Abstract

Hispolon has been demonstrated to possess analgesic, anti-inflammatory and anticancer activities. However, whether hispolon prevents the invasion of breast carcinoma cells and the underlying mechanisms of its action remain unknown. In the present study, various assays, including a matrigel‑based Transwell invasion assay and electrophoretic mobility shift assay, were used to investigate the anti‑invasion effect of hispolon and explore its mechanism of action. The results revealed that hispolon inhibited the 12‑O‑tetradecanoylphorbol‑13‑acetate (TPA)‑induced migration and invasion of MDA‑MB‑231 human breast cancer cells at non‑toxic concentrations. Hispolon also prevented the TPA‑induced secretion of matrix metalloproteinase‑9 (MMP‑9) and reduced its expression at the transcriptional and translational levels. Furthermore, the phosphorylation of IκBα was reduced by hispolon, which resulted in the suppression of nuclear factor‑κB (NF‑κB), and p65 phosphorylation and nuclear translocation. An electrophoretic mobility shift assay demonstrated that NF‑κB DNA‑binding activity was induced by TPA and inhibited by hispolon. In addition, Bay 11‑7082, which is a specific inhibitor of NF‑κB, functioned in a similar manner as hispolon and blocked the secretion and expression of MMP‑9. In conclusion, the results of the present study indicated that hispolon inhibited TPA‑induced migration and invasion of MDA‑MB‑231 cells by reducing the secretion and expression of MMP‑9 through the NF-κB signaling pathway.
