    Mechanism-Anchored Profiling Derived from Epigenetic Networks Predicts Outcome in Acute Lymphoblastic Leukemia Xinan Yang, PhD1, Yong Huang, MD1, James L Chen, MD1, Jianming Xie, MSc2, Xiao Sun, PhD2, Yves A Lussier, MD1,3,4§ 1Center for Biomedical Informatics and Section of Genetic Medicine, Department of Medicine, The University of Chicago, Chicago, IL 60637 USA 2State Key Laboratory of Bioelectronics, Southeast University, 210096 Nanjing, P.R.China 3The University of Chicago Cancer Research Center, and The Ludwig Center for Metastasis Research, The University of Chicago, Chicago, IL 60637 USA 4The Institute for Genomics and Systems Biology, and the Computational Institute, The University of Chicago, Chicago, IL 60637 USA §Corresponding author Email addresses: XY: [email protected] YH: [email protected] JC: [email protected] JX: [email protected] XS: [email protected] YL: [email protected] - 1 - Abstract Background Current outcome predictors based on “molecular profiling” rely on gene lists selected without consideration for their molecular mechanisms. This study was designed to demonstrate that we could learn about genes related to a specific mechanism and further use this knowledge to predict outcome in patients – a paradigm shift towards accurate “mechanism-anchored profiling”. We propose a novel algorithm, PGnet, which predicts a tripartite mechanism-anchored network associated to epigenetic regulation consisting of phenotypes, genes and mechanisms. Genes termed as GEMs in this network meet all of the following criteria: (i) they are co-expressed with genes known to be involved in the biological mechanism of interest, (ii) they are also differentially expressed between distinct phenotypes relevant to the study, and (iii) as a biomodule, genes correlate with both the mechanism and the phenotype.

  • Instability of the Pseudoautosomal Boundary in House Mice
    Genetics: Early Online, published on April 26, 2019 as 10.1534/genetics.119.302232 Article/Investigation Instability of the pseudoautosomal boundary in house mice Andrew P Morgan∗, Timothy A Bell∗, James J Crowley∗; y; z, and Fernando Pardo-Manuel de Villena∗ ∗Department of Genetics and Lineberger Comprehensive Cancer Center, University of North Carolina, Chapel Hill, NC yDepartment of Psychiatry, University of North Carolina, Chapel Hill, NC zDepartment of Clinical Neuroscience, Karolinska Institutet, Stockholm, Sweden April 26, 2019 Corresponding authors: Andrew P Morgan ([email protected]) Fernando Pardo-Manuel de Villena ([email protected]) 5049C Genetic Medicine Building Department of Genetics University of North Carolina Chapel Hill NC 27599-7264 Keywords: meiosis, recombination, pseudoautosomal region, sex chromosome evolution 1 Copyright 2019. Abstract Faithful segregation of homologous chromosomes at meiosis requires pairing and recombination. In taxa with dimorphic sex chromosomes, pairing between them in the heterogametic sex is limited to a narrow inter- val of residual sequence homology known as the pseudoautosomal region (PAR). Failure to form the obligate crossover in the PAR is associated with male infertility in house mice (Mus musculus) and humans. Yet despite this apparent functional constraint, the boundary and organization of the PAR is highly variable in mammals, and even between subspecies of mice. Here we estimate the genetic map in a previously-documented ex- pansion of the PAR in the Mus musculus castaneus subspecies and show that the local recombination rate is 100-fold higher than the autosomal background. We identify an independent shift in the PAR boundary in the Mus musculus musculus subspecies and show that it involves a complex rearrangement but still recombines in heterozygous males.

