摘要: Oridonin is a diterpenoid isolated from the Rabdosia rubescens and has multiple biological effects, such as anti-inflammation anti-tumor activities. In present study, we revealed that sensitizing effect of oridonin on tumor necrosis factor-related apoptosis-inducing ligand (TRAIL)-induced apoptosis in several cancer cells, but not normal cells. enhanced death-signaling inducing complexes (DISC) formation DR5 glycosylation without affecting expression downstream intracellular apoptosis-related proteins. upregulated peptidyl O-glycosyltransferase GALNT14 dose- time-dependent manner. Knockdown by siRNA Endo H treatment reduced oridonin-induced glycosylation. Furthermore, with inhibitor (benzyl-α-GalNAc) blocked plus TRAIL-induced apoptosis. Collectively, our results suggest contributes to apoptotic cell death
