“Yellow and orange carotenoids absorb light in the high-frequency blue/violet range, making them particularly well-suited for protecting the body from ultraviolet radiation, which creates hydroxyl and oxygen radicals that can damage DNA.”

“Telomeres are tiny caps on the end of our chromosomes that protect DNA from damage. Telomeres get shorter each year until they reach a critical length which causes the cell to either die or become senescent (metabolically inactive). When this occurs in stem cells, it leads to tissue aging.”

“Damage-associated molecular patterns (DAMPs) such as high-mobility group protein (HMG)-1, which organizes chromatin and controls DNA transcription, also bind to immune receptors that stimulate inflammation.”

“They play important roles in human lifespan and healthy aging. FOXO3s regulate a vast number of genes that combat elements of cellular aging, such as damage to DNA, proteins, and lipids, and loss of stem cell function.”

“One enzyme, copper-zinc superoxide dismutase, neutralizes hydrogen peroxide radicals by accepting an electron at its copper site. By absorbing reactive oxygen species, antioxidant compounds prevent damage to structures such as lipid membranes, enzymes, and DNA.”

“Researchers in the field of aging have posited several theories to explain how and why the body ages. One of these theories, the somatic mutation theory of aging, is based on the idea that DNA damage accumulates over time – the result of day-to-day living and oxidative stress.”

“Building stuff (anabolism). Repairing stuff. NAD's role in DNA repair Brenner emphasizes that "repair" is a huge category and includes both rebuilding and damage response signaling.”

“Hyperthermia, a state of elevated core body temperature, stresses the body, activating molecular mechanisms that mitigate protein damage and aggregation and promote endogenous antioxidant, repair, and degradation processes.”

“The results of the study indicate that diets rich in nicotinamide riboside, a derivative of vitamin B3, protect these mice from developing HCC in its most initial stage, when genotoxic stress is damaging cellular DNA.”

“The bacteria penetrate through the gut barrier and release compounds that damage DNA and inflame colon cells. This can both induce colon cancer and/or allow precancerous cells to grow into cancer. The strains of bacteria are Bacteroides fragilis and a strain of E.”
