Forodesine/dGuo and ara-G sensitivity in pediatric leukemia. (A) LC50 values for forodesine/dGuo for T-ALL, BCP-ALL, and AML leukemia samples. When no LC50 was reached, a value of 10μM was assigned. (B) LC50 values for ara-G for T-ALL, BCP-ALL, and AML leukemias. When no LC50 was reached a value of 50μM was assigned. Median LC50 values are indicated by gray horizontal lines. Significance levels are indicated by asterisks: *P < .05; **P < .01; ***P < .001.
