Related Episodes for How changes in cellular identity and stem cell differentiation affect epigenetic age

“Dr. van Loon sees useful research questions in skin, joints, and recovery after orthopedic surgery, but he keeps those possibilities separate from established muscle-building effects.”

“01:52:55 - Environmental enrichment creates epigenetic changes that benefit learning and memory in rodents and these benefits transfer to offspring. Study. 02:05:00 - NASA study showed that gravity influenced expression of genes involved in metastasis.”

“00:34:40 - Repeated traumatic brain injury has cumulative neuroinflammatory effects in the brain over years, including amyloid-beta plaque and tau tangle formation. Study. 00:44:00 - A variant of the APOE gene increases risk of developing Alzheimer’s disease as much as 15-fold.”

“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.”

“A recent study identified the branched-chain amino acid leucine as the primary amino acid sensor for mTOR. Interestingly, branched-chain amino acids have been favored by bodybuilders because of their ability to enhance muscle growth.”

“Rumination, the practice of dwelling on external stressors to excess, can set in motion a cascade of hormonal and physiological responses that harm mental and physical health. Meditation has been shown to reduce rumination and its negative effects, however, and influences the gene expression of as many as 500 genes, many of which are in the brain.”

“Using a Mendelian randomization analysis, scientists determined that people carrying genetic variants associated with low vitamin D levels have higher mortality from respiratory tract infections and higher all-cause mortality.”

“Gene polymorphisms, small changes in an organism's DNA sequence, can affect the absorption and metabolism of nutrients, including vitamins and minerals. A polymorphism in the MTHFR gene that decreases enzyme activity leads to inefficient folate metabolism.”

“More than a century of research has demonstrated that nicotinamide adenine dinucleotide (NAD+) is an indispensable mediator of vital metabolic and physiological processes, including energy production, DNA synthesis and repair, and regulation of gene expression – across multiple species.”

“A few examples of genes with common polymorphism discussed are MTHFR and folate, NBPF3 and vitamin B6, FUT2 and vitamin B12, BCMO1 and beta-carotene, FADS2 and omega-3 fatty acids, CYP2R1 and vitamin D, PEMT and choline as well as APOE4 and FOXO3.”
