摘要：

Sinapine (SI) is a naturally occurring product with biological properties, but its activity against non-small cell lung cancer (NSCLC) remains unclear. This research examined the anti-tumour effects of SI in NSCLC cells and the underlying mechanisms of any effects. SI induced ferroptosis, a novel form of cell death, by increasing intracellular ferrous iron, lipid peroxidation, and reactive oxygen species (ROS) in NSCLC cells. SI treatment resulted in transferrin and transferrin receptor upregulation, and inhibition of transferrin or the transferrin receptor reduced the ferroptosis caused by SI. SI treatment also resulted in a p-53 dependent downregulation of SLC7A11. Finally, we evaluated the effects of SI in vivo and it was found that SI also successfully inhibited the growth of NSCLC in vivo. In summary, our data demonstrated that SI triggered ferroptosis in NSCLC cells and may be a promising therapeutic agent for this condition.
