Some cancer cells survive chemo not by sleeping, but by constantly dying and dividing in a high-stakes balancing act.

The Takeaway
This 'persister' state was thought to be a uniform, dormant shield, but it is actually a chaotic, active population. Because they are constantly changing, they develop new vulnerabilities like ferroptosis that we can exploit to kill them off permanently.
From the abstract
Drug-tolerant persisters (DTPs) represent a major obstacle to durable responses in targeted cancer therapy. DTPs are commonly described as distinct single-cell states that survive drug treatment via reversible, non-genetic mechanisms and drive tumor recurrence. Recent work demonstrates that multiple DTPs can coexist, reflecting diversity in lineage, signaling programs, or stress responses. However, each DTP is still generally viewed as a uniform cellular phenotype. Building on our prior work des
