BST1 regulates nicotinamide riboside metabolism via its glycohydrolase and base-exchange activities
19 Nov 2021
Abstract excerpt
Abstract Nicotinamide riboside (NR) is one of the orally bioavailable NAD+ precursors and has been demonstrated to exhibit beneficial effects against aging and aging-associated diseases. However, the metabolic pathway of NR in vivo is not yet fully understood. Here, we demonstrate that orally administered NR increases NAD+ level via two different pathways. In the early phase, NR was directly absorbed and...
