PubChem provides a user-friendly deposition system to facilitate data exchanges and submissions. The PubChem BioAssay database currently consists of bioactivity information generated by high-throughput screenings and medicinal chemistry studies. PubChem's bioassay data are integrated into the NCBI Entrez information retrieval system, thus making PubChem data searchable and accessible by Entrez queries. This mechanism makes it easier for depositors to validate information prior to submission, and enables them to adequately describe projects for internal requirements. Epub 2014 Jan 17. Multiple preview/update cycles are often required to identify and fix problems before committing the data for publication in PubChem. Due to the inherent complexity of bioassay data, support of the deposition system is a demanding task. Funding for open access charge: US government.

The PubChem Deposition Gateway supports chemical and assay data submission through a web-based system at http://pubchem.ncbi.nlm.nih.gov/deposit/. In addition, a cell viability assay and a caspase 3/7 assay were deposited by the Laboratory of Environmental Genomics at the Carolina Center for Computational toxicology, University of North Carolina at Chapel Hill (http://comptox.unc.edu/); and a USP14 inhibitor assay was deposited by the Finley and King Labs at the Harvard Medical School (9). As a result, RNAi screenings in PubChem are automatically linked to small molecule assays if the biologically responsive genes from an RNAi screening and the protein targets of small molecules are involved in the same pathway. The order of the compound Ids is the same as the data files. Two new components, e.g. Some of these tools have been described in detail previously (2). To ease the submission of substance records for general biologists, substance records can now be uploaded as a standard spreadsheet file, including CSV, or files supported by Excel or OpenOffice. A non-trivial task for the system is to validate the submitted data content and provide flexible interface for editing the submissions. By default, PubChem shows and distributes the information from the most recent version of a bioassay record through its web services and FTP sites; however, earlier versions of the record can be retrieved through the BioAssay Summary web service upon user request. In addition, the user interface of the deposition system is further tailored to better support the submission and the representation of features unique to RNAi data. PubChem continues to host screening data generated by the NIH Molecular Libraries and Imaging Program (MLP) (http://commonfund.nih.gov/molecularlibraries/). This new web interface can be accessed by following the download icon on a BioAssay Entrez DocSum page (Figure 2) to export records identifies based on a user's search criteria. One can also use the ‘Cited Publication’ menu on the Limits page to search assays associated with a selected journal. bioactivity outcome, score and active concentration attribute, allows one to rank and evaluate the hits identified in the screening experiment. A ‘Preview’ facility is provided for both substance and assay depositions. A spreadsheet file (CSV, or files supported by Excel and OpenOffice programs) can now be used to fully define a bioassay description. -, Wang Y.L., Xiao J.W., Suzek T.O., Zhang J., Wang J.Y., Zhou Z.G., Han L.Y., Karapetyan K., Dracheva S., Shoemaker B.A., et al.
