RNA Maps Reveal New RNA Classes and a Possible Function for Pervasive Transcription

ABSTRACT: Significant fractions of eukaryotic genomes give rise to RNA, much of which is unannotated and has reduced protein-coding potential. The genomic origins and the relations of human nuclear and cytosolic polyadenylated RNAs longer than 200 nucleotides and whole-cell RNAs less than 200 nt are investigated in this genome-wide study. Subcellular addresses for nucleotides present in detected RNAs were assigned, and their potential processing into short RNAs was investigated. Taken together, these observations suggest a role for some unannotated RNAs as primary transcripts for the production of short RNAs. Three novel potentially functional classes of RNAs have been identified, two of which are syntenically conserved and correlate with the expression state of protein-coding genes. These data support a highly interleaved organization of the human transcriptome.

Genome-wide empirical binding sites co-occupied by p53 and NF-kB in human cardiomyopathy

Project description:p53 and NF-kB are important transcription factors involved in the pathogenesis of cardiac hypertrophy and the progression to heart failure/dilatation. We report the genome-wide empirical binding sites co-occupied by the transcription factors in human dilated hearts. p53-NF-kB sequential chromatin immunoprecipitation and high-throughput sequencing were performed using tissues from control and diseased hearts. These data may facilitate the discovery of mechanisms by which transcription factors cooperate in close proximity or a multi-molecular complex at a cis-regulatory element to control gene expression.

Encyclopedia of C. elegans 3' UTRs and their regulatory elements

Project description:The 3' untranslated region (3'UTR) constitutes a major site of post-transcriptional regulation of gene expression. Sequence elements in the 3'UTR interact with trans-acting regulators such as microRNAs that affect translation and stability. The overall aim is to use a 3'RACE cloning-sequencing stragety to identify the 3'UTRs of C. elegans transcripts and explore their heterogeneity in different developmental stages and tissues.

Project description:A copy-number variation (CNV) analysis was run on 40 CEU and YRI samples across an array set tiling across the human genome. The array contained 42 million oligos spread across 20 arrays. The final design provided 1 probe per 50bp average density across the genome.

High-throughput pyrosequencing of plant virus small RNAs

Project description:Plant virus infection involves the production of viral small RNAs (vsRNAs) with the potential to associate with distinct Argonaute (AGO)-containing silencing complexes and mediate diverse silencing effects on RNA and chromatin. We used multiplexed, high-throughput pyrosequencing to profile populations of vsRNAs from plants infected with viruses from different genera. Sense and antisense vsRNAs of 20 to 24 nucleotides (nts) spread throughout the entire viral genomes in an overlapping configuration; virtually all genomic nucleotide positions were represented in the dataset. We present evidence to suggest that every genomic position could be a putative cleavage site for vsRNA formation, although viral genomes contain specific regions that serve as preferential sources of vsRNA production. Hotspots for vsRNAs of 21-, 22-, and 24-nt usually coincide in the same genomic regions, indicating similar target affinities among Dicer-like (DCL) enzymes. In the light of our results, the overall contribution of perfectly base paired double-stranded RNA and imperfectly base paired structures within single-stranded RNA to vsRNA formation is discussed. Our census of vsRNAs extends the current view of the distribution and composition of vsRNAs in virus-infected plants, and contributes to define a more comprehensive scenario of vsRNA biogenesis and their regulatory functions in plants Raw data files are available on our FTP site: ftp://ftp.ncbi.nlm.nih.gov/pub/geosup/Series/GSE16996
