Glioma is a common malignant tumor in nervous system, but the treatment efficacy is still unsatisfactory. Licochalcone A (Lic-A) is a kind of flavonoid isolated from glycyrrhiza and shows anti-tumor effect. This study aimed to investigate anti-tumor efficacy of Lic-A on glioma using both in vivo and in vitro models. The in vitro results showed that Lic-A inhibited the growth, migration, and invasion of glioma cells in a dose-dependent way. Lic-A induced mitochondrial dysfunction by regulating Bcl-2 family and induced reactive oxygen species (ROS), while ROS inhibition enhanced the migration and invasion of glioma cells. Finally, animal experiments confirmed that Lic-A inhibited the growth of glioma in vivo. In conclusion, our results suggest that Lic-A can inhibit the migration and invasion of glioma cells while inducing apoptosis of glioma cells. The mechanism may be related to the activation of ATM/ATR pathway and the induction of oxidative stress.
