Investigadores de la Universidad de Queenslad, en Australia, desarrollaron una prueba universal, mediante el uso de nanoparticulas de oro, que puede detectar casi cualquier tipo de c\u00e1ncer en tan solo diez minutos.<\/strong><\/p>\n

Los cient\u00edficos descubrieron que la metilaci\u00f3n hace que el ADN de las c\u00e9lulas\u00a0cancer\u00edgenas\u00a0se pliegue formando nanoestructuras en 3D que tienen una gran afinidad con el oro, lo que no ocurre en las c\u00e9lulas sanas<\/strong>.<\/p>\n

\u201cEsto llev\u00f3 a la creaci\u00f3n de dispositivos de detecci\u00f3n econ\u00f3micos y port\u00e1tiles que podr\u00edan usarse como herramienta de diagn\u00f3stico, posiblemente con un tel\u00e9fono m\u00f3vil\u201d, dijo el profesor Matt Trau<\/strong>, uno de los principales investigadores del proyecto, cit\u00f3 el diario The Sydney Morning Herald.<\/p>\n

A partir de ese hallazgo, los autores del estudio desarrollaron una prueba basada en una soluci\u00f3n que contiene agua y part\u00edculas de oro.<\/strong> Al entrar en contacto con las c\u00e9lulas, si estas son cancer\u00edgenas, se vuelve de color rosa, y si est\u00e1n sanas de color azul.\u00a0Las diminutas mol\u00e9culas que decoran el ADN, llamadas grupos metilo, son alteradas dram\u00e1ticamente por el c\u00e1ncer.<\/strong><\/p>\n

El profesor Trau dijo que el equipo descubri\u00f3 que los grupos intensos de metilo colocados en una soluci\u00f3n hicieron que los fragmentos de ADN del c\u00e1ncer se plegaran en nanoestructuras tridimensionales<\/strong> \u00fanicas que podr\u00edan separarse f\u00e1cilmente peg\u00e1ndose a superficies s\u00f3lidas como el oro.<\/p>\n

\u201cDise\u00f1amos una prueba simple con nanopart\u00edculas de oro que cambian de color instant\u00e1neamente<\/strong> para determinar si las nanoestructuras 3D del ADN del c\u00e1ncer est\u00e1n presentes\u201d, dijo el profesor Trau.<\/p>\n

\"\"<\/a><\/p>\n

La tecnolog\u00eda ha demostrado tener una precisi\u00f3n de hasta el 90 por ciento<\/strong> en pruebas que incluyen 200 muestras de c\u00e1ncer humano y ADN normal.<\/p>\n

Esta prueba funciona separando a los genes que son necesarios, de los que no lo son. Mediante el estudio, los investigadores encontraron los patrones que identifican al\u00a0c\u00e1ncer de mama, pr\u00f3stata y colorrectal, as\u00ed como el\u00a0linfoma.<\/strong><\/p>\n

Se considera que esta nueva t\u00e9cnica sea una herramienta de detecci\u00f3n para informar a los especialistas, cuando un paciente puede tener c\u00e1ncer. Sin embargo despu\u00e9s de esta prueba a\u00fan se requieren\u00a0an\u00e1lisis<\/strong>\u00a0que especifiquen el tipo y etapa del c\u00e1ncer.<\/p>\n

\u201cNo sabemos si es el santo grial para todos los diagn\u00f3sticos de c\u00e1ncer<\/strong>, pero parece realmente interesante como un marcador universal de c\u00e1ncer incre\u00edblemente simple, y como una tecnolog\u00eda accesible y econ\u00f3mica que no requiere equipos de laboratorio complicados como el ADN secuenciaci\u00f3n\u201d, dijo el profesor Trau.<\/p>\n

El equipo estaba trabajando para desarrollar a\u00fan m\u00e1s la tecnolog\u00eda y la licencia con un socio comercial. <\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"
