Colonbiome<\/a>. Aquest gran projecte t\u00e9 per objectiu buscar marcadors de la microbiota que puguin servir per a la detecci\u00f3 preco\u00e7 del c\u00e0ncer de c\u00f2lon. Per fer-ho, es recolliran bi\u00f2psies de c\u00f2lon i mostres de femta de pacients sans i pacients amb diferents fases de c\u00e0ncer colorectal, despr\u00e9s se\u2019n seq\u00fcenciar\u00e0 el genoma de la microbiota per identificar les difer\u00e8ncies entre els grups.<\/p>\n <\/p>\n
Dades a l\u2019abast de tothom<\/h4>\n
<\/p>\n
Totes les dades obtingudes en aquest estudi pilot han estat introdu\u00efdes en la European Nucleotide Archive, una base de dades p\u00fablica i col\u00b7laborativa, on es comparteixen seq\u00fc\u00e8ncies gen\u00f2miques de tota mena per a l\u2019aprofitament de tota la comunitat cient\u00edfica. A m\u00e9s, tots els resultats d\u2019aquesta primera prova pilot han estat publicats a la revista Scientific Data, revista tamb\u00e9 p\u00fablica, on s\u2019hi han detallat tant les seq\u00fc\u00e8ncies com les f\u00f3rmules d\u2019an\u00e0lisi bioinform\u00e0tic utilitzades.<\/p>\n
Aquest estudi no nom\u00e9s pret\u00e9n ser \u00fatil per als futurs treballs del grup, sin\u00f3 que gr\u00e0cies al seu car\u00e0cter obert i p\u00fablic pret\u00e9n ser una ajuda a tots aquells grups de recerca que estiguin realitzant an\u00e0lisis similars o provant noves eines bioinform\u00e0tiques, als quals se\u2019ls posa a l\u2019abast tots els resultats obtinguts. A m\u00e9s, els investigadors asseguren que tamb\u00e9 faran p\u00fablics tots els detalls dels estudis posteriors, per aix\u00ed seguir contribuint en la col\u00b7laboraci\u00f3 i l\u2019aven\u00e7 del camp.<\/p>\n

Els dos m\u00e8todes de seq\u00fcenciaci\u00f3<\/h4>\n
<\/p>\n
En l\u2019estudi s\u2019han comparat dos m\u00e8todes de seq\u00fcenciaci\u00f3: el 16s i el Shotgun. El primer desxifra la seq\u00fc\u00e8ncia d\u2019un sol gen dels microorganismes, mentre que el segon ens dona la seq\u00fc\u00e8ncia completa de tot el genoma. Tot i que en seq\u00fcenciar un \u00fanic gen perdem resoluci\u00f3, pot resultar m\u00e9s econ\u00f2mic. A m\u00e9s, el fet de seq\u00fcenciar un gen nom\u00e9s present en la microbiota ens permet analitzar mostres de bi\u00f2psies sense que el genoma hum\u00e0 hi interfereixi.<\/p>\n
Addicionalment, la prova pilot ha mostrat que ambdues t\u00e8cniques s\u00f3n consistents. Tot i que la seq\u00fcenciaci\u00f3 completa \u00e9s m\u00e9s sensible i hi distingim m\u00e9s esp\u00e8cies de microorganismes, en cap moment contradiu els resultats obtinguts en seq\u00fcenciar un \u00fanic gen.<\/p>\n","protected":false},"excerpt":{"rendered":"
