Non‑small cell lung cancer (NSCLC) is the most common pathological subtype of lung cancer and is associated with low 5‑year overall survival rates. Therefore, novel and effective chemotherapeutic drugs are urgently required for improving the survival outcomes of patients with lung cancer. Cyclovirobuxine D (CVB‑D) is a natural steroidal alkaloid, used for the treatment of cardiovascular diseases in Traditional Chinese Medicine. Several studies have also demonstrated the antitumor effects of CVB‑D. Therefore, in the present study, the therapeutic effects of CVB‑D in lung cancer and the underlying mechanisms were investigated using the in vivo xenograft model of NSCLCin nude mice and in vitro experiments with the NSCLC cell  \nCorrespondence to: Dr Pengzhou Kong, Key Laboratory of Cellular Physiology of The Ministry of Education and Department of Pathology, Shanxi Medical University, 56 South Xinjian Road, Yingze, Taiyuan, Shanxi 030001, P.R.

Bioinformatics analyses of RNA‑sequencing data, and cell‑based functional assays demonstrated that CVB‑D treat‑ ment significantly inhibited in vitro and in vivo NSCLC cell proliferation, survival, invasion, migration, angiogenesis, epithelial‑to‑mesenchymal transition and G2/M phase cell cycle. CVB‑D exerted its antitumor effects by inhibiting the KIF11‑CDK1‑CDC25C‑cyclinB1 G2/M phase transition regulatory oncogenic network and the NF‑κB/JNK signaling pathway. CVB‑D treatment significantly reduced the sizesand weights and malignancy of xenograft NSCLC tumors in the nude mice. In conclusion, the present study demonstrated that CVB‑D inhibited the growth and progression of NSCLC cells by inhibiting the KIF11‑CDK1‑CDC25C‑CyclinB1 G2/M phase transition regulatory network and the NF‑κB/JNK signaling pathway. Therefore, CVB‑D is a promising drug for the treatment of NSCLC patients.  \nIntroduction  \nLung cancer is the leading cause of cancer incidence, morbidity and mortality worldwide (1) .
