The tumor cells infected with RCASBP-Bcl-xL invaded through Matrigel about 20-fold more efficiently than those infected with RCASBP-dnE-cad, and none of the uninfected parental cells or the cells infected with RCASBP-GFP had the ability to invade (Figure 8B). The gene discussed is BCL2L1; the disease is neoplasm.
