Inhibition of the phosphatidylinositol 3-kinase/mammalian target of rapamycin pathway in NCI-H929 cells enhances their sensitivity to chemotherapeutic drugs. (A and B) Cell death rate was significantly lower in NCI-H929/ABCG2+ cells compared with NCI-H929 cells treated with (A) As2O3 or (B) Bort. (C and D) LY or RA treatment significantly increased cell death rate in regular and ABCG2-overexpressing NCI-H929 cells following treatment with various doses of (C) As2O3 or (D) Bort. **P<0.01. ABC, ATP binding cassette; ABCG2, ABC subfamily G member 2; As2O3, arsenic trioxide; Bort, bortezomib; LY, LY294002; RA, rapamycin.
