Abstract: | MicroRNAs (miRNAs) are small 22 nucleotide RNA molecules that directly bind to the 3' Untranslated regions of protein-coding messenger RNAs. This binding event represses the target transcript rendering it unsuitable for protein production and causing its degradation. Many miRNAs have been found and a large-number of them have already been implicated in human disease and development. We have developed a number of computational approaches for predicting the target transcripts of miRNAs. One method (miRanda) is purely computational and uses a simple dynamic programming algorithm and a statistical model to identify significant binding sites. Our second approach (Sylamer) is an algorithm for scanning genome sequences for 7mer words and testing gene-expression data to identify gene sets which are significantly enriched or depleted in such 7mer words using Hypergeometric Statistics. This combined computational/experimental approach has worked extremely well for identifying candidate miRNA targets in B and T blood cells, developing Zebrafish embryos and in mouse mutants with deafness.
