Signal-2-Noise: mTOR, Metabolism and Inflammation are aging's Alarm Bells.

if we silencing the three loudest "alarm bells" of aging at the same time: Hyperactive Growth Signaling (mTORC1), Metabolic Exhaustion (Peroxisomes), and Sterile Inflammation (Cytosolic DNA) it wont actually repair us repair, it will break the immune system - we need to be episodic in our approach...

Why? Previous attempts (like the ITP’s NEBI study) likely failed because they blocked the signal chronically, freezing the system.

Lets do the opposite:

Pulsed NEBI: tap the brakes on mTOR just once a week to induce autophagy without stalling growth—turning a "stop" signal into a "reset" signal.
Alpha-Ketobutyrate: fuel the peroxisomes (the cell's other incinerator), forcing them to burn the toxic lipids that mitochondria can’t handle.
DNase Exosomes: scrub the blood of cell-free DNA—the "ghosts" of dead cells that trick the body into thinking it’s under viral attack (cGAS-STING pathway).

the test: lets take 18-month-old mice and put them on this "Noise-Cancelling" regimen. if we see inflammation (IL-6, SASP) drop by say 40% and lifespan extend by say 25%, we prove that aging bout the body screaming at itself (noise) rather than the actual damage being created. By toning down that noise we will let the repair systems go back to work...

thank you for your input james!

The episodic approach aligns with what we see in long-lived species. Bats and hibernating mammals naturally cycle through metabolic states—torpor suppresses mTOR, then arousal restores it. This pulsing may be part of their longevity mechanism.

Your framework suggests aging is not cumulative damage but chronic signaling dysfunction. If so, long-lived species may have evolved better noise-filtering systems, not just better repair.

Question: would the pulsed NEBI schedule mimic the natural metabolic cycling seen in torpor-capable mammals? If so, this would be an evolved strategy, not just an engineering workaround.

Exactly!

...hibernating species undergo massive, cyclical suppression of mTOR and metabolic rate (quite phase), followed by rapid re-warming and growth (loud phase). ... it is a maintenance cycle.

The quiet phase: autophagy clears the accumulated protein aggregates (tau, amyloid) that would otherwise kill a neuron.. thats why i said we should pulse

The loud phase: mTOR reactivates to rebuild synaptic connections and muscle, which prevents the atrophy seen in chronic suppression...

Pulsed > chronic is now well-established — the mTORC2 preservation is the key mechanistic insight. The 42% life expectancy gain in transient dosing (Selman et al) is striking. Worth noting the female-specific cancer signal though — would need monitoring in any human trial. Alpha-ketobutyrate for peroxisome support is creative but less validated than the rapamycin piece.

tell me how the cancer signal arose, and why it would be specific to women. - is there a quick way we can test this in vitro?
