    摘要: Oligodendrogliomas are the second most common malignant brain tumor in adults. These tumors often contain a chromosomal abnormality involving a pericentromeric fusion of chromosomes 1 and 19, resulting in losses of the entire short arm of the former and the long arm of the latter. To identify the molecular genetic basis for this alteration, we performed exomic sequencing of seven anaplastic oligodendrogliomas with chromosome 1p and 19q losses. Among other changes, we found that that CIC (homolog of the Drosophila gene capicua) on chromosome 19q was somatically mutated in six of the seven cases and that FUBP1 (far upstream element (FUSE) binding protein) on chromosome 1p was somatically mutated in two of the seven cases. Examination of 27 additional oligodendrogliomas revealed 12 and 3 more tumors with mutations of CIC and FUBP1, respectively, 58% of which were predicted to result in truncations of the encoded proteins. These results suggest a critical role for these genes in the biology and pathology of oligodendrocytes.

    摘要: We determined the sequence of ATRX and DAXX in 447 cancers from various sites. We found mutations most commonly in pediatric glioblastoma multiformae (GBM) (11.1%), adult GBM (6.5%), oligodendrogliomas (7.7%) and medulloblastomas (1.5%); and showed that Alternative Lengthening of Telomeres (ALT), a telomerase-independent telomere maintenance mechanism found in cancers that have not activated telomerase, perfectly correlated with somatic mutations of either gene. In contrast, neuroblastomas, and adenocarcinomas of the ovary, breast, and pancreas were negative for mutations in ATRX and DAXX. Alterations in ATRX or DAXX define a specific molecular pathway that is closely associated with an alternative telomere maintenance function in human cancers.

    摘要: Human cancer is caused by the accumulation of mutations in oncogenes and tumor suppressor genes. To catalogue the genetic changes that occur during tumorigenesis, we isolated DNA from 11 breast and 11 colorectal tumors and determined the sequences of the genes in the Reference Sequence database in these samples. Based on analysis of exons representing 20,857 transcripts from 18,191 genes, we conclude that the genomic landscapes of breast and colorectal cancers are composed of a handful of commonly mutated gene “mountains” and a much larger number of gene “hills” that are mutated at low frequency. We describe statistical and bioinformatic tools that may help identify mutations with a role in tumorigenesis. These results have implications for understanding the nature and heterogeneity of human cancers and for using personal genomics for tumor diagnosis and therapy.
