[Abstract] CD38 is a multifunctional enzyme involved in calcium signaling and Nicotinamide Adenine Dinucleotide (NAD+) metabolism. Through its major activity, the hydrolysis of NAD+, CD38 helps maintain the appropriate levels of this molecule for all NAD+-dependent metabolic processes to occur. Due to current advances and studies relating NAD+ decline and the development of multiple age-related conditions and diseases, CD38 gained importance in both basic science and clinical settings. The discovery and development of strategies to modulate its function and, possibly, treat diseases and improve health span put CD38 under the spotlights. Therefore, a consistent and reliable method to measure its activity and explore its use in medicine is required. We ...
[摘要] CD38是参与钙信号传导和烟酰胺腺嘌呤二核苷酸（NAD + ）代谢的多功能酶。通过其主要活性，NAD + 的水解，CD38有助于维持该分子的适当水平，从而发生所有NAD + 依赖性代谢过程。由于目前有关NAD + 下降和多种年龄相关疾病和疾病发展的研究和进展，CD38在基础科学和临床环境中都具有重要意义。调整其功能，可能治疗疾病和改善健康状况的战略的发现和发展使CD38成为焦点。因此，需要一种一致且可靠的方法来测量其活性并探索其在医学中的用途。我们在这里描述了我们的小组如何测量CD38的水解酶和环化酶活性的方法，利用基于荧光的酶测定法在平板阅读器中使用1，N 6 -Ethenonicotinamide Adenine Dinucleotide（ε-NAD）进行）和烟酰胺鸟嘌呤二核苷酸（NGD）分别作为底物。
【背景】目前关于代谢功能障碍和虚弱的年龄相关发展的研究每天都有更多的证据。众所周知，随着老化的进行，NAD + 水平在预期过程中降低。最近的研究表明，烟酰胺腺嘌呤二核苷酸（NAD + ）的减少与年龄相关的代谢下降有关（Massudi et al。，2012）。增加NAD + 水平体内，导致延长寿命和健康跨度相关因素的活化，并改善衰老的几个生理和代谢参数（Camacho-Pereira ...
