Abstract
Ferroptosis is caused by accumulation of iron-dependent lipid peroxidation, which is characterized by reduction in cell volume and increase in mitochondrial membrane density. Studies have shown that ferroptosis contributes to the development and progression of numerous major diseases, including hepatocellular carcinoma (HCC). As a unique biomedical resource, Traditional Chinese Medicine (TCM) has been widely used in the treatment of HCC. In this present study, Scutellaria barbata was used to treat HCC cells in vitro, and the results revealed that S. barbata suppressed HCC cell growth through inducing ferroptosis. Next, the exploration of the molecular mechanism on how S. barbata induced ferroptosis in HCC cells suggested that S. barbata may induce ferroptosis by promoting iron perioxidation and lipid ROS metabolism. Finally, S. barbata also inhibited HCC tumorigenicity in vivo by inducing ferroptosis of HCC cells. These results provided theoretical basis for explaining the mechanism of TCM treatment for HCC and offered therapeutic opportunities for HCC patients.
