  • Small genetic messages from young ovarian support cells may suppress mobile genetic elements

    Where this hypothesis actsRecipient tissues exposed to signals from young ovarian somatic cells

    What is proposedSuppress active retroelements through sequence-specific RNA restriction

    With whatRNA interference or antisense

    HowSmall RNAs exported by young ovarian somatic cells would reach recipient Argonaute complexes and act through matching target sequences

    Possible resultPossible reduction in innate immune activation and injury, with a survival benefit

  • Mobile genetic element cutting may restart cellular senescence after senescent-cell removal

    Where this hypothesis actsTracked, previously nonsenescent cells after confirmed removal of the initial senescent population

    What is proposedGenetically suppress LINE-1 activity

    With whatControlled genetic model

    HowGenetic suppression followed by restoration with endonuclease-active or endonuclease-disabled ORF2 to test dependence on endonuclease activity

    Possible resultPossible prevention of recurrent senescence and intertissue damage
