Core--Animal

本核心的目的是为项目1、2和3提供各种转基因和敲除突变体。这个转基因动物核心项目的一个特别优势是，陈博士（核心负责人）将为其他项目提供他的专业知识，包括在转基因和敲除突变小鼠中使用超氧化物歧化酶，以及与氧自由基相关的生物化学和分子生物学。此外，陈博士还将提供他在啮齿动物神经元、星形胶质细胞和内皮细胞的原代细胞培养方面的专业知识。该中心将作为一个集中的设施，用于建立、表征和质量控制这些原代细胞培养的野生型动物，以及SOD1和SOD2转基因和敲除突变小鼠。该中心还将提供基因表达的分子分析（PCR, RT-PCR），凝胶电泳，CuZnSOD和MnSOD的酶活性以及小鼠和原代细胞培养的生化分析方面的专业知识。最后，该Core将分别为项目1和项目2产生双转基因/敲除（SOD1 +/-/ Sod2 -/+）和双敲除（PARP1 -/-/ Sod2 -/+）小鼠并进行表征。因此，转基因动物核心为项目提供了一个独特的载体，利用各种转基因和敲除动物来实现研究目标。

The purpose of this Core is to make available various transgenic and knockout mutants for Projects 1,2, and 3 of the program. One particular strength of this Transgenic Animal Core is that Dr. Chan (Core Leader) will provide his expertise to the other projects in the use of superoxide dismutases, in both transgenic and knockout mutant mice, as well as oxygen radical-related biochemistry and molecular biology. In addition, Dr. Chan will provide his expertise in primary cell culture of neurons, astrocytes and endothelial cells from rodents. This Core will serve as a centralized facility for setting up, for the characterization and the quality control of these primary cell cultures form wild-type animals, as well as SOD1 and SOD2 transgenic and knockout mutant mice. This Core will also provide expertise in the molecular analysis of gene expression (PCR, RT-PCR), gel electrophoresis, enzymatic activity of CuZnSOD and MnSOD and biochemical assays in mice and in primary cell cultures. Finally, this Core will generate and characterize the double transgenic/knockout (SOD1 +/-/ Sod2 -/+) and double knockout (PARP1 -/-/ Sod2 -/+) mice for Projects 1 and 2, respectively. Thus, the Transgenic Animal Core provides a unique vehicle for the projects to achieve the research goals employing various transgenic and knockout animals.
