Inhibition1

  • Estrogen re-exposure may kill breast cell lineages by rupturing deprivation-altered lysosomes

    Where this hypothesis actsBreast lineages undergoing lysosomal leakage during estrogen re-exposure after prolonged deprivation

    What is proposedSuppress the responsible cathepsins to test their requirement for lineage elimination

    With whatNot stated in the record

    HowUse independently validated suppression with orthogonal interventions, checking intracellular steroid exposure after each intervention

    Possible resultExpected restoration of post-washout clonogenic survival if cathepsins are required for lineage elimination
