Purpose Erianin plays a certain role in the treatment of tumors, inflammation, diabetes nephropathy, retinopathy and other diseases. However, the impact and mechanism of Erianin on osteosarcoma(OS) are still unclear. This article aims to investigate the mechanism of action of Erianin in OS. Methods Animal experiments were conducted using nude mice to investigate the in vivo effects of Erianin on OS. Investigations into the in vitro effects of Erianin on OS were conducted through cell experiments utilizing MG-63 and U-2 OS human OS cell lines. Firstly, use the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay to detect cell viability and calculate IC50. Using colony-formation assay to detect the inhibitory effect of Erianin on cell proliferation. Use wound healing assay and cell migration assay to detect the effect of Erianin on the migration of OS cells. Use flow cytometry to detect cell apoptosis. Observe the effect of Erianin on the survival of OS cells under a microscope using Acridine Orange/Propidium Iodide(AO/PI) staining. Use glutathione detection kit to detect the effect of Erianin on the ferroptosis signaling pathway in OS cells. Verify protein expression using western blot. Results In vitro, Erianin inhibits proliferation and migration of OS cells by regulating cyclin and apoptotic proteins, leading to ferroptosis of OS cells; In vivo, Erianin can also inhibits tumor growth and cause ferroptosis of OS. Conclusion The findings of Erianin's induction of apoptosis and ferroptosis, as well as its inhibition of proliferation and migration of OS cells, point to it as a potential therapeutic agent for OS that warrants further investigation.
