Abstract
Background/Aim: Non-small cell lung cancer is known for its rapid growth and immune evasion, demanding effective therapies targeting both tumor cells and the microenvironment. Magnolol has shown promising anti-tumor effects in various cancers. Materials and Methods: CL1-5-F4-bearing mice were divided into control, 40 mg/kg, and 60 mg/kg magnolol groups, once tumors reached 100 mm3. Tumor growth and body weight were monitored biweekly, and after 13 days, mice were euthanized for tumor and organ collection for subsequent staining. Histopathology and serum biochemistry assessed organ toxicity. Results: Magnolol dose-dependently suppressed NSCLC progression, with no pathology alterations observed in normal organs. Magnolol-induced apoptosis and cell cycle arrest, evidenced by increased cleaved caspase-3 and decreased cyclin D1/CDK4 levels. It also down-regulated VEGF, FOXP3, and IDO-1 in tumors, implicating tumor microenvironment modulation. Conclusion: Magnolol exhibits significant antitumor effects in NSCLC by inducing apoptosis, inhibiting proliferation, and modulating the tumor microenvironment. These results support further investigation of magnolol as a therapeutic adjuvant to enhance NSCLC treatment outcomes.
