Figure 1. Drug resistance profiling of ten esophageal cancer cell lines. (A) Experimental scheme. (B–E) IC₅₀ values of the four indicated chemotherapeutics. for ten esophageal cancer cell lines. The cell survival rates were calculated as percentages relative to the mock treatment and plotted against lg μg/ml of drug. (F) The IC₅₀ values to those of the most sensitive cell cine (Kyse450) are presented in the table.
