A useful step for understanding the function of microRNAs (miRNA) or siRNAs is the detection of their effects on genome-wide expression profiles. Typically, approaches look for enrichment of words in the 3 UTR sequences of the most deregulated genes. A number of tools are available for this purpose, but they require either in-depth computational knowledge, filtered 3 UTR sequences for the genome of interest, or a set of genes acquired through an arbitrary expression cutoff. To this end, we have

It simply requires the user to submit a sorted list of genes from an expression experiment. SylArray utilizes curated sets of 3 UTRs to attach sequences to these genes and then applies the Sylamer algorithm for detection of miRNA or siRNA signatures in those sequences. An intuitive system for visualization and interpretation of the small RNA signatures is included. Availability: SylArray is written in Perl-CGI, Perl and Java and also uses the R statistical package.
