Nootkatone inhibits the progression of glioblastoma by activating the ATF4-CHOP-CHAC1 pathway.

ABSTRACT: Glioblastoma multiforme (GBM) represents a primary brain tumor that is widely prevalent, and clinical drugs available for its treatment exhibit varying degrees of resistance. Nootkatone (NKT) is a functional sesquiterpene sourced from traditional Chinese medicine --Alpinia Oxyphylla Miq and has been reported to have a diverse range of pharmacological properties. However, it remains unknown whether there are effects of NKT on GBM. In this study, we found that NKT inhibited the growth of GBM cells in a dose-dependent manner in vitro. Subsequently, we observed that NKT suppressed the migration and arrested cell cycle at G2/M phase of GBM cells. Furthermore, NKT induced the death of GBM cells accompanied by an increase in reactive oxygen species (ROS) production. Mechanistically, we found that
