L\u2019estudi liderat per investigadors\/es de l\u2019Institut Catal\u00e0 d\u2019Oncologia (ICO), l\u2019Institut d\u2019Investigaci\u00f3 Biom\u00e8dica de Bellvitge (IDIBELL), l’Institut de Recerca Germans Trias i Pujol (IGTP), i el Translational Genomics Research Institute d\u2019Estats Units, s\u2019ha publicat a la revista \u2018Genome Medicine<\/strong><\/a>\u2019 i representa un pas significatiu cap a una millor comprensi\u00f3 de com les alteracions en el sistema immunol\u00f2gic faciliten l’aparici\u00f3 del c\u00e0ncer.<\/p>\n

El sistema immunitari \u00e9s el responsable de mantenir la integritat i funci\u00f3 de l’organisme protegint-nos cont\u00ednuament d\u2019atacs ex\u00f2gens, com poden ser els virus, i end\u00f2gens, en aquest cas, el c\u00e0ncer. Aix\u00f2, li atorga un paper central en la inhibici\u00f3 de la carcinog\u00e8nesi i la seva alteraci\u00f3 pot augmentar el risc de c\u00e0ncer en permetre la proliferaci\u00f3 de c\u00e8l\u00b7lules malignes. Tot i aix\u00f2, la base gen\u00e8tica que influeix en aquesta regulaci\u00f3 era generalment desconeguda fins ara. Ara, aquesta investigaci\u00f3 obre noves vies per al desenvolupament de m\u00e8todes de prevenci\u00f3 espec\u00edfics i dirigits a trav\u00e9s de ter\u00e0pies o intervencions que modulin la resposta immunol\u00f2gica.<\/p>\n

Els resultats del projecte senyalen a m\u00e9s de 1.000 gens que influeixen simult\u00e0niament en el sistema immunitari i el risc de c\u00e0ncer. Aquests gens que afecten a m\u00e9s d\u2019una caracter\u00edstica de l\u2019organisme, anomenats pleiotr\u00f2pics, es troben sovint associats al control del desenvolupament del sistema hematol\u00f2gic i la regulaci\u00f3 dels tel\u00f2mers.<\/p>\n

Per una banda, l\u2019alteraci\u00f3 de l\u2019hematopoesi associada a c\u00e0ncer es vincula principalment amb anomalies de c\u00e8l\u00b7lules del tipus mieloide, com els neutr\u00f2fils o els eosin\u00f2fils. En aquest sentit, l\u2019estudi ha determinat un paper protector espec\u00edfic dels eosin\u00f2fils contra el desenvolupament de c\u00e0ncers comuns a la poblaci\u00f3 general. Per altra banda, els tel\u00f2mers s\u00f3n estructures situades als extrems dels cromosomes que protegeixen el material gen\u00e8tic i que es desgasten amb el pas del temps. Pel que, alteracions dels tel\u00f2mers, s\u2019associen a diferents patologies o condicions, incloent-hi el c\u00e0ncer i l\u2019envelliment.<\/p>\n

A m\u00e9s, l\u2019estudi ha identificat possibles biomarcadors sanguinis de risc de c\u00e0ncer i inici de tumors. Aquests marcadors predictius es basen en petites seq\u00fc\u00e8ncies de RNA no-codificant que poden alterar la funci\u00f3 del sistema immunitari.<\/p>\n

El Dr. Rafael de Cid, co-responsable de l\u2019estudi i cap del projecte GCAT!Genomes for Life- IGTP, destaca la complexitat i la interconnexi\u00f3 de l’arquitectura del genoma hum\u00e0: \u201cLa recerca gen\u00e8tica centrada en trets biol\u00f2gics mesurables, senzills, pot ser una via per entendre les bases gen\u00e8tiques de trets m\u00e9s complexos, com el c\u00e0ncer<\/strong>\u201d.<\/p>\n

En resum, els autors subratllen la import\u00e0ncia del progr\u00e9s en la recerca gen\u00e8tica per millorar la prevenci\u00f3 i el tractament del c\u00e0ncer, cap a una personalitzaci\u00f3 d’aquestes intervencions.<\/p>\n
