    High Cortisol In 5-year-old Children Causes Loss Of DNA Methylation In SINE Retrotransposons: A

    Whats interesting here is it's showing cortisol demethylating dna? Lowering cortisol in certain circumstance might not be ideal? High cortisol in 5-year-old children causes loss of DNA methylation in SINE retrotransposons: a possible role for ZNF263 in stress-related diseases "Childhood stress...

    No Need For Mutations, Mitochondrial Stress Alone Can Trigger Cancer

    As Ray said, the official story on cancer and many other conditions thought to be genetic is slowly changing. The powers that be won't admit overnight that genetics has little (if anything) to do with cancer, but the evidence for metabolic dysfunction as a cause of cancer is slowly building up...

    Coffee consumption rapidly reduces background DNA strand breaks in healthy humans

    www.ncbi.nlm.nih.gov/pubmed/16870158 Abstract The activity of the nuclear enzyme poly(ADP-ribose)polymerase-1 (E.C.2.4.2.30), which is highly activated by DNA strand breaks, is associated with the pathophysiology of both acute as well as chronic inflammatory diseases. PARP-1 overactivation...

    Coffee Consumption Protects DNA Integrity

    The study looked at coffee (750ml daily, which is about 3 cups), not caffeine, even though I suspect the benefits are mostly due to caffeine and the iron-reducing effects of chlorogenic acid. http://www.ncbi.nlm.nih.gov/pubmed/24740588

    Mitochondrial Dna Transfer

    http://www.malaghan.org.nz/news-and-eve ... -observed/ It looks like scientists have observed mitochondrial DNA (mDNA) transfers from healthy to tumour cells in animals for the first time. I'm not sure if the spread of the tumour means that the mDNA spread as well to healthy cells, or if the...

    DNA Methylation, Aging, And Cancer

    Hi all, Ray Peat has talked about this in some of his articles, and mentioned some specific techniques one can use to combat aging. This article talks about the relationship between the levels of methylation, aging, and cancer. As you suspect, with time methylation increases the risk of...
