Durante décadas, la medicina oncológica ha buscado una forma de destruir el cáncer sin arrasar lo sano. Un equipo de investigadores de UC Berkeley, UC San Francisco y los Institutos Gladstone ha publicado en Nature un estudio que acerca esa aspiración a la realidad: mediante una variante de CRISPR llamada Cas12a2, lograron identificar y eliminar selectivamente células con mutaciones cancerosas específicas, dejando intacto el tejido circundante. El hallazgo cobra especial peso en cánceres como el de ovario, páncreas y pulmón, donde la mutación de la proteína supresora p53 —presente en casi la m

Patients with previously incurable cancers gain access to more effective treatments with fewer side effects than chemotherapy. Reduced treatment toxicity could lower healthcare costs and improve quality of life for cancer patients and families.
Regulatory agencies (FDA, EMA) will need to establish expedited approval pathways for CRISPR-based therapies. Patent and intellectual property frameworks require clarification. Healthcare systems must plan for integration and reimbursement models. Ethical guidelines for gene-editing therapies need refinement.
