RNA-Seq is a recently developed approach to transcriptome profiling that uses deep-sequencing technologies. Studies using this method have already altered our view of the extent and complexity of eukaryotic transcriptomes. RNA-Seq also provides a far more precise measurement of levels of transcripts and their isoforms than other methods. This article(More)
The identification of untranslated regions, introns, and coding regions within an organism remains challenging. We developed a quantitative sequencing-based method called RNA-Seq for mapping transcribed regions, in which complementary DNA fragments are subjected to high-throughput sequencing and mapped to the genome. We applied RNA-Seq to generate a(More)
Nitric oxide (NO) and peroxynitrite, formed from NO and superoxide anion, have been implicated as mediators of neuronal damage following focal ischemia, but their molecular targets have not been defined. One candidate pathway is DNA damage leading to activation of the nuclear enzyme, poly(ADP-ribose) polymerase (PARP), which catalyzes attachment of ADP(More)
Single-molecule sequencing instruments can generate multikilobase sequences with the potential to greatly improve genome and transcriptome assembly. However, the error rates of single-molecule reads are high, which has limited their use thus far to resequencing bacteria. To address this limitation, we introduce a correction algorithm and assembly strategy(More)
Poly(ADP-ribosyl)ation is catalyzed by NAD+: protein(ADP-ribosyl) transferase (ADPRT), a chromatin-associated enzyme which, in the presence of DNA breaks, transfers ADP-ribose from NAD+ to nuclear proteins. This post-translational modification has been implicated in many fundamental processes, like DNA repair, chromatin stability, cell proliferation, and(More)
The Pax5 gene, coding for the transcription factor BSAP, was mutated in the mouse germline by targeted disruption. Homozygous mutant mice were born alive, became growth retarded, and usually died within three weeks. About 5% of mutants survived to adulthood and were fertile, but severely runted. Morphogenesis of the posterior midbrain was affected as early(More)
Transcriptomics studies often rely on partial reference transcriptomes that fail to capture the full catalogue of transcripts and their variations. Recent advances in sequencing technologies and assembly algorithms have facilitated the reconstruction of the entire transcriptome by deep RNA sequencing (RNA-seq), even without a reference genome. However,(More)
MLL (for mixed-lineage leukemia) is a proto-oncogene that is mutated in a variety of human leukemias. Its product, a homolog of Drosophila melanogaster trithorax, displays intrinsic histone methyltransferase activity and functions genetically to maintain embryonic Hox gene expression. Here we report the biochemical purification of MLL and demonstrate that(More)
The receptor for insulin-like growth factor type 2, also known as the cation-independent mannose-6-phosphate receptor (Igf2/Mpr), is a multifunctional receptor thought to play a role in lysosomal targeting, cell growth and signal transduction. Igf2/Mpr has been mapped to the mouse Tme locus and shown to be an imprinted gene, which further suggests a role in(More)
Lack of JunB, an immediate early gene product and member of the AP-1 transcription factor family causes embryonic lethality between E8.5 and E10.0. Although mutant embryos are severely retarded in growth and development, cellular proliferation is apparently not impaired. Retardation and embryonic death are caused by the inability of JunB-deficient embryos(More)