  • Structural and Numerical Changes of Chromosome X in Patients with Esophageal Atresia
    European Journal of Human Genetics (2014) 22, 1077–1084 & 2014 Macmillan Publishers Limited All rights reserved 1018-4813/14 www.nature.com/ejhg ARTICLE Structural and numerical changes of chromosome X in patients with esophageal atresia Erwin Brosens*,1,2,5, Elisabeth M de Jong1,2,5, Tahsin Stefan Barakat3, Bert H Eussen1, Barbara D’haene4, Elfride De Baere4, Hannah Verdin4, Pino J Poddighe1, Robert-Jan Galjaard1, Joost Gribnau3, Alice S Brooks1, Dick Tibboel2 and Annelies de Klein1 Esophageal atresia with or without tracheoesophageal fistula (EA/TEF) is a relatively common birth defect often associated with additional congenital anomalies such as vertebral, anal, cardiovascular, renal and limb defects, the so-called VACTERL association. Yet, little is known about the causal genetic factors. Rare case reports of gastrointestinal anomalies in children with triple X syndrome prompted us to survey the incidence of structural and numerical changes of chromosome X in patients with EA/TEF. All available (n ¼ 269) karyotypes of our large (321) EA/TEF patient cohort were evaluated for X-chromosome anomalies. If sufficient DNA material was available, we determined genome-wide copy number profiles with SNP array and identified subtelomeric aberrations on the difficult to profile PAR1 region using telomere-multiplex ligation-dependent probe amplification. In addition, we investigated X-chromosome inactivation (XCI) patterns and mode of inheritance of detected aberrations in selected patients. Three EA/TEF patients had an additional maternally inherited X chromosome. These three female patients had normal random XCI patterns. Two male EA/TEF patients had small inherited duplications of the XY-linked SHOX (Short stature HOmeoboX-containing) locus.

  • Analyses of PDE-Regulated Phosphoproteomes Reveal Unique and Specific Camp Signaling Modules in T Cells
    Analyses of PDE-regulated phosphoproteomes reveal unique and specific cAMP signaling modules in T cells Michael-Claude G. Beltejar A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy University of Washington 2017 Reading Committee: Joseph Beavo, Chair Shao-en Ong Richard Gardner Program Authorized to Offer Degree: Molecular and Cellular Biology ©Copyright 2017 Michael-Claude G. Beltejar University of Washington Abstract Analyses of PDE-regulated phosphoproteomes reveal unique and specific cAMP signaling modules in T cells Michael-Claude G. Beltejar Chair of the Supervisory Committee: Professor Joseph A. Beavo Department of Pharmacology Specific functions for different cyclic nucleotide phosphodiesterases (PDEs) have not yet been identified in most cell types. Conventional approaches to study PDE function typically rely on measurements of global cAMP, general increases in cAMP-dependent protein kinase (PKA), or exchange protein activated by cAMP (EPAC) activity. Although newer approaches utilizing subcellularly-targeted FRET reporter sensors have helped to define more compartmentalized regulation of cAMP, PKA, and EPAC, they have limited ability to link this regulation to downstream effector molecules and biological functions. To address this problem, we used an unbiased, mass spectrometry based approach coupled with treatment using PDE isozyme- selective inhibitors to characterize the phosphoproteomes of the “functional pools” of cAMP/PKA/EPAC that are regulated by specific cAMP-PDEs (the PDE-regulated phosphoproteomes). In Jurkat cells we found multiple, distinct phosphoproteomes that differ in response to different PDE inhibitors. We also found that little phosphorylation occurs unless at least 2 different PDEs are concurrently inhibited in these cells. Moreover, bioinformatics analyses of these phosphoproteomes provides insight into the functional roles, mechanisms of action, and synergistic relationships among the different PDEs that coordinate cAMP-signaling cascades in these cells.

  • Dosage Regulation of the Active X Chromosome in Human Triploid Cells
    Dosage Regulation of the Active X Chromosome in Human Triploid Cells Xinxian Deng1, Di Kim Nguyen1, R. Scott Hansen2,3, Daniel L. Van Dyke4, Stanley M. Gartler2,3, Christine M. Disteche1,2* 1 Department of Pathology, University of Washington, Seattle, Washington, United States of America, 2 Department of Medicine, University of Washington, Seattle, Washington, United States of America, 3 Department of Genome Sciences, University of Washington, Seattle, Washington, United States of America, 4 Mayo Clinic College of Medicine, Rochester, Minnesota, United States of America Abstract In mammals, dosage compensation is achieved by doubling expression of X-linked genes in both sexes, together with X inactivation in females. Up-regulation of the active X chromosome may be controlled by DNA sequence–based and/or epigenetic mechanisms that double the X output potentially in response to autosomal factor(s). To determine whether X expression is adjusted depending on ploidy, we used expression arrays to compare X-linked and autosomal gene expression in human triploid cells. While the average X:autosome expression ratio was about 1 in normal diploid cells, this ratio was lower (0.81–0.84) in triploid cells with one active X and higher (1.32–1.4) in triploid cells with two active X’s. Thus, overall X- linked gene expression in triploid cells does not strictly respond to an autosomal factor, nor is it adjusted to achieve a perfect balance. The unbalanced X:autosome expression ratios that we observed could contribute to the abnormal phenotypes associated with triploidy. Absolute autosomal expression levels per gene copy were similar in triploid versus diploid cells, indicating no apparent global effect on autosomal expression.

