Combination treatment with cisplatin and TAK1 inhibitor increases survival even with advanced tumors. (A) Scheme depicting experimental design for end-stage survival analysis of control, cisplatin-treated, and combination-treated KF mice. IT, intratracheal. (B) Kaplan-Meier curve showing effect of cisplatin (CPPD; 3.5 mg/kg) or cisplatin plus 5Z-7-oxozeaenol (7 mg/kg) treatment on survival of tumor-bearing KF mice (n = 4 vehicle and cisplatin, n = 6 combination). P value calculated using log-rank (Mantel–Cox) test (**, P = 0.0011). See also Fig. S5.
