OBJECTIVE Platinum compounds such as cisplatin and carboplatin are frequently used as the first-line chemotherapy for the treatment of the head and neck squamous cell carcinoma(HNSCC).In the present study,we investigated whether garcinol,apolyisoprenylated benzophenone can chemosensitize HNSCC to *** The effect of garcinol and cisplatin on HNSCC was assessed by MTT,Western blotting,real time PCR,FACS,immunohistochemistry,DNA binding assay and xenograft mouse *** We found that garcinol inhibited the viability of a panel of diverse HNSCC cell lines,enhanced the apoptotic effect of cisplatin,suppressed constitutive as well as cisplatin-induced NF-κB activation,and downregulated the expression of various oncogenic gene products(cyclin D1,Bcl-2,survivin and VEGF).In vivo study showed that administration of garcinol alone(0.5 mg·kg-1,ip five times/week)significantly suppressed the growth of the tumor,and this effect was further increased by *** the markers of proliferation index(Ki-67)and microvessel density(CD31)were downregulated in tumor tissues by the combination of cisplatin and *** pharmacokinetic results of garcinol indicated that good systemic exposure was achievable after ip administration of garcinol at 0.5and 2mg·kg-1 with mean peak concentration(cmax)of 1825.4 and 6635.7nmol·L-1 in the mouse serum,*** Overall,our results suggest that garcinol can indeed potentiate the effects of cisplatin by negative regulation of various inflammatory and proliferative biomarkers.