  • A Factor Model to Analyze Heterogeneity in Gene Expression BMC Bioinformatics 2010, 11:368
    Blum et al. BMC Bioinformatics 2010, 11:368 http://www.biomedcentral.com/1471-2105/11/368 METHODOLOGY ARTICLE Open Access AMethodology factor article model to analyze heterogeneity in gene expression Yuna Blum*1,2,3, Guillaume Le Mignon1,2, Sandrine Lagarrigue1,2 and David Causeur3 Abstract Background: Microarray technology allows the simultaneous analysis of thousands of genes within a single experiment. Significance analyses of transcriptomic data ignore the gene dependence structure. This leads to correlation among test statistics which affects a strong control of the false discovery proportion. A recent method called FAMT allows capturing the gene dependence into factors in order to improve high-dimensional multiple testing procedures. In the subsequent analyses aiming at a functional characterization of the differentially expressed genes, our study shows how these factors can be used both to identify the components of expression heterogeneity and to give more insight into the underlying biological processes. Results: The use of factors to characterize simple patterns of heterogeneity is first demonstrated on illustrative gene expression data sets. An expression data set primarily generated to map QTL for fatness in chickens is then analyzed. Contrarily to the analysis based on the raw data, a relevant functional information about a QTL region is revealed by factor-adjustment of the gene expressions. Additionally, the interpretation of the independent factors regarding known information about both experimental design and genes shows that some factors may have different and complex origins. Conclusions: As biological information and technological biases are identified in what was before simply considered as statistical noise, analyzing heterogeneity in gene expression yields a new point of view on transcriptomic data.

  • REVIEW Specificity and Spatial Dynamics of Protein Kinase A
    271 REVIEW Specificity and spatial dynamics of protein kinase A signaling organized by A-kinase-anchoring proteins Guillaume Pidoux and Kjetil Taske´n Biotechnology Centre of Oslo and Centre for Molecular Medicine, Nordic EMBL Partnership, University of Oslo, PO Box 1125, Blindern, N-0317 Oslo, Norway (Correspondence should be addressed to K Taske´n; Email: [email protected]) Abstract Protein phosphorylation is the most common post-translational modification observed in cell signaling and is controlled by the balance between protein kinase and phosphatase activities. The cAMP–protein kinase A (PKA) pathway is one of the most studied and well-known signal pathways. To maintain a high level of specificity, the cAMP–PKA pathway is tightly regulated in space and time. A-kinase-anchoring proteins (AKAPs) target PKA to specific substrates and distinct subcellular compartments providing spatial and temporal specificity in the mediation of biological effects controlled by the cAMP–PKA pathway. AKAPs also serve as scaffolding proteins that assemble PKA together with signal terminators such as phosphoprotein phosphatases and cAMP-specific phosphodiesterases as well as components of other signaling pathways into multiprotein-signaling complexes. Journal of Molecular Endocrinology (2010) 44, 271–284 Introduction spatiotemporal regulation of cellular signaling and constitutes a concept by which a common signaling In multicellular organisms, cell signaling constitutes pathway can perform many different functions. One of communication mechanisms between and inside cells the best-characterized signal transduction pathways is to ensure coordinated behavior of the organism and the cAMP-signaling pathway where ligand binding to G to regulate various biological processes such as cell protein-coupled receptors (GPCRs) via G proteins and proliferation, development, metabolism, gene adenylyl cyclase (AC) leads to an intracellular increase expression, and other more specialized functions of in the levels of the second messenger cAMP.
