Meyer Cornellgrad 0058F 10073 METHODS FOR FUNCTIONAL INFERENCE IN THE PROTEOME AND INTERACTOME A Dissertation Presented to the Faculty of the Graduate School of Cornell University in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy by Michael Joseph Meyer January 2017 © 2017 Michael Joseph Meyer ALL RIGHTS RESERVED METHODS FOR FUNCTIONAL INFERENCE IN THE PROTEOME AND INTERACTOME Michael Meyer Cornell University 2017 Over the past several decades, biology has become an increasingly data-driven science. Due in large part to new techniques that allow massive collection of biological data, including next-generation sequencing and high-throughput experimental screening, many of the limitations currently facing the field are in the organization and interpretation of these data. In this dissertation, I present several computational methods and resources designed to organize and perform functional inference on these systems-level biological data sources. In Chapters 2 and 3, I describe the construction of a database and web tool to aid in foundational genomics research by providing predictions of interacting protein domains in interactomes and all-by-all conversions of popular variant identification formats. In Chapter 4, I describe the construction of the first whole-interactome protein interaction network in the fission yeast S. pombe, and, through comparisons with other complete networks in human and the budding yeast S. cerevisiae, demonstrate principles of functional evolution. Finally, in Chapters 5 and 6, I propose two new methods for functional genomic inference—an algorithm to predict cancer driver genes and mutations through 3D atomic clustering of somatic mutations and an ensemble machine learning method to predict the 3D interfaces of protein interactions by taking into account the evolutionary relationships and biophysical properties of proteins. Taken together, this suite of computational resources will help researchers interpret biological function on a genomic scale. BIOGRAPHICAL SKETCH Michael was born in 1989 to Joseph and Nicolette Meyer, and grew up in Worthington, Ohio as the eldest of three children. He graduated from Thomas Worthington High School in 2007 and attended the Massachusetts Institute of Technology from 2007 to 2011, where he earned his bachelor’s degree in Biological Engineering. In the summer of 2010 he interned at Ion Torrent, a startup DNA sequencing company founded by Dr. Jonathan Rothberg, where he helped develop the Ion Torrent Personal Genome Machine. He returned in the summer of 2011 after a successful buyout by Life Technologies. In 2011 he married his high school sweetheart, Sarai Meyer (Itagaki), and they moved to Ithaca, New York to begin their Ph.D.s at Cornell University. Michael entered the Tri- Institutional Training Program in Computational Biology and Medicine (CBM) and completed laboratory rotations at Cornell’s Ithaca campus and at the Weill Cornell Medical School in New York City. He ultimately joined the computational systems biology lab of Dr. Haiyuan Yu in the Weill Institute for Cell and Molecular Biology in Ithaca, where he completed the research presented in this dissertation. iii For my grandfathers v i ACKNOWLEDGEMENTS I am incredibly fortunate to have had the support of many people over the course of my life and studies. There are an awful lot of people to thank. But first, I’d like to acknowledge my incredible fortune to have been born in a time and place where scholarly aspirations are relevant and valued, without which none of this would have been possible. To my parents—Mom and Dad, thank you for giving me every chance to succeed, for investing in me, and for showing me how to be a good person. Mom, thank you for your unconditional love, home-cooked meals, and for giving me that problem-solving itch that I’m still trying to scratch. Dad, thank you pushing me, allowing me to learn from my mistakes, accept failure, and think for myself. And thank you both for being there from a distance to help me through these past five years. And to the rest of my family—thanks for putting up with me, for caring about my well-being, and for occasionally mustering the bravery to ask about my research. To all of my teachers throughout the years—Kathy McCulloch, Mark Hill, Peter Scully, and so many others, thank you for inspiring me. To my most recent mentor, Haiyuan, thank you for entrusting me with a great deal of responsibility in the early years of your lab, and for providing advice when I needed it, but still allowing me the freedom to determine my own course of study and explore my passions. To my committee—Chris, David, and Olivier— thank you for you for your genuine interest in my work and your feedback over the years. To several generations of labmates—thank you for being my daily buffer against the slog of graduate school—for the laughs, distractions, and taunts during March Madness. To the amazing undergraduate researchers I’ve worked with—Ryan, Philip, Mark, and Aaron— thank you for your enthusiasm, willingness to learn, and major contributions to much of the v work in this dissertation. To the old guard—Jishnu, Amanda, Tommy, and Robert—thanks for being there from the beginning and for helping to establish a productive and supportive research environment. Jishnu, thanks for showing me the ropes, for the most interesting arguments, and for sharing your encyclopedic knowledge of the literature. Tommy, thanks for your tireless efforts to make FissionNet a success, and for teaching me a thing or two about the wet lab in the process. To the new kids—Juan, Siwei, Antoine, and Charles—good luck. Juan, thank you for arriving at just the right time to remind me why I love what I do, for all the white-boarding, and for helping to create some really cool stuff. Thanks for the late- night code jams and after-work beers, for provocative discussions of philosophy, and for one awkward bro hug. And to Sarai—thanks for, well, everything. For all the little stuff—slipping butter between two halves of a grab-and-go muffin on a Monday morning, counting cats on summer evening walks, and leaving me little notes to find around the house. Thank you for being there, for smiling and laughing, for spontaneity and routine. And thank you for going with me on this first of many adventures—we made it. vi CONTRIBUTIONS I would also like to acknowledge the work of others that has gone into each of the chapters presented in this dissertation. Due to the collaborative nature of biological research, I have had the pleasure to work with many gifted scientists, several of whom are co-authors on the publications presented here.

