Guggulsterone-induced apoptosis in cholangiocarcinoma cells through ROS/JNK signaling pathway.

Cholangiocarcinoma (CCA), the most common biliary tract malignancy, is arising from the bile duct epithelium with the global significantly increased morbidity and mortality. Here, we showed the effect of guggulsterone, a steroid found in the resin of the guggul plant, on human HuCC-T1 and RBE CCA cells. Exposure to various concentrations of guggulsterone for multiple action time resulted in significant apoptosis in the CCA cells via activating both extrinsic and intrinsic pathways.
