PG - 1743-1754 LID - 10.1007/s10637-020-00979-2 [doi] AB - Naringenin (NG) is a natural antioxidant flavonoid which is isolated from citrus fruits, and has been reported to inhibit colon cancer proliferation. However, the effects of NG treatment on glioma remain to be elucidated. The present study aimed to explore the effects of NG on glioma in vitro and in vivo. Also, the interactions between NG and APO2 ligand (APO2L; also known as tumor necrosis factor-related apoptosis-inducing ligand) were investigated in glioma. A synergistic effect of NG and APO2L combination on apoptotic induction was observed, though glioma cells were insensitive to APO2L alone. After NG treatment, glioma cells resumed the sensitivity to APO2L and cell apoptosis was induced via the activation of caspases, elevation of decoy receptors 4 and 5 (DR4 and DR5) and induction of p53. Coadministration of NG and APO2L decreased levels of anti-apoptotic B cell lymphoma 2 (Bcl-2) family members Bcl-2 and Bcl-extra large (Bcl-xL), while increased levels of proapoptotic factors Bcl-2-associated agonist of cell death (Bad) and Bcl-2 antagonist/killer 1 (Bak). Furthermore, an in vivo mouse xenograft model demonstrated that NG and APO2L cotreatment markedly suppressed glioma growth by activating apoptosis in tumor tissues when compared with NG or APO2L monotherapy. The present study provides a novel therapeutic strategy for glioma by potentiating APO2L-induced apoptosis via the combination with NG in glioma tumor cells.
