The identification of new therapeutic uses for compounds via computational or experimental approaches, which is widely known as drug repurposing, has the potential to develop novel therapies with pre-existing medicines, thereby reducing the time and costs associated with drug development. Today, several data-driven methodologies have been developed leading to databases that facilitate drug repurposing initiatives. However, no approach has systematically compared drug transcriptional profiles to those from a wide spectrum of human diseases or molecular pathways. Here, we present the Drug Repurposing Encyclopedia (DRE, https://www.drugrep.org), an interactive web server covering over 198M significant drug-signature associations across 20 organisms to allow users to carry out drug-repositioning analyses. DRE consists of 12 modules covering real-time drug-repurposing for user-provided transcriptional signatures; gene set enrichment analysis (GSEA) for all available drug transcriptomics profiles; as well as similarity analyses for provided gene sets across all database signatures. Collectively, DRE provides a one-stop comprehensive solution to help scientists interested in drug-repurposing studies.

Matching journals

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
