Abstract

Objective: Non-small cell lung cancer (NSCLC) is still a solid tumor with high malignancy and poor prognosis. Vascular endothelial growth factor receptor 3 (FLT4, VEGFR3) is overexpressed in NSCLC cells, making it a potential target for NSCLC treatment. In this study, we aimed to explore the anti-cancer effects of dauricine on NSCLC cells and its mechanism targeting FLT4.

Methods: We found that dauricine inhibited the growth of NCI-H1299 cells by blocking the cycle in the G2/M phase through flow cytometry analysis. In addition, dauricine also inhibited the migration of NCI-H1299 cells by wound healing assay and transwell migration assay. More importantly, our empirical analysis found the anti-cancer effect of dauricine on NCI-H1299 cells and the protein level of FLT4 had a distinctly positive correlation, and this effect was weakened after FLT4 knockdown.

Results: It is suggested that dauricine suppressed the growth and migration of NCI-H1299 cells by targeting FLT4. Furthermore, dauricine inhibited FLT4 downstream pathways, such as PTEN/AKT/mTOR and Ras/MEK1/2/ERK1/2, thereby regulating cell migration-related molecule MMP3 and cell cycle-related molecules (CDK1, pCDK1-T161, and cyclin B1).

Conclusion: Dauricine may be a promising FLT4 inhibitor for the treatment of NSCLC.
