Abstract | Background: The incidence and mortality of non-small cell lung cancer (NSCLC) are extremely high. Previous research has confirmed that the signal transducer and activator of the transcription 3 (STAT3) protein critically participate in the tumorigenesis of NSCLC. Mebendazole (MBZ) has exerts a larger number of pharmacological activities and has anticancer effects in lung cancer, but its mechanism of action remains unclear. This study thus aimed to clarify the impacts of MBZ on NSCLC cell. Methods: Cell proliferation, migration, and apoptosis were investigated via cell counting kit 8 (CCK-8) assay, Transwell assay, colony formation assay, wound-healing assay, and flow cytometry. Reactive oxygen species (ROS) were detected with a multifunctional microplate reader. Markers of cell migration and apoptosis were detected with Western blotting. The transcriptional activity of STAT3 was detected via luciferase assay. ROS scavenger N-acetylcysteine (NAC) was used to determine the effect of MBZ on NSCLC via ROS-regulated STAT3 inactivation and apoptosis. A xenograft model was constructed Results: The findings demonstrated that MBZ inhibited NSCLC cell proliferation and migration while promoting apoptosis through triggering ROS generation. In addition, the Janus kinase 2 (JAK2)-STAT3 signaling pathway was abrogated with the treatment of MBZ. NAC could distinctly weaken MBZ-induced apoptosis and STAT3 inactivation. Moreover, MBZ inhibited the tumor growth of NSCLC Conclusions: In summary, MBZ inhibited NSCLC cell viability and migration by inducing cell apoptosis via the ROS-JAK2-STAT3 signaling pathway. These data provide a theoretical basis for the use of MBZ in treating NSCLC. |
