miR2Disease: a manually curated database for microRNA deregulation in human disease

TLDR

miR2Disease is a manually curated database that provides a comprehensive resource of microRNA deregulation across human diseases. The database stores detailed microRNA–disease entries—including IDs, disease names, expression patterns, detection methods, verified targets, and literature references—and allows researchers to submit new relationships for review before inclusion. The current release documents 1,939 curated microRNA–disease relationships involving 299 miRNAs and 94 diseases, with about one‑seventh indicating pathogenic roles, and offers a free, user‑friendly interface for retrieval and submission.

Abstract

'miR2Disease', a manually curated database, aims at providing a comprehensive resource of microRNA deregulation in various human diseases. The current version of miR2Disease documents 1939 curated relationships between 299 human microRNAs and 94 human diseases by reviewing more than 600 published papers. Around one-seventh of the microRNA–disease relationships represent the pathogenic roles of deregulated microRNA in human disease. Each entry in the miR2Disease contains detailed information on a microRNA–disease relationship, including a microRNA ID, the disease name, a brief description of the microRNA–disease relationship, an expression pattern of the microRNA, the detection method for microRNA expression, experimentally verified target gene(s) of the microRNA and a literature reference. miR2Disease provides a user-friendly interface for a convenient retrieval of each entry by microRNA ID, disease name, or target gene. In addition, miR2Disease offers a submission page that allows researchers to submit established microRNA–disease relationships that are not documented. Once approved by the submission review committee, the submitted records will be included in the database. miR2Disease is freely available at http://www.miR2Disease.org.
