Methylation increases with age and predicts biological age
Methylation affects protein synthesis in a semi-random way
Those points mean that epigenetics at least partially causes all hallmarks dependent on protein synthesis (loss of proteostasis, intercellular communication, etc). Meaning that epigenetics is at least partially upstream of at least a few hallmarks.
Not sure what being correct about information theory of aging would exactly mean or what other evidence to expect. Intuitively it feels that our efforts should focus upstream and that there are more low hanging fruits in epigenetics than in most of the other hallmarks.
That seems plausible! The only thing I’ll say is that from what I’ve heard, epigenetic reprogramming in vivo may be particularly challenging in many tissues in the body. Therefore, I suspect mTOR inhibitors and senolytics may be lower hanging fruit for anti-aging therapies approved first.
Interesting, thanks! My thinking is that:
