The homocysteine-inducible, endoplasmic reticulum (ER) stress-inducible, ubiquitin-like domain member 2 (HERPUD1) in cultured HELA cells facilitate cytoprotective effects against oxidative stress by suppressing the inositol 1,4,5-triphosphate receptor and reducing the transfer of calcium ions from the endoplasmic reticulum to mitochondria [41]
The oxidized form, GSSG, can be reduced back to reduced glutathione with the help of glutathione reductase ( GSR gene ) and NADPH
Mechanism of Action Inhibits Nicotinamide N-Methyltransferase (NNMT) Increases intracellular nicotinamide and NAD levels Improves mitochondrial efficiency and energy metabolism Supports lipolysis and fat oxidation Reduces adipocyte (fat cell) growth and proliferation Modulates inflammatory pathways and insulin signaling These effects may lead to enhanced fat metabolism, better blood sugar regulation, improved endurance, and a general increase in metabolic flexibility
Strengthens antioxidant defenses and supports immune function, playing a key role in maintaining overall health
