2020年3月3日,美国国立卫生研究院(NIH)环境健康科学研究所李小玲(Xiaoling Li)研究组,联合该所质谱平台主任Jason Williams以及杜克大学Jason Locasale教授等在Cell Metabolism杂志上发表题为Bacteria boost mammalian host NAD metabolism by engaging ...
而烟酰胺可以通过一个叫做NAMPT的酶转化回NAD+。这条通路就是NAD+的内循环,也叫做NAD+打捞通路(salvage pathway),简单的可以理解为,人体自身合成NAD+的路线。 为什么说NAD+的内循环比服用NAD+的前体更重要?是因为服用NAD+前体只能在短时间提供一次性的NAD+水平的提升,在NAMPT活性未提升的情况下,之后的内循环无法...

However, the relative contribution of each pathway to NAD+ biosynthesis under both normal and CR conditions is not known. Here, we have performed lifespan, NAD+ and NADH (the reduced form of NAD+) analyses on BY4742 wild-type, NAD+ salvage pathway knockout ( npt1 ) and NAD+ de novo ...
人工设计的C3N途径是利用合成生物学手段探索NAD+从头合成问题的一个解答，不仅为研究NAD+这类重要分子合成的基础科学问题提供了新思路，还将有力促进涉及NAD(H)的应用研究。该研究以“Construction of an alternative NAD+de novo biosynthesis pathway”为题，2021年3月2日在线发表于Advanced Science。中国科学院微生物...
