Provides for the first time hundreds of thousands of high quality manually curated experimentally validated miRNA:gene interactions, enhanced with detailed meta-data. With DIANA-TarBase v7.0 you can easily identify positive or negative experimental results, the utilized experimental methodology, experimental conditions including cell/tissue type and treatment. The new interface provides also advanced information ranging from the binding site location, as identified experimentally as well as in silico, to the primer sequences used for cloning experiments.
