Project Summary Nicotinamide adenine dinucleotide (NAD) is a redox cofactor required by enzymes essential to energy production and numerous other cellular processes. NAD also serves as a co-substrate for several classes of signaling enzymes, each of which cleaves the molecule to release nicotinamide. Cellular NAD is derived from dietary tryptophan (de novo synthesis), nicotinic acid (the Preiss-Handler pathway) or recycled from nicotinamide via the NAD salvage pathway. NAD deficiency can be triggered by a variety of cellular stresses, including DNA damage, and is thought to contribute to pathophysiology in a number of metabolic, neurological, and muscular diseases: conversely, increasing NAD+ has been suggested as a promising therapeutic strategy. Here, researchers will collaborate to develop and utilize a cellular High Throughput Screening (HTS) assay to discover and validate small molecules that increase intracellular NAD+ levels. These studies should identify novel small molecules with great therapeutic potential for a myriad of neurological and muscular including brain ischemia, Wallerian nerve degeneration, misfolded prion protein toxicity, Alzheimer's disease (AD), mitochondrial myopathy (MM), age related sarcopenia and Duchenne's muscular dystrophy(DMD).

项目摘要 烟酰胺腺嘌呤二核苷酸（NAD）是能量必需酶所需的氧化还原辅因子 生产和许多其他细胞过程。NAD还充当几种类别的共底物 每一种酶都能切割分子释放烟酰胺。细胞NAD衍生 从饮食中的色氨酸（从头合成），烟酸（Preiss-peptide途径）或从 烟酰胺通过NAD补救途径。多种细胞可以引发NAD缺乏症 压力，包括DNA损伤，并被认为有助于在一些代谢， 神经和肌肉疾病：相反，增加NAD+被认为是一种有希望的治疗方法。 治疗策略在这里，研究人员将合作开发和利用一种细胞高通量 筛选（HTS）试验，以发现和验证增加细胞内NAD+水平的小分子。 这些研究应该确定新的小分子，具有巨大的治疗潜力，为无数的 神经和肌肉，包括脑缺血、沃勒神经变性、错误折叠朊病毒 蛋白质毒性、阿尔茨海默病（AD）、线粒体肌病（MM）、年龄相关的肌肉减少症和 杜氏肌营养不良症（DMD）。
