How DNA Methylation Builds Epigenetic Clocks

Send us Fan MailWe follow the trail from DNA methylation to epigenetic clocks that can read biological age like a personalized receipt of your life. Then we hit the hard limits of today’s tests, especially the gap between predicting lifespan and predicting whether your brain stays sharp.• DNA methylation as gene control through steric hindrance and chromatin tightening • Epigenetic clocks built from predictable CpG changes over time • Why first-generation clocks track birthdays more than health • PhenoAge and GrimAge as decay predictors tied to inflammation and smoking damage • French centenarian data showing biological ages decades younger • Epigenetic drift versus clock-like methylation changes and what superagers reveal • ELOVL2 and mouse evidence that some aging is reversible gene silencing • WIMS findings showing blood clocks predict survival not dementia risk • APOE E2 E3 E4 risk differences and epigenetic “volume dial” control • FOXO3 activation through fasting via IGF-1 and AKT signaling • Metformin and rapamycin as fasting mimetics plus the mouse-to-primate reality check Keep your biological software updated, embrace a little bit of hunger, stay curious, and we'll see you next time.This podcast is created by Ai for educational and entertainment purposes only and does not constitute professional medical or health advice.
