“The human genome does not contain the genes necessary to produce vitamin B12, so it must be acquired via the diet. Cobalamin is also an essential nutrient for bacterial metabolism; however, most bacteria lack the genes to produce and must also obtain it from the environment.”

“Multiplex editing allows geneticists to make multiple genome alterations at once. Using this amazing technology, humanized organs from large mammals like pigs will enable organ transplantation on demand instead of patients waiting for years for a donor.”

“Dr. Patrick also describes a trial in vitamin-D-deficient, overweight African-American adults in which 4,000 IU per day reduced an epigenetic-age measure by almost two years. Epigenetic age is a surrogate biomarker, not proof that vitamin D slowed clinical aging, prevented disease, or extended life.”

“Even if mRNA could enter the nucleus, two other enzymes are missing to transform RNA into DNA and insert it into the human genome. Thus, the series of steps that would result in mRNA incorporating into nuclear DNA is biologically implausible.”

“In order to produce new mitochondria each of your existing mitochondria have to synthesize their genome anew (yes, mitochondria have their own genome) and this depends on enzymes that require magnesium as a cofactor to do just that (1,2).”

“Genome-wide mapping has identified thousands of vitamin D receptor binding sites and hundreds of genes whose expression changes after calcitriol exposure. Dr. Patrick also reviews a 16-week randomized trial in adults with low vitamin D status.”

“A key player in this pathway is the gut microbiome, the collection of genomes of the microorganisms that exist in the gastrointestinal tract. Sleep deprivation alters the overall gut microbial make-up, which can promote dysregulation of the microbiome and in turn, altered sleep.”

“The microbiome is the combined genomes of the trillions of microbes that live on or in the body. It can be influenced by medications, such as antibiotics, and the food we eat. Fiber, of various types, serves as a rich nutrient source for the bacteria that live in our guts.”

“"Anything that persistent damage to the genome will drive cells into senescence. It makes sense because that puts you at risk for mutations. Mutation puts you at risk for cancer, so the cells want to shut that damaged cell down."”

“- Dr. Steve Horvath https://www.foundmyfitness.com/episodes/steve-horvath'] In recent years scientists have identified ways to measure aging based on the methylation pattern of an organism's genome – what scientists refer as DNAm (where the "m" represents methylation).”
