NDUFS2: A Target Enabling Package

The molecular role of NDUFS2 in mitochondrial metabolism is through its participation in complex I of the respiratory chain within the inner membrane of mitochondria. Complex I function is critical for mitochondrial ATP production, but is also involved in reactive oxygen species production. As a core component of complex I, NDUFS2 resides within two hypotheses of opposing mechanisms with the potential to foster AD pathology: AD Hypometabolism Hypothesis and the AD Oxidative Stress Hypothesis. Each hypothesis is subordinate to a separately identified biological domain (mitochondrial metabolism and oxidative stress). Consequently, decreasing complex I integrity via down-regulation of NDUFS2 could either promote or decrease the propagation of AD pathology. The primary aim of this project is to generate resources to more effectively study the role of NDUFS2 in AD pathogenesis, through the generation of a basic TEP suite of resources, including a full antibody characterization report linked below. Future studies leveraging these resources may shed light onto the molecular mechanism associated with NDUFS2 linkage with AD risk.NDUFS2在线粒体代谢中的分子功能体现为其参与线粒体内膜呼吸链中的复合物I（complex I）。复合物I的功能对线粒体ATP生成至关重要，同时也参与活性氧（reactive oxygen species）的产生。作为复合物I的核心组成成分，NDUFS2涉及两种作用机制相反的假说，二者均有可能推动阿尔茨海默病（Alzheimer's disease，AD）的病理进程：阿尔茨海默病代谢减退假说（AD Hypometabolism Hypothesis）与阿尔茨海默病氧化应激假说（AD Oxidative Stress Hypothesis）。这两种假说分别隶属于两个已明确界定的生物学领域——线粒体代谢与氧化应激。因此，通过下调NDUFS2的表达以降低复合物I的完整性，既可能促进阿尔茨海默病的病理进程，也可能抑制其进展。本项目的核心目标是通过构建一套基础TEP资源套件（包含下文链接的完整抗体鉴定报告），生成可用于更高效研究NDUFS2在AD发病机制中作用的研究资源。未来利用这些资源开展的研究，有望阐明NDUFS2与AD患病风险相关的分子机制。
