Durante décadas, la biología celular sostuvo que cada célula custodiaba su propio genoma en soledad. Investigadores de UT Southwestern en Dallas han documentado algo que desafía ese principio fundacional: fragmentos de ADN dañado pueden escapar del núcleo celular, atravesar túneles microscópicos llamados nanotubos y reescribir el genoma de una célula vecina, con cambios que persisten en las células hijas. Este hallazgo, publicado en Cell, no solo amplía lo que sabemos sobre la comunicación entre células, sino que abre preguntas incómodas sobre cómo progresa el cáncer y si los tratamientos actu

Long-term potential for improved cancer treatments and personalized medicine, but near-term impact minimal. May increase healthcare costs if new diagnostic tests or treatments are developed. Could affect cancer patients' treatment outcomes and prognosis understanding.
Likely to trigger regulatory review of cancer therapies and chemotherapy protocols. May prompt new guidelines for genetic testing and tumor monitoring. Could influence bioethics discussions around genetic modification and cellular engineering. May require updated FDA approval pathways for novel cancer treatments targeting intercellular DNA transfer mechanisms.
