De fet, es considera un oncogen i encara no existeixen ter\u00e0pies dirigides contra la seva activitat.<\/p>\n<p><strong>Com actua aquest gen per promoure la malaltia?<\/strong><\/p>\n<p>Com que atacar directament al MYC resulta molt complicat, l\u2019equip d\u2019investigadors\/es que ha\u00a0 participat en aquest estudi han buscat una altra estrat\u00e8gia. Han identificat prote\u00efnes que s\u00f3n necess\u00e0ries per tal de que el gen MYC promogui el desenvolupament del tumor. Per fer-ho, han utilitzat una eina gen\u00e8tica anomenada CRISPR per veure quins components s\u00f3n cr\u00edtics en les accions de MYC en el c\u00e0ncer de mama i han descobert una prote\u00efna, anomenada R-Loops, que pot causar canvis en l\u2019activitat de MYC, i una altra prote\u00efna, anomenada Topoisomerasa 1 (TOP1), que regula l\u2019anterior.<\/p>\n<p>Aix\u00ed doncs, quan han desactivat TOP1, en les c\u00e8l\u00b7lules cancer\u00edgenes gr\u00e0cies al MYC, s\u2019ha pogut observar que les c\u00e8l\u00b7lules perdien la seva habilitat per a cr\u00e9ixer i dividir-se i, per tant, s\u2019ha trobat una debilitat espec\u00edfica. Aquest proc\u00e9s s\u2019ha pogut verificar en models de tumors en animals i els resultats han demostrat la seva efectivitat. Pel Dr Pujana, \u201caquest estudi obre una nova oportunitat de tractament dirigit contra una elevada proporci\u00f3 de tumors\u201d.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><em>L\u2019Institut d&#8217;Investigaci\u00f3 Biom\u00e8dica de Bellvitge (IDIBELL) \u00e9s un centre de recerca en biomedicina creat l\u2019any 2004.
