Figure 5

A and B show the drug sensitivity of ECA109 and KYSE510 after transfection with siRNA-GADD45α. ECA109 and KYSE510 cells in NC-siRNA group were more sensitive to DDP than that in two GADD45α-siRNA groups at 24 h, 48 h and 72 h with DDP treatment. Moreover, the percent of survival cells was measured by MTT value. C and D, show that the percent of survival cells at 24 h, 48 h and 72 h with DDP treatment were degraded in two GADD45α-siRNA groups compared to NC-siRNA groups.