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.

  • A Semantic Standard for Describing the Location of Nucleotide and Protein Feature Annotation Jerven T
    Bolleman et al. Journal of Biomedical Semantics (2016) 7:39 DOI 10.1186/s13326-016-0067-z RESEARCH Open Access FALDO: a semantic standard for describing the location of nucleotide and protein feature annotation Jerven T. Bolleman1*, Christopher J. Mungall2, Francesco Strozzi3, Joachim Baran4, Michel Dumontier5, Raoul J. P. Bonnal6, Robert Buels7, Robert Hoehndorf8, Takatomo Fujisawa9, Toshiaki Katayama10 and Peter J. A. Cock11 Abstract Background: Nucleotide and protein sequence feature annotations are essential to understand biology on the genomic, transcriptomic, and proteomic level. Using Semantic Web technologies to query biological annotations, there was no standard that described this potentially complex location information as subject-predicate-object triples. Description: We have developed an ontology, the Feature Annotation Location Description Ontology (FALDO), to describe the positions of annotated features on linear and circular sequences. FALDO can be used to describe nucleotide features in sequence records, protein annotations, and glycan binding sites, among other features in coordinate systems of the aforementioned “omics” areas. Using the same data format to represent sequence positions that are independent of file formats allows us to integrate sequence data from multiple sources and data types. The genome browser JBrowse is used to demonstrate accessing multiple SPARQL endpoints to display genomic feature annotations, as well as protein annotations from UniProt mapped to genomic locations. Conclusions: Our ontology allows

  • A Flexible Microfluidic System for Single-Cell Transcriptome Profiling
    www.nature.com/scientificreports OPEN A fexible microfuidic system for single‑cell transcriptome profling elucidates phased transcriptional regulators of cell cycle Karen Davey1,7, Daniel Wong2,7, Filip Konopacki2, Eugene Kwa1, Tony Ly3, Heike Fiegler2 & Christopher R. Sibley 1,4,5,6* Single cell transcriptome profling has emerged as a breakthrough technology for the high‑resolution understanding of complex cellular systems. Here we report a fexible, cost‑efective and user‑ friendly droplet‑based microfuidics system, called the Nadia Instrument, that can allow 3′ mRNA capture of ~ 50,000 single cells or individual nuclei in a single run. The precise pressure‑based system demonstrates highly reproducible droplet size, low doublet rates and high mRNA capture efciencies that compare favorably in the feld. Moreover, when combined with the Nadia Innovate, the system can be transformed into an adaptable setup that enables use of diferent bufers and barcoded bead confgurations to facilitate diverse applications. Finally, by 3′ mRNA profling asynchronous human and mouse cells at diferent phases of the cell cycle, we demonstrate the system’s ability to readily distinguish distinct cell populations and infer underlying transcriptional regulatory networks. Notably this provided supportive evidence for multiple transcription factors that had little or no known link to the cell cycle (e.g. DRAP1, ZKSCAN1 and CEBPZ). In summary, the Nadia platform represents a promising and fexible technology for future transcriptomic studies, and other related applications, at cell resolution. Single cell transcriptome profling has recently emerged as a breakthrough technology for understanding how cellular heterogeneity contributes to complex biological systems. Indeed, cultured cells, microorganisms, biopsies, blood and other tissues can be rapidly profled for quantifcation of gene expression at cell resolution.

