CRISPR Technology Advances with New Method to Target and Destroy Cancer Cells
Researchers have developed a new CRISPR system, Cas12a2, which can selectively target and destroy cancer cells while leaving healthy cells unharmed. This system acts as a self-destruct mechanism for diseased cells, differing from the traditional Cas9 system known for its precise DNA editing capabilities. The study, published in Nature, highlights Cas12a2's ability to identify and eliminate cells with specific RNA sequences, such as those carrying the cancer-driving KRAS mutation. In experiments with mice, a single treatment using this method reduced tumor volume by approximately 50%. The research suggests a shift in cancer treatment strategies, focusing on the selective elimination of harmful cells rather than broad-spectrum therapies.
