NAD⁺ Acts as a Protective Factor in Cellular Stress Response to DNA Alkylating Agents.

ABSTRACT: Sulfur mustard (SM) and its derivatives are potent genotoxic agents, which have been shown to trigger the activation of poly (ADP-ribose) polymerases (PARPs) and the depletion of their substrate, nicotinamide adenine dinucleotide (NAD⁺). NAD⁺ is an essential molecule involved in numerous cellular pathways, including genome integrity and DNA repair, and thus, NAD⁺ supplementation might be beneficial for mitigating mustard-induced (geno)toxicity. In this study, the role of NAD⁺ depletion and elevation in the genotoxic stress response to SM derivatives, i.e., the monofunctional agent 2-chloroethyl-ethyl sulfide (CEES) and the crosslinking agent mechlorethamine (HN2), was investigated with the use of NAD⁺ booster nicotinamide riboside (NR)
