PubChem BioAssay

PubChem BioAssay (1 - 4) is an open access database hosted by the National Center for Biotechnology Information (NCBI), National Library of Medicine (NLM), National Institutes of Health (NIH). It started in 2004 serving as a public repository for information generated from chemogenomic, medicinal chemistry and functional genomics research The PubChem BioAssay resource continues to be explored by the community, as shown by the growing number of citations for the PubChem resource. Interesting and insightful work using PubChem BioAssay is more likely to be found by searching in PubMed or PMC with the keywords PubChem BioAssay or otherwise simply with PubChem in general

work presents a review of the HTS data content in the PubChem BioAssay database and the progress of data deposition to stimulate knowledge discovery and data sharing. It also provides a description of the database's data standard and basic utilities facilitating information access and use for new users PubChem BioAssay currently contains over 1700 biochemical and cell-based bioassay screens, containing nearly 60 million biological activity outcomes for several thousand different protein and gene targets. These test results provide biological annotations for more than 750000 unique small molecule chemical structures and tens of thousands of siRNA probes. While the majority of the archived. The PubChem BioAssay database currently contains 500 000 bioassay records, a total of over 130 000 000 bioactivity summary results and 740 000 000 data points. These test results represent rich biological properties for 120 chemical probes, 1 600 000 small molecules and 60 000 RNAi reagents

PubChem BioAssay closes the gap between molecular and chemical biology research by presenting and linking up information of both chemical and RNAi tools in one system supporting the study of gene function and biological pathways. The majority of small molecule screening data in PubChem are associated with protein targets, while RNAi screening data links each tested reagent to a gene. PubChem provides multiple mechanisms for cross-referencing protein and gene targets from bioactivity dat PubChem BioAssay Consists of deposited bioactivity data and descriptions of bioactivity assays used to screen the chemical substances contained in the PubChem Substance database, including descriptions of the conditions and the readouts (bioactivity levels) specific to the screening procedure

PubChem Upload tool enables users to submit data to the PubChem Substance and PubChem BioAssay databases. Types of data accepted include chemical structures, experimental biological activity results, annotations, siRNA and more PubChem is an open chemistry database at the National Institutes of Health (NIH). Open means that you can put your scientific data in PubChem and that others may use it.

The BioAssay tools were developed when PubChem was much smaller. At PubChem's current size, the tools do not scale sufficiently to handle most analysis tasks. Consequently, many users download data for use in their assay analysis workflows instead of using the tools. Deprecating these BioAssay Tools will free up resources allowing PubChem to develop new and better approaches to accessing.

A PubChem BioAssay is a fairly complex and sometimes very large entity with a great deal of data, so there are routes both to entire assay records and various component data readouts, etc., so that you can more easily get just the data that you're interested in. From AID Assay Description . An assay is composed of two general parts: the description of the assay as a whole, including. In light of this problem, the PubChem BioAssay database, an open-access repository providing the bioactivity information of compounds that were already tested on a biological target, is now a recommended source for data set construction. Nevertheless, there exist several issues with the use of such data that need to be properly addressed. In this article, an overview of benchmarking data. The PubChem bioassay collection, reporting the activity of compounds in multiple assays, allows us to study polypharmacological behavior in the PubChem collection via cross-assay analysis. In this paper, we developed a network representation of the assay collection and then applied a bipartite mapping between this network and various biological networks (i.e., PPI, pathway) as well as.

The NCBI insights blog has another wonderful post about PubChem. This week, the post focuses on using the Bioassay database and how it can help identify chemical reagents and drugs. Tobin Magle, P In PubChem, depositors may assign multiple result types to an assay. However, if an assay is deposited as a 'confirmatory' assay (defined as an assay where a range of SID concentrations have been tested, with a view to determining a measurement of potency), then one of the result types must be marked up as an 'Active Concentration' (AC) result type.

PubChem BioAssay: 2014 update Nucleic Acids Research

Background: PubChem is an open archive consisting of a set of three primary public databases (BioAssay, Compound, and Substance). It contains information on a broad range of chemical entities, including small molecules, lipids, carbohydrates, and (chemically modified) amino acid and nucleic acid sequences (including siRNA and miRNA). Currently (as of Nov. 2015), PubChem contains more than 150 million depositor-provided chemical substance descriptions, 60 million unique chemical structures. Based on the premise that some of the molecular actors of ADRs involve interactions that are detectable in large, and increasingly public, compound screening campaigns, we generated logistic regression models that correlate postmarketing ADRs with screening data from the PubChem BioAssay database. These models analyze ADRs at the level of organ systems, using the system organ classes (SOCs). Of the 19 SOCs under consideration, nine were found to be significantly correlated with preclinical.

A bioassay is an analytical method to determine concentration or potency of a substance by its effect on living cells or tissues. Bioassays are quantitative biological assays used to estimate the potency of agents by observing their effects on living animals (in vivo) or tissue/cell culture systems (in vitro).. A bioassay experiment can either be qualitative or quantitative, direct or indirect The BioAssay Ontology (BAO) describes chemical biology screening assays and their results including high-throughput screening (HTS) data for the purpose of categorizing assays and data analysis. BAO is an extensible, knowledge-based, highly expressive (currently SHOIQ(D)) description of biological assays making use of descriptive logic based features of the Web Ontology Language (OWL). BAO.
