Activation1

  • Altered cells may suppress normal repair through an enzyme above a local abundance threshold

    Where this hypothesis actsNormal cells exposed to the mimetic alongside altered cells

    What is proposedStimulate autophagy while limiting NOTUM-mediated competition

    With whatSmall molecule

    HowUse an autophagy mimetic together with time-limited NOTUM suppression

    Possible resultPossible retention of the normal-cell autophagic response without the threshold-dependent clonal advantage

Function preservation1

  • Different protein lifetimes may separate spermidine-driven cell recycling from clonal growth

    Where this hypothesis actsIntestinal organoids after a short spermidine-mimetic pulse and during feeding resumption

    What is proposedSustain elevated autophagic flux through the resumption of feeding

    With whatSmall molecule

    HowApply a short spermidine-mimetic pulse and resume feeding while the TFEB-induced lysosomal machinery remains functional after additional MYC activity subsides

    Possible resultPossible continued recycling of damaged components and functional benefit with less growth of altered cells
