ZCWPW1 Is Recruited to Recombination Hotspots by PRDM9
RESEARCH ARTICLE ZCWPW1 is recruited to recombination hotspots by PRDM9 and is essential for meiotic double strand break repair Daniel Wells1,2†*, Emmanuelle Bitoun1,2†*, Daniela Moralli1, Gang Zhang1, Anjali Hinch1, Julia Jankowska1, Peter Donnelly1,2, Catherine Green1, Simon R Myers1,2* 1The Wellcome Centre for Human Genetics, Roosevelt Drive, University of Oxford, Oxford, United Kingdom; 2Department of Statistics, University of Oxford, Oxford, United Kingdom Abstract During meiosis, homologous chromosomes pair and recombine, enabling balanced segregation and generating genetic diversity. In many vertebrates, double-strand breaks (DSBs) initiate recombination within hotspots where PRDM9 binds, and deposits H3K4me3 and H3K36me3. However, no protein(s) recognising this unique combination of histone marks have been identified. We identified Zcwpw1, containing H3K4me3 and H3K36me3 recognition domains, as having highly correlated expression with Prdm9. Here, we show that ZCWPW1 has co-evolved with PRDM9 and, in human cells, is strongly and specifically recruited to PRDM9 binding sites, with higher affinity than sites possessing H3K4me3 alone. Surprisingly, ZCWPW1 also recognises CpG dinucleotides. Male Zcwpw1 knockout mice show completely normal DSB positioning, but persistent DMC1 foci, severe DSB repair and synapsis defects, and downstream sterility. Our findings suggest ZCWPW1 recognition of PRDM9-bound sites at DSB hotspots is critical for *For correspondence: synapsis, and hence fertility.

Nancy Goroff Interim Dean of the Graduate School ii Abstract of the Dissertation Sequential Monte Carlo Methods for Inference and Prediction of Latent Time-series by Iñigo Urteaga Doctor of Philosophy in Electrical Engineering Stony Brook University 2016 In the era of information-sensing mobile devices, the Internet- of-Things and Big Data, research on advanced methods for extracting information from data has become extremely critical. One important task in this area of work is the analysis of time-varying phenomena, observed sequentially in time. This endeavor is relevant in many applications, where the goal is to infer the dynamics of events of interest described by the data, as soon as new data-samples are acquired. -

Network Cross-Validation by Edge Sampling
Biometrika (2020), 107,2,pp. 257–276 doi: 10.1093/biomet/asaa006 Printed in Great Britain Advance Access publication 4 April 2020 Network cross-validation by edge sampling By TIANXI LI Department of Statistics, University of Virginia, B005 Halsey Hall, 148 Amphitheater Way, Charlottesville, Virginia 22904, U.S.A. [email protected] Downloaded from https://academic.oup.com/biomet/article/107/2/257/5816043 by guest on 01 July 2021 ELIZAVETA LEVINA AND JI ZHU Department of Statistics, University of Michigan, 459 West Hall, 1085 South University Avenue, Ann Arbor, Michigan 48105, U.S.A. [email protected] [email protected] Summary While many statistical models and methods are now available for network analysis, resampling of network data remains a challenging problem. Cross-validation is a useful general tool for model selection and parameter tuning, but it is not directly applicable to networks since splitting network nodes into groups requires deleting edges and destroys some of the network structure. In this paper we propose a new network resampling strategy, based on splitting node pairs rather than nodes, that is applicable to cross-validation for a wide range of network model selection tasks. We provide theoretical justification for our method in a general setting and examples of how the method can be used in specific network model selection and parameter tuning tasks. Numerical results on simulated networks and on a statisticians’ citation network show that the proposed cross-validation approach works well for model selection. Some key words: Cross-validation; Model selection; Parameter tuning; Random network. 1. Introduction Statistical methods for analysing networks have received a great deal of attention because of their wide-ranging applications in areas such as sociology, physics, biology and the medical sciences. -

Final Report (PDF)
Bioinformatics, Genetics and Stochastic Computation: Bridging the Gap July 1-6 2007 Closing report The meeting that took place at BIRS, Banff, on July 1-6 2007, gathered 33 people from America (Canada and USA), Europe, Japan and Australia. It was quite successful, thanks to the superb organisation of the Center and the friendly help of the staff, and all invited participants showed up for the meeting. The talks were uniformly well-attended by an overwhelming number of the participants who stayed the whole week, with two exceptions only. There was no mountain accident or bear encounter to deplore, and the organisers were not aware of any complaint from the participants, during or after the meeting, but instead gathered many thanks and requests for a follow-up meeting. Several collaborations were initiated during the meeting as well. OBJECTIVES On the one hand, there is an explosion of complex statistical models appearing in genetics and bioin- formatics. These typically highly structured systems are unfortunately very difficult to fit. On the other hand, there has been recently significant advances on MC methods but most of these methods are unknown to the applied community and/or formulated in ways that are too theoretical for direct application. By providing scientists with improved inferential methods it would allow them to consider richer models, which are more realistic than those dictated by computational constraints. The exchanges between the applied and methodological communities remain surprisingly limited. We believe that this workshop would be an ideal place to (1) Gather people from different research communities and foster links between these communities (applied, methodological and theoretical). -

University of Oxford Mathematics and Physical Sciences Division Salary
University of Oxford Post Ref: AM001004/5/6/7/8/ Mathematics and Physical Sciences Division LN/A 1719 2 Postdoctoral Research Assistants (PDRA). Academic-related Research Staff Grade 1A: Salary £19,460 - £29,128 Two postdoctoral research positions of three years duration in Bioinformatics funded by BBSRC are available for working in the Bioinformatics Group headed by Jotun Hein. This project will focus on models of sequence evolution that includes a process of insertion-deletion of nucleotides and their implementation. Furthermore, developed methods will be applied to complete genomes as they are determined in coming years. The work will include algorithm development, statistical modelling, software development and large scale comparative analysis of genomes. The research will take place at The Oxford Centre for Gene Function. Earliest starting date is 1st November 2004. The Research Project: Practical Statistical Alignment. Although bioinformatics perceived is a new discipline, certain parts have a long history and could be viewed as classical bioinformatics. For example, application of string comparison algorithms to sequence alignment has a history spanning the last three decades. The principle of choosing solutions by minimizing the amount of evolution is also called parsimony and has been widespread in phylogenetic analysis even if there is no alignment problem. Over the last two decades the parsimony method of phylogenetic reconstruction has been severely criticized and has lost terrain to methods based on stochastic modelling of nucleotides, codons or amino acids. The present project will develop, implement and simultaneously apply methods including insertion-deletions of nucleotides/amino acids to give a full model of sequence evolution.
