Review

A recent study by used a genome-wide RNAi screen in Drosophila cells to identify 238 candidate regulators of the Wnt-signaling pathway, most of which had not been previously connected to Wnt signaling. Supporting in vivo studies are in progress. The fact that such an impressive number of potential modulators had eluded detection in genetic screens underscores the potential of applying new, high-throughput approaches to old problems.
