We evaluate the mechanism of action of PCMS, a PAMAM-based supramolecule that eradicates cancer cells by reorganizing their internal mechanics rather than their genes. Once internalized, PCMS self-assembles into a perinuclear ring that severs nucleus-cytoskeleton communication. We observed PCMS\u2019s dual-intelligent mechanisms of action: Cytoskeletal rescue, where actin-microtubule filaments move towards the PCMS ring, treating it as a surrogate plasma membrane, attempting to restore vesicular trafficking; Nuclear counter-expansion, where chromatin-lamina condensates undergo stepwise viscoelastic transitions that push the nuclear envelope outward to reestablish membrane contact. These contradictory forces amplify mechanical stress, driving super-critical strain and nuclear lysis without broad transcriptional modulations. By geometry alone, PCMS collapses the actin-microtubule-nucleus continuum and turns the cell\u2019s adaptive machinery into its own executioner. The discovery that life and death decisions can be reprogrammed through spatial conflict establishes a paradigm of mechanical deception, inaugurating a new class of cellular adaptive feedback-targeted mechanotherapeutics that overcome resistance by exploiting the cell\u2019s own morphogenetic logic.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The next-generation anti-cancer therapeutics must disrupt intracellular mechanics, efficiently eradicating cancer cells, rather than simply intoxicating them.
