This study uses clinical samples, molecular biology techniques, pharmacological interventions, and genetic approaches to investigate the significance of NAD+ levels in cross-species models of PD. These results reveal that treatment of rotenone-incubated cells with NAD+ boosters (such as NMN, siCD38, and NAT) increases UPR<sup>mt</sup>/mitophagy-related MQC, reduces pro-inflammatory cytokine expression, inhibits apoptosis, and strengthen redox reactions.

Notably, bulk omics signatures and metabolomic profiling analyses of the striatum reveal NMN-induced transcriptional changes in genes and proteins involved in mitochondrial homeostasis.
