1 Resistance to TRAIL is associated with defects in ceramide signaling that can be overcome by exogenous C6-ceramide without requiring down-regulation of cellular FLICE inhibitory protein. Ceramides TNF superfamily member 10 Homo sapiens
2 Mass spectrometry was used to compare ceramide content in untreated and TRAIL-treated cells. Ceramides TNF superfamily member 10 Homo sapiens
3 Overall levels of ceramide were comparable in the cell lines but TRAIL-sensitive SW480 cells contained a higher percentage of C(16)-, and C(18)-ceramide and lower C(24)-ceramides than TRAIL-resistant SW620 cells. Ceramides TNF superfamily member 10 Homo sapiens
4 Overall levels of ceramide were comparable in the cell lines but TRAIL-sensitive SW480 cells contained a higher percentage of C(16)-, and C(18)-ceramide and lower C(24)-ceramides than TRAIL-resistant SW620 cells. Ceramides TNF superfamily member 10 Homo sapiens

6 Upon TRAIL treatment, ceramide (primarily C(16)-ceramide) increased in SW480 but not SW620 cells. Ceramides TNF superfamily member 10 Homo sapiens
7 Exposure to TRAIL prior to ceramide was required to induce apoptosis, suggesting that ceramide plays a role in enhancing or amplifying TRAIL-mediated signaling. Ceramides TNF superfamily member 10 Homo sapiens
8 Exposure to TRAIL prior to ceramide was required to induce apoptosis, suggesting that ceramide plays a role in enhancing or amplifying TRAIL-mediated signaling. Ceramides TNF superfamily member 10 Homo sapiens
9 Our results suggest that ceramide plays a role in promoting TRAIL-mediated apoptosis and that TRAIL-resistant cancers may benefit from combination therapy with ceramide or agents that enhance ceramide accumulation. Ceramides TNF superfamily member 10 Homo sapiens
10 Our results suggest that ceramide plays a role in promoting TRAIL-mediated apoptosis and that TRAIL-resistant cancers may benefit from combination therapy with ceramide or agents that enhance ceramide accumulation. Ceramides TNF superfamily member 10 Homo sapiens
