Hi We published an R package early in 2009 which may help you: http://bioinformatics.iah.ac.uk/software/corna Wu X, Watson M: CORNA: testing gene lists for regulation by microRNAs. Bioinformatics 2009, 25(6):832-833. CORNA can download data directly from miRBase targets (now called Microcosm targets) but this hasn't been updated in a while. CORNA can, though, take any generic list of miR:gene target pairs and use that instead.

The only package containing database data might be "RmiR.Hs.miRNA" (dependency of RmiR). The version might be indicated in the source code (check the SVN repository for that bioconductor package), otherwise the author should be contacted.
