Mechanisms of DNA Repair
DNA repair mechanisms ensure genomic stability by correcting damage and preserving cellular health. These repair processes involve several key pathways to rectify damage efficiently.
Key DNA Repair Pathways
Cells deploy multiple repair strategies, each addressing specific types of DNA lesions. Base excision repair (BER) fixes small base modifications, while nucleotide excision repair (NER) handles bulky helix-distorting lesions. Double-strand breaks, the most severe kind, are resolved through homologous recombination (HR) and non-homologous end joining (NHEJ).
NAD+ plays a vital role in these pathways. It serves as a substrate for enzymes like PARPs, crucial in recognizing and signaling DNA damage. By fueling these repair enzymes, NAD+ maintains the integrity of cellular genetic material. Compounds like Resveratrol and NMN support NAD+ synthesis, further enhancing repair efficiency.
Importance for Cell Health
Efficient DNA repair is fundamental for cell vitality, preventing mutations and ensuring normal cell function. This process reduces the risk of diseases associated with genomic instability, such as cancer.
