Developed by the Laboratory of Human Retrovirology and Immunoinformatics (LHRI) at the Frederick National Laboratory for Cancer Research, DAVID was designed to solve this specific bottleneck. It functions as an integrated biological knowledgebase and a powerful analytical engine.
At its core, DAVID performs Functional Enrichment Analysis. It asks a simple question: Are the genes in my list appearing in specific biological pathways more often than would be expected by random chance?
Key Features That Define DAVID:
An agronomist studies drought tolerance in Arabidopsis. After exposing plants to dehydration stress, they submit the resulting gene list to DAVID. The platform returns "response to abscisic acid," "stomatal closure," and "osmolyte biosynthesis" as top clusters, confirming the physiological data and revealing novel regulatory candidates.
A virologist performs an siRNA screen and identifies 50 host factors required for viral replication. DAVID clusters these into "Nuclear transport" and "Ubiquitin ligase complex." The researcher now knows to test drugs inhibiting Ubiquitination. david bioinformatics resources
How does DAVID compare to other functional enrichment resources?
The utility of DAVID spans virtually every domain of life science research. Developed by the Laboratory of Human Retrovirology and
DAVID is not a single tool but a suite of integrated resources. Understanding these components is key to leveraging its power.
