PMC NAD+-Dependent Enzymes: PARP & DNA Repair NAD+ serves as a substrate for poly(ADP-ribose) polymerase (PARP), sirtuin, and NAD glycohydrolase enzymes, regulating DNA repair, gene expression, energy metabolism, and cellular stress responses
Glycolytic intermediates are shown to increase intracellular ATP levels, promoting anaerobic glycolysis by enhancing the availability of anaerobic substrates [112]
This helps protect cells from oxidative stress, supports detoxification pathways, promotes immune resilience, and contributes to overall cellular health
Accompanied by the release of cytochrome c into the cytoplasm, apoptotic protease activator-1 (Apaf-1) can respond to the release of cytochrome c and bind to it to form multimers, as well as contributing to the binding of caspase-9 to form apoptotic vesicles and induce apoptosis
In addition to important role in the folate cycle that is involved in the reduction of BH 2 to BH 4 , it is an important component in homocysteine metabolism via the methionine cycle (Figure 8), and is critical for neural tube development
