United KingdomResearchers led by Dr. Wang Yu from the Chinese Academy of Sciences have developed PRINCE and Little Prince, two small-molecule-controlled genome editing systems that enable CRISPR activity to be turned on and off using drug inducers. These systems offer improved control over gene editing compared to current methods, which rely on passive degradation. PRINCE uses dual regulatory layers—controlling both the nuclease and guide RNA—with results showing minimal off-target effects even after long-term cell culture. A smaller version called Little Prince was tested in mice, demonstrating effective in situ genome editing for treating conditions like hypercholesterolemia. The technology aims to provide safer, more precise gene-editing tools for clinical applications.
