'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
