1 Since caspase-8 activation is associated with the activation of death receptors, such as Fas, tumor necrosis factor (TNF), or TNF-related apoptosis-inducing ligand (TRAIL) receptors, studies were conducted to determine the exact death receptor(s) and ligand(s) involved in mediating tocotrienol-induced caspase-8 activation and apoptosis. Tocotrienols caspase 8 Mus musculus
2 These data demonstrate that tocotrienol-induced caspase-8 activation and apoptosis is not mediated through death receptor activation in malignant (+)SA mammary epithelial cells. Tocotrienols caspase 8 Mus musculus
3 In summary, these findings demonstrate that tocotrienol-induced caspase-8 activation and apoptosis in malignant (+)SA mammary epithelial cells is not mediated through the activation of death receptors, but appears to result from the suppression of the PI3K/PDK/Akt mitogenic signalling pathway, and subsequent reduction in intracellular FLIP expression. Tocotrienols caspase 8 Mus musculus
