    • We report the generation and analysis of functional data from multiple, diverse experiments performed on a targeted 1% of the human genome as part of the pilot phase of the ENCODE Project. These data have been further integrated and augmented by a number of evolutionary and computational analyses. Together, our results advance the collective knowledge about human genome function in several major areas. First, our studies provide convincing evidence that the genome is pervasively transcribed, such that the majority of its bases can be found in primary transcripts, including non-protein-coding transcripts, and those that extensively overlap one another. Second, systematic examination of transcriptional regulation has yielded new understanding about transcription start sites, including their relationship to specific regulatory sequences and features of chromatin accessibility and histone modification. Third, a more sophisticated view of chromatin structure has emerged, including its inter-relationship with DNA replication and transcriptional regulation. Finally, integration of these new sources of information, in particular with respect to mammalian evolution based on inter- and intra-species sequence comparisons, has yielded new mechanistic and evolutionary insights concerning the functional landscape of the human genome. Together, these studies are defining a path for pursuit of a more comprehensive characterization of human genome function.

  • Outcome of treatment in children with hypodiploid acute lymphoblastic leukemia.
  • 2007
  • Ingår i: Blood. - 0006-4971. ; 110:4, s. 1112-5
  • Tidskriftsartikel (refereegranskat)abstract
    • One-hundred thirty-nine patients with acute lymphoblastic leukemia (ALL) and hypodiploidy (fewer than 45 chromosomes) were collected from 10 different national ALL study groups and single institutions. Patients were stratified by modal chromosome number into 4 groups: 24 to 29 (N = 46); 33 to 39 (N = 26); 40 to 43 (N = 13); and 44 (N = 54) chromosomes. Nine patients were Philadelphia chromosome (Ph) positive (4 cases: 44 chromosomes; 5 cases: 40-43 chromosomes) and were not considered further. Event-free survival (EFS) and overall survival (OS) of the remaining 130 patients were 38.5% +/- 4.4% and 49.8% +/- 4.2% at 8 years, respectively. There were no significant differences in outcome between patients with 24 to 29, 33 to 39, or 40 to 43 chromosomes. Compared with patients with fewer than 44 chromosomes, patients with 44 chromosomes had a significantly better EFS (P = .01; 8-year estimate, 52.2% vs 30.1%) and OS (P = .017; 69% vs 37.5%). For patients with 44 chromosomes, monosomy 7, the presence of a dicentric chromosome, or both predicted a worse EFS but similar OS. Doubling of the hypodiploid clone occurred in 32 patients (24-29 chromosomes [n = 25] and 33-39 chromosomes [n = 7]) and had no prognostic implication. Children and adolescents with ALL and hypodiploidy with fewer than 44 chromosomes have a poor outcome despite contemporary therapy.
