Effect of TSI on viability of HTL-9 cells, MCF-7 cells, and GES-1 cells assayed by MTT

Values were expressed as the average of triple determination with ±SD. ^* P<0.05, ^** P<0.01 (values of test groups compared with that of non-treatment). TSI could dramatically reduce viability of HTL-9 cells and MCF-7 cells as TSI concentration increased, whereas, the viability of normal GES-1 cells was not significantly affected when the TSI concentration was lower than 100 μg/ml
