Effect of LACE on the growth of ANDO-2 in nude mice. a) There was not differences between the different control groups, while LACE induced tumor growth inhibition reached to about 60%. The Y-axis represents long tumor diameter and the X-axis represents time (day) after ANDO-2 cell injection. Each data point represents the mean ± SD of three independent experiments. b) Effect of LACE in survival time. The percentage survival was calculated as: % survival = number of survival mice in the test group/number of mice in the group. Data are representative of three independent experiments.
