Abstract
Nicotinamide riboside (NR) is a form of vitamin B <sub>3</sub> and is one of the most studied compounds for the restoration of cellular NAD <sup>+</sup> levels demonstrating clinical potential in many metabolic and age-related disorders. Despite its wide commercial availability as a powerful nutraceutical, our understanding of NR uptake by different cells and tissues is greatly limited by the lack of noninvasive in vivo imaging tools limiting its clinical translation. Here, we report the development and validation of a bioluminescent NR uptake probe (BiNR) for non-invasive longitudinal imaging of NR uptake both in vitro and in vivo. In addition, we optimized an assay that allows monitoring of NR flux without the need to transfect cells with the luciferase gene, enabling the use of the BiNR probe in clinical samples, as demonstrated with human T cells. Lastly, we used BiNR to investigate the role of NR uptake in cancer prevalence and metastases formation in triple negative breast cancer (TNBC) animal model. Our results demonstrate that NR supplementation results in a significant increase in cancer prevalence and metastases of TNBC to the brain. These results outline the important role of powerful nutraceuticals like NR in cancer metabolism and the need to personalize their use in certain patient populations.
