    Open access to sequence data is a cornerstone of biology and biodiversity research, but has created tension under the United Nations Convention on Biological Diversity (CBD). Policy decisions could compromise research and development, unless a practical multilateral solution is implemented.This workwas funded by the German Federal Ministry of Education and Research (BMBF) WiLDSI 031B0862 (A.H.S., J.O., and J.F.) and Horizon Europe EVA-GLOBAL 871029 (A.H.S.).

    GA4GH: International policies and standards for data sharing across genomic research and healthcare.

    Get PDF
    The Global Alliance for Genomics and Health (GA4GH) aims to accelerate biomedical advances by enabling the responsible sharing of clinical and genomic data through both harmonized data aggregation and federated approaches. The decreasing cost of genomic sequencing (along with other genome-wide molecular assays) and increasing evidence of its clinical utility will soon drive the generation of sequence data from tens of millions of humans, with increasing levels of diversity. In this perspective, we present the GA4GH strategies for addressing the major challenges of this data revolution. We describe the GA4GH organization, which is fueled by the development efforts of eight Work Streams and informed by the needs of 24 Driver Projects and other key stakeholders. We present the GA4GH suite of secure, interoperable technical standards and policy frameworks and review the current status of standards, their relevance to key domains of research and clinical care, and future plans of GA4GH. Broad international participation in building, adopting, and deploying GA4GH standards and frameworks will catalyze an unprecedented effort in data sharing that will be critical to advancing genomic medicine and ensuring that all populations can access its benefits

    Identifying the intracellular survival strategies of chlamydiae

    Chlamydia is the most commonly diagnosed sexually transmitted infection in the UK. The etiological agent, Chlamydia trachomatis (Ct), is an obligate intracellular bacterium that resides within an intracellular niche, termed the inclusion, following entry into host cells. Chlamydiae avoid lysosomal destruction by diverging away from the normal endocytic trafficking pathway. Ct expresses a type-III secretion system (T3SS) that enables the translocation of Ct effector proteins into the host cytoplasm and these proteins are essential for virulence. Relatively little is understood regarding the pathogenesis of chlamydiae and the mechanisms they use to manipulate host defences because, until recently, they have been intractable to genetic manipulation. In this thesis, we describe both a targeted and random screening approach for the identification of Ct T3SS effector proteins in the yeast Saccharomyces cerevisiae. We firstly use an in silico prediction program to identify Ct proteins that are likely to be secreted by the bacterium’s T3SS. The predicted proteins were then screened for their ability to disrupt membrane trafficking using an established pathogen effector protein screening in yeast (PEPSY) screening method. In parallel, we also generated a Ct genomic library in order to PEPSY screen the entire chlamydial genome for proteins involved in disrupting membrane trafficking. We identified two chlamydial deubiquitinases (DUB), ChlaDUB1 and ChlaDUB2, which disrupt intracellular membrane trafficking in a yeast model system. These chlamydial DUBs were expressed in mammalian cells and their effects on endosomal compartments, EGFR internalisation and degradation, IκBα levels and global ubiquitin levels were examined. Our findings suggest that ChlaDUB1 and ChlaDUB2 are likely to demonstrate broad substrate specificity towards host substrates and this research paves the way for future research to investigate the role of chlamydial DUBs in the manipulation of host membrane trafficking during infection

    The data use ontology to streamline responsible access to human biomedical datasets

    Human biomedical datasets that are critical for research and clinical studies to benefit human health also often contain sensitive or potentially identifying information of individual participants. Thus, care must be taken when they are processed and made available to comply with ethical and regulatory frameworks and informed consent data conditions. To enable and streamline data access for these biomedical datasets, the Global Alliance for Genomics and Health (GA4GH) Data Use and Researcher Identities (DURI) work stream developed and approved the Data Use Ontology (DUO) standard. DUO is a hierarchical vocabulary of human and machine-readable data use terms that consistently and unambiguously represents a dataset's allowable data uses. DUO has been implemented by major international stakeholders such as the Broad and Sanger Institutes and is currently used in annotation of over 200,000 datasets worldwide. Using DUO in data management and access facilitates researchers' discovery and access of relevant datasets. DUO annotations increase the FAIRness of datasets and support data linkages using common data use profiles when integrating the data for secondary analyses. DUO is implemented in the Web Ontology Language (OWL) and, to increase community awareness and engagement, hosted in an open, centralized GitHub repository. DUO, together with the GA4GH Passport standard, offers a new, efficient, and streamlined data authorization and access framework that has enabled increased sharing of biomedical datasets worldwide.G.K., M.A.F., H.P., J.D.S., and M.C. were funded by EMBL-EBI Core Funds and Wellcome Trust GA4GH award number 201535/Z/16/Z.
