ABSTRACT
BACKGROUND:
Non-Small Cell Lung Cancer (NSCLC), a prevalent type of lung cancer, has a poor prognosis and contributes to a high mortality rate. Agrimonolide, which belongs to the Rosaceae family, possesses various biomedical activities. This study aimed to explore the efficacy and mechanism of agrimonolide in NSCLC.METHODS:
The viability, proliferation, and tumor-forming ability of A549 cells were detected using the Cell Counting Kit-8 assay (CCK-8) assay, EdU staining, and colony formation assay. The cell cycle was detected using flow cytometry. Cell migration and invasion were detected using wound healing and transwell assays. Western blot was used to detect Epithelial-Mesenchymal Transition (EMT)-, ferroptosis-, and mechanistic targets of rapamycin (mTOR) signaling pathway-related proteins. Lipid peroxidation was detected using the thiobarbituric acid reactive substances (TBARS) assay kit, while lipid Reactive Oxygen Species (ROS) was detected using a BODIPY 581/591 C11 kit. The level of Fe2+ was detected using corresponding assay kits.RESULTS:
In this study, agrimonolide with varying concentrations (10, 20, and 40 µM] could inhibit the proliferation, induce cycle arrest, suppress metastasis, induce ferroptosis, and block the mTOR signaling pathway in NSCLC cells. To further reveal the mechanism of agrimonolide associated with the mTOR signaling pathway in NSCLC, mTOR agonist MHY1485 (10 µM) was used to pre-treat A549 cells, and functional experiments were conducted again. It was found that the protective effects of AM on NSCLC cells were all partially abolished by MHY1485 pre-treatment.CONCLUSION:
Agrimonolide inhibited the malignant progression of NSCLC and induced ferroptosis by blocking the mTOR signaling pathway, thus indicating the potential of agrimonolide as a prospective candidate for treating NSCLC.
