“Magnesium is required by enzymes involved in DNA replication and repair, so chronic inadequacy could allow cellular damage to accumulate over time. Dr. Patrick also discusses matrix metalloproteinases, or MMPs, which help remodel the extracellular matrix.”

“Together, these findings suggest that tanning beds raise melanoma risk in two ways. They increase the total number of mutations inside melanocytes, and they spread this damage across a larger area of the body than natural sunlight typically reaches.”

“It is an essential component of the antioxidant enzyme copper-zinc superoxide dismutase and can induce the expression of other antioxidant enzymes such as metallothioneins. The DNA binding protein p53, which guides a variety of DNA damage response mechanisms, requires zinc for proper function.”

“DNA damage is an aging-associated burden that accumulates, at least partially, due to the failing capacity of our own enzymes to keep up with damage. The secretions of senescent cells can have profound effects on stem cell proliferation and function.”

“This can lead to genomic instability – a wide range of alterations that occur in our DNA and irreversibly change the information carried in our genome. Sirtuins respond quickly to DNA damage within a cell, directing gene expression to promote DNA repair.”

“A study in old mice demonstrated that nicotinamide mononucleotide administration can stimulate repair of DNA damage through PARP1. Specifically, after 22-month-old mice were injected with 500 mg/kg/bw of NMN every day for one week, their hepatic NAD+ concentration and PARP1 activity were increased.”

“For example, correcting vitamin D and magnesium deficiencies can reverse epigenetic aging and protect against DNA damage. Diet should be the primary source of most of our nutrients, but it can be hard to obtain optimal nutrition through whole-food sources.”

“In this Aliquot, I break down what the research tells us about glyphosate exposure in farming communities versus the general population, explore how it may lead to DNA damage, and share practical strategies for reducing exposure—starting with your grocery list.”

“NAD+ facilitates DNA repair Metabolism and day-to-day living can damage DNA, however, necessitating the activation of in-house repair mechanisms. The PARP enzymes, in particular, detect DNA damage and initiate repair responses by recruiting other DNA-repair enzymes.”

“Sulforaphane activates NRF2-regulated cellular defense pathways. In a randomized crossover trial of 60 adults, eating 85 grams of raw watercress daily for eight weeks reduced basal lymphocyte DNA damage by 17% and oxidative purine DNA damage by 23.9%.”
