Fig. 5From: Combination of isoliquiritigenin and tumor necrosis factor-related apoptosis-inducing ligand induces apoptosis in colon cancer HT29 cellsSchematic model. The combination of isoliquiritigenin and TRAIL markedly induces apoptosis in HT29 cells. Isoliquiritigenin up-regulates DR5 expression, which is considered to enhance TRAIL action. Enhanced TRAIL signaling results in apoptosis through the activation of caspase-8/10, 9 and 3. Caspase-8/10 can activate caspase-3 via caspase-9, which acts downstream of mitochondriaBack to article page
