This research demonstrates that biological sex differences in NAD+ biosynthesis pathways significantly influence susceptibility to ischemia-reperfusion-induced acute kidney injury (AKI). The study identifies sex-dimorphic NAD+ metabolism as a key molecular mechanism underlying sex-biased AKI outcomes. For practitioners, this suggests NAD+-supporting interventions like NMN may have sex-specific efficacy profiles in kidney protection and warrant sex-stratified clinical consideration when addressing AKI prevention.

Sex-dimorphic NAD+ metabolism may explain differential AKI outcomes; NMN support could warrant sex-stratified dosing consideration.
