Targeting NAD⁺ metabolism: dual roles in cancer treatment.

ABSTRACT: Nicotinamide adenine dinucleotide (NAD⁺) is indispensable for various oxidation-reduction reactions in mammalian cells, particularly during energy production. Malignant cells increase the expression levels of NAD⁺ biosynthesis enzymes for rapid proliferation and biomass production. Furthermore, mounting proof has indicated that NAD-degrading enzymes (NADases) play a role in creating the immunosuppressive tumor microenvironment (TME). Interestingly, both inhibiting NAD⁺ synthesis and targeting NADase have positive implications for cancer treatment. Here we summarize the detrimental outcomes of increased NAD⁺ production, the functions of NAD⁺ metabolic enzymes in creating an immunosuppressive TME, and discuss the progress and clinical tr
