Endometrial Cancer (EC) is the most 
frequently diagnosed gynecological malignancy and 
the fourth most common cancer diagnosis overall 
among women. As with many other forms of 
cancer, it has been shown that certain miRNAs are 
differentially expressed in EC and these miRNAs 
are believed to play important roles as regulators of 
processes involved in the development of the 
disease. With the rapidly growing number of studies 
of miRNA expression in EC, there is a need to 
organize the data, combine the findings from 
experimental studies of EC with information from 
various miRNA databases, and make the integrated 
information easily accessible for the EC research 
community. The miREC database is an organized 
collection of data and information about miRNAs 
shown to be differentially expressed in EC. The 
database can be used to map connections between 
miRNAs and their target genes in order to identify 
specific miRNAs that are potentially important for  
the development of EC.
