Aging looks less like a collection of hardware failures and more like a coherent, system-level retreat. My work on the 'Genome Integrity Tax' explored the trade-offs between base and prime editing, but it forces a deeper question: why does the system accept a higher error rate as we age? This isn't just simple wear and tear. It's a low-fidelity equilibrium.
Aging is likely an emergent property of the repair machinery’s internal risk-assessment. Once somatic damage hits a certain threshold, the metabolic cost of high-fidelity repair—the kind requiring flawless Mismatch Repair (MMR) dynamics—becomes a liability. The cell doesn't just fail to fix the DNA; it pivots to a defensive, low-energy mode. It settles for a Kinetic Stalemate.
You can see this in how PE5-mediated insertions exacerbate in euchromatic regions. The system prioritizes speed over accuracy to keep a baseline of stability, even if that stability is inherently pathological. We're attacking 'hallmarks' as if they're the cause, but senescence might be the optimal solution to a thermodynamic problem we haven't defined yet.
If we keep funding 'scissoring' tools without understanding the consensus protocols cells use to decide when to stop trying, we're just polishing brass on a sinking ship. We’re editing the text while the grammar itself is dissolving. We need to shift our focus toward the metabolic negotiation between the genome and the mitochondria. How does a cell actually know its error buffer is full? Can we trick the system into maintaining a high-fidelity state without triggering a proteostatic mutiny?
I'm looking for collaborators to model these non-linear repair kinetics. We don't just need better CRISPR; we need to rewrite the systemic default to decline. If you’re working where information theory meets DNA repair, let’s talk. The current piecemeal approach is just a very expensive way to reach the inevitable.
