I am searching for a tool to test whether an interaction. Micrornas mirnas are key mediators of posttranscriptional gene expression silencing. Subsequently, a mirna mrna regulatory network depicting interactions between. Intarna enables the prediction of rnarna interactions. But, this does not measure the direct and physical interaction between a mirna and a specific mrna.
Which tool to be used for building mirnamrna interaction. It has been designed to predict mrna target sites for given noncoding rnas ncrnas like eukaryotic micrornas mirnas or bacterial small rnas srnas, but it can also be used to predict other types of rnarna interactions. A database for exploring micrornamrna interaction maps from argonaute clipseq and degradomeseq data. The aim of this study was to identify mrna targets of dysregulated mirnas through the integrated analysis of mirna and mrna expression profiling in men with normal versus impaired.
