Figure 5From: Expression of delta-catenin is associated with progression of human astrocytoma Invasion assay of cells transfected with δ-catenin and siRNA. δ-Catenin transfection promoted cell invasion in U251 cells, while siRNA knockdown of δ-catenin had an inhibitory effect. The numbers of cells invading onto the lower surface of the filter was significantly different (p < 0.05). Columns, mean; bars, SD.Back to article page
