1 Kurarinone promotes TRAIL-induced apoptosis by inhibiting NF-kappaB-dependent cFLIP expression in HeLa cells. kurarinone TNF superfamily member 10 Homo sapiens
2 This study was designed to investigate the effects of the prenylated flavonoid kurarinone on TNF-related apoptosis inducing ligand (TRAIL)-induced apoptosis and its underlying mechanism. kurarinone TNF superfamily member 10 Homo sapiens
3 This study was designed to investigate the effects of the prenylated flavonoid kurarinone on TNF-related apoptosis inducing ligand (TRAIL)-induced apoptosis and its underlying mechanism. kurarinone TNF superfamily member 10 Homo sapiens
4 A low dose of kurarinone had no significant effect on apoptosis, but this compound markedly promoted tumor cell death through elevation of Bid cleavage, cytochrome c release release and caspase activation in HeLa cells treated with TRAIL. kurarinone TNF superfamily member 10 Homo sapiens
5 On the other hand, kurarinone significantly inhibited TRAIL-induced IKK activation, IkappaB degradation and nuclear translocation of NF-kappaB, as well as effectively suppressed cellular FLICE-inhibitory protein long form (cFLIPL) expression. kurarinone TNF superfamily member 10 Homo sapiens
6 The synergistic effects of kurarinone on TRAIL-induced apoptosis were mimicked when kurarinone was replaced by the NF-kappaB inhibitor withaferin A or following siRNA-mediated knockdown of cFLIPL. kurarinone TNF superfamily member 10 Homo sapiens
7 The synergistic effects of kurarinone on TRAIL-induced apoptosis were mimicked when kurarinone was replaced by the NF-kappaB inhibitor withaferin A or following siRNA-mediated knockdown of cFLIPL. kurarinone TNF superfamily member 10 Homo sapiens
8 Moreover, cFLIP overexpression effectively antagonized kurarinone-mediated TRAIL sensitization. kurarinone TNF superfamily member 10 Homo sapiens
9 These data suggest that kurarinone sensitizes TRAIL-induced tumor cell apoptosis via suppression of NF-kappaB-dependent cFLIP expression, indicating that this compound can be used as an anti-tumor agent in combination with TRAIL. kurarinone TNF superfamily member 10 Homo sapiens
10 These data suggest that kurarinone sensitizes TRAIL-induced tumor cell apoptosis via suppression of NF-kappaB-dependent cFLIP expression, indicating that this compound can be used as an anti-tumor agent in combination with TRAIL. kurarinone TNF superfamily member 10 Homo sapiens
