La técnica, conocida como interferencia del ARN, destruye las células tumorales anulando genes del virus implicado en la enfermedad.
El cáncer de cuello uterino está asociado al virus del papiloma humano (VPH), que ataca a las proteínas p53 y RB del organismo. La primera se encarga de destruir las células dañadas que pueden volverse cancerosas, mientras que la segunda está implicada en la división celular. Los científicos han constatado que cuando anulan dos genes del virus, las células mueren y el resto no resulta dañado.
Al contrario de la quimioterapia, la interferencia del ARN respeta el sistema inmunológico y sólo afecta a las células cancerosas, afirman.
La investigación se publica en "Oncogene".
