The effect of Methylstat and GDC-0941 combination in vivo. (A) NOD-SCID mice bearing MB436 xenografts were treated with vehicle (n = 13) and Methylstat (30 mg/kg; n = 12) by intraperitoneal injection twice a week, GDC-0941 (100 mg/kg; n = 15) by oral gavage daily, or both drugs (n = 6) for 2 wk. Tumor volumes were measured twice a week. (B) Western blot analysis of representative tumors from each experimental group in A. MW, molecular weight. (C) NOD-SCID mice bearing MB436 (TetOn-shKDM4B) xenografts were fed with diets of doxycycline or treated with GDC-0941 (100 mg/kg) by oral gavage daily or in combination as indicted for 1 mo. Tumor volumes were measured twice a week. Vehicle (n = 9), doxycycline (n = 9), GDC-0941 (n = 10), combination (n = 10). (D) Western blot analysis of representative tumors from each experimental group in C. (E) NOD-SCID mice bearing PTEN-deficient PDX#41 were treated with vehicle (n = 6) and ML324 (60 mg/kg; n = 7) by intraperitoneal injection daily, GDC-0941 (100 mg/kg; n = 7) by oral gavage daily, or both drugs (n = 6) for 2 wk. NOD-SCID mice bearing PTEN wild-type PDX#EL12-58 were treated with vehicle (n = 6), ML324 (60 mg/kg; n = 6), GDC-0941 (100 mg/kg; n = 6), or both drugs (n = 6) for 2 wk. Tumor volumes were measured twice a week. (F) Western blot analysis of representative tumors from each experimental group in E. See also Fig. S5. Data are presented as mean ± SEM. P values were determined by two-tailed unpaired Student’s t test; ns P > 0.05, * P ≤ 0.05, ** P ≤ 0.01, *** P ≤ 0.001, **** P ≤ 0.0001.
