Somebody knows which is the most complete and updated database for looking miRNA gene-targets (validated targets)?
I have tried miRWalk but some results makes me think that is incomplete or outdated. I have hundreds of miRNAs to assign function so I need that the data looks like GSEA files on miRwalk.
You can try the starBase (http://starbase.sysu.edu.cn/) database, it has been updated to decode miRNA-mRNA, miRNA-lncRNA, miRNA-sncRNA, miRNA-circRNA, miRNA-pseudogene, protein-lncRNA inteactions from CLIP-Seq (HITS-CLIP, PAR-CLIP, iCLIP, CLASH) and degradome sequencing data.
starBase also decipher Pan-Cancer Analysis Networks of lncRNAs, miRNAs, ceRNAs and RNA-binding proteins (RBPs) by mining clinical and expression profiles of 14 cancer types (>6000 samples) from The Cancer Genome Atlas (TCGA) Data Portal.
You are looking for miRNA-mRNA pairs validated using experimental data? I expect that set to be rather limited.
Yes, it is, but target prediction is even worst and limited I think so.
