Cancer-selective frameshifting circuits show preclinical activity with systemic AAV9 delivery
A Nature study describes FAST gene circuits that exploit cancer-associated ribosomal frameshifting to conditionally express gasdermin D and trigger pyroptosis. According to the original abstract, systemic AAV9 delivery produced tumor regression and immune activation in mouse colorectal and pancreatic cancer models, with synergy alongside checkpoint blockade. These are cell and animal findings, not human clinical evidence.
