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.

D011990	Receptors, Transferrin	Membrane glycoproteins found in high concentrations on iron-utilizing cells. They specifically bind iron-bearing transferrin, are endocytosed with its ligand and then returned to the cell surface where transferrin without its iron is released.	Transferrin Receptors,Transferrin Receptor,Receptor, Transferrin
D002289	Carcinoma, Non-Small-Cell Lung	A heterogeneous aggregate of at least three distinct histological types of lung cancer, including SQUAMOUS CELL CARCINOMA; ADENOCARCINOMA; and LARGE CELL CARCINOMA. They are dealt with collectively because of their shared treatment strategy.

D014168	Transferrin	An iron-binding beta1-globulin that is synthesized in the LIVER and secreted into the blood. It plays a central role in the transport of IRON throughout the circulation. A variety of transferrin isoforms exist in humans, including some that are considered markers for specific disease states.
