要涉及到两个过程:转录和翻译。 第一节影响外源基因表达的因素 利用基因工程技术高水平表达
克隆基因的表达(expression-of-cloned-gene)2
在双链 DNA 分子中,只有一条链转录成 mRNA,这条链称为有意义链(sense strand),该基因的另一条链则称反意义链(antisense strand)。在含有许多基因的 DNA 双链中,每个基因的有意义链并不是在同一条 DNA 链上。也就是说,一条链上既具有某些基因的有意义链,
