Detecting microRNA binding and siRNA off-target effects from expression data

Sylamer is a method for detecting microRNA target and small interfering RNA off-target signals in 3 ' untranslated regions from a ranked gene list, sorted from upregulated to downregulated, after a microRNA perturbation or RNA interference experiment. The output is a landscape plot that tracks occurrence biases using hypergeometric P-values for all words across the gene ranking. We demonstrated the utility, speed and accuracy of this approach on several datasets.
