Abstract BACKGROUND: Bone morphogenetic protein 2 (BMP-2) is a member of the TGF-β superfamily that is closely correlated with many malignancies, particularly lung cancer. However, the effects of silenced BMP-2 on lung cancer cell proliferation and migration are not clear. METHODS: Using quantitative real-time RT-PCR, BMP-2 mRNA expression was detected in 61 non-small cell lung cancer (NSCLC) samples. Survival curves were generated using follow-up data. Relationships between clinical or pathological characteristics and prognosis were analyzed. Cell viability assays and transwell migration assays were used to evaluate the effects of BMP-2 silencing on cell proliferation and migration of A549 and H460 cells. RESULTS: BMP-2 mRNA expression was higher in NSCLC tissues compared to matched adjacent normal tissues (P<0.01). High BMP-2 expression levels were significantly associated with the occurrence of lymph node metastases and tumor stage (P<0.05). There were significant differences in survival curves between groups with metastatic lymph nodes and non-metastatic lymph nodes, as well as between groups with low BMP-2 expression and groups with high BMP-2 expression. In addition, we observed decreased proliferation and migration rates of the NSCLC-derived cell lines A549 and H460 that were transfected with siBMP-2 (P<0.05). CONCLUSION: BMP-2 mRNA is overexpressed in NSCLC samples and is a risk factor for survival in patients with NSCLC. BMP-2 silencing can significantly inhibit A549 and H460 cell proliferation and migration.
