In mouse tumor models, activating Cas12a2 by a target transcript enables RNA-triggered chromatin shredding that selectively eliminates cells with mutations in TP53, MYC, and other hard-to-drug cancer genes.
- Why it matters: Conventional drugs often fail against cancers driven by resistant mutations, so new strategies are needed that can target these hard-to-drug genetic drivers.
- What they did: Two studies tested RNA-triggered chromatin shredding in mouse models, using Cas12a2 activated by a tumor-associated transcript to target mutant cancer genes.
- The result: The approach is linked to selective tumor-cell elimination in mice, suggesting a potential new therapeutic route for mutation-driven cancers that resist conventional treatments.