  • A Combined RAD-Seq and WGS Approach Reveals the Genomic
    www.nature.com/scientificreports OPEN A combined RAD‑Seq and WGS approach reveals the genomic basis of yellow color variation in bumble bee Bombus terrestris Sarthok Rasique Rahman1,2, Jonathan Cnaani3, Lisa N. Kinch4, Nick V. Grishin4 & Heather M. Hines1,5* Bumble bees exhibit exceptional diversity in their segmental body coloration largely as a result of mimicry. In this study we sought to discover genes involved in this variation through studying a lab‑generated mutant in bumble bee Bombus terrestris, in which the typical black coloration of the pleuron, scutellum, and frst metasomal tergite is replaced by yellow, a color variant also found in sister lineages to B. terrestris. Utilizing a combination of RAD‑Seq and whole‑genome re‑sequencing, we localized the color‑generating variant to a single SNP in the protein‑coding sequence of transcription factor cut. This mutation generates an amino acid change that modifes the conformation of a coiled‑coil structure outside DNA‑binding domains. We found that all sequenced Hymenoptera, including sister lineages, possess the non‑mutant allele, indicating diferent mechanisms are involved in the same color transition in nature. Cut is important for multiple facets of development, yet this mutation generated no noticeable external phenotypic efects outside of setal characteristics. Reproductive capacity was reduced, however, as queens were less likely to mate and produce female ofspring, exhibiting behavior similar to that of workers. Our research implicates a novel developmental player in pigmentation, and potentially caste, thus contributing to a better understanding of the evolution of diversity in both of these processes. Understanding the genetic architecture underlying phenotypic diversifcation has been a long-standing goal of evolutionary biology.

    Review Article Next-Generation Sequencing for Cancer Diagnostics: a Practical Perspective Cliff Meldrum,1,4† Maria A Doyle,2† *Richard W Tothill3 1Molecular Pathology, Hunter Area Pathology Service, Newcastle, NSW 2310; 2Bioinformatics and 3Next-generation DNA Sequencing Facility Research Department and 4Pathology Department, Peter MacCallum Cancer Centre, Melbourne, Vic. 3002, Australia. †These authors contributed equally to this manuscript. *For correspondence: Dr Richard Tothill, [email protected] Abstract Next-generation sequencing (NGS) is arguably one of the most significant technological advances in the biological sciences of the last 30 years. The second generation sequencing platforms have advanced rapidly to the point that several genomes can now be sequenced simultaneously in a single instrument run in under two weeks. Targeted DNA enrichment methods allow even higher genome throughput at a reduced cost per sample. Medical research has embraced the technology and the cancer field is at the forefront of these efforts given the genetic aspects of the disease. World-wide efforts to catalogue mutations in multiple cancer types are underway and this is likely to lead to new discoveries that will be translated to new diagnostic, prognostic and therapeutic targets. NGS is now maturing to the point where it is being considered by many laboratories for routine diagnostic use. The sensitivity, speed and reduced cost per sample make it a highly attractive platform compared to other sequencing modalities. Moreover, as we identify more genetic determinants of cancer there is a greater need to adopt multi-gene assays that can quickly and reliably sequence complete genes from individual patient samples. Whilst widespread and routine use of whole genome sequencing is likely to be a few years away, there are immediate opportunities to implement NGS for clinical use.
