“Maternal diabetes increased the abundance of biomarkers of cellular senescence and DNA damage in the lining of the brain in offspring. Pregnant diabetic mice that were exposed to rapamycin had offspring with lower levels of senescence biomarkers and fewer neural tube defects compared to placebo.”

“It plays roles in immune function, protein synthesis, wound healing, DNA synthesis, and cell division and modulates the activity of more than 300 enzymes and 2,000 transcription factors. Learn more about zinc in our comprehensive overview article.”

“New Scientist article. 02:06:10 - Some people, like Tom Cruise and Keanu Reeves, seem to defy aging. 02:08:15 - One 12-ounce can of sugar-sweetened soft drink per day shortened telomere length, corresponding to 4.6 years of biological aging.”

“In addition to the infection prevention benefits to the host, L. reuteri produces vitamin B12 (also called cobalamin), an essential nutrient that acts as a cofactor in the synthesis of DNA and in the metabolism of dietary fat and protein.”

“it’s also an important source of DNA damage, which is a fundamental mechanism of aging itself. This is one reason why it shouldn’t surprise us that lower inflammation is also associated with longer lifespan, prolonged physical function and also cognitive abilities in old age.”

“Furthermore, mRNA is a labile molecule that does not enter the nucleus, and thus safety concerns are low. Other vaccines include the AstraZeneca vaccine, which delivers a small piece of DNA encoding the spike protein via an adenoviral vector.”

“A 40-day cluster-randomized crossover trial involving 149 schoolchildren found lower pyrethroid and neonicotinoid pesticide exposure during the organic-diet period, along with reductions over time in biomarkers of oxidative stress and inflammation, including markers of oxidative DNA damage and lipid peroxidation.”

“They repeated their experiment in monkeys, worms, and yeast and observed similar effects. They also found that taurine reduced several hallmarks of aging in all the species studied, including cellular senescence, mitochondrial dysfunction, DNA damage, and inflammation.”

“Some evidence suggests that folate, a B vitamin, might help protect against lead's neurotoxic effects. A recent study found that higher folate levels during pregnancy may help reduce the risk of autism-like behaviors in children exposed to lead before birth.”

“Body fat also alters hormone levels, which may increase the risk of developing hormone-sensitive cancers, such as breast cancer. In addition, body fat secretes a wide array of pro-inflammatory substances that damage DNA and inhibit apoptosis.”
