Project description:We report the application of next generation sequencing technology for high-throughput profiling of cytosine methylation in adult rat liver tissue. To investigate the role of intragenic methylation, we generated the first high resolution methylation map of rat liver tissue and compared it with the proteome of the same rat tissue.

Project description:We have discovered that the alternative splice form of MYH7b is a regulatory non-coding RNA in the human heart. This dataset contains a forced expression of a peptide encoded by a short ORF at the beginning of the alternate splice form (MYH7b_sp) in cardiomyocytes.

Project description:<p>Non-coding regions comprise most of the human genome and harbor a significant fraction of risk alleles for neuropsychiatric diseases, yet their functions remain poorly defined. We created a high-resolution map of non-coding elements involved in human cortical neurogenesis by contrasting chromatin accessibility and gene expression in the germinal zone and cortical plate of the developing cerebral cortex. To obtain a high resolution depiction of chromatin structure and gene expression in developing human fetal cortex, we dissected the post-conception week (PCW) 15-17 human neocortex into two major anatomical divisions to distinguish between proliferating neural progenitors and post mitotic neurons: (1) GZ: the neural progenitor-enriched region encompassing the ventricular zone (VZ), subventricular zone (SVZ), and intermediate zone (IZ) and (2) CP: the neuron-enriched region containing the subplate (SP), cortical plate (CP), and marginal zone (MZ). Tissues were obtained from three independent donors and three to four technical replicates from each tissue were processed for ATAC-seq to define the landscape of accessible chromatin and RNA-seq for genome-wide gene expression profiling.</p>

Project description:In a genome-wide screen of human cancer cell lines, we identified homozygous intragenic microdeletions involving genes encoding components of the apical-basal cell polarity complexes. Among these, PARD3 is disrupted in cell lines and primary tumors from squamous carcinomas and glioblastomas. Reconstituting PARD3 expression in both cell types restores tight junctions and retards contact-dependent proliferation. Searching specifically for small intragenic microdeletions using high-resolution genomic arrays may be complementary to other genomic deletion screens and resequencing efforts in identifying new tumor suppressor genes. 444 human cancer cell lines of diverse tissue origin and 6 EBV-transformed B-lymphocyte cell lines (Coriell Institute for Medical Research, Camden, NJ) as controls.

Project description:Despite 20 years since its discovery, the gene responsible for Huntington’s Disease, HTT, has still not had its function or transcriptional profile completely characterized. In response to a recent report by Ruzo et al. of several novel splice forms of HTT in human embryonic stem cell lines, we have analyzed a set of mRNA sequencing datasets from post mortem human brain from Huntington’s disease, Parkinson’s disease, and neurologically normal control subjects to evaluate support for previously observed and to identify novel splice patterns. A custom analysis pipeline produced supporting evidence for some of the results reported by two previous studies of alternative isoforms as well as identifying previously unreported splice patterns. All of the alternative splice patterns were of relatively low abundance compared to the canonical splice form.

Project description:Spliced messages constitute one-fourth of expressed mRNAs in the yeast Saccharomyces cerevisiae, and most mRNAs in metazoans. Splicing requires 5' splice site (5'SS), branch point (BP), and 3' splice site (3'SS) elements, but the role of the BP in splicing control is poorly understood because BP identification remains difficult. We developed a high-throughput method, Branch-seq, to map BP and 5'SS of isolated RNA lariats. Applied to S. cerevisiae, Branch-seq detected 76% of expressed, annotated BPs and identified a comparable number of novel BPs. We used RNA-seq to confirm associated 3'SS locations, identifying some 200 novel splice junctions, including an AT-AC intron. We show that several yeast introns use two or even three different BPs, with effects on 3'SS choice, protein coding potential, or RNA stability and identify novel introns whose splicing changes during meiosis or in response to stress. Together, these findings reveal BP-based regulation and demonstrate unanticipated complexity of splicing in yeast. 1 Lariat-seq experiment library. 3 barcoded Branch-seq libraries that make up one experiment. 26 RNA-seq samples, 2 biological replicates of each.

Project description:Deconvolution analysis using Rpb1 ChIP-chip results distinguishes the Cdc10 bindings at the Rpb1-poor loci (promoters) from those at the Rpb1-rich loci (intragenic sequences). Importantly, Res1 binding at the Rpb1-poor loci, but not at the Rpb1-rich loci, are dependent on the Cdc10 function, suggesting a distinct binding mechanism. Most Cdc10 promoter bindings at the Rpb1-poor loci are associated with the G1/S-phase genes. While Res1 or Res2 is found at both the Cdc10 promoter and intragenic binding sites, Rep2 appears to be absent at the Cdc10 promoter binding sites but present at the intragenic sites. Time-course ChIP-chip analysis demonstrates that Rep2 is temporally accumulated at the coding region of the MBF-target genes, resembling the RNAP-II occupancies. We analyzed MBF binding sites using Nimblegen arrays.
