RNA localization is an important mechanism for generating cellular diversity and polarity in the early embryo. In Xenopus, the correct localization of the RNA encoding the T-box transcription factor VegT is essential for the correct spatial organization and identity of endoderm and mesoderm. Although localization signals in the 3' UTR have been identified(More)
The Cell Line Ontology (CLO) is a community-based ontology in the domain of biological cell lines with a focus on permanent cell lines from culture collections. Upper ontology structures that frame the skeleton of CLO include the Basic Formal Ontology and Relation Ontology. Cell lines contained in CLO are associated with terms from other ontologies such as(More)
Members of the transforming growth factor-beta (TGF-beta) superfamily play various roles during development in both vertebrates and invertebrates. Two isoforms, TGF-beta2 and -beta5, have been isolated from Xenopus laevis. We describe here the localization of TGF-beta5 mRNA in early embryos of X. laevis, assessed by whole-mount in situ hybridization. The(More)
BACKGROUND High-throughput screening (HTS) is one of the main strategies to identify novel entry points for the development of small molecule chemical probes and drugs and is now commonly accessible to public sector research. Large amounts of data generated in HTS campaigns are submitted to public repositories such as PubChem, which is growing at an(More)
The lack of established standards to describe and annotate biological assays and screening outcomes in the domain of drug and chemical probe discovery is a severe limitation to utilize public and proprietary drug screening data to their maximum potential. We have created the BioAssay Ontology (BAO) project (http://bioassayontology.org) to develop common(More)
Huge amounts of high-throughput screening (HTS) data for probe and drug development projects are being generated in the pharmaceutical industry and more recently in the public sector. The resulting experimental datasets are increasingly being disseminated via publically accessible repositories. However, existing repositories lack sufficient metadata to(More)
BACKGROUND Cell lines have been widely used in biomedical research. The community-based Cell Line Ontology (CLO) is a member of the OBO Foundry library that covers the domain of cell lines. Since its publication two years ago, significant updates have been made, including new groups joining the CLO consortium, new cell line cells, upper level alignment with(More)
MOTIVATION Novel tools need to be developed to help scientists analyze large amounts of available screening data with the goal to identify entry points for the development of novel chemical probes and drugs. As the largest class of drug targets, G protein-coupled receptors (GPCRs) remain of particular interest and are pursued by numerous academic and(More)
BAOSearch is a semantic web application for querying, browsing and downloading biological screening data relevant for drug discovery. We developed a BioAssay Ontology (BAO) in order to formalize the domain of biological screening and annotated large sets of data to make complex and diverse life science data accessible to researchers via simple queries. Our(More)
