Abstract:
Lung cancer has garnered significant global attention as a result of its escalating rates of mortality and morbidity, necessitating focused interventions to mitigate its impact. The primary aim of this work was to investigate the anticancer activity of juglone in A549 cells, specifically focusing on its role in mediating ferroptosis. We conducted an investigation involving a range of cytotoxic and morphological assays, such as cell viability assay, fluorescence microscopic analysis, flow cytometry, and ROS assay. The findings demonstrated that the cytotoxicity of juglone was around 18.5 μM. Furthermore, the chemical was found to promote apoptotic activity as observed through fluorescent microscopic inspection and morphological analysis. In addition, the levels of ROS, MDA, GSH, ferrous iron, and colony formation study demonstrated a significant increase, indicating a correlation with the occurrence of ferroptosis. Hence, juglone exhibits promise as a prospective therapeutic drug in the treatment of lung cancer. Therefore, we put forward that the utilization of ferroptosis as a therapeutic approach for lung cancer may yield significant efficacy and warrants further investigation in subsequent studies.
