    Consumers beware: direct to consumer genetic testing found to have 40% false positive rates with misclassification of variants. This also includes the interpretative reports that often accompany the direct to consumer genetic test companies or included from 3rd parties. This could have huge implications in the use of Epigenetics, pharmacogenetics, and Cancer genetics.  These genetic testing needs medical interpretation not algorithms.

  • MeB acts as an electron bridge between a donor (FADH2, FMNH, NADH) and an acceptor (complex IV of ETC or oxygen itself)
  • As a coenzyme of pyruvate dehydrogenase (PDH), alpha-lipoic acid (ALA) initiates the formation of acetyl-CoA to feed the TCA cycle

  • Methylene Blue plays a similar role after the TCA cycle, by carrying electrons to complex IV of the electron transport chain
  • Drugs such as lipoic acid and MeB, which target the metabolism, decrease the redox shift by increasing catabolism

  • short-term HFO introduces DNA methylation changes on a genome-wide scale in human skeletal muscle
  • These changes were only partly reversed after 6–8 weeks
  • The induction of DNA methylation changes after 5 days of HFO supports the growing awareness of DNA methylation as a dynamic signal that is possibly relevant to short-term day-to-day metabolic adaptations, including acute exercise
  • ...4 more annotations...
  • Diverging DNA methylation levels between elderly, but not young, genetically identical twins indicate that environmental exposures throughout life may permanently influence DNA methylation, suggesting some preservation of de novo DNA methylation in adults
  • our finding of a slow reversibility rate indicates the demethylation process may be somewhat impeded compared with the induction of methylation changes by diet, which could have implications for the preservation or build-up of CpG methylation over time
  • A slow reversibility of DNA methylation induced by carcinogenic agents has likewise been observed due to ingestion of high-fat diets in rodents
  • the relationship between DNA methylation and gene expression is not always straightforward
  • Nathan Goodyear on 03 Oct 17
     
    Study finds variability of methylation and some genetic expression alteration with high fat diet.  Restated, what you eat interacts with your DNA to alter genetic expression.  This has implications on initiation of therapy as well as response to therapy.

    How you respond to stress is a reflection of your genetics and environment.  The bodies ability to express genes, such as the glial cell-derived neurotrophic factor, impacts an individual's expression in the face of stress.  You have a genetic predisposition, but with poor methylation you end up with more depression in the presence of stress
