(A) Hypothetical illustration of cancer cell surviving fraction according to dose and oxygen partial pressure, as modeled using RadioGx. Solid curves are modeled using Equation (3) (Methods). The computed AUC values are 2.41, 2.71, 2.97 for normoxia (160 mmHg), hypoxic condition with 10 mmHg, and hypoxic condition with 5 mmHg, respectively. (B) Changes in AUC by tissue type (with minimum of 15 cell lines within RadioGx) under normoxic (160 mmHg) or hypoxic (5 mmHg) conditions, ordered according to median AUC under normoxia. (C) The difference in ranks are shown between the strength of univariate association of each gene with AUC under normoxic (160 mmHg) vs. hypoxic (5 mm Hg) conditions across cancer cell lines within RadioGx.
