Effects of p120-catenin isoforms in human colon cancer cells. (A) Transient transfection increased the levels of p120-catenin isoforms 1A, 3A and 4A in SW480 cells. Effects of p120-catenin isoforms on (B) cell viability, at the 96-h time-point, p120-catenin isoform 4A was significantly different from the vector control (p<0.05). (C) BrdU incorporation, and (D) cell invasion were as detailed in Figure 6, legend. Slopes of the p120-isoform treatments were each significantly different from the vector control, p<0.05.
