Database Description

RNA interference (RNAi) has become a powerful tool for genetic screening in Drosophila. At the Drosophila RNAi Screening Center (DRSC), we are using a library of over 21,000 dsRNAs targeting known and predicted genes in Drosophila. This library is available for the use of visiting scientists wishing to perform full-genome RNAi screens. The data generated from these screens is collected in the DRSC database (http://flyRNAi.org/cgi-bin/RNAi_screens.pl) in a flexible format for the convenience of the scientist and for archiving data. The long-term goal of this database is to provide annotations for as many of the uncharacterized genes in Drosophila as possible. Data from published screens are available to the public through a highly configurable interface that allows detailed examination of the data and provides access to a number of other databases and bioinformatics tools.

Screening at the DRSC Visiting scientists typically perform their screens in duplicate - screening against two full-genome sets. Raw data from duplicate genome sets are collected along with phenotype and "hit" information. The scientists have password-protected accounts which give them access to data entry interfaces and direct links to their personal data, both published and unpublished. The logged in user also has access to some tools for viewing data a plate at a time, direct links to the bioinformatic tools (listed below), and functions for directly querying the quality control (QC) information for the source plates.

Website Overview The public database begins with a page listing all published screens that have been done at the DRSC. From there, the experimental data for each assay may be viewed in a configurable table. Where possible, links to the published papers and supplementary data are also provided. Also on the starting page are links to various informatic tools, a gene lookup function which provides extensive amplicon data, and a list of completed, but not yet published, screens.
