"240 genes that were upregulated in the Wnt-activated samples compared with the Wnt-inhibited samples were identified (L.G., W. Chen, T. Brodigan, M. Krause and D.M.E., unpublished). Among these potential Wnt pathway targets, were the GATA factor genes
egl-18 and
elt-6 [average fold change of 2.1 (P=0.06) and 2.8 (P=0.01), respectively]. We confirmed the microarray result by qRT-PCR on animals overexpressing stabilized β-catenin BAR-1 at the L2/L3 molt (supplementary material Fig. S2)."
