As\u00ed, cuando hablamos de la actividad de nuestro genoma, en realidad nos estamos refiriendo a la expresi\u00f3n de los genes en este sentido de la doble cadena de ADN. <b><br \/> Sin embargo, desde hace un tiempo, se conoce la existencia de unas cuantas secuencias de ADN \u2018rebelde\u2019 que se activan al rev\u00e9s: de derecha a izquierda. Son conocidos como transcritos Antisentido. <b><br \/> Se sabe muy poco de sus funciones, pero hoy un trabajo co-dirigido por Manel Esteller, Director del Programa de Epigen\u00e9tica y Biolog\u00eda del Cancer (PEBC) del Instituto de Investigaci\u00f3n Biom\u00e9dica de Bellvitge (IDIBELL), Profesor de Gen\u00e9tica de la Universidad de Barcelona e Investigador ICREA y Sonia Guil del mismo departamento proporciona nuevas pistas y mecanismos para entender sus funciones y sus alteraciones en c\u00e1ncer. <b><br \/> El hallazgo se publica en la edici\u00f3n avanzada de revista <em>Proceedings of the National Academy of Sciences (PNAS)<\/em>. <b><br \/> <b><br \/> \u201cSi imaginamos una carretera por donde todos los coches van en el mismo sentido, hemos encontrado un coche que va en sentido contrario y choca contra uno de ellos\u201d explica Manel Estelller sobre el resultado de la investigaci\u00f3n publicada en <em>PNAS.<\/em> <em><b><br \/><\/em>\u201cConcretamente\u201d a\u00f1ade \u201ceste transcrito antisentido regula a un gen expresado de forma m\u00e1s normal que se llama Vimentina, asociada al proceso de invasi\u00f3n tumoral.
