HIF-1α通过调节多种基因的表达来调节细胞对低氧的适应性反应，是迄今为止发现的唯一的一个在缺氧状态下发挥特异性活性的调节分子，被认为是调节缺氧相关基因表达的关键分子，它同激活蛋白(activated protein 1， AP-1)，核转录因子(nuclear factorκB， NF-κB)和p53等协同作用调节机体对缺氧的反应，其功能涉及能量代谢、细胞增殖、造血作用、血管形成、重塑与收缩等诸多方面。

The Taohezhenwu Decoction has good curative effect in treating and preventing CRF of rats induced with adenine by improving the renal function, electrolyte disturbances, acid-base equilibrium, hemophthisis and the function of SOD, reducing the harm of NO, TNF-α, and lessening or delaying the deterioration of nephron.

桃核真武汤能改善腺嘌呤大鼠慢性肾衰模型的肾功能、调节电解质酸碱平衡紊乱、纠正贫血、减少尿蛋白的丢失、减少NO与TNF-α损伤、提高SOD的保护作用、一定程度上防止肾单位的恶化，对SD大鼠腺膘呤所致之CRF的防治有肯定的疗效。

In this dissertation, several recombinant unlabeled as well as 15N- or 15N/13C-labeled proteins were expressed and purified in large quantities. We then carried out circular dichroism and heteronuclear multidimensional NMR experiments to gain insight into the structure-function relationships on these proteins, as described below.

在本篇论文里，我们表现并纯化出大量所欲探讨的重组蛋白质，利用碳-13与氮-15同位素来标定这些重组蛋白，以旋光光谱及异核多维核磁共振技术来探讨这些蛋白质的结构与其功能的相关性，内容如下

In addition, baculovirus are noninfectious to vertebrates, and their promoters have been shown to be inactive in mammalian cells. Futhermore, the expression level of some recombinant proteins is up to 1000 mg/L. Finally, recombinant proteins are soluble and antigenically, immunogenically and functionally similar to their authentic counterparts. In this article, we used the transfer vector pBlueBac of AcNPV (Autographa californica Nuclear Polyhedrosis Virus) to construct the recombinant baculovirus AcNPV-GM-CSF by in vivo recombinantion.

本文中，我们首先利用苜蓿夜蛾核型多角体病毒带β-Galactosidase 基因标记的非融合蛋白基因转移载体pBlueBac，通过细胞内同源重组的方式将hGM-CSF基因成功地插入病毒AcNPV的基因组中。hGM-CSF基因编码信号肽和完整的氨基酸序列。hGM-CSF基因在感染重组病毒的草地夜蛾培养细胞Sf9中得到表达，感染后的Sf9细胞培养液能刺激人骨髓细胞在体外形成典型的集落，表达水平可达2.7〓CFU／ml。

A new eucaryotic expression system of recombinant PoIFN-γ was also constructed so that the denaturalization and refolding process is avoided. The target gene coding PoIFN-γ2 mature protein was subcloned into expression vector, transformed into Pichia pastoris, The His〓 Mut〓 phenotype transformants were screened, fermented in flasks and induced by 1％methanol. The expressed product in culture solution and sedimentation have antiviral activity on VSV and immunological activity proved by indirected immunofluorescence antibody and Dot blotting assay.

为了构建可对表达产物修饰、加工的真核表达系统，使表达产物具有自然干扰素的活性，无需变性、复性，我们将PoIFN-γ2成熟蛋白基因连接酵母整合表达载体，电转化毕赤酵母，筛选了His〓Mut〓表型转化子，摇瓶培养，1％甲醇诱导表达，培养上清和菌体裂解上清均有抗VSV病毒活性，经间接免疫荧光抗体检测和Dot blotting鉴定，重组酵母菌诱导表达产物具有免疫活性。

The near isogenic lines, Ps and Pf, were developed by anther, which serves as materials for isolating and cloning Rf3 gene by using of two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) we had improved in this study.
