LEF-1 regulated the survival of colon cell lines. (A) LEF-1-ΔL or LEF-1-FL was expressed stably in SW480 and HT29 cells, and cell death was examined by annexin V-FITC/PI staining. The numbers in images are the percentages of annexin V positive cells. (B) The caspase-3 activity was assessed in the cell lines that expressed LEF-1-ΔL or LEF-1-FL. *P < 0.05.
