CyTRANSFINDER is a new Cytoscape 3.x plugin that supports the reconstruction of small signal transduction pathways among groups of genes. Signal Transduction Pathways are molecular circuits that model how cells receive, process, and respond to information from the environment providing snapshots of the overall cell dynamics. Most of the attempts to reconstruct signal transaction pathways are limited to single regulator networks including gene/protein. However, networks involving a single type of regulator and neglecting post-transcriptional regulation mediated by miRNAs interacting with different transcription factors may not fully reveal the complex regulatory mechanisms of a cell.

We have developed CyTRANSFINDER, to enable users to infer three-component signal transduction pathways with the presence of miRNAs, TFs and genes based on user defined regulatory patterns. CyTRANSFINDER has been designed to support exploratory analysis, it therefore does not rely on expression data.
