Figure 3From: Identification of genes regulated by Wnt/β-catenin pathway and involved in apoptosis via microarray analysis Apoptosis induced by depletion of β-catenin. HeLaT-β-catenin-RNAi cells were grown on coverslips and treated without (a) or with (b) DOX. After 3 days, cells were analyzed for apoptosis with the TUNEL assay. Dark-blue staining of nuclei indicates apoptosis.Back to article page
