TY - JOUR T1 - ONe step forward toward identification of the genetic signature of glioblastomas AU - Pasche B, Myers RM Y1 - 2009/07/15 N1 - 10.1001/jama.2009.1023 JO - JAMA SP - 325 EP - 326 VL - 302 IS - 3 N2 - Cancer is a disease of the genome at the level of gene expression, epigenetic modifications such as DNA methylation, and DNA alterations. For more than 3 decades, many lines of research have shown that acquisition of genetic changes is a major and required step in the development of most cancers. First, ionizing radiation and chemicals that damage DNA and cause mutations also cause cancer.1 Second, genomic alterations such as translocations that result in the production of a specific gene fusion product are associated with some types of cancer. Such is the case for the translocations between chromosomes 9 and 22 in chronic myeloid leukemia and the translocation between chromosomes 15 and 17 in acute promyelocytic leukemia.2 Third, the introduction of genomic DNA from human cancer cells into normal cells can render the normal cells cancerous.3 SN - 0098-7484 M3 - doi: 10.1001/jama.2009.1023 UR - http://dx.doi.org/10.1001/jama.2009.1023 ER -
