We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated. -
Comprehensive Genome Methylation Analysis in Bladder Cancer: Identification and Validation of Novel Methylated Genes and Application of These As Urinary Tumor Markers
Published OnlineFirst July 25, 2011; DOI: 10.1158/1078-0432.CCR-10-2659 Clinical Cancer Human Cancer Biology Research Comprehensive Genome Methylation Analysis in Bladder Cancer: Identification and Validation of Novel Methylated Genes and Application of These as Urinary Tumor Markers Thomas Reinert1, Charlotte Modin1, Francisco M. Castano1, Philippe Lamy1, Tomasz K. Wojdacz4, Lise Lotte Hansen4, Carsten Wiuf3, Michael Borre2, Lars Dyrskjøt1, and Torben F. Ørntoft1 Abstract Purpose: Epigenetic alterations are common and can now be addressed in a parallel fashion. We investigated the methylation in bladder cancer with respect to location in genome, consistency, variation in metachronous tumors, impact on transcripts, chromosomal location, and usefulness as urinary markers. Experimental Design: A microarray assay was utilized to analyze methylation in 56 samples. Inde- pendent validation was conducted in 63 samples by a PCR-based method and bisulfite sequencing. The methylation levels in 174 urine specimens were quantified. Transcript levels were analyzed using expression microarrays and pathways were analyzed using dedicated software. Results: Global methylation patterns were established within and outside CpG islands. We validated methylation of the eight tumor markers genes ZNF154 (P < 0.0001), HOXA9 (P < 0.0001), POU4F2 (P < 0.0001), EOMES (P ¼ 0.0005), ACOT11 (P ¼ 0.0001), PCDHGA12 (P ¼ 0.0001), CA3 (P ¼ 0.0002), and PTGDR (P ¼ 0.0110), the candidate marker of disease progression TBX4 (P < 0.04), and other genes with stage-specific methylation. The methylation of metachronous tumors was stable and targeted to certain pathways. The correlation to expression was not stringent. Chromosome 21 showed most differential methylation (P < 0.0001) and specifically hypomethylation of keratins, which together with keratin-like proteins were epigenetically regulated. -

Department of Oncology-Pathology, Karolinska Institutet, Stockholm, 171 77, Sweden 2. International Research Center, A.C. Camargo Cancer Center, São Paulo, Brazil # Equally contributing authors * Correspondence: Laia Masvidal ([email protected]), Glaucia Hajj ([email protected]) and Ola Larsson ([email protected]) ABSTRACT Polysome-profiling is commonly used to study genome wide patterns of translational efficiency, i.e. the translatome. The standard approach for collecting efficiently translated polysome-associated RNA results in laborious extraction of RNA from a large volume spread across multiple fractions. This property makes polysome-profiling inconvenient for larger experimental designs or samples with low RNA amounts such as primary cells or frozen tissues. To address this we optimized a non-linear sucrose gradient which reproducibly enriches for mRNAs associated with >3 ribosomes in only one or two fractions, thereby reducing sample handling 5-10 fold. The technique can be applied to cells and frozen tissue samples from biobanks, and generates RNA with a quality reflecting the starting material. When coupled with smart-seq2, a single-cell RNA sequencing technique, translatomes from small tissue samples can be obtained. Translatomes acquired using optimized non-linear gradients are very similar to those obtained when applying linear gradients. -

Prediction of Host-Virus Interaction Networks

Doolittle A dissertation submitted to the faculty of the University of North Carolina at Chapel Hill in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Curriculum of Bioinformatics and Computational Biology. Chapel Hill 2012 Approved by: Tim Elston, PhD Shawn Gomez, Eng.Sc.D. Klaus Hahn, PhD Keith Burridge, PhD Anne Taylor, PhD Jennifer Webster-Cyriaque, PhD ©2012 Janet M. Doolittle ALL RIGHTS RESERVED ii ABSTRACT JANET DOOLITTLE: Prediction of host-virus interaction networks (Under the direction of Shawn Gomez) As with other viral pathogens, HIV-1 and dengue virus (DENV) are dependent on their hosts for the bulk of the functions necessary for viral survival and replication. Thus, successful infection depends on the pathogen's ability to manipulate the biological pathways and processes of the organism it infects, while avoiding elimination by the immune system. Protein-protein interactions are one avenue through which viruses can connect with and exploit these host cellular pathways and processes. We developed a computational approach to predict interactions between HIV and human proteins based on structural similarity of 9 HIV-1 proteins to human proteins having known interactions. Using functional data from RNAi studies as a filter, we generated over 2,000 interaction predictions between HIV proteins and 406 unique human proteins. Additional filtering based on Gene Ontology cellular component annotation reduced the number of predictions to 502 interactions involving 137 human proteins. We find numerous known interactions as well as novel interactions showing significant functional relevance based on supporting Gene Ontology and literature evidence. -

Efficient Analysis of Mammalian Polysomes in Cells and Tissues
TOOLS AND RESOURCES Efficient analysis of mammalian polysomes in cells and tissues using Ribo Mega-SEC Harunori Yoshikawa1†, Mark Larance1,2†, Dylan J Harney2, Ramasubramanian Sundaramoorthy1, Tony Ly1,3, Tom Owen-Hughes1, Angus I Lamond1* 1Centre for Gene Regulation and Expression, School of Life Sciences, University of Dundee, Dundee, United Kingdom; 2Charles Perkins Centre, School of Life and Environmental Sciences, University of Sydney, Sydney, Australia; 3Wellcome Centre for Cell Biology, University of Edinburgh, Edinburgh, United Kingdom Abstract We describe Ribo Mega-SEC, a powerful approach for the separation and biochemical analysis of mammalian polysomes and ribosomal subunits using Size Exclusion Chromatography and uHPLC. Using extracts from either cells, or tissues, polysomes can be separated within 15 min from sample injection to fraction collection. Ribo Mega-SEC shows translating ribosomes exist predominantly in polysome complexes in human cell lines and mouse liver tissue. Changes in polysomes are easily quantified between treatments, such as the cellular response to amino acid starvation. Ribo Mega-SEC is shown to provide an efficient, convenient and highly reproducible method for studying functional translation complexes. We show that Ribo Mega-SEC is readily combined with high-throughput MS-based proteomics to characterize proteins associated with polysomes and ribosomal subunits. It also facilitates isolation of complexes for electron microscopy and structural studies. *For correspondence: DOI: https://doi.org/10.7554/eLife.36530.001 [email protected] †These authors contributed equally to this work Introduction Competing interests: The The ribosome is a large RNA-protein complex, comprising four ribosomal RNAs (rRNAs) and >80 authors declare that no ribosomal proteins (RPs), which coordinates mRNA-templated protein synthesis.
