Juniperus chinensis extract induces apoptosis via reaction oxygen species (ROS) generation in human pancreatic cancer cell lines

Pancreatic cancer is among the most difficult-to-treat tumors. More than half of patients with this cancer have very few symptoms at the early stages, allowing the development of distant metastases and resistance to cancer treatment. In this study, we found that Juniperus chinensis extract (JCX) decreased the cell viability and migration activity of PANC-1 and SNU-213 pancreatic cancer cells in a dose-dependent manner. JCX increased caspase3 activation and generation of reactive oxygen species (ROS). Nacetylcysteine treatment blocked JCX-induced ROS generation and the negative effects on pancreatic cancer cell viability. In addition, JCX down-regulated the levels of phospho-focal adhesion kinase (p-FAK) and phospho-extracellular signal-regulated kinase (p-ERK). Together, these results indicate that JCX induces apoptosis in human pancreatic cancer cell lines through ROS production, downregulating FAK/ERK signaling and activating caspase-3. We propose that JCX-derived compounds represent candidates for the development of alternative medicines for the treatment of pancreatic cancer. KCI Citation Count: 0
