Understanding DNA Repair
DNA repair is a vital process that maintains the integrity of our genetic material. Our cells constantly face damage from various sources like UV rays, chemicals, and metabolic byproducts. To combat this, they rely on intricate repair mechanisms, which include direct reversal, excision repair, and double-strand break repair. These pathways work together to fix different types of DNA damage.
NAD+ plays a crucial role in these repair processes. It's a key cofactor in poly (ADP-ribose) polymerase (PARP) enzymes involved in single-strand break repair. When NAD+ levels decline with age, the efficiency of DNA repair mechanisms decreases, leading to accumulated DNA damage. By boosting NAD+ levels through NAD+ precursors like NMN, we can potentially enhance the DNA repair capacity of our cells, promoting cellular health and longevity.
Research has shown that other molecules like Resveratrol, Spermidine, and Fisetin can support DNA repair processes.
