Andrographolide Enhances TRAIL-Induced Apoptosis via p53-Mediated Death Receptors Up-Regulation and Suppression of the NF-кB Pathway in Bladder Cancer Cells.

ABSTRACT: Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is an effective chemotherapeutic agent that specifically impairs cancer cells while sparing normal cells; however, some cancer cells develop resistance to TRAIL. Here, we identified Andrographolide, a diterpenoid lactone derived from a traditional herbal medicine Andrographis paniculata, as an ideal sensitizer for TRAIL to overcome bladder cancer. Our results showed that combination treatment of Andro and TRAIL retarded growth, attenuated proliferation, decreased colony formation, inhibited migration and promoted caspases-mediated apoptosis in T24 cells. Additionally, the sensitization by Andro is achieved through up-regulation of death receptors (DR4 and DR5) of TRAIL in a p53-dependent manner. Crucially, Andro
